Essential Elements for a National CancerClinical Trials Network – Basis for Collaboration
ICTW Punta del Este, Uruguay
Group Collaborations – Opportunities – Types of Trials
• Studies whereby an efficient process is required
• Large RCT’s• Strategic Phase II trials• Uncommon diseases or less common presentations of
common diseases
• Integrate new agents into standard regimens
• Compare two or more approaches to an accepted standard
• Multimodality treatments• Translational studies. Incorporate
correlative science and quality of life• “Pooled” resources• Tissue banking
ICTW Punta del Este, Uruguay
• Enrollment often is not representative of the general population Factors affecting enrollment are multiple and complex
• Well designed controlled trials are necessary to identify sometimes small benefits • Important time and human and infrastructure resources are invested in the conception, launching, and execution of a clinical trial. AVOID DUPLICATION IS CRITICAL
• Timely completion of trials is key
• Well developed regional, national, and international networks and collaborations are important to obtain definitive results to advance cancer research and patient management
Challenges in Clinical Trial Research
ICTW Punta del Este, Uruguay
Challenges for Coordinated Efforts
• Standardizations of definitions for efficacy endpoints
• Harmonized Data Elements– Identify and standardize translational research data elements
to be commonly collected across trials
• Specimen collection SOPs
• Data Sharing System– Share electronic data files to allow for the study of specific
questions across trials– Create a system that provides a data mining capability that
should allow more contemporaneous and frequent analysis of pooled resources from contributing groups
• Publication guidelines
ICTW Punta del Este, Uruguay
Hurdles to International Collaboration1. Scientific agreement on clinical study design
• Close communication and interaction essential
2. U.S. requirement for international institutions to obtain Federal Wide Assurance (FWA)
• If receiving U.S. funds or exchanging patient data
3. Technical agreement on data collection and submission
4. Requirements for auditing of collaborating international institutions
5. Tissue banking – Analysis
6. Drug distribution across borders and other regulatory issues
ICTW Punta del Este, Uruguay
International Regulatory Issues• Harmonization of clinical practice across all
sites• Registration of investigators• National and local regulatory approval• Harmonization of data collection• Reporting of adverse events• Insurance requirements• Global variation in regulations
ICTW Punta del Este, Uruguay
International Committee of Harmonization (ICH)
It is ICH’s mission to achieve greater harmonization in the interpretation and application of technical guidelines and requirements for product registration, thereby reducing duplication of testing and reporting carried out during the research and development of new medicines.
http://www.ich.org/home.html
ICTW Punta del Este, Uruguay
ICH
• Drug regulatory authorities and pharmaceutical trade associations of Europe, Japan, and the United States discuss scientific and technical aspects of product registration.
• QSEM– Quality– Safety– Efficacy– Multidisciplinary
.
ICTW Punta del Este, Uruguay
Harmonization of clinical practice• Patient eligibility: pathologic diagnosis,
imaging studies, laboratory tests• Surgical treatment• Chemotherapy and biologic treatment• Radiation therapy• Supportive care• Surveillance and follow-up
ICTW Punta del Este, Uruguay
Patient Selection – Lab Assays
• Nowadays in the era of personalized medicine: it is critical that patient selection based on a specific biomarker is done using properly standardized assays– Are we really testing what we want to test?– Are we really categorizing adequately?– EGFR mut, BRAF mut, EML4/ALK, ERCC1, Risk
classifiers
• Standardization and Validation• Important ethical and regulatory implications
ICTW Punta del Este, Uruguay
Registration of investigators & sites• Harmonization of registration
– US FDA 1572 form or equivalent– Copies of curriculum vitae and medical licenses
for physicians
• Financial disclosure forms for physicians• Certification of laboratories for clinical tests• Inspection of study site before trial opens
ICTW Punta del Este, Uruguay
Regulatory approval
• Approval of trial by national trial regulatory agency (equivalent of US Food and Drug Administration)
• Approval by independent ethics committee– National, regional, or local
• In some cases, approval by scientific review committee
