CONFIDENTIAL Copyright Cato Research Ltd. 1 How do clinical trials relate to the MRF1? Lynn Katsoulis SAPPRA 23 March 2007
CONFIDENTIAL Copyright Cato Research Ltd. 2 Points of View Planners Implementers Report writers
CONFIDENTIAL Copyright Cato Research Ltd. 3 Points of View Development plans Details order and timing of data capture Ensure all data collected before needed Non-clinical tests & Clinical trials Collect data according to overall development plan Report written after each experiment to trial Regulatory Submissions Mostly report entire process Justify next step which needs regulatory approval
CONFIDENTIAL Copyright Cato Research Ltd. 4 Drug development High risk industry Long and expensive process to prove drugs are safe and effective Development process costs up to $1.5 Billion Manufacturing Characterize compound Ensure same compound is produced throughout experimental phase and for each batch marketed Nonclinical experiments Collect sufficient data to show lack of risk to subjects Clinical trials Drugs given to carefully selected population Population expands throughout development process By end of development, should have sufficient data to extrapolate safety and efficacy of product to general population

CONFIDENTIAL Copyright Cato Research Ltd. 8 Drug Development Process: Steps from Test Tube to New Drug Application Review
CONFIDENTIAL Copyright Cato Research Ltd. 9 Objective at Each Stage Non-clinical Phase 1Phase 2Phase 3Phase 4 -In vitro pharmacology -In vitro safety -Respiratory, cardiac, hepatic, mutagenicity -In vivo safety -Single dose / dose ranging -Repeat dose / dose ranging -Proof of concept
CONFIDENTIAL Copyright Cato Research Ltd. 10 Toxicology Regulatory Requirements From ICH Guidance for Industry: M3 Nonclinical Safety Studies for the Conduct of Human Clinical Trials for Pharmaceuticals
CONFIDENTIAL Copyright Cato Research Ltd. 11 Objective – Phase 1 Non-clinical Phase 1Phase 2Phase 3Phase 4 -Healthy volunteers -Tolerance -Dose range -Pharmacokinetics -Several trials -About 5 to 30 subjects/trial
CONFIDENTIAL Copyright Cato Research Ltd. 12 Objective – Phase 2 Non-clinical Phase 1Phase 2Phase 3Phase 4 -Learn all there is to know about the drug -Dose comparison (2a) -May be several trials -Proof of concept -Numbers to small to show significant difference -20 to 60 subjects/trial
CONFIDENTIAL Copyright Cato Research Ltd. 13 Objective - Phase 3 Non-clinical Phase 1Phase 2Phase 3Phase 4 -Statistical confirmation of Phase 2 trial -Pivotal trials -Needs to be duplicated -Large trials - 100s to 1000s of subjects/trial
CONFIDENTIAL Copyright Cato Research Ltd. 14 Objective - Phase 4 Non-clinical Phase 1Phase 2Phase 3Phase 4 Post-marketing observations Confirm findings in general population Collect safety data in large patient group 1000s of subjects/trial
CONFIDENTIAL Copyright Cato Research Ltd. 15 Objective - Overall Non-clinical Phase 1Phase 2Phase 3Phase 4 -Each phase provides information to progress to next step -Marketing approval based on pivotal trials

CONFIDENTIAL Copyright Cato Research Ltd. 30 GXPs & Regulatory Submissions In order for data to be accepted as support for a marketing application: Data needs to be collected according to GLP and GCP using GMP product Needs to be shown in application Audits and inspections High enrollers for pivotal studies Any reason for suspicion Sponsor or CRO audit
CONFIDENTIAL Copyright Cato Research Ltd. 31 Documents Used in Clinical Trials Investigator brochure (ICH template) All information available on drug Updated throughout development program Used as basis of package insert Protocol (ICH template) Controlled document Needs regulatory and ethics committee approval If changed, amendment needs to be approved before being implemented Procedures manual Not controlled Used for site specific, and non-essential details Informed Consent Document (ICH template) Sufficient information to “enable” a subject to decide whether to participate or not Clinical study report (ICH template) Detailed report of findings from the clinical trial
CONFIDENTIAL Copyright Cato Research Ltd. 32 Clinical Trial Design Adequate control Pivotal trials need to be adequately controlled Blinding Randomization Placebo controlled Comparators If available, gold standard to be used Dose comparison At least two doses of the drug are compared A dose-comparison study may include additional treatment groups, such as placebo control or active control Dose-comparison trials usually include randomization and blinding of patients and investigators

CONFIDENTIAL Copyright Cato Research Ltd. 36 Three Common Designs 1. Retrospective Hypothesis generating; usually needs confirmatory clinical trial(s) 2. Prospective a. No possible effect in marker negative group Test must be available b. Possible effect in marker negative group If test not available: benefit/risk must be acceptable for whole population, even if efficacy is driven by marker positive group.
