9 Key Elements of Science & Standards Division: Organization Flow

10 Drivers for Change  Increase/improve interface between different parts of USP  Increase efficiency on work flow within SSD –External to USP –Internal within USP  Expert Committees were recently restructured to manage monographs and reference standards  To make project ownership for each product clear (single point of accountability in the context of the team)  Maximize capacity of our work load (identify constraints and provide solutions)

11  Products (monographs, reference materials) to our customers are synchronized and reference standards are available as early as possible  There is a portfolio owner for each segment of the portfolio for Small Molecules, Biologics, Excipients, Dietary Supplements, Food Ingredients, General Chapters/Pharmacists’ Pharmacopeia, Healthcare Quality Standards  A uniform criteria for priority setting. Drivers For Change: Outcomes

17  The Basics  Management  The Future—Science  The Future—Putting It Together Topics

18 Drug Product Monographs and General Chapters

19  A PBM can include: –Specified tests Identification, Assay, others –Specific acceptance criteria 97%-103%, NMT 0.1%, others –Criteria-based procedures with: Procedure Performance Measures (Precision, accuracy, others) Procedure Performance Acceptance Criteria (% RSD, Bias, R 2, others) Performance Based Monograph

20 Glutathione Example: Assay

21  USP General Chapter Validation of Compendial Procedures defines the critical validation parameters necessary to validate a procedure.  Pre-set criteria assure that an acceptable procedure will reliably assess whether an article meets acceptance criteria of its Tests.  USP now terms these criteria as Procedure Performance Measures (PPM) and the Procedure Performance Acceptance Criteria (PPAC).  PPM and PPAC may be used to determine suitability of multiple acceptable procedures. PPMs and PPACs

22  Small Molecules Collaborative Group, Williams RL, Abernethy DR, Koch WF, Hauck WW, Cecil TL. Performance-based monographs. Pharm Forum. 2009;35(3):  Hauck WW, DeStefano AJ, Cecil TL, Abernethy DR, Koch WF, Williams RL. Acceptable, equivalent, or better: approaches for alternatives to official compendial procedures. Pharm Forum. 2009;35(3):  Koch WF, Hauck WW, de Mars SS, Williams RL. Measurement science for food and drug monographs: toward a global system. Pharm Res. 2010;27:  Williams RL, de Mars S, Koch WF, Hauck WW, Cecil TL. USP responses to comments on Stimuli article: performance-based monographs. Pharm Forum. 2010;36(4): References

23 USP Medicines Compendium:

24 Key Points About the Medicines Compendium  MC is applicable to medicines legally marketed outside of the US; USP-NF covers articles legally marketed in the US  Science based  Authoritative, not official; the approval by the Council of Experts makes it authoritative  Supplements donor model  Helps modernize USP-NF  Experimental, unique, and innovative
