Quality: tight procedures, reproducibility of manufacturing, specifications, pass FDA inspection Safety: low risk demonstrated in tests on animals and patients Effectiveness: benefit demonstrated in tests in animals and patients - 20 - Substantial Evidence: How Do We Get It ? Test the product in animals and patients; see if it works and if it does any harm Use “controlled conditions of testing” to eliminate the possibility that test results are wrong Apply rigorous scientific, medical and regulatory standards throughout - 21 - “FDA’s Satisfaction”: How Do We Know What FDA Wants ? Regulations state what must be done, in general Guidelines provide advice on what is required for specific products Meetings: very specific technical discussions and negotiations on individual products Correspondence: technical negotiations on very fine points - 22 - Doing Clinical Trials in the U.S. The Role of the IND - 23 - The Investigational New Drug (IND) Application as the Platform for Drug Development Lab Development Discovery Basic PreResearch Clinical Clinical Testing I STRATEGY IND II III IIIb IV NDA Commercial Market Marketing Product Launch Sales SNDAs - 24 - Information Needs for Regulatory Strategy Identify similar drugs/treatments for specific indications Obtain regulatory approval documents (EPARs, FDA Approval Packages/SBAs) Identify all relevant guidance documents, both regulatory (EMEA, FDA) and medical (ASCO, etc.) - 25 - Information Needs for Clinical Development Strategy Define market size for indication, including by class of drugs Incidence & prevalence of indications in various countries to develop strategy for selection of patient groups and trial locations re: proof-of-concept studies Identify competing products in development (pipeline) Literature search to identify pivotal clinical trials re: standard trial protocol examples - 26 - Why do we need an IND? An IND is required in order to conduct clinical trials in the United States IND (Investigational New Drug Application) is an exemption from the law that prohibits interstate shipment of unapproved drugs IND Submitted Chem & Mfg NDA Submitted Mfg Scaleup Synthesis & Purification Formulation Development Animal Studies Short term Animal Long term Animal Phase 1 Clinical Studies Phase 2 Phase 3 PK Studies Time - 27 - - 28 - IND Principal Goals Clinical Protocol Subject must not be exposed to unnecessary risks SAFETY CMC CMC procedures ensure that the drug is adequately reproducible and stable Preclinical/Other Data Adequate evidence that the drug is “reasonably” safe for administration to humans - 29 - Information Needs for INDs Safety, pharmacokinetics, and toxicity of study drug or drugs similar to study drug in animals and humans – to provide evidence that drug is “reasonably” safe for administration to humans Safety and efficacy of a class of drugs via a specific administration (IV, oral, etc.) in specific indications to justify a protocol dose selection - 30 - The Phases of Clinical Development Phase 1 • 20-80 Subjects • Patients or Normal Volunteers • Metabolism/Pharmacologic Actions • Side Effects with Increasing Dose • Early Efficacy Information • ADME Phase 3 • Hundreds to Thousands of Subjects • Patients with Disease Under Study • Well Controlled Studies • Efficacy and Safety Phase 2 • Several Hundred Subjects • Patients with Disease Under Study • Well Controlled Studies • Efficacy and Safety Phase 4 • Post-NDA Approval • Epidemiology Studies • Marketing Studies - 31 - The New Drug Application (NDA) The vehicle through which sponsors formally request that the FDA approve a new pharmaceutical for marketing in the US, on the basis of demonstrated quality, safety and efficacy. - 32 - The Common Technical Document Format for the NDA Module 1 Not Part of the CTD Regional Administrative Information 1.1 Submission ToC CTD Table of Contents 2.1 CTD Introduction 2.2 Module 2 Quality Overall Summary 2.3 Nonclinical Overview 2.4 Nonclinical Written and Tabulated Summaries 2.6 Clinical Overview 2.5 Clinical Summary 2.7 Module 3 Module 4 Module 5 Quality 3 3.1 ToC Nonclinical Study Reports 4 4.1 ToC Clinical Study Reports 5 5.1 ToC CTD - 33 - Information Needs for NDA Submission and Beyond Literature search for safety and efficacy in humans of study drug in comparable indications, administrations, or dosages – clinical trials, review articles, case studies, etc. Literature search on all published studies for specific drug and indication for 505(b)(2) submissions (“paper” NDAs) After NDA approval, the obligation to report drug safety information from patients and/or additional studies grows exponentially and is a significant information management challenge (pharmacovigilance) - 34 - Interactions with FDA - 35 - Meetings with FDA During Early Drug Development Can Shorten NDA Review and Approval Time NDA Review Time (mos) 35 30 25 20 No Meeting Meeting 15 10 5 0 PreIND Phase Phase End of Phase 1 2 Phase 3 2 Source: DiMasi and Manocchia, DIA Journal 1997 - 36 - Meeting Regularly with FDA is a Success Factor in Drug Development Maintain ongoing relationship Avoid misunderstandings Communicate new data Highlight and jointly resolve problems before they become too large Anticipate difficulties Monitor changes in FDA attitude or expectations of data Avoid surprising each other Accelerate development process FDA Center for Drugs holds >1000 industry meetings every year - 37 - Regulatory Approval is Earned Gradually, Not in a “Final and Glorious Battle” with FDA Planning for the Target Labeling early in development Thorough development vision and plans Ongoing communication with FDA: Build Trust Data-driven development plan revisions Strong project management on both sides Learn from mistakes and take timely corrective actions in agreement with FDA - 38 - Key Ingredients of Successful Meetings Science/ Medicine Information Professionals Regulatory Good Knowledge Mtg Meeting Process Management - 39 - Success Factor No. 1: Science and Medicine FDA decision-making is driven by data FDA relies on internal reviewers and external experts to review data and make decisions FDA decisions can change based on changes in science, medical knowledge and medical practice If no data, then no positive FDA decision Good science, good medicine and good study designs are keys to success - 40 - Success Factor No. 2: Regulatory Knowledge Company representatives must know the rules (regulations, guidelines) Regulatory precedents (previous FDA decisions on similar issues) are important It is sometimes possible to “push” the FDA into a dialogue (e.g. post-approval commitments; generic biologics) Being well-prepared is key - 41 - Success Factor No. 3: Meeting Process Management FDA meetings must be planned and managed in a very specific way There is a defined process for FDA meetings Preparation and documentation are essential Rehearsals are important for the theater … and they are important for FDA meetings too ! - 42 - FDA Meetings During Drug Development Pre-IND EOPII Pre-NDA AdComm Label Lab Development Discovery Basic PreResearch Clinical Clinical Testing I IND II III IIIb IV NDA Commercial Market Marketing Product Launch Sales SNDAs - 43 - Types of FDA Meetings TYPE PURPOSE Pre-IND Verify acceptability End of Phase I (rare) Confirm early safety End of Phase II Confirm early efficacy;
