Target identification and Validation resources

Drug targets for human disease emerge from basic research into mechanisms of disease biology Validated molecular drug

targets require that the project team address issues related to Rationale Druggability Mechanism and Safety The

Commercial viability of the approach may also be critical for recruiting industry partners at key junctures to support

development

The Molecular Target is the protein that will bind directly to the proposed drug A validated target has

Rationale

A human genetic or pharmacological link to a selected disease population

bull Modulation of the target has been shown to produce therapeutic benefit in an in vivo animal model of the disease

population or of the relevant circuit dysfunction using a directly translatable and quantifiable endpoint

Druggability

bull A tool compound exists to modulate the target or a family member

bull Biochemical and cellular assays exist to support development of SAR for on-target and off-target activities

Well-Defined Mechanism of Action

bull A clear set of laboratory objectives that specify required mode and degree of target engagement needed for

efficacy

bull Pharmacodynamic measures of target engagement are available to monitor activity in animals and people

bull Disease induced changes in target expression or distribution have been examined

bull Common human SNPs in target documented and functional consequences considered

Safety Risk Assessment

bull Known pharmacological risks associated with target mechanism are documented

bull The tissue distribution of the target is understood in preclinical species humans and patients

bull The most likely off-target activities associated with closest sequence homology are identified and considered for

safety risks

Commercial Potential

bull Competitive differentiation strategy suggests improvement over standard of care

bull Viable intellectual property and product development plan

Resources available at BCH Assay Development Screening Funnel development Chemical compound files Assistance

with identification of academic and industry partners for collaborative SAR campaigns

Identification of the correct molecule requires a clearly defined set of laboratory objectives and a well-designed screening

funnel to select the molecule that will meet those objectives Laboratory objectives for a molecule include specific criteria

for the mode of binding to target (eg agonist partial agonist inverse agonist non-competitive inhibitor) the potency

(eg Ki lt30nM) selectivity (eg gt30X selectivity over family member target XY and Z) brain penetration (yesno) dosing

paradigm ( eg oral once daily intravenous once monthly) and duration of expected treatment (eg sub-chronic daily

treatment for 2 weeks chronic treatment for years) Each of these laboratory objectives will have bearing on the design of

the screening funnel required to identify the molecule

The screening funnel requires a robust high-throughput (HTS) biochemical assay capable of testing gt100000 compounds

good sensitivity (Zrsquogt05) and an appropriate orthogonal assay (usually cell based) to confirm functional activity of the

compound at the target which can be used to weed out false positives and primary HTS artifacts Critical features defined

by the laboratory objectives may require additional in vitro absorption and metabolism data from compounds slated to

progress in vivo to ensure that structure activity relationships being developed will support expected dosing profiles and

target organ disposition A collection of critical off target assays to ensure required selectivity of the candidate drug must

be available to test molecules progressing from functional assays Compounds expected to be tested in vivo will require

pharmacokinetic studies to ensure target organ exposure in concentration ranges needed to support hypothesis testing

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Some web resources for identifying side effects of known compounds httpintsideirbbarcelonaorg

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

NINDS The Blueprint Neurotherapeutics Network (BPN) Provides the neuroscience community access to a complete and

seamless pipeline for preclinical drug development beginning with chemical optimization and concluding after phase I

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Target identification and Validation resources

Drug targets for human disease emerge from basic research into mechanisms of disease biology Validated molecular drug

targets require that the project team address issues related to Rationale Druggability Mechanism and Safety The

Commercial viability of the approach may also be critical for recruiting industry partners at key junctures to support

development

The Molecular Target is the protein that will bind directly to the proposed drug A validated target has

Rationale

A human genetic or pharmacological link to a selected disease population

bull Modulation of the target has been shown to produce therapeutic benefit in an in vivo animal model of the disease

population or of the relevant circuit dysfunction using a directly translatable and quantifiable endpoint

Druggability

bull A tool compound exists to modulate the target or a family member

bull Biochemical and cellular assays exist to support development of SAR for on-target and off-target activities

Well-Defined Mechanism of Action

bull A clear set of laboratory objectives that specify required mode and degree of target engagement needed for

efficacy

bull Pharmacodynamic measures of target engagement are available to monitor activity in animals and people

bull Disease induced changes in target expression or distribution have been examined

bull Common human SNPs in target documented and functional consequences considered

Safety Risk Assessment

bull Known pharmacological risks associated with target mechanism are documented

bull The tissue distribution of the target is understood in preclinical species humans and patients

bull The most likely off-target activities associated with closest sequence homology are identified and considered for

safety risks

Commercial Potential

bull Competitive differentiation strategy suggests improvement over standard of care

bull Viable intellectual property and product development plan

Resources available at BCH Assay Development Screening Funnel development Chemical compound files Assistance

with identification of academic and industry partners for collaborative SAR campaigns

Identification of the correct molecule requires a clearly defined set of laboratory objectives and a well-designed screening

funnel to select the molecule that will meet those objectives Laboratory objectives for a molecule include specific criteria

for the mode of binding to target (eg agonist partial agonist inverse agonist non-competitive inhibitor) the potency

(eg Ki lt30nM) selectivity (eg gt30X selectivity over family member target XY and Z) brain penetration (yesno) dosing

paradigm ( eg oral once daily intravenous once monthly) and duration of expected treatment (eg sub-chronic daily

treatment for 2 weeks chronic treatment for years) Each of these laboratory objectives will have bearing on the design of

the screening funnel required to identify the molecule

The screening funnel requires a robust high-throughput (HTS) biochemical assay capable of testing gt100000 compounds

good sensitivity (Zrsquogt05) and an appropriate orthogonal assay (usually cell based) to confirm functional activity of the

compound at the target which can be used to weed out false positives and primary HTS artifacts Critical features defined

by the laboratory objectives may require additional in vitro absorption and metabolism data from compounds slated to

progress in vivo to ensure that structure activity relationships being developed will support expected dosing profiles and

target organ disposition A collection of critical off target assays to ensure required selectivity of the candidate drug must

be available to test molecules progressing from functional assays Compounds expected to be tested in vivo will require

pharmacokinetic studies to ensure target organ exposure in concentration ranges needed to support hypothesis testing

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Michael J Fox Foundation Therapeutic Pipeline Program Supports Parkinsons disease therapeutic development along the

pre-clinical and clinical path (both drug and non-pharmacological therapeutics including gene therapy biological

surgical and non-invasive approaches) The Michael J Fox Foundation seeks applications with potential for fundamentally

altering disease course andor significantly improving treatment of symptoms above and beyond current standards of care

Proposals must have a well-defined plan for moving toward clinical utility for patients The Therapeutic Pipeline Program is

open to industry and academic investigators proposing novel approaches or repositioning approved or clinically safe

NINDS The Blueprint Neurotherapeutics Network (BPN) Provides the neuroscience community access to a complete and

seamless pipeline for preclinical drug development beginning with chemical optimization and concluding after phase I

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

NeuroNEXT Will establish a consortium of clinical sites capable of forming disease-specific cadres of investigators in order to

develop and implement trials rapidly in a wide range of neurological disorders that affect adults andor children With a

stable and experienced research staff a central IRB model and master trial agreements NeuroNEXT will streamline the

administrative processes for clinical trials and reduce start-up times NeuroNEXT will also be able to design and implement

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

inappropriate dose of drug to test their hypoth-esis It does illustrate that a clear rationale wasnot provided for dose selection in most pub-lications Furthermore all 11 of the 100 publi-cations that measured total brain exposureincluded an author from the pharmaceutical in-dustry (n=5) an academic drug screening group(n = 3) or a pharmacologyndashpharmaceuticalsciences department (n = 3) This observationlikely reflects the limited presence of pharma-cology and pharmacometrics departmentswithinmost academic institutions and limitedaccess to the mass spectrometry and otheranalytical resources needed to measure druglevels in study samples Outsourcing the bio-analysis of samples collected from study ani-mals is feasible but the use of contract researchorganizations to support such studies is oftentoo costly for most academic grant budgets toaccommodate

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Resources available at BCH Assay Development Screening Funnel development Chemical compound files Assistance

with identification of academic and industry partners for collaborative SAR campaigns

Identification of the correct molecule requires a clearly defined set of laboratory objectives and a well-designed screening

funnel to select the molecule that will meet those objectives Laboratory objectives for a molecule include specific criteria

for the mode of binding to target (eg agonist partial agonist inverse agonist non-competitive inhibitor) the potency

(eg Ki lt30nM) selectivity (eg gt30X selectivity over family member target XY and Z) brain penetration (yesno) dosing

paradigm ( eg oral once daily intravenous once monthly) and duration of expected treatment (eg sub-chronic daily

treatment for 2 weeks chronic treatment for years) Each of these laboratory objectives will have bearing on the design of

the screening funnel required to identify the molecule

The screening funnel requires a robust high-throughput (HTS) biochemical assay capable of testing gt100000 compounds

good sensitivity (Zrsquogt05) and an appropriate orthogonal assay (usually cell based) to confirm functional activity of the

compound at the target which can be used to weed out false positives and primary HTS artifacts Critical features defined

by the laboratory objectives may require additional in vitro absorption and metabolism data from compounds slated to

progress in vivo to ensure that structure activity relationships being developed will support expected dosing profiles and

target organ disposition A collection of critical off target assays to ensure required selectivity of the candidate drug must

be available to test molecules progressing from functional assays Compounds expected to be tested in vivo will require

pharmacokinetic studies to ensure target organ exposure in concentration ranges needed to support hypothesis testing