• Documentation of approvals required
ICTW Punta del Este, Uruguay
Harmonization of data collection• Case report forms
– Collection by mail, fax, or internet
• Collection of images (CXR, CT, etc)• Collection of pathologic specimens
– Tumor, plasma, blood, normal tissue
• Central review of images and pathology?• Core laboratories
ICTW Punta del Este, Uruguay
Harmonization of data collection• Important for all trials
• For registration trials, some specific data to be collected may originate from discussions and agreement between the lead institution, the sponsor, and the country’s regulatory agency based on a particular trial, drug or claim– Case Report Forms, Central review of images
ICTW Punta del Este, Uruguay
Global variation in regulatory requirements• European Union Clinical Trials Directive:
– Directive 2001/20/EC– Required each member country in EU to pass national
legislation concerning clinical trials which evaluate new medications
• Problems– Little harmonization: 27 different laws for 27 countries– Covers all trials (even without new medications)– Barrier to international participation
ICTW Punta del Este, Uruguay
FDA Approvals
• Regulatory approval: substantial evidence of clinical benefit demonstrated prior to approval based on prolongation of life, a better life or an established surrogate of either of the above
• Accelerated approval (AA): designed to hasten the delivery of products appearing to provide a benefit for serious or life threatening illnesses lacking satisfactory treatments
• AA regulations 1992– 21 CFR Part 314, Subpart H (for drugs)– 21 CFR Part 601, Subpart E (for biologics)
ICTW Punta del Este, Uruguay
Critical Elements of Accelerated Approval• Serious or life threatening diseases• Provides a benefit over existing therapies• A surrogate reasonably likely to predict clinical benefit• Subject to the requirement to verify benefit• Post-marketing trials would usually be underway• Applicant should carry out studies with due diligence
If post-marketing studies fail to demonstrate clinical benefit or applicants fail to perform required post-marketing studies
with due diligence, FDA may withdraw approval, following an open public hearing
ICTW Punta del Este, Uruguay
EMA Approvals
• Approval types:– Normal, Exceptional, Conditional
• Conditional Marketing Authorization(CMA):– Demonstrates positive benefit:risk based on preliminary
evidence– “Specific Obligations” to provide further data necessary
to become Normal approval– Authorization valid for one year (renewable)– Clear information to patients and providers on the
conditional nature of the approval– Financial penalties if fail to observe obligations
ICTW Punta del Este, Uruguay
Data Reporting: Regulatory Requirements
• Method of data reporting• Multi-center guidelines• Reporting requirements • Collaborative agreement language
ICTW Punta del Este, Uruguay
Reporting of adverse events
• All clinical trials must collect data on adverse events associated with the trial.
• Some adverse events must be reported immediately, within 48-72 hours.
• Adverse events must be reported to the study sponsor, the independent ethics committee, and the national regulatory authority.
• The toxicities which patients experience may require modification to the trial.
ICTW Punta del Este, Uruguay
NCI Common Toxicity Criteria & Adverse Events (CTCAE)• Recently underwent 3rd revision (CTCAE v4)• Grade I: mild• Grade II: moderate• Grade III: severe• Grade IV: life-threatening• Grade V: death
• ~30% de la toxicidad es basada en sintomas> el resto en parametros de laboratorio o hallazgos clinicos
ICTW Punta del Este, Uruguay
Trial Data Monitoring
•Data Monitoring Committee (DMC) of Data Monitoring Safety Board (DMSB)
•To review safety and efficacy data from phase III trials on a continuing basis
•Recommendations to the trial “steering committee”•Closing the trial in case of large therapeutic benefit•Closing a trial for futility or safety •Changing the trial design / eligibility criteria•Early publication•Closing a poorly accruing trial
•Decisions with ethical, regulatory, commercial implicationsDagher RN and Pazdur R, in Anticancer Drug Development Guide, 2004; Chapter 20 p408
ICTW Punta del Este, Uruguay
Trial Data Monitoring – Early Closure Process
•If DMC/DMSB recommends early closure for safety, futility, efficacy, there is a regulatory process to be followed:
•Communications between government, leading group, pharma
•Dear doctor letter•Dear patient letter •Communication to other stake holders/partners•Communication to FDA
•Different regions/countries, may have different sop.
