Aaron Almeida Senior Scientist II, Arrowhead Pharmaceuticals
ABSTRACT A primary challenge in the development of RNAi therapeutics is delivering the RNAi trigger molecules
into the cytoplasm of the cell where RNAi activity occurs. Dynamic PolyConjugates (DPC’s) are
Arrowhead’s innovative delivery system engineered specifically to induce efficient endosomal
escape. The endosomal release is facilitated by a peptide that is reversibly-masked for reduced non-
specific interactions during in vivo circulation, and is actively targeted to the desired cell type through
efficient receptor binding. Here we present an example of the DPC platform composed of a hepatocyte-
targeted endosome-releasing agent and a cholesterol-conjugated siRNA. This delivery platform forms
the basis of ARC-520, an siRNA-based therapeutic for the treatment of chronic hepatitis B virus (HBV)
infection. DPC’s have demonstrated rapid, deep and durable knockdown of target genes expressed
in the liver and has been well tolerated in clinical trials.
Yvonne Angell Scientific Consultant, Cogentis Therapeutics
ABSTRACT Cogentis is a pre-clinical stage biotechnology company dedicated to developing therapies that target the
dysregulated cyclin-dependent kinase 5 (CDK5) molecular pathway. Because clinical trials for
Alzheimer’s disease (AD) are costly and slow, Cogentis will focus initially on frontotemporal dementia
(FTD), a rare disorder that is an early-onset, rapidly-progressive neurodegenerative condition leading to
death within five years. FTD and AD are thought to be tauopathies, diseases characterized by toxic
accumulations of a normal protein called ‘tau’ in the brain. There are currently no approved drugs
to treat any of the tauopathies. In brains from FTD patients CDK5 over-phosphorylates tau, leading to
the toxic accumulation of tau. Post-mortem brains from AD and FTD patients were shown to have
elevated CDK5 activity. Previous efforts to inhibit CDK5 have proven too toxic due to lack of specificity.
Cogentis has exclusive rights to CT-526, a novel peptide which was invented at the NIH and is an
allosteric CDK5 inhibitor. CT-526 penetrates the blood-brain barrier and engages CDK5 away from the
active site, preventing aberrant activity while preserving normal function, showing zero signs of toxicity
at > 100x the effective dose. Preclinical success in multiple mouse models of AD, Parkinson’s disease
(PD), and amyotrophic lateral sclerosis (ALS) supports expansion/development to multiple diseases. In
advanced AD mice, it reversed tau phosphorylation, amyloid beta plaques (Ab), motor instability and
cognitive deficits to normal.
BIO For the past 20 years my career has focused on the discovery and development of new peptide

ABSTRACT Small proteins composed entirely of D-amino acids enhance the advantages of small proteins, such as
high tissue and tumor penetration rates, smaller dose volumes, and multi-specific formats, by enabling
greater stability, longer half lives and reduced immunogenicity. Chemical protein synthesis combined
with mirror image phage display has been used to produce potent inhibitors of VEGF-A and other
therapeutic targets. The role of stereochemistry in immune responses and recent progress in the
development of D-amino acid proteins as therapeutics will be presented.

ABSTRACT p28 is a cell-penetrating peptide that crosses the blood brain barrier, preferentially enters cancer cells
and binds to both wild-type and mutant p53 protein, inhibiting COP1-mediated ubiquitination. The
decrease in ubiquitination results in increased levels of p53 and induction of cell cycle arrest at G2/M.
Patients aged 3–19 years with recurrent or progressive central nervous system tumors received p28 at
the adult recommended phase 2 dose. Seven of 12 evaluable participants received ≥ 2 cycles (12
weeks) of p28 with the most common adverse event attributed to the drug a transient grade 1 infusion-
related reaction. PK analysis revealed a profile similar to adults. Three (of 12; 25%) participants
remained stable disease (SD) on the study; two for > 5 cycles (30 weeks) demonstrating that p28 is well-
tolerated in children with recurrent CNS malignancies at the adult recommended phase 2 dose.