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Michael J Fox Foundation Therapeutic Pipeline Program Supports Parkinsons disease therapeutic development along the

pre-clinical and clinical path (both drug and non-pharmacological therapeutics including gene therapy biological

surgical and non-invasive approaches) The Michael J Fox Foundation seeks applications with potential for fundamentally

altering disease course andor significantly improving treatment of symptoms above and beyond current standards of care

Proposals must have a well-defined plan for moving toward clinical utility for patients The Therapeutic Pipeline Program is

open to industry and academic investigators proposing novel approaches or repositioning approved or clinically safe

NINDS The Blueprint Neurotherapeutics Network (BPN) Provides the neuroscience community access to a complete and

seamless pipeline for preclinical drug development beginning with chemical optimization and concluding after phase I

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Resources available at BCH Assay Development Screening Funnel development Chemical compound files Assistance

with identification of academic and industry partners for collaborative SAR campaigns

Identification of the correct molecule requires a clearly defined set of laboratory objectives and a well-designed screening

funnel to select the molecule that will meet those objectives Laboratory objectives for a molecule include specific criteria

for the mode of binding to target (eg agonist partial agonist inverse agonist non-competitive inhibitor) the potency

(eg Ki lt30nM) selectivity (eg gt30X selectivity over family member target XY and Z) brain penetration (yesno) dosing

paradigm ( eg oral once daily intravenous once monthly) and duration of expected treatment (eg sub-chronic daily

treatment for 2 weeks chronic treatment for years) Each of these laboratory objectives will have bearing on the design of

the screening funnel required to identify the molecule

The screening funnel requires a robust high-throughput (HTS) biochemical assay capable of testing gt100000 compounds

good sensitivity (Zrsquogt05) and an appropriate orthogonal assay (usually cell based) to confirm functional activity of the

compound at the target which can be used to weed out false positives and primary HTS artifacts Critical features defined

by the laboratory objectives may require additional in vitro absorption and metabolism data from compounds slated to

progress in vivo to ensure that structure activity relationships being developed will support expected dosing profiles and

target organ disposition A collection of critical off target assays to ensure required selectivity of the candidate drug must

be available to test molecules progressing from functional assays Compounds expected to be tested in vivo will require

pharmacokinetic studies to ensure target organ exposure in concentration ranges needed to support hypothesis testing

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Michael J Fox Foundation Therapeutic Pipeline Program Supports Parkinsons disease therapeutic development along the

pre-clinical and clinical path (both drug and non-pharmacological therapeutics including gene therapy biological

surgical and non-invasive approaches) The Michael J Fox Foundation seeks applications with potential for fundamentally

altering disease course andor significantly improving treatment of symptoms above and beyond current standards of care

Proposals must have a well-defined plan for moving toward clinical utility for patients The Therapeutic Pipeline Program is

open to industry and academic investigators proposing novel approaches or repositioning approved or clinically safe

therapies from non-PD indications httpswwwmichaeljfoxorgresearchgrant-detailphpid=28

NINDS The Blueprint Neurotherapeutics Network (BPN) Provides the neuroscience community access to a complete and

seamless pipeline for preclinical drug development beginning with chemical optimization and concluding after phase I

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Resources available at BCH Assay Development Screening Funnel development Chemical compound files Assistance

with identification of academic and industry partners for collaborative SAR campaigns

Identification of the correct molecule requires a clearly defined set of laboratory objectives and a well-designed screening

funnel to select the molecule that will meet those objectives Laboratory objectives for a molecule include specific criteria

for the mode of binding to target (eg agonist partial agonist inverse agonist non-competitive inhibitor) the potency

(eg Ki lt30nM) selectivity (eg gt30X selectivity over family member target XY and Z) brain penetration (yesno) dosing

paradigm ( eg oral once daily intravenous once monthly) and duration of expected treatment (eg sub-chronic daily

treatment for 2 weeks chronic treatment for years) Each of these laboratory objectives will have bearing on the design of

the screening funnel required to identify the molecule

The screening funnel requires a robust high-throughput (HTS) biochemical assay capable of testing gt100000 compounds

good sensitivity (Zrsquogt05) and an appropriate orthogonal assay (usually cell based) to confirm functional activity of the

compound at the target which can be used to weed out false positives and primary HTS artifacts Critical features defined

by the laboratory objectives may require additional in vitro absorption and metabolism data from compounds slated to

progress in vivo to ensure that structure activity relationships being developed will support expected dosing profiles and

target organ disposition A collection of critical off target assays to ensure required selectivity of the candidate drug must

be available to test molecules progressing from functional assays Compounds expected to be tested in vivo will require

pharmacokinetic studies to ensure target organ exposure in concentration ranges needed to support hypothesis testing

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Despite widespread use of pharmacologicalagents in mouse models of human diseasethe literature lacks comprehensive pharmaco-kinetic profiles for such studies Coupled witha paucity of suitable data are shortcomingsin the training of experimental biologists inthe application of pharmacometric principlesto experimental study design Many authorssimply cite previously published studies tosupport the selection of a particular dose evenwhen the cited paper lacks drug exposuredata There is an assumption on the part ofresearchers that if a referenced study demon-strates a biological effectmdashthat is any measur-able physiological or behavioral effectmdashin arodent at a given dose then that same dosewill also effectively perturb disease-relevantmechanistic biology in a different study Thedanger occurs when the observed therapeuticeffects are not linked to drug-induced mecha-nistic alterations at the level of the target organLack of a drug exposurendashresponse relationshipin a target organ casts doubt on mechanisticinterpretations In addition any changes inthe route of drug administration vehicle prep-aration species used (rat versus mouse versusprimate) age or strain of animal transgenicmodification time points under investigationduration of dosing or organ targeted for inter-vention (for example brain versus a periph-eral tumor) can alter the relation between doseexposure and measured response In suchcases assumptions regarding the mechanisticbasis for observed therapeutic effects may nothold true

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Resources available at BCH Assay Development Screening Funnel development Chemical compound files Assistance

with identification of academic and industry partners for collaborative SAR campaigns

Identification of the correct molecule requires a clearly defined set of laboratory objectives and a well-designed screening

funnel to select the molecule that will meet those objectives Laboratory objectives for a molecule include specific criteria

for the mode of binding to target (eg agonist partial agonist inverse agonist non-competitive inhibitor) the potency

(eg Ki lt30nM) selectivity (eg gt30X selectivity over family member target XY and Z) brain penetration (yesno) dosing

paradigm ( eg oral once daily intravenous once monthly) and duration of expected treatment (eg sub-chronic daily

treatment for 2 weeks chronic treatment for years) Each of these laboratory objectives will have bearing on the design of

the screening funnel required to identify the molecule

The screening funnel requires a robust high-throughput (HTS) biochemical assay capable of testing gt100000 compounds

good sensitivity (Zrsquogt05) and an appropriate orthogonal assay (usually cell based) to confirm functional activity of the

compound at the target which can be used to weed out false positives and primary HTS artifacts Critical features defined

by the laboratory objectives may require additional in vitro absorption and metabolism data from compounds slated to

progress in vivo to ensure that structure activity relationships being developed will support expected dosing profiles and

target organ disposition A collection of critical off target assays to ensure required selectivity of the candidate drug must

be available to test molecules progressing from functional assays Compounds expected to be tested in vivo will require

pharmacokinetic studies to ensure target organ exposure in concentration ranges needed to support hypothesis testing

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

reference that provides the measured plasma protein binding (PPB) values for many common drugs is provided here

Zhang Xue Shao and Jia (2012) Compilation of 222 drugsrsquo plasma protein binding data and guidance for study designs

Drug Discovery Today Vol 17 Issue 9-10 Pages 476-485 httpwwwncbinlmnihgovpubmed22210121

If your drug target is the brain then you must also understand the kinetics of drug disposition and clearance including blood

brain barrier (BBB) penetration in your test species to select a dose of compound adequate to test your hypothesis

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Patient sample repositoryBiobank Patient registry

Disease processes are dynamic The molecular underpinnings of disease differ between inception progression and

response of the body to disease Thus each stage of disease may require alternative therapeutic strategies Understanding

which stage of disease is best suited to testing a specific therapeutic approach will require information about disease from

patient samples collected at different stages of disease well as an ability to collect and recruit patients at relevant stages of

disease

To locate human RNA profiling data in the public domain from disease samples and tissues at specific stages of disease

search databases referenced in the Correct Target section of this document

The Translational Neuroscience Center offers multiple services that can assist with identification of the correct patients The

Core Repository for Neurological Disorders stores a wide variety of patient samples from many stages of disease The

biorepository is directed by Dr Mustafa Sahin and these samples and de-identified clinical data can be searched and

requested through the Translational Neuroscience Center

The Biobank Core Lab serves as a core resource that ensures top-level specimen handling and services to the Boston