Dagher RN and Pazdur R, in Anticancer Drug Development Guide, 2004; Chapter 20 p408
ICTW Punta del Este, Uruguay
Insurance Requirements
• Institutional insurance– Protects local institution from claims that
institution made mistakes in giving therapy on trial or that the therapy on the trial was incorrectly designed
• Patient insurance– Provides insurance to cover treatment of
complications associated with trial
• Requirements vary from country to country
ICTW Punta del Este, Uruguay
Model Agreements
• Confidential Disclosure Agreement (CDA)
• Cooperative Research and Development Agreement (CRADA)
• Materials Cooperative Research and Development Agreement
• Clinical Supply Agreement (CSA)
• Material Transfer Agreement (MTA)
• Pediatric Preclinical Testing Program MTA
ICTW Punta del Este, Uruguay
Global variation in regulatory requirements: I• National and local regulatory approval
– Length of time required for review varies from country to country
– Some countries have established principle for only one fast review
• Adverse event reporting– US and European Union have slightly different
requirements– New US CTCAE version 4.0 should be more consistent
with European Union & ICH rules
ICTW Punta del Este, Uruguay
Global variation in regulatory requirements: II• Drug importation (import)
– paperwork required to import experimental drugs varies from country to country
– Legal rights to experimental drug can vary from region to region; Often one company has the rights to a drug in the US, while a second company has the rights to the drug outside the US
• Transportation of specimens– Some countries do not permit specimens to be shipped
to another country
ICTW Punta del Este, Uruguay
Room for improvement: Accrual• How can we strengthen international
collaboration and complete trials faster?• If a trial accrues too slowly, then the trial
result may no longer be important when the trial is finished.
• If a trial accrues too slowly, then doctors and patients lose interest in the study (in particular if a study of high complexity).
ICTW Punta del Este, Uruguay
Room for improvement: Overcoming barriers with a collaborative effort
• If we work together, then we can complete larger trials faster.
• If we work together, then we can complete trials for patients with a specific molecular biology or with a rare tumor or with a less common stage of cancer.
• If we work together, then we can study the impact of pharmacogenomics on cancer treatment.
ICTW Punta del Este, Uruguay
Room for improvement: Better planning, harmonization, and coordination• We must plan our clinical research together:
– Complementary trials– Joint trials
• We must harmonize regulation– Fast review, approval and activation of trials– Adverse event reporting– Insurance requirements
ICTW Punta del Este, Uruguay
Regulatory Structure: Conclusions
• Regulatory structure needs both to protect patient safety and facilitate clinical research
• Clinical trials help define optimal cancer care and guide public policy
• Government, academia, patients, public, and industry must collaborate to strengthen clinical trials
ICTW Punta del Este, Uruguay
Investments to Conduct National Trials
• National dialogue among cancer scientists, clinical investigators and practitioners
• National awareness campaign regarding cancer and clinical trials
• Develop national infrastructure
• Establish common registration, data submission and document approach
• Establish data submission network
• Establish quality assurance program
Building a National Network
ICTW Punta del Este, Uruguay
Building a National Network
Depends on what you have…and what you want
• Population available and accrual potential
• Number of advanced care centers & community hospitals
• Number of investigators and research nurses
• Private practice component in cancer care
• Cancers to be investigated
• Phase II or phase III trials
• Studies involving specific treatment modalities
• Single network or multiple networks (competing studies requires adequate patient base)
• Stable infrastructure
ICTW Punta del Este, Uruguay
Steps forward…
• Participate in international clinical trials by experienced cancer trial organization (e.g., EORTC)• Experience, GCP standards, data submission, submission
of biological specimens, oversight