ABSTRACT RiPPs are a rapidly growing class of peptide derived natural products. RiPP enzymes carry out
remarkable chemistry en route to transforming short peptides into bioactive molecules. We have
recently developed new technology for generating large and diverse libraries of RiPP natural products
based on the promiscuity of key biosynthetic enzymes from RiPP pathways. Two examples will be
presented. First, by employing members of the new pyridine synthase family of macrocyclases,
discovered in our lab, we create non-natural analogues of the potent anti-MRSA antibiotics known as
thiopeptides to explore their structure activity relationships. Second, we exploit the sactionine synthase
AlbA from Bacillus subtilis to design stapled alpha-helical mimics for the inhibition of key therapeutic
targets.
BIO Born and raised in New Jersey, Dr. Bowers obtained his BA from the University of Chicago and went on
to complete his Ph.D. in organic chemistry in 2007, at the University of Illinois at Chicago, under the
guidance of Prof. David Crich. He was an NIH postdoctoral fellow in the labs of Professor Robert M.
Williams at Colorado State University and Professor Christopher T. Walsh at Harvard Medical School.

ABSTRACT A significant challenge in the development of effective antibacterial agents arises from bacterial
pathogens that have evolved to inhabit mammalian cells, such as phagocytic macrophages. Within these
intracellular safe havens the bacteria reproduce and form a repository, and are able to evade the host
immune response as well as a number of antibiotic drugs. Therefore, there is a great need to develop
antibiotics with the ability to enter mammalian cells and target intracellular pathogens at their specific
sub-cellular site. We have developed a class of molecules, cationic amphiphilic polyproline helices
(CAPHs), that enter mammalian cells through both direct transport and endocytosis. We have
determined that CAPHs also have potent antibacterial activity in vitro with a non-lytic mechanism of
action. This dual mode of action, non-lytic antibacterial activity with the ability to localize within
mammalian cells, provided us with agents with a pronounced ability to target and kill pathogenic
intracellular bacteria, including Mycobacterium tuberculosis, within human macrophages.
Danny Chou Assistant Professor, University of Utah
ABSTRACT For people with diabetes, maintaining blood glucose levels within the nondiabetic range is effective in
delaying or even preventing long-term complications, but achieving near normoglycemia is still
challenging for these patients. The current fast-acting insulin still has relatively slow absorption after
subcutaneous injection which leads to delayed insulin response and sub-optimal control of glycemia.
Furthermore, the long duration of action (4-5 hours) may lead to post-meal hypoglycemia. Innovation in
insulin design has been hampered by the hexameric status of insulin; an ultrafast-acting insulin requires
a monomeric insulin molecule. Therefore, despite millions of dollars invested, a truly monomeric,
ultrafast-acting insulin remains to be invented. In this presentation, I will discuss our bio-inspired
approach to utilize a venom insulin as a potential candidate with ultrafast-acting properties.

ABSTRACT Non-natural cyclic peptides constitute an underutilized yet attractive segment of the chemical diversity
space. Such peptides are conformationally, chemically and proteolytically stable, the incorporation of
non-proteinogenic amino acids generally lowers their immunogenicity, their binding interfaces can be of
the size and complexity not achievable in small molecules, and all these desirable properties materialize
in relatively short sequences that can be readily synthesized using the routine solid phase methodology.
Such artificial peptides cannot be, by definition, derived from natural sequences. Combinatorial
chemistry faces substantial difficulties in this case due to the combinatorial complexity involved. De
novo design is thus the preferred enabling technology for this class of molecular entities. An original
variant of the Monte Carlo chain growth algorithm was applied to the design of short cyclic peptides -
CD4-mimicking ligands of HIV gp120. In the role of entry inhibitors, the engineered cyclic peptides
performed by 1 to 2 orders of magnitude better than the mechanistically similar small molecule positive
standard NBD-556. Conclusion: Structure-based de novo design is capable of delivering cyclic peptides
that fill the gap between small molecules and biologics. The case study indicates a satisfactory capability
of these synthetic compounds to mimic biologics, while offering much better drug-like properties.
Jesse Z. Dong Vice President, Peptide Chemistry, Neon Therapeutics
ABSTRACT Neon Therapeutics is pursuing an exciting clinical development program of a personalized neoantigen
vaccine. Neoantigens arise as a result of somatic mutations during the development and progression of
tumors. They are inherently non-self and are seen as foreign by the immune system. Mounting evidence
suggests that immune rejection of tumors, for example which is seen with checkpoint modulators, may
be mediated by recognition of neoantigens. Neon’s peptide vaccine targets neoantigens unlocking
the immune system to attack tumors.