Childrens Hospital research community It serves as both a service core and a biorepository providing an institutional

perspective on the presence of specimens that may be available for use to foster collaborations and accelerate research

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Despite widespread use of pharmacologicalagents in mouse models of human diseasethe literature lacks comprehensive pharmaco-kinetic profiles for such studies Coupled witha paucity of suitable data are shortcomingsin the training of experimental biologists inthe application of pharmacometric principlesto experimental study design Many authorssimply cite previously published studies tosupport the selection of a particular dose evenwhen the cited paper lacks drug exposuredata There is an assumption on the part ofresearchers that if a referenced study demon-strates a biological effectmdashthat is any measur-able physiological or behavioral effectmdashin arodent at a given dose then that same dosewill also effectively perturb disease-relevantmechanistic biology in a different study Thedanger occurs when the observed therapeuticeffects are not linked to drug-induced mecha-nistic alterations at the level of the target organLack of a drug exposurendashresponse relationshipin a target organ casts doubt on mechanisticinterpretations In addition any changes inthe route of drug administration vehicle prep-aration species used (rat versus mouse versusprimate) age or strain of animal transgenicmodification time points under investigationduration of dosing or organ targeted for inter-vention (for example brain versus a periph-eral tumor) can alter the relation between doseexposure and measured response In suchcases assumptions regarding the mechanisticbasis for observed therapeutic effects may nothold true

the target organ run the risk of producing ex-posures that are too low or too high to inter-pret a mechanistic hypothesis Most drugs arenot selective over a large exposure range for asingle molecular target Confident evaluationof a therapeutic hypothesis requires an under-standing of the drugrsquos penetration and kineticswithin the target tissue as well as its potencyand selectivity for specific molecular targetsFurther investigators must consider the con-centration of the unbound fraction of drugthat is available to interact with the targetPublished reports often overlook the fact thatmany small molecules are more than 90bound to plasma or tissue proteins whichgreatly decreases the fraction of drug availableto bind to the intended target Thus in casesin which drug binding has a slow off-rate anorganismrsquos total drug exposure is not a predic-tor of drug available to interact with its target(1) The failure of some academic scientists toobtain relevant pharmacokinetic data impairsthe interpretation of preclinical research resultsand likely contributes to the acknowledgeddifficulties in replicating some academic liter-ature as reported by industry scientists (2 3)

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

inappropriate dose of drug to test their hypoth-esis It does illustrate that a clear rationale wasnot provided for dose selection in most pub-lications Furthermore all 11 of the 100 publi-cations that measured total brain exposureincluded an author from the pharmaceutical in-dustry (n=5) an academic drug screening group(n = 3) or a pharmacologyndashpharmaceuticalsciences department (n = 3) This observationlikely reflects the limited presence of pharma-cology and pharmacometrics departmentswithinmost academic institutions and limitedaccess to the mass spectrometry and otheranalytical resources needed to measure druglevels in study samples Outsourcing the bio-analysis of samples collected from study ani-mals is feasible but the use of contract researchorganizations to support such studies is oftentoo costly for most academic grant budgets toaccommodate

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

reference that provides the measured plasma protein binding (PPB) values for many common drugs is provided here

Drug Discovery Today Vol 17 Issue 9-10 Pages 476-485 httpwwwncbinlmnihgovpubmed22210121

If your drug target is the brain then you must also understand the kinetics of drug disposition and clearance including blood

brain barrier (BBB) penetration in your test species to select a dose of compound adequate to test your hypothesis

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Humans are diverse Not only do patients come in different sizes ages genders and ethnic backgrounds but the same

disease diagnosis often develops in people as a function of different environmental insults and genetic predispositions

Finding biomarkers that will segregate similarly diagnosed patients into subsets of biologically more homogenous

Patient sample repositoryBiobank Patient registry

Disease processes are dynamic The molecular underpinnings of disease differ between inception progression and

response of the body to disease Thus each stage of disease may require alternative therapeutic strategies Understanding

which stage of disease is best suited to testing a specific therapeutic approach will require information about disease from

patient samples collected at different stages of disease well as an ability to collect and recruit patients at relevant stages of

disease

To locate human RNA profiling data in the public domain from disease samples and tissues at specific stages of disease

search databases referenced in the Correct Target section of this document

The Translational Neuroscience Center offers multiple services that can assist with identification of the correct patients The

Core Repository for Neurological Disorders stores a wide variety of patient samples from many stages of disease The

biorepository is directed by Dr Mustafa Sahin and these samples and de-identified clinical data can be searched and

requested through the Translational Neuroscience Center

The Biobank Core Lab serves as a core resource that ensures top-level specimen handling and services to the Boston

Childrens Hospital research community It serves as both a service core and a biorepository providing an institutional

perspective on the presence of specimens that may be available for use to foster collaborations and accelerate research

and discovery

database All studies in the clinical trials data base are required to describe the study design the endpoints under

evaluation and the treatments as well as links to publications of the studies The studies can be searched by topic This can

be a good way to find historical data to help you evaluate variability of endpoint measures in clinical populations This will

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Some web resources for identifying side effects of known compounds httpintsideirbbarcelonaorg

Once a potential clinical candidate molecule is identified GLP-qualified toxicology studies must be carried out with a

qualified vendor to support regulatory filings of an Investigational New Drug (IND) application For a short tutorial on studies

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

your work according to standards that will support patent applications

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Despite widespread use of pharmacologicalagents in mouse models of human diseasethe literature lacks comprehensive pharmaco-kinetic profiles for such studies Coupled witha paucity of suitable data are shortcomingsin the training of experimental biologists inthe application of pharmacometric principlesto experimental study design Many authorssimply cite previously published studies tosupport the selection of a particular dose evenwhen the cited paper lacks drug exposuredata There is an assumption on the part ofresearchers that if a referenced study demon-strates a biological effectmdashthat is any measur-able physiological or behavioral effectmdashin arodent at a given dose then that same dosewill also effectively perturb disease-relevantmechanistic biology in a different study Thedanger occurs when the observed therapeuticeffects are not linked to drug-induced mecha-nistic alterations at the level of the target organLack of a drug exposurendashresponse relationshipin a target organ casts doubt on mechanisticinterpretations In addition any changes inthe route of drug administration vehicle prep-aration species used (rat versus mouse versusprimate) age or strain of animal transgenicmodification time points under investigationduration of dosing or organ targeted for inter-vention (for example brain versus a periph-eral tumor) can alter the relation between doseexposure and measured response In suchcases assumptions regarding the mechanisticbasis for observed therapeutic effects may nothold true

the target organ run the risk of producing ex-posures that are too low or too high to inter-pret a mechanistic hypothesis Most drugs arenot selective over a large exposure range for asingle molecular target Confident evaluationof a therapeutic hypothesis requires an under-standing of the drugrsquos penetration and kineticswithin the target tissue as well as its potencyand selectivity for specific molecular targetsFurther investigators must consider the con-centration of the unbound fraction of drugthat is available to interact with the targetPublished reports often overlook the fact thatmany small molecules are more than 90bound to plasma or tissue proteins whichgreatly decreases the fraction of drug availableto bind to the intended target Thus in casesin which drug binding has a slow off-rate anorganismrsquos total drug exposure is not a predic-tor of drug available to interact with its target(1) The failure of some academic scientists toobtain relevant pharmacokinetic data impairsthe interpretation of preclinical research resultsand likely contributes to the acknowledgeddifficulties in replicating some academic liter-ature as reported by industry scientists (2 3)

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

and free to interact with the molecular targetFurthermore most studies used evidence of abiological activity to justify dose selection with-out consideration for how exposure of theagent relates to the potency of the compoundat known molecular targets which would berequired to test a mechanistic hypothesis

The lack of pharmacokinetic considera-tion does not imply that every study used an

inappropriate dose of drug to test their hypoth-esis It does illustrate that a clear rationale wasnot provided for dose selection in most pub-lications Furthermore all 11 of the 100 publi-cations that measured total brain exposureincluded an author from the pharmaceutical in-dustry (n=5) an academic drug screening group(n = 3) or a pharmacologyndashpharmaceuticalsciences department (n = 3) This observationlikely reflects the limited presence of pharma-cology and pharmacometrics departmentswithinmost academic institutions and limitedaccess to the mass spectrometry and otheranalytical resources needed to measure druglevels in study samples Outsourcing the bio-analysis of samples collected from study ani-mals is feasible but the use of contract researchorganizations to support such studies is oftentoo costly for most academic grant budgets toaccommodate

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

The repurposing of statins illustrateshow the neuroPK knowledge gap limits progressStatins were developed as 3-hydroxy-3-methylglutarylndashcoenzyme A (HMG-CoA) reduc-tase inhibitors to lower cholesterol and reduce

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Some web resources for identifying side effects of known compounds httpintsideirbbarcelonaorg

Once a potential clinical candidate molecule is identified GLP-qualified toxicology studies must be carried out with a

