Preparing the Quality Overall Summary in the New Paradigm Michelle Herrera Foster, Ph.D. Regulatory Affairs Consultant CTD Quality Consulting
Topics • What is a Quality Overall Summary (QOS) • Regulatory Evolution • The New CMC Paradigm • QOS as a Key Reviewer Tool • QOS Pitfalls • QOS Keys • Conclusions
Module 2 NonclinicalOverview ClinicalOverview NonclinicalSummary ClinicalSummary NonclinicalStudy Reports ClinicalStudy Reports Quality Module 3 Module 4 Module 5 ICH M4 NOT Part of the CTD RegionalAdminInformation Module 1 The CTD QualityOverallSummary
What is a QOS • Summary of Module 3 (40-80 pages) • Discussion of critical product attributes, critical manufacturing parameters • Summary of key data, conclusions • Content linked to Module 3 • Content integrated with other summaries • Explanation of any guideline deviations
Module 3 3.2.S.1-.7, 3.2.P.1-.8, 3.2.A.1-.3, 3.2.R Detailed summaries: Manufacturing Testing Characterization Pharm. Devt. Validation (reports) Module 2 Same high level headings Key conclusions/data: Flow chart, crit steps Specs, batch range Critical attributes Critical parameters Critical criteria A Summary of Module 3
Regulatory Origins of the Quality Overall Summary • U.S. origin: NDA CMC Summary • EU origin: Pharmaceutical Expert Report • Japan origin: GAIYO • Required for all CTD submissions • Required for all Marketing Applications (CTD) in Europe, Canada, Japan; Canadian IND • Required 1/08 for all eCTDs to CDER
Regional Considerations for the Quality Overall Summary • US: Comprehensive QOS • US: ANDA Question-Based Review • FDA’s GMP Initiative • EU: Critique of Design Space or PAT approach • ICH Q8-Q9 • Canada: Templates for phase 1-3, IND/NDS • ICH initiative? – TBD for harmonization
The New CMC Paradigm • GMP Initative – Pharmaceutical Quality in the 21st century >>>>> Timely review and less supplements! • Risk-based and science-based • Process Analytical Technologies (PAT) • Quality By Design (QbD) > pre-defined quality • ICH Q8 – Pharmaceutical Development: design space, critical attributes and parameters • ICH Q9 - Quality Risk Management • ANDAs: Question-Based Review (QBR)
The Comprehensive QOS • Gives the reviewer an understanding of how the formulation and manufacturing process affects product quality and performance (safety and efficacy). • Focuses on critical quality attributes (CQA) and critical manufacturing parameters • Potentially a primary review document • Being explored in FDA’s CMC Pilot Program(see DIA ’06-07 CMC Track Sessions)
The QOS as a Key Reviewer Tool • To expedite marketing approval • CMC Development Plan, strategy • Management approval of the “bottom line” • Pre-meeting package • Gap analysis • Project management, Submission tracking • Enhanced cross-functional communication
QOS Pitfalls • A dump of module 3 data - “no value” per FDA (Chi-Wu Chen, DIA’06) • No critical assessment • Lack of rationales • No integration with other summaries • Just a regulatory requirement
QOS Keys To help us: • Assist the preparation • Facilitate review • Expedite approval
QOS Key #1Be Succinct • High-level data summaries and conclusions • Focus on key messages • Focus on critical attributes and parameters • Provide useful context • Give the reviewers what they need to know to approve your product!
QOS Key #2Bottom Line Up Front (BLUF) • Conclusions First • Don’t make the reviewer wade through paragraphs to find out the bottom line • Provide clear rationales supporting critical parameters and specifications • Describe key issues and their resolutions • Address key deviations from guidance • Organize the information so that it is easy to follow and understand
QOS Key #3Address key agency trends • ICH Q8 Pharmaceutical Development, Quality by Design • ICH Q9 Quality Risk Management • Risk-based review • Consider Question-Based Review, e.g. “How was your product designed to have your defined critical attributes?”
QOS Key #4Link to Module 3 • Be consistent with module 3 • Cross-reference/hyperlink to module 3 • Make it easy for your reviewers to find the data supporting key messages in the Quality Overall Summary
Conclusions • The QOS is a key tool for agency review • A well-written QOS could expedite approval • The QOS can be the basis for internal CMC planning and tracking • The QOS should assess risk and provide scientific rationales • Be succinct and use BLUF • Meeting the reviewers’ needs will help you meet your own needs, i.e. approval! • Stay tuned for future QOS guidance