ABSTRACT The novel apoE4 therapeutic CS6253 penetrates the blood brain barrier, upregulates the ABCA1
transporter and prevents Alzheimer’s disease pathogenesis Anat Boehm-Cagan1, Jan O. Johansson2,
John K. Bielicki3 and Daniel M. Michaelson11The Sagol School of Neuroscience, Tel Aviv University,
Israel; 2Artery Therapeutics, Inc.; 3Lawrence Berkeley Laboratory, USBackground: The allele ε4 of
apolipoprotein E (apoE4) is the most prevalent genetic risk factor for Alzheimer's disease (AD). No apoE4
specific therapeutic is presently available. ApoE is the natural ligand to the ABCA1 transporter, both
proteins found predominantly in astrocytes. The apoE to ABCA1 interaction regulate lipidation of apoE
and lipid composition of astrocyte cell membranes with many potentially favorable down-stream effects
of relevance for brain pathophysiology. We hypothesized that manipulating the apoE4 to ABCA1
interaction would have AD therapeutic actions. To this purpose we applied a peptide that selectively
causes ABCA1 mediated lipid removal from macrophage cells in established apoE4 vs. E3 in vitro and in
vivo models. Methods and results: Astrocyte cholesterol efflux is highly responsive to stimulation by
exogenous CS6253 peptide. Humanized astrocytes from apoE3 (E3) or apoE4 (E4) targeted replacement
mice were labeled for 2 days with [3H]cholesterol (1 mCi/mlL), and treated overnight with 22-
hydroxycholesterol/cis retinoic acid (each 10 mM final concentration) to upregulate ABCA1 expression.
Time-course showed basal [3H]cholesterol efflux from cells to serum-free medium was compromised in
apoE4 astrocytes. Incubating with peptide CS6253 (10 µg/mL) showed 6-fold improvement in
[3H]cholesterol efflux to serum-free medium containing in both apoE4 and E3 astrocytes. CS6253 i.p.
injection (20 mg/kg/48h for 6 weeks) in apoE4 target replacement mice prevented AD phenotype
pathogenesis and cognition decline. CS6253 crossed the BBB providing brain levels higher than the in
vitro EC50-value for ABCA1 mediated cholesterol efflux, and was found to co-localize with astrocytes in
the brain in both apoE3 and E4 mice. Levels of hippocampus ABCA1 were significantly lower in apoE4
mice compared to apoE3 mice in PBS treated groups and significantly increased by CS6253 treatment in
apoE4 mice. Lipidation of apoE in the hippocampus was compromised in apoE4 compared to apoE3
mice. CS6253 treatment increased apoE4 lipidation. Further analysis showed that CS6253 treatment
counteracted the apoE4-driven phenotype in the hippocampus resulting in decreased Aβ42 and
phosphorylated tau and increased levels of VGluT1 and apoER2. Cognitive decline was fully prevented in
apoE4 mice by CS6253 treatment as assessed by novel object recognition and Morris water maze.
Conclusion: ABCA1 agonist treatment by CS653 resulted in improved apoE4 lipidation in cells and in
mice. Six weeks treatment consistently counteracted apoE4 driven AD with regard to both phenotype
and cognition. The data point to the potential therapeutic utility of CS6253 in apoE4 sporadic AD.