Laboratory notebook best practices TIDO office

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

your work according to standards that will support patent applications

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

NINDS The Blueprint Neurotherapeutics Network (BPN) Provides the neuroscience community access to a complete and

seamless pipeline for preclinical drug development beginning with chemical optimization and concluding after phase I

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

inappropriate dose of drug to test their hypoth-esis It does illustrate that a clear rationale wasnot provided for dose selection in most pub-lications Furthermore all 11 of the 100 publi-cations that measured total brain exposureincluded an author from the pharmaceutical in-dustry (n=5) an academic drug screening group(n = 3) or a pharmacologyndashpharmaceuticalsciences department (n = 3) This observationlikely reflects the limited presence of pharma-cology and pharmacometrics departmentswithinmost academic institutions and limitedaccess to the mass spectrometry and otheranalytical resources needed to measure druglevels in study samples Outsourcing the bio-analysis of samples collected from study ani-mals is feasible but the use of contract researchorganizations to support such studies is oftentoo costly for most academic grant budgets toaccommodate

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

reference that provides the measured plasma protein binding (PPB) values for many common drugs is provided here

If your drug target is the brain then you must also understand the kinetics of drug disposition and clearance including blood

brain barrier (BBB) penetration in your test species to select a dose of compound adequate to test your hypothesis

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Patient sample repositoryBiobank Patient registry

Disease processes are dynamic The molecular underpinnings of disease differ between inception progression and

response of the body to disease Thus each stage of disease may require alternative therapeutic strategies Understanding

which stage of disease is best suited to testing a specific therapeutic approach will require information about disease from

patient samples collected at different stages of disease well as an ability to collect and recruit patients at relevant stages of

disease

To locate human RNA profiling data in the public domain from disease samples and tissues at specific stages of disease

search databases referenced in the Correct Target section of this document

The Translational Neuroscience Center offers multiple services that can assist with identification of the correct patients The

Core Repository for Neurological Disorders stores a wide variety of patient samples from many stages of disease The

biorepository is directed by Dr Mustafa Sahin and these samples and de-identified clinical data can be searched and

requested through the Translational Neuroscience Center

The Biobank Core Lab serves as a core resource that ensures top-level specimen handling and services to the Boston

Childrens Hospital research community It serves as both a service core and a biorepository providing an institutional

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Terms that relate to Targets Molecular target- the protein that binds drug to produce efficacy Off-Target- other proteins that bind the drug that do not relate to efficacy and may produce Adverse Events (AEs) Druggable target ndashcomes from a class of proteins that has successfully been targeted with small molecule drugs in

the past Primarily transporters enzymes receptors ion channels (Not protein-protein interactions transcription factors RNA binding proteins etc)

Druggable genome- about 3000 genes encoding all druggable proteins Druggability- the presence of protein folds (quarternary structures) that favor specific interactions with drug-like

molecules Exploratory target- Hypothesis that a modulating a target via a particular mode of action will be beneficial to a

particular patient population Validated target- Hypothesis regarding a target also has in vivo efficacy data for a disease or a disease model- along

with a complete understanding of how the target mechanism relates to disease- (also called lsquoProof of Principlersquo) Phenotypic screen- a screen for compounds that will reverse a phenotype the molecular target may not be known Systems pharmacology target(s)-a precisely defined combination or lsquofingerprintrsquo of molecular targets to be

modulated to correct a phenotype (Poly-pharmacology)

Despite widespread use of pharmacologicalagents in mouse models of human diseasethe literature lacks comprehensive pharmaco-kinetic profiles for such studies Coupled witha paucity of suitable data are shortcomingsin the training of experimental biologists inthe application of pharmacometric principlesto experimental study design Many authorssimply cite previously published studies tosupport the selection of a particular dose evenwhen the cited paper lacks drug exposuredata There is an assumption on the part ofresearchers that if a referenced study demon-strates a biological effectmdashthat is any measur-able physiological or behavioral effectmdashin arodent at a given dose then that same dosewill also effectively perturb disease-relevantmechanistic biology in a different study Thedanger occurs when the observed therapeuticeffects are not linked to drug-induced mecha-nistic alterations at the level of the target organLack of a drug exposurendashresponse relationshipin a target organ casts doubt on mechanisticinterpretations In addition any changes inthe route of drug administration vehicle prep-aration species used (rat versus mouse versusprimate) age or strain of animal transgenicmodification time points under investigationduration of dosing or organ targeted for inter-vention (for example brain versus a periph-eral tumor) can alter the relation between doseexposure and measured response In suchcases assumptions regarding the mechanisticbasis for observed therapeutic effects may nothold true

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

inappropriate dose of drug to test their hypoth-esis It does illustrate that a clear rationale wasnot provided for dose selection in most pub-lications Furthermore all 11 of the 100 publi-cations that measured total brain exposureincluded an author from the pharmaceutical in-dustry (n=5) an academic drug screening group(n = 3) or a pharmacologyndashpharmaceuticalsciences department (n = 3) This observationlikely reflects the limited presence of pharma-cology and pharmacometrics departmentswithinmost academic institutions and limitedaccess to the mass spectrometry and otheranalytical resources needed to measure druglevels in study samples Outsourcing the bio-analysis of samples collected from study ani-mals is feasible but the use of contract researchorganizations to support such studies is oftentoo costly for most academic grant budgets toaccommodate

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Pharmacokinetic tutorial drug exposure measurement services pharmacokinetic data references

Selecting the correct dose to achieve exposure of drug that are adequate to test a hypothesis in preclinical species

requires that you know the potency of the molecule at the desired drug target and the dose of compound required to

achieve target organ exposure that will result in the free (not bound by protein) concentration of drug required to engage

the molecular target within the target organ compartment Estimates of Drug potency can be found in many of the

databases listed under correct molecule The free concentration of a drug is determined in the plasma by multiplying the

concentration of drug in the plasma by the fraction unbound This must be measured for each compound A literature

reference that provides the measured plasma protein binding (PPB) values for many common drugs is provided here

Zhang Xue Shao and Jia (2012) Compilation of 222 drugsrsquo plasma protein binding data and guidance for study designs

Drug Discovery Today Vol 17 Issue 9-10 Pages 476-485 httpwwwncbinlmnihgovpubmed22210121

If your drug target is the brain then you must also understand the kinetics of drug disposition and clearance including blood

brain barrier (BBB) penetration in your test species to select a dose of compound adequate to test your hypothesis

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Patient sample repositoryBiobank Patient registry

Disease processes are dynamic The molecular underpinnings of disease differ between inception progression and

response of the body to disease Thus each stage of disease may require alternative therapeutic strategies Understanding

which stage of disease is best suited to testing a specific therapeutic approach will require information about disease from

patient samples collected at different stages of disease well as an ability to collect and recruit patients at relevant stages of

disease

To locate human RNA profiling data in the public domain from disease samples and tissues at specific stages of disease

search databases referenced in the Correct Target section of this document

The Translational Neuroscience Center offers multiple services that can assist with identification of the correct patients The

Core Repository for Neurological Disorders stores a wide variety of patient samples from many stages of disease The

biorepository is directed by Dr Mustafa Sahin and these samples and de-identified clinical data can be searched and

requested through the Translational Neuroscience Center

The Biobank Core Lab serves as a core resource that ensures top-level specimen handling and services to the Boston

Childrens Hospital research community It serves as both a service core and a biorepository providing an institutional

perspective on the presence of specimens that may be available for use to foster collaborations and accelerate research

and discovery

account the variability of the endpoint being measured Statistical support for preclinical studies is available on a

department by department basis Neurology and Neurobiology requests for preclinical biostatistics support can be made

through the CRC website

httpredcap-qiredcap_edcsurveyss=Rma5u83qKC

Clinical statistical support for all departments is also available through the CRC Design and Analysis Core For more

information contact Michael Monuteaux michaelmonuteauxchildrensharvardedu

Clinical datasets that provide data for supporting power calculations can be found by searching through clinical trialsgov

database All studies in the clinical trials data base are required to describe the study design the endpoints under

evaluation and the treatments as well as links to publications of the studies The studies can be searched by topic This can

be a good way to find historical data to help you evaluate variability of endpoint measures in clinical populations This will

be needed to support sample size power calculations httpsclinicaltrialsgov

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Some web resources for identifying side effects of known compounds httpintsideirbbarcelonaorg

Once a potential clinical candidate molecule is identified GLP-qualified toxicology studies must be carried out with a

qualified vendor to support regulatory filings of an Investigational New Drug (IND) application For a short tutorial on studies

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

your work according to standards that will support patent applications

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Drug Repurposing Drug Repurposing is a strategic pillar of the National Center for Advancing Translational Science (NCATS)

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

An independent witness ie someone who understands the technology but will not benamed as a co-inventor of the invention should sign and date each entry after the state-ment ldquoRead and understood by rdquo (The witness should preferably sign theentries on a contemporaneous or fairly contemporaneous basis but entries can also bereviewed signed and dated on a periodic eg weekly or monthly basis)

3 mdash Do use inkNotebook entries should be made in ink and in chronological order Entries should not beerased or ldquowhited outrdquo If an entry contains an error a line should be drawn through theerror and new text should continue in the next available space

