GMPs for the 21st Century May 2008

  1. 1. 5/9/2008 CDER Office of Compliance and the Critical Path Initiative “Since the initial report, we have broadened our Pharmaceutical Quality for thinking about the Critical Path Initiative to include veterinary medicines, generic drugs, and even foods. the 21st Century For all product areas, the basic idea is to reduce uncertainty about product performance throughout the product lif cycle through scientific research. W h d life l h h i ifi research. We have h set up a large number of collaborations with partners to Temple University get this research done, in areas as disparate as drug May 06, 2008 manufacturing and clinical trial design.” -Janet Woodcock 8/17/07 Joseph Famulare, Deputy Director Sustainability of product quality throughout the product FDA CDER Office of Compliance lifecycle is a major role of the Office of Compliance FDA Initiatives: A Quality Timeline Scope of Recent Guidances Process Product Monitoring/ Design Continuous Process Manufacturing Verification Design 2004 2005 2006 2007 2008 ICH Q8/Q8(R) - Pharmaceutical Development PAT Guidance ICH Q9 – Quality Risk Management FDA Guidance on Quality Systems (9/06)/ ICH Q10 – Pharmaceutical Quality Systems CGMP Revisions Modernizing and harmonizing CGMPs Phased approach …1-2-3 …1- Revisions to First Phase – ‘non-controversial’: ‘non- Withdraw proposed 1996 changes CGMP R Regulations l ti Change no asbestos filter to no particle shedding material Potable water can be as defined by, e.g., Japan and EU Equipment needing to be sterilized shall be sterilized 1

Testing and Release for Distribution: For each Data, Trends and Investigations: requirement batch of drug product there shall be appropriate under US CGMP to review annually laboratory determination.... Modern manufacturing methods and controls make this possible in real time Doesn t Doesn't have to be end product Not all trends require investigations, however Real time release is sufficient and does not have to “unexplained discrepancies” do be backed up with “traditional end product testing” Manufacturers should be better able to understand nor is it appropriate to substitute at will those with real time monitoring and controls The “need” to do “traditional testing” is covered by stability Process Validation Process Validation Old Approach ? Process Validation for Active Two decades old Pharmaceutical Ingredients is enforceable Design/development foundation weak under the Statute Emphasizes replication at commercial scale p p does not promote a fuller process understanding Statutory cGMP provision at 501(a)(2)(b) of making deviation/problem analysis dubious the Federal Food, Drug, and Cosmetic Act biased batches feasible and valuable Does not sufficiently enable appropriate CGMP guidance available - ICH Q7A regulatory oversight Process Validation Lifecycle Approach to Process Validation The ‘process’ of process validation Lifecycle Overall validation is not “complete” but ongoing Requires comprehensive process design to identify and Series of activities taking place over mitigate significant sources of variability achieve process understanding the ‘life’ of the product/process life’ May incorporate risk management Recognizes that more knowledge will be gained during commercial distribution 6