ABSTRACT Following the successful development of the first once-daily GLP-1 analog liraglutide we aimed to
discover analogs suitable for once-weekly dosing through acylation with fatty acids, enabling binding to
serum albumin in vivo. This technology allows a drug molecule that is structurally near human GLP-1,
which is not possible with fusion protein strategies. To go from once-daily to once-weekly dosing, the
aim of our studies were to increase albumin affinity and obtain full stability against DPP-4 degradation,
without compromising a high GLP-1 receptor (GLP-1R) affinity. The human GLP-1R was used for testing
of receptor and albumin affinity. Pharmacokinetic properties were investigated in rats and pigs.
Alterations in the peptide sequence as well as the fatty acid “sidechain― were explored. The latter
was the key feature to secure the combination of high albumin affinity and high GLP-1R potency. Length
and type of fatty acid as well as the linking chemistry between the fatty acid and GLP-1 were the
parameters investigated. Semaglutide was selected as the optimal once weekly candidate. Semaglutide
has two amino acid substitutions compared to human GLP-1 (Aib(8), Arg(34)) and is derivatized at lysine
26. The GLP-1R affinity of semaglutide (0.38 ± 0.06 nM) was three-fold decreased compared to
liraglutide, whereas the albumin affinity was increased. The plasma half-life was 46.1 h in mini-pigs
following i.v. administration, and semaglutide has an MRT of 63.6 h after s.c. dosing to mini-pigs.
Semaglutide is currently in phase 3 clinical testing.

ABSTRACT The challenges involved in the chemical synthesis of insulin and its analogs hinder the exploration of the
structure-function relationships of this indispensable therapeutic. Problematic features such as the
hydrophobicity of the A-chain and the complexity of the disulfide architecture are unique to insulin and
have required implementation of specialized strategies. Our efforts have centered on two fundamental
approaches: the single chain biomimetic route and the two-chain directed disulfide method. An example
of the former is our use a novel single chain precursor “desDi― which enabled superior folding
efficiency and proved to be less sensitive to individual substitutions. The latter approach is exemplified
by the directed disulfide approach using orthogonally protected cysteine pairs to form insulin. We have
additionally expanded the scope of the two-chain directed disulfide method to other insulin like
peptides which contain oxidation-sensitive residues through the use of an iodine-free method
employing Phacm cysteine protection and enzymatic conversion to form the (A7-B7) disulfide bond. We
will also highlight application of the isoacyl concept to address the hydrophobicity of the A-chain and
preparative recovery of both chains. Application of the isoacyl route afforded human insulin in 24%
overall yield based on initial resin substitution representing the most efficient chemical synthesis of
human insulin to date.
Len Luyt Associate Professor, University of Western Ontario
ABSTRACT The interaction of the polysaccharide hyaluronan (HA) with RHAMM (receptor for hyaluronan mediated
motility) is implicated in the promotion of inflammatory responses. RHAMM is an intracellular tubulin-
binding protein that, in response to injury, is exported to the cell surface, associates with CD44 and,
upon binding to HA, results in activation of growth factor signalling pathways, including ERK1,2.
Interfering with RHAMM-HA interactions has therapeutic potential for inflammation-related diseases
including arthritis, chronic fibrosis and cancer. We have discovered peptides that interfere with
RHAMM-HA binding. In one approach, peptides that bind to RHAMM were developed based upon
sequences of the carboxy-terminal tail region of tubulins that bind to the RHAMM HA binding region.
These peptides act as mimics of HA and it has been shown that they have selectivity for RHAMM over
other HA receptors such as CD44. In another approach, stapled peptides consisting solely of the HA
binding domain of RHAMM were discovered to maintain the alpha-helical character of RHAMM and bind
to HA. The evaluation of these peptides for their effect on cell migration/invasion, inflammation and
fibrosis, will be discussed. The ability to discover peptides that interfere in RHAMM-HA interactions sets
a precedent for a new approach in the development of drugs that target protein-carbohydrate
interactions.