4 mdash Donrsquot leave blank spacesBlank gaps between entries should be avoided If a blank space is left on a page a line orcross should be drawn through the blank space and the page dated to prevent subsequententries

5 mdash Donrsquot modifyPrior entries should not be modified at a later date If data were omitted the new datacan be entered under a new date and cross-referenced to the previous entry Record exper-iments when they are performed

6 mdash Do use past tenseUse the past tense (eg ldquowas heatedrdquo) to describe the experiments that were actually performed

the target organ run the risk of producing ex-posures that are too low or too high to inter-pret a mechanistic hypothesis Most drugs arenot selective over a large exposure range for asingle molecular target Confident evaluationof a therapeutic hypothesis requires an under-standing of the drugrsquos penetration and kineticswithin the target tissue as well as its potencyand selectivity for specific molecular targetsFurther investigators must consider the con-centration of the unbound fraction of drugthat is available to interact with the targetPublished reports often overlook the fact thatmany small molecules are more than 90bound to plasma or tissue proteins whichgreatly decreases the fraction of drug availableto bind to the intended target Thus in casesin which drug binding has a slow off-rate anorganismrsquos total drug exposure is not a predic-tor of drug available to interact with its target(1) The failure of some academic scientists toobtain relevant pharmacokinetic data impairsthe interpretation of preclinical research resultsand likely contributes to the acknowledgeddifficulties in replicating some academic liter-ature as reported by industry scientists (2 3)

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

to plasma or brain proteins on the free expo-sure of drug available to interact with the tar-get This is a critical flaw in most publishedstudies that use small molecules for functionaleffects in the brain because many centralnervous system (CNS) drugs that penetratethe blood-brain barrier exhibit high proteinbinding leaving a small fraction of the totaldrug measured in plasma or brain unbound

and free to interact with the molecular targetFurthermore most studies used evidence of abiological activity to justify dose selection with-out consideration for how exposure of theagent relates to the potency of the compoundat known molecular targets which would berequired to test a mechanistic hypothesis

The lack of pharmacokinetic considera-tion does not imply that every study used an

inappropriate dose of drug to test their hypoth-esis It does illustrate that a clear rationale wasnot provided for dose selection in most pub-lications Furthermore all 11 of the 100 publi-cations that measured total brain exposureincluded an author from the pharmaceutical in-dustry (n=5) an academic drug screening group(n = 3) or a pharmacologyndashpharmaceuticalsciences department (n = 3) This observationlikely reflects the limited presence of pharma-cology and pharmacometrics departmentswithinmost academic institutions and limitedaccess to the mass spectrometry and otheranalytical resources needed to measure druglevels in study samples Outsourcing the bio-analysis of samples collected from study ani-mals is feasible but the use of contract researchorganizations to support such studies is oftentoo costly for most academic grant budgets toaccommodate

DATABASES AND REPURPOSINGRecent years have seen increasing efforts toinvestigate approved or clinically tested drugsfor new indications (4ndash8) Such repurposinghas been touted as a means to accelerate ther-apeutic development (4) For example a stra-tegic pillar of the US National Institutes ofHealthrsquos (NIHrsquos) translational roadmap callsfor the academic community to actively par-ticipate in the repurposing of drugs approvedby the US Food and Drug Administration(FDA) or investigational drugs that havepassed safety hurdles but failed in clinicaltrials because of lack of efficacy (9ndash11) To havea meaningful impact in neurological and psy-chiatric disorders such drug repurposingefforts will require access to neuropharma-cokinetic (neuroPK) data sets in mice to guidethe testing of new therapeutic hypotheses ingenetically engineered disease models A re-cently published consensus evaluation of drugrepositioning opportunities for Alzheimerrsquosdisease identified 15 potential drug candidatesThese were further prioritized for testing onthe basis of available evidence to produce ashortlist of seven compounds reviewed by in-dustry experts to provide insight into the via-bility of these candidates The most commonshortcoming identified for the compoundsconsidered were issues related to insufficientbrain penetration or the lack of informationabout optimal dosing strategies (11)

The repurposing of statins illustrateshow the neuroPK knowledge gap limits progressStatins were developed as 3-hydroxy-3-methylglutarylndashcoenzyme A (HMG-CoA) reduc-tase inhibitors to lower cholesterol and reduce

Table 1 Preclinical dosing strategies The rationale for drug-dosing strategies was extractedfrom the literature through the analysis of 100 peer-reviewed studies published in2014 from eight journals that cover research on mechanisms of brain function disease andtherapeutic approaches to CNS disorders (Cell Neuron Nature Nature Neuroscience NatureMedicine Neurobiology of Disease Neuropsychopharmacology and Science TranslationalMedicine) (table S1) Forty-four of the 100 publications selected were studies of potentialtherapeutic approaches to disease whereas the remaining were studies of basic neurobiology ormechanisms of disease Each publication was examined to discern how authors selected thedosage of pharmacological tools or therapeutic compounds used in the design of studies toprobe brain function A relatively small number of studies considered what the concentrationof drug available in the brain after administration would be in the context of theirexperimental studies The most common method for selecting a dose of drug was tocite a previous study that demonstrated a biological effect of the drug on someaspect of rodent behavior

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources

Formulations advice and assistance with preclinical drug delivery Neurodevelopmental Behavioral Core

To effectively deliver drug to preclinical species for the duration of a study researchers must choose a dose a formulation

and a route of administration that will support target organ exposure long enough to test a therapeutic hypothesis Since

most drugs developed for humans are optimized for human metabolism parameters many compounds developed for

humans are rapidly metabolized and cleared in rodents requiring alternative formulations and routes of preclinical

administration (see tutorial under Correct Dose)

Proper formulation of drugs and vehicles to ensure appropriate drug exposure is a critical factor in preclinical study design

The Neurodevelopmental Behavioral Core may provide advice on standard formulations Preclinical assistance and

training across many routes of administration including IV cannulation osmotic minipumps oral gavage sc and ip is also

available through the Neurodevelopmental Behavioral Core

Patient sample repositoryBiobank Patient registry

Disease processes are dynamic The molecular underpinnings of disease differ between inception progression and

response of the body to disease Thus each stage of disease may require alternative therapeutic strategies Understanding

which stage of disease is best suited to testing a specific therapeutic approach will require information about disease from

patient samples collected at different stages of disease well as an ability to collect and recruit patients at relevant stages of

disease

To locate human RNA profiling data in the public domain from disease samples and tissues at specific stages of disease

search databases referenced in the Correct Target section of this document

The Translational Neuroscience Center offers multiple services that can assist with identification of the correct patients The

Core Repository for Neurological Disorders stores a wide variety of patient samples from many stages of disease The

biorepository is directed by Dr Mustafa Sahin and these samples and de-identified clinical data can be searched and

requested through the Translational Neuroscience Center

The Biobank Core Lab serves as a core resource that ensures top-level specimen handling and services to the Boston

Childrens Hospital research community It serves as both a service core and a biorepository providing an institutional

perspective on the presence of specimens that may be available for use to foster collaborations and accelerate research

and discovery

Understanding RDoC Human Neurobehavioral Core Service IRB assistance with clinical protocols

Different stages of clinical trials have different goals for selecting endpoints Early stage clinical trials are typically in search

of a translatable pharmacodynamic or target engagement endpoint to ensure that the molecule in question will be

competent to test a clinical hypothesis in humans Developing translatable measures of target engagement in preclinical

species and humans is critical to developing data sets that will enable subsequent therapeutic efficacy trials The earliest

trials require endpoints that can be measured in a functionally equivalent manner across species Therefore it is critical for

preclinical researchers to develop dose-responsive data sets in preclinical species using quantitative endpoints such as EEG

visual or auditory evoked potentials PET ligands plasma or CSF based biochemical measures or translatable task based

behaviors Preclinical data must be a developed with an eye towards what the equivalent measure will be in the clinic

Toward that end the NIMH has initiated the Research Domain Criteria (RDoC) that is aimed at characterizing mental health

disorders across many different dimensions across species A big focus of the RDoC initiative is the identification of

translatable endpoints for evaluating pharmacodynamics and efficacy in Neuroscience Drug Discovery Preclinical

Neuroscience researchers should be familiar with the RDoC framework For advice on in vivo characterization of preclinical

endpoints with translational potential for Neuroscience related disorders contact Dr Robin Kleiman at the TNC

Body atlases for expression of mRNA and protein guides to chemical alerts guidance for preclinical toxicology studies for

Investigational New Drug (IND) applications

Discovery scientists must consider the distribution of the proposed drug target across the entire body in human samples in

order to understand potential safety risks to be monitored during preclinical toxicological testing Teams also have to be

aware of differences in distribution of the target and related family members in preclinical species Many of the target

expression databases listed in the Correct Target section of this document are useful in this regard Assays that can be used

to monitor any potential safety risks are critical to the development of a suitable testing funnel needed to advance

compounds

Many chemical classes of compounds that are identified in screens are not suitable for drug development due to the

presence of structural alerts that are known to cause chemical toxicity Databases that house information of structural alerts

can be used to de-prioritize structural series early in the life of a program Some toxicology databases that can help

deprioritize toxic chemotypes include httppubsacsorgdoiabs101021ci300245q

Some web resources for identifying side effects of known compounds httpintsideirbbarcelonaorg

Once a potential clinical candidate molecule is identified GLP-qualified toxicology studies must be carried out with a

qualified vendor to support regulatory filings of an Investigational New Drug (IND) application For a short tutorial on studies

Translation of basic research into new marketed drugs will require a transition from exploring scientific principles and testing

hypotheses into commercial products Industry partners capable of developing these potential products need to be able

to license the intellectual property required to sell the product in order to justify investment in building programs around new

ideas This requires that scientific researchers protect and patent potential inventions from their work to enable future

commercialization by partners with appropriate expertise To ensure that researchers are appropriately documenting their

work in a manner that will support preservation of intellectual property all investigators are encouraged to consult with TIDO

before any public disclosures of new research Similarly the following documentation provides guidance for documenting

your work according to standards that will support patent applications

A phenotypic screen requires a biologically robust assay that represents a significant aspect of disease-relevant human

biology It can be used to identify molecular targets for target validation studies through the use of well-annotated

bioactive molecules or genomic libraries (eg RNAi CRISPER) Alternatively phenotypic screens can be used to identify

novel compounds that must subsequently be lsquoDE convolutedrsquo to identify novel targets using lsquowarheadsrsquo These screens rely

on identification and manipulation of a functional deficit or phenotype using a patient-derived cellular system

The strengths of this approach

Use of human systems can improve translatability

Identified compounds may empirically balance therapeutic activity at multiple required targets

Well-suited to drug repurposing

Phenotypic screens can be used to identify compounds or targets for mechanism based drug discovery programs

Many CNS drugs have been discovered using a phenotypic repurposing screen (Swinney and Anthony 2011)

Drawbacks to this approach

Assays are slow low throughput and more expensive as compared to cell-free assays

Cell-based assays may not predict circuit level or brain phenotypes

Furthermore as a primary screening approach

Precludes leveraging strengths in uHTS SBDD and parallel design

Every molecule must be de-risked independently thus safety can be very hard to predict

Michael J Fox Foundation Therapeutic Pipeline Program Supports Parkinsons disease therapeutic development along the

pre-clinical and clinical path (both drug and non-pharmacological therapeutics including gene therapy biological

surgical and non-invasive approaches) The Michael J Fox Foundation seeks applications with potential for fundamentally

altering disease course andor significantly improving treatment of symptoms above and beyond current standards of care

Proposals must have a well-defined plan for moving toward clinical utility for patients The Therapeutic Pipeline Program is

open to industry and academic investigators proposing novel approaches or repositioning approved or clinically safe

therapies from non-PD indications httpswwwmichaeljfoxorgresearchgrant-detailphpid=28

NINDS The Blueprint Neurotherapeutics Network (BPN) Provides the neuroscience community access to a complete and

seamless pipeline for preclinical drug development beginning with chemical optimization and concluding after phase I

clinical trials Participants in the BPN will receive funding to conduct bioactivity and efficacy testing in their own laboratories

as well as access to millions of dollars in NIH-contracted drug development services including medicinal chemistry

pharmacology toxicology and phase 1 clinical trials NIH will also provide drug development consultants who have had

years of experience working at a senior level in industry Because the Blueprint is establishing a network of drug

development service providers that typically cater to biopharmaceutical companies neuroscientists who join the BPN can

readily plug in to all of the drug development expertise that typically resides in industry The projects supported through the

network will be highly collaborative and the researchers who initiate the projects will serve as the principal investigators

(PIs) directing their projects through the development pipeline with the help of industry consultants The PIs and their

institutions will have the opportunity to attain assignment of intellectual property rights from all other network participants

who may have intellectual input into their projects This will allow the PIs to retain control of the intellectual property for drug

candidates developed through the network and eventually pursue licensing and commercialization partnerships

NeuroNEXT Will establish a consortium of clinical sites capable of forming disease-specific cadres of investigators in order to

develop and implement trials rapidly in a wide range of neurological disorders that affect adults andor children With a

stable and experienced research staff a central IRB model and master trial agreements NeuroNEXT will streamline the

administrative processes for clinical trials and reduce start-up times NeuroNEXT will also be able to design and implement

Despite widespread use of pharmacologicalagents in mouse models of human diseasethe literature lacks comprehensive pharmaco-kinetic profiles for such studies Coupled witha paucity of suitable data are shortcomingsin the training of experimental biologists inthe application of pharmacometric principlesto experimental study design Many authorssimply cite previously published studies tosupport the selection of a particular dose evenwhen the cited paper lacks drug exposuredata There is an assumption on the part ofresearchers that if a referenced study demon-strates a biological effectmdashthat is any measur-able physiological or behavioral effectmdashin arodent at a given dose then that same dosewill also effectively perturb disease-relevantmechanistic biology in a different study Thedanger occurs when the observed therapeuticeffects are not linked to drug-induced mecha-nistic alterations at the level of the target organLack of a drug exposurendashresponse relationshipin a target organ casts doubt on mechanisticinterpretations In addition any changes inthe route of drug administration vehicle prep-aration species used (rat versus mouse versusprimate) age or strain of animal transgenicmodification time points under investigationduration of dosing or organ targeted for inter-vention (for example brain versus a periph-eral tumor) can alter the relation between doseexposure and measured response In suchcases assumptions regarding the mechanisticbasis for observed therapeutic effects may nothold true

Drug discovery teams in industry settingsroutinely collect pharmacokinetic data to aidin the mechanistic interpretation of in vivopreclinical data and to project optimal dosingparadigms for efficacy and toxicology studiesData required to evaluate brain penetrationare not typically collected by industry-baseddrug-discovery teams for compounds origi-nally developed for therapeutic indicationsthat do not obviously implicate the centralnervous system making this information es-pecially hard to find for many otherwise well-described drugs In addition because mousedata are not required for preclinical toxicologystudies (the more common small animal spe-cies for preclinical toxicology being rats)industry scientists do not often obtain pharma-cokinetic data from mouse experiments These

issues are especially relevant for older drugsthat are potentially suitable for repurposingMany older drugs were discovered and char-acterized before routine pharmacokinetic-pharmacodynamic (PK-PD) modeling ofpreclinical drug exposure and its applicationto predicting human dosing became standardpractice Last pharmacokinetic data are notconsidered innovative and these studies gen-erally do not achieve publication in peer-reviewed journals even when the data havebeen generated When such data are pub-lished it is often relegated to the unsearchableblack hole of supplementary materials Thusmouse neuroPK profiles are not readily avail-able for many drugs that are frequently usedin conjunction with mouse models of humanbrain disorders

DOCUMENTING DOSING STRATEGIES

To evaluate the potential impact of insufficientpharmacokinetic data on dose selection in asample of recent published neuroscience liter-ature we conducted an analysis of papersidentified by means of a PubMed search usingthe search terms ldquodrugrdquo and ldquobrainrdquo for the pub-lication year 2014 from eight journals (Table 1)This list was culled to include only primaryresearch reports that included systemic adminis-tration of a pharmacological agent a pharma-cological therapeutic or a biological therapeuticas part of the study design The search yielded100 articles published between 1 January and30 December 2014 that used systemic drug de-livery with the intended goal of targeting thebrain of rodents (table S1) Each publicationwas examined for the stated rationale behindthe dose selection of study drugs (Table 1)

The reported rationale for dosing strategiesfell into several broad categories including(from lowest confidence to highest) (i) dose se-lected rationale not discussed (ii) literaturecitations of another study in which reportsranged from citation of exposure in the samespecies exposure in a different strain or spe-cies a dose conversion from the human liter-ature to rodent or reports of effects on rodentbehavior in another study (iii) demonstrationof an effect on rodent behavior or function inthe current study (iv) demonstration of adose-responsive biological effect in the currentstudy (v) measurement of drug levels in bloodor plasma in the current study and (vi) mea-surement of drug levels in the target organ(that is the brain) in the current study In onlytwo instances were publications identifiedthat considered the impact of drug binding

risk of cardiovascular disease (12) FDA hasapproved at least nine different statins andmost are commonly prescribed nearly one-third of Americans ages 55 to 64 took a pre-scription cholesterol-lowering drug between2009 and 2012 (wwwcdcgovnchsdatahushus14pdf) The widespread availability andsafety profile of statins has lured researchersinto evaluating their potential for repurpos-ing (13) Statins have been profiled extensive-ly in preclinical research to test for potentialtherapeutic benefit in Alzheimerrsquos disease(14ndash19) Fragile X syndrome (20) Rett syn-drome (21 22) epilepsy (23) Huntingtonrsquos dis-ease (24) Parkinsonrsquos disease (25 26) stroke(27) and brain injury (28 29)