ABSTRACT Peptides possess enormous potential to contribute to the current standard of care across many
therapeutic areas. By virtue of their inherently short plasma residence time, it is advantageous to
identify robust strategies to extend their time-of-action in circulation to lessen the burden of frequent
injections. GIP/GLP-1-based dual agonists represent a novel approach to treat diabetes, but such
peptides still require protraction in circulation to reduce the burden of frequent injections. In this study,
a GIP/GLP-1-based dual-agonist peptide was derivatized with iodoacetamide and conjugated to thiol-
bearing time-extension moieties. Four different time-extension technologies were evaluated and
compared: native human albumin, XTEN (3 sizes), heparosan (3 sizes), and hydroxyl ethyl starch (3 sizes).
The presentation will discuss the in vitro activity of the peptide analogs against the GLP1-R and GIP-R, as
well as their pharmacokinetic and pharmacodynamic characteristics in preclinical in vivo models.

ABSTRACT Peptides with high affinity and selectivity for the kappa opioid receptor have been known for more than
20 years, but peptides suitable for clinical development have not been forthcoming. CR845 is a potent
and selective synthetic peptide kappa opioid receptor (KOR) agonist being developed as both
intravenous (IV) and oral formulations (enteric-coated tablets). CR845 is currently in mid- to late stage
clinical development (Phase 2-3) to assess the safety and efficacy of this drug in patients with post-
operative pain, osteoarthritis or uremic pruritus using the IV or oral formulation depending upon the
particular indication. CR845 has full agonist activity at rodent and human kappa opioid receptors (EC50 =
0.16 nM) with no other detectable off-target activities. Non-clinical pharmacological studies indicate
that CR845 has combined analgesic, antipruritic, and anti-inflammatory properties which support the
therapeutic indications of pain and pruritus being pursued with this compound. CR845 is composed of 5
unnatural amino acids and does not readily cross the blood-brain barrier. Consequently, CR845
predominantly activates KORs expressed in peripheral neurons and on immune cells. CR845 is primarily
excreted unchanged into the urine and bile with no major metabolites identified. The safety data
available to-date and the potential benefit of CR845 treatment support continued study and
development of this compound.
BIO I have been with Cara Therapeutics for 9 years primarily focused on the GMP manufacturing of CR845
drug substance and drug product for the clinical development program. Prior to Cara, I was at Bayer (in
West Haven, CT) for 8 years working in both the research (Medicinal Chemistry) and Development
(Project Management). I began my professional career with Abbott Laboratories as a Medicinal Chemist
in 1993.

ABSTRACT Impaired immunity as a consequence of chemotherapy, infection or malignancy leads to a reduced
antimicrobial peptide (AMP) host immune response. This is because of the depletion (in number &
functionality) of the sources of these key immune effector molecules; neutrophils & epithelial cells.
Patients in this immunocompromised state are consequently susceptible & often succumb to fungal
infections from organisms such as Aspergillus Spp, Candida Spp & Cryptococcus Spp which a functioning
AMP system would normally keep in check. Increasing infection & mortality rates from fungal infections
drive an urgent need for new antifungal solutions to these poorly served clinical challenges. NovaBiotics
has engineered Novamycin, a novel, arginine-based AMP to target these infections as a more potent
"replacement" of naturally occurring AMP. As a membrane-acting, rapidly fungicidal agent, Novamycin
has multiple benefits & USPs over the existing, limited armoury of ineffective &/or toxic hydrophobic
small molecule antifungals; not least its lack of toxicity, resistance development, more rapid time of kill
& broader spectrum of antifungal activity. NovaBiotics has demonstrated that as a hydrophilic peptide,
Novamycin has the physicochemical benefit over existing therapeutic options of being able to be
successfully formulated & delivered by inhalation, parenterally & mucocutaneously to effectively target
at least Aspergillus Spp & Candida Spp in the respiratory tract, blood stream/deep tissues & in the oral &
vaginal cavities. Novamycin is highly differentiated as a much needed antifungal therapeutic candidate
& on the basis of the in positive in vitro and in vivo efficacy & toxicology data sets obtained thus far, will
progress quickly into clinical development as an inhaled therapy in pulmonary Aspergillosis in the first
instance.