A search of the literature reveals no sys-tematic neuroPK studies in any mouse strainthat would enable direct comparisons of CNSexposure across the various statins In silicopredictions based on the drugsrsquo molecularproperties suggest that the nine most widelyprescribed statins each have a different poten-tial to penetrate the blood-brain barrier differ-ent potencies against the HMG-CoA reductaseenzyme and different ldquooff-targetrdquo activity pro-files (30) On the basis of available data thereis reason to believe that simvastatin has thebest overall profile for inhibiting HMG-CoAreductase in the brain (30) A recent study re-ported that lovastatin is able to reverse a rangeof phenotypes in a mouse model of Fragile Xsyndrome (20) However the design of an op-timal clinical trial will require the collection ofmouse pharmacokinetic data to understandhow much CNS drug exposure is required toproduce efficacy in the disease model Thereare at least two possible scenarios Giventhat simvastatin is more potent at inhibitingHMG-CoA reductase than are other statinsand likely to be more brain penetrant inboth mice and humans one would expectthat simvastatin will be more potent than lo-vastatin in ameliorating symptoms in bothmice and humans if the observed efficacy stemsfrom inhibition of HMG-CoA reductase activ-ity in the brain by lovastatin The advantage ofthis outcome would be that better brain pen-etration and potency would lead to a loweroverall dose requirement to achieve efficacyand thus likely a better safety profile

A second scenario could be that lovastatin ismore potent than simvastatin in the mousemodel of Fragile X syndrome because of anadditional biological activity inherent to thelovastatinmolecule whichmaynot yet be doc-umented in the literature In either case un-derstanding the CNS exposure of lovastatin

required to produce efficacy in themouse willdetermine whether there is a safe therapeuticindex for achieving the required concentra-tion in patients Previous attempts to discernuseful neuroPK parameters from the litera-ture for the use of statins in rodent modelshave highlighted the lack of critical data asthe looming roadblock to progress in the field(31 32) Until these data exist the transla-tional potential of preclinical research maybe limited And this is but one example ofone drug class

The creation of a centralized database isneeded for the entire translational researchcommunity and would establish a new mech-anism for academia funding agencies founda-tions and industry to pool resources If studiesare donewell the first time and documented inan open-access resource it will reduce redun-dant efforts and improve the quality of decisionmaking by scientists considering innovativesolutions to our biggest health problems

A central repository that contains brainpenetration protein binding and pharmaco-kinetic profiles of drugs and pharmacologicaltools in rodents is needed to effectively sup-port translational research This databaseshould also provide basic tutorials that de-fine primary pharmacokinetic parameterswith examples to illustrate how data are usedto predict optimal dosing strategies The min-imum data set needed for each compoundin a useful rodent database is highlighted inTable 2 Access to this information and sup-porting materials will have an immediateimpact on the quality of translational drug re-purposing efforts across brain disorders andwill support the development of new thera-peutic approaches to neurological disordersand mental illness Existing databases man-aged by NIH or precompetitive consortia couldbe reinforced with donated pharmacokineticdata sets and tutorials

Industry and government scientists shouldwork precompetitively to collect and curatepharmacokinetic data sets in conjunction withsupporting educational materials Mouse phar-macokinetic data exist inside pharmaceuti-cal companies for a wide range of publicallydisclosed molecules and literature standardsRelease of these data into a public databasewould provide several benefits to companiesincluding (i) increased scientific rigor in theliterature with a higher probability of repro-ducibility (ii) increased appreciation by theacademic biology community for the diffi-culty inherent in generating molecules withpotency and pharmacokinetic profiles suit-able for in vivo work opening the door forin-kind collaboration with academic groups

and (iii) direct comparison of data collectedin-house to that collected at other compa-nies or institutions to enable better internalquality control Comprehensive pharmaco-kinetic data sets will benefit all therapeuticareas regardless of whether the brain is thetarget organ because peripheral and cen-tral exposure data can be generated fromthe same experiments Moreover the prin-ciples described above for the CNS apply toother target tissues in which vascular bar-riers metabolic processes or active transportalter the distribution of systemically admin-istered drugs

Key to ensuring that preclinical mousestudies test the hypotheses they aim to eval-uate is an understanding of the unboundfraction of drug present in the target organat an appropriate time point under studyGrant and journal reviewers need to care-fully consider whether authors of propos-als and manuscripts are providing adequaterationale for their choices of preclinical dos-ing paradigms Importantly the collectionand centralization of rodent pharmacoki-netic datasets will promote efficient genera-tion of future data reduce the collection ofredundant data and improve the return oninvestment for research funds that are de-voted to preclinical studies aimed towardclinical translation

Clinical Trials Glossary

ADME an acronym for absorption distribution metabolism and elimination ADME

studies determine how a drug is absorbed by the body the chemical changes that it may

undergo and how it is eliminated from the body

Adverse event (AE) a bothersome event that occurs in a study participant AEs may be

related to the treatment being tested or may be due another cause (eg another treatment

another medical condition an accident or a surgery)

Arm a specific type of treatment to which a group of clinical trial participants is

assigned Some clinical trials have one arm and some have two arms while others have

three or more arms For example a clinical trial comparing two different doses of an

investigational drug versus a placebo would have three arms participants receiving a

higher dose of the investigational drug participants receiving a lower dose of the

investigational drug and participants receiving the placebo

Baseline a point in time at the beginning of a clinical trial before the study participants

receive any treatment At the baseline participants usually have certain types of tests

During and after treatment the same tests may be performed and the results compared

with the baseline results to see if the drug has caused changes

Bias a factor ndash such as a preconceived idea about the effects of the benefits and risks of a

treatment or a lack of balance in selection of patients for a study ndash that reduces the

likelihood that the study results are true Methods such as blinding and randomization

are used to limit the potential for bias

Bioavailability the portion of the dose of a drug that reaches the bloodstream For

example if the drug is administered intravenously its bioavailability is 100 percent

however if the drug is administered in any other way such as orally topically or

through intramuscular injection its bioavailability will decrease due to incomplete

absorption

Bioequivalence study a test performed to compare the portion of a drug in the

bloodstream when administered in different dosage forms

Biologic product any substance that can be used in prevention treatment or cure of

disease Some examples include vaccines blood virus toxin antitoxin and therapeutic

serum

Biopsy the removal of cells or tissue from a patient for examination which is usually

done under a microscope A tissue sample might be taken for genetic studies Sometimes

there is a difference between the blood genotype and the skin or other tissue genotype

This term can also refer to the tissue sample that has been obtained by such a procedure

2

Blinding a process used to prevent the participants the researchers or both from

knowing what specific treatment is being given to participants in a clinical trial The

process of blinding helps to reduce bias because study participants and researchers are

less likely to be unconsciously influenced by the knowledge of what the study participant

is actually receiving If only the participants are blinded the study is called a single-

blind study If both participants and researchers are blinded the study is called a double-

blind study

Carcinogenicity studies long-term studies conducted in animal models to determine a

drugrsquos likelihood of causing cancer

Clinical efficacy a compoundrsquos ability to produce the desired effect

Clinical pharmacology a science that studies properties of drugs in relation to their

therapeutic value in humans

Clinical study or Clinical trial a medical experiment in human beings that helps to

determine how a disease drug or medical device affects study participants Clinical

studies are necessary to answer specific questions about how to better diagnose prevent

or treat a disease or condition

Cohort a group of study participants who have certain characteristics in common such

as female sex a defined age range or particular severity of disease Dividing study

participants into cohorts is often done as part of the analyses of study data

Contraindication a factor that makes the use of a particular drug inadvisable For

example a person who has had an allergic reaction to penicillin in the past is considered

to have a contraindication to using penicillin in the future

Control group a group of participants not receiving the investigational drug but instead

receiving a standard treatment for their disease or receiving a placebo The results

observed in the group of patients receiving the investigational drug are compared with the

results observed in the control group

Crossover study a study design with two or more arms where participants receive one

treatment for a period of time and then switch over to a second treatment for a period of

time Such a study design allows the effects of the two treatments to be compared in the

same patient

Data Monitoring Committee (DMC) or Data Safety and Monitoring Board (DSMB)

A committee of experts that periodically reviews the accumulating data from an ongoing

multicenter clinical trial Members of a DMCDSMB must be independent ie they

cannot be participating as investigators in the clinical trial Based on their review the

DMCDSMB experts advise the sponsor regarding whether it is safe and acceptable to

continue with the study or whether the data suggest that the study should be modified or

stopped A DMCDSMB may recommend that a trial be stopped if there are safety

concerns or if the trial objectives have been achieved

3

Dose-ranging study a clinical trial in which two or more doses of an investigational

drug are tested to determine which dose is likely to offer the best combination of safety

and efficacy in later clinical trials or in medical care

Efficacy or effectiveness the ability of a drug to prevent cure or slow a disease process or to alleviate the symptoms of a disease or condition