ABSTRACT Therapeutic peptides and proteins are not effective when they are not able to reach their targeted
tissues and remain there long enough for activity. In particular, therapies for diseases of the joint cannot
penetrate into avascular tissues such as the articular cartilage and meniscus. ProteoThera solves this
probem with a proprietary matrix-binding peptide that allows for optimal transport into tissues and
extended residence in those tissues while maintaining activity of the therapeutic cargo.

Robin Polt Professor of Chemistry & Biochemistry, BIO5, The University of Arizona
ABSTRACT The incorporation of O-linked glycosides into endogenous neuropeptides provides glycopeptides of
enhanced stability that penetrate the Blood-Brain Barrier (BBB), and retain affinity for their G-Protein
Coupled Receptors (GPCRs). Several examples have been explored to produce analgesic and
neuroprotective CNS drugs with masses ranging from 700—3,500 M.W., including enkephalins,
endorphinsdynorphins, secretins and other potent peptide hormones. We may regard this class of
drugs as one that bridges the gap between "small molecules" and "biologics."
BIO Polt has embraced several relatively diverse scientific disciplines in his career, often running counter to
the prevailing wisdom and advice. He studied chemistry at IUPUI under the direction of Prof. Martin J.
O’Donnell, where he was involved in the enantioselective alkylation of masked glycine anion and
cation equivalents to produce the first of the “O’Donnell Schiff Bases.― (Ph2C=O +
H2NCH2CO2CH2CH3 → Ph2C=NCH2CO2CH2CH3) A NSF Fellowship that took him to Columbia
University where he studied with Prof. Gilbert J. Stork, and then on to Prof. Dieter Seebach’s group in
Zürich where he studied the alkylation of peptides in addition to glycine equivalents. Robin shifted his
interests toward the synthesis and evaluation of glycopeptide drugs at the University of Arizona.
Glycosylated neuropeptides show excellent biological activity, extended stability in vitro and in vivo, and
also cross the blood-brain barrier to produce centrally-mediated effects. Presently, Robin is involved in
the study of glycolipid surfactants in collaboration with Prof. Jeanne Pemberton, as well as Prof. Michael
Heien, who uses MS2 and MS3 techniques coupled with microdialysis to quantify our drugs and their
metabolites in vivo.

Biochemistry and Molecular Biology working in UCL and Cardiff University and has co-authored over 40
peer-reviewed scientific publications. With over 10 years experience in Cell Penetrating Peptide (CPP)
research, he is pioneering the practical use of “Cupid―, the most powerful form of CPP, as a
technology platform for Biomolecular Researchers to understand protein-protein interactions.

ABSTRACT As a drug class, peptides offer exquisite specificity and potency, but also present challenges associated
with poor stability and short half-life, manifesting in the need for frequent injections, poor patient
compliance, and overall compromised efficacy. Exendin-4, a glucagon-like peptide-1 receptor agonist
administered twice daily via subcutaneous injection, improves glycemic control, often with associated
weight reduction. To further improve the therapeutic efficacy of exendin-4, we have developed a novel
peptide engineering strategy that incorporates a serum protein binding motif onto a covalent side-chain
staple and applied to the peptide to enhance its helicity and as a consequence, its potency and serum
half-life. We demonstrated that one of the resulting peptides, E6, has significantly improved half-life and
glucose tolerance in an oral glucose tolerance test (OGTT) in rodents. Chronic treatment of E6
significantly decreased body weight and fasting blood glucose, improved lipid metabolism and also
reduced hepatic steatosis in DIO mice. Moreover, the high potency of E6 allowed us to administer this
peptide using a novel microstructure-based transdermal delivery system. Pharmacokinetic and
pharmacodynamic studies in guinea pigs showed that a single 5 min application of a microstructure
system containing E6 significantly improved glucose tolerance for 96 hours. This delivery strategy may
offer an effective and patient-friendly alternative to currently marketed GLP-1 injectables. Current
progress in applying this half-life extension strategy to other peptide hormones will also be discussed.

ABSTRACT Endometriosis is estimated to affect 5-10% of women of reproductive age and causes infertility in about
50% of cases; affecting over 200 million women and girls globally. Currently, there are over 15 million
surgically confirmed patients of Endometriosis in North America with an overall impact of approximately
$22 Billion dollar on economy. Endometriosis, for which there is no absolute cure, is a painful female
reproductive disease in which tissue from the uterine lining (endometrium) migrates outside the womb
and implants in other areas of the body. Endometrium in ectopic sites must establish its own blood
supply to supports its growth and development into an endometriosis lesion. SYNG Pharma’s novel
target is an intrinsically disordered protein that functions in its physiologically unfolded form, has
elevated expression in endothelial cells of endometriosis lesions compared to eutopic endometrium.
SYNG Pharma has developed a specific peptide inhibitor, SP011, a potential first non-hormonal therapy
of endometriosis. In vitro binding studies demonstrate that SP011 specifically binds to the target.
Localization of SP011-FITC was shown using intra-vital fluorescence microscopy, which also confirmed
inhibition of neovascularization in presence of peptide inhibitor using an animal model of endometriosis.
Data from pre-clinical efficacy studies using animal model shows inhibition of human endometrial lesion
growth and reduction of neovascularization. Treated group also had reduced blood vessel growth when
given daily intraperitoneal injections of SP011 compared to phosphate buffered saline control.

ABSTRACT The maintenance of glycemic control is most conveniently achieved using insulin pumps which require
an insulin formulation that is stable for extended periods of time at body temperature. Current insulin
formulations are only stable for days before chemical degradation and/or fibrillation results in loss of
activity and the potential for clogging of insulin pumps. We have demonstrated the use of Cap-ClipTM
technology for the rapid SAR discovery of conformation locked ultra-stable and ultra-concentrated
insulins. Novel insulin analogues with both long acting and short acting profiles were discovered that are
stable at 40â•°C for more than 3 months and can be concentrated to U1000 and greater. I will provide a
summary of the discovery program and a preliminary SAR tree relating design principles to activity and
stability.

ABSTRACT The complement system is part of the body’s immune system. It can be activated by three principal
activation pathways: the classical pathway, the lectin pathway and the alternative pathway. All three
activation pathways converge on C3, leading to three principal effects of complement activation:
opsonization, inflammation and the membrane attack complex formation. Under conditions of excessive
or uncontrolled activation, the complement system plays a key role in a wide range of autoimmune and
inflammatory diseases. Apellis lead product candidate, APL-2, targets the complement system at the C3
level, inhibiting all effects of the complement cascade. By inhibiting C3, we believe that APL-2 may effect
disease control and disease modification.
APL-2 is the conjugate of APL-1, a synthetic cyclic peptide, with a long half-life. It is currently in the clinic
for the treatment of PNH and AMD. Recent data from healthy volunteer studies confirmed that
pharmacological doses of APL-2 were safe and well tolerated and that APL-2’s PK/PD profile supports
daily SC administration. In addition, daily APL-2 doses of 180 mg and 270 mg significantly reduced
hemolytic activity as early as eight days after the start of dosing, and this inhibition was maintained
through the dosing period.