Eligibility a determination made during the screening period for a clinical study of

whether a personrsquos participation in the trial is likely to be safe and can contribute data

that will help achieve the study goals

Endpoint occurrence of a disease symptom sign or test result that constitutes one of the

target outcomes of a clinical trial

Inclusionexclusion criteria the factors defined in the protocol of a study that determine

whether a personrsquos participation in a clinical trial is likely to be safe and can contribute

data that will help achieve the study goals Study candidates undergo evaluation during

the study screening period to determine if they meet all of the inclusion criteria and do

not meet any of the exclusion criteria as defined in the protocol These criteria usually

consider such factors as age sex type of disease stage of disease previous treatment

history and other medical conditions in determining eligibility for the study

Informed consent (assent) a process by which medical researchers provide necessary

information to a person about a clinical study and the person voluntarily confirms his or

her willingness to participate in the study Children who are considered old enough to

have a basic understanding of the study may need to provide assent to be involved in the

study a parent or legal guardian must also give informed consent for such a child to

participate

Informed consent (assent) form a document that describes a clinical study to the

participants (or their parentsguardians) The informed consent (assent) form includes

information about the goals of the study the study design and duration the types of tests

to be performed the potential risks and inconveniences the potential benefits the

possible costs or payments associated with study participation the available alternative

therapies the rights and responsibilities of the participant and the people to contact if the

participant has questions The informed consent (assent) form must be reviewed and

signed before the participant has any study tests or treatment including the tests

performed during the screening period at the beginning of the study Participants are

given a copy of the informed consent (assent) form to take home

Institutional Review Board (IRB) or Independent Ethics Committee (IEC) a board

of physicians statisticians researchers community advocates and others who are

responsible for ensuring the protection of the rights safety and well-being of participants

in a clinical trial at a study center This board is called an IRB in the United States and is

often called an IEC in other countries IRBIECs review and approve important study

documents (eg protocols informed consent forms study advertisements and patient

4

brochures) before the start of the study and periodically review the progress of the study

while it is ongoing

Investigational Drug a drug that is being tested as a potential treatment for a disease or

condition but has not yet been proven safe and effective for that use

Investigator a physician or other health care worker who carries out a clinical trial by enrolling treating and monitoring participants and recording the results

In vitro testing testing conducted in test tubes or other artificial environments

In vivo testing testing conducted in living animals or humans

Longitudinal study a clinical study that involves observations of the same items over

long periods often many decades Because longitudinal studies track the same people

they are often used to study trends across the life span to uncover predictors of certain

diseases or to track the effects of a particular treatment on a patientrsquos condition over

time

Multicenter study a study conducted at more than one location Multicenter clinical

studies are generally performed when each individual clinical trial site does not have

enough study candidates to complete a large trial

Natural history study a study of the natural development of a disease or condition over

a period of time Natural history studies are usually longitudinal studies

New Drug Application (NDA) the registration document through which a

pharmaceutical company formally proposes that the FDA approve a new drug for

manufacturing and sale The application includes detailed reports of pharmacology

toxicology manufacturing and chemistry as well as data from clinical trials

Open-label study a study in which the participants and the investigators know which

treatment is being given In an open-label study there is no blinding and none of the participants receives a placebo

Orphan disease a disease or condition that affects a relatively small number of people

In the US this defined as fewer than 200000 people In Europe this is defined as fewer

than five in 110000 people

Orphan drug a drug intended to treat an orphan disease

Participant or subject a patient or healthy volunteer who participates in a clinical trial

Phase 1 the initial phase of testing of an investigational drug in humans Usually a

Phase 1 clinical study is conducted in a small number of healthy volunteers or patients

with a disease for which the drug may be useful Generally the study is designed to

determine the side effects of the drug and its pharmacokinetics Some information

5

regarding drug efficacy may be collected if patients with a disease participate A phase

frequently encompasses more than one clinical trial Phase 1 sometimes is sub-divided

into Phases 1a and 1b for example when the first set of Phase 1 trials (Phase 1a) is

performed in healthy volunteers and a second set of Phase 1 trials (Phase 1b) is

performed in patients with a disease

Phase 2 the intermediate phase of testing of an investigational drug in humans Usually

a Phase 2 clinical study conducted in patients with a disease for which the drug may be

useful Generally the study is designed to evaluate dosing to obtain preliminary data on

the effectiveness of the drug and to acquire more safety information Phase 2 sometimes

is sub-divided into Phases 2a and 2b Phase 2a studies typically are smaller and shorter

in duration and evaluate different drug doses to see how they affect certain tests that can

indicate whether the drug is working as expected Phase 2b studies typically enroll more

patients are of longer duration and evaluate whether the drug is offering clinical benefits to patients Phase 2b studies sometimes are considered pivotal or registration-directed

Phase 3 the final phase of testing an investigational drug in humans before regulatory

approval Phase 3 studies are usually conducted in a large population of patients and are

generally designed to confirm the effectiveness of the drug and to evaluate the overall

risk-benefit ratio Phase 3 studies usually test the investigational drug in comparison with

a standard treatment for the disease or a placebo

Phase 4 testing of a drug in humans after it has already been approved by regulatory

authorities and can be used in medical practice Phase 4 studies may be conducted to

compare the drug to a similar type of drug to explore whether it may help patients with

other diseases to further study the long-term safety of the drug or for other reasons

Pivotal study a study that is designed to generate the data required by regulatory

authorities to decide whether to approve an investigational drug A pivotal study is

usually a large randomized Phase 2b or Phase 3 study and often is blinded and uses a

placebo as a control Sometimes a pivotal study is described as a registration-directed

study

Placebo an inactive version of an investigational drug A placebo has a similar

appearance to the investigational drug but is expected to have no therapeutic value A

placebo is used as a comparison treatment to reduce bias in randomized studies

Preapproval access program an umbrella term for programs that allow seriously ill

patients to receive an investigational drug when they are unable to participate in clinical

trials and there is no alternative treatment This is sometimes referred to as

compassionate use Types of pre-approval access programs include expanded access

parallel-track named patient program single-patient exemption and treatment IND The

timing for starting an expanded access program usually depends upon what is known

about the risk-benefit of the drug and whether the drug can be provided in a manner that

is fair to patients with the disease

6

Preclinical (nonclinical) testing testing of a drug in test tubes or in animals A drug

undergoes preclinical testing before being tested in humans to make sure that it shows

evidence of desired effects and is sufficiently safe for study in people Preclinical testing

sometimes also helps to determine the doses of the drug that should be evaluated in

humans Preclinical testing is sometimes called nonclinical testing

Protocol a document describing what types of people may participate in a clinical study

and the objectives treatments measurements statistical methods timing and

organization of a clinical trial The protocol must be prepared in advance of the study

and must be reviewed and approved by review committees and regulatory authorities

before the study is started Investigators must follow the protocol to carry out the study

Randomization assignment of participants to treatment arms based on chance This is

usually done by a computer program in a way that does not allow either the participants

or the investigators to choose who is assigned to which arm Randomization is used to

reduce bias in clinical trials

Risk-benefit ratio the balance of the risk of side effects expected with use of a drug

versus the potential for benefit with the use of that drug A drug with a good risk-benefit

ratio has few side effects and is very effective

Serious adverse event (SAE) an adverse event that is life-threatening requires inpatient

hospitalization or lengthens a hospital stay leads to substantial disability leads to a birth

defect or results in death

Side effect any effect of a drug other than the desired effect Side effects are often

unwanted and may be bothersome Other names for a bothersome side effect are adverse

drug reaction (ADR) or drug toxicity

Screening period a period at the beginning of a clinical trial when candidates for the

study are evaluated to determine if their participation is likely to be safe and can

contribute data that will help achieve the study goals

Significant or statistically significant an outcome in a clinical trial is likely to result

from a real difference (eg due to an effect of a treatment) and is unlikely to be due to

chance alone The level of statistical significance is often expressed in terms of a p-

value which indicates the probability that a difference is not due to chance alone

Usually a p-value smaller 005 is considered statistically significant

Sponsor the organization responsible for financing and coordinating a clinical trial

Most often this is a pharmaceutical or biotechnology company

Standard treatment a treatment currently in wide use often approved by regulatory

agencies and generally considered effective in the treatment of a specific disease or

condition

7

Toxicity a side effect produced by a drug that is bothersome to the person taking the

drug

Toxicology the study of the adverse effects of chemicals conducted in animal models to

predict potential adverse effects in humans Some studies are conducted during clinical

development to evaluate dosing regimens

CLINICAL RESEARCH MAP

Boston Childrenrsquos Hospital Clinical Research Map 2 Mouse over for additional info Bold = hyperlink

ObjectiveThis clinical research map is designed to serve as a guide for investigators study coordinators and research nurses at Boston Childrenrsquos Hospital The research map outlines the key steps in preparing to launch a research study and provides embedded links to institutional resources tools and documents

An investigator need not follow the steps on the Clinical Research Map in any particular order There is flexibility and the steps followed will in part de-pend on the type of research study

For new as well as more experienced investigators the Clinical Research Map can be used as a checklist or an inves-tigator can use the steps on the map as points for consideration as they are developing a protocol and launching a study

This tool is not intended to substitute for the important collaboration be-tween a junior investigator and a senior investigatormentor A senior investiga-tor plays a pivotal role in coaching and advising a junior investigator regarding the many subtleties and variations that apply to designing and implementing a protocol

This process map cannot be inclusive of every possible task or step but is intended as a general guide for investi-gators and their study teams

ResourcesThere are many institutional resources at Boston Childrenrsquos Hospital designed to support investigators and their clini-cal research teams In addition to links to resources tools and documents that are embedded in the steps of the clini-cal research map the last page of this document contains website addresses that will take you to additional helpful institutional resources
