Development p pplan to assess the safety y and efficacy of pharmaceuticals in pediatric patients – Penalties Regulation 2008 • Fines for non non-compliance compliance with conditions of marketing authorisation, including commitments • Future EU Legislation g – EU Pharmaceutical Package • A communication and 3 legislative proposals (Patient Information, Pharmacovigilance and Counterfeit Medicines) adopted in 2008 N E O S New Er a of Safet y 12/22 RMP throughout Product life cycle (1) • Limitations Li it ti of f clinical li i l ttrial i l ddata t – Selected population (demographics, co-morbidities, concomitant medications) – Limited sample size and duration of follow up – Educated investigators, informed patients, rigorous monitoring in a studyy environment • RMP with rigorous pharmacovigilance program for earlier detection of safety signal and institution of appropriate action to protect patient safety – Rare, idiosyncratic SADRs from spontaneous AE reporting after extensive market k exposure e.g. acute liver l failure l withh Rezulin l – Complex SADRs from post-marketing pharmacoepidemiology study/clinical observational studies or clinical trials e.g. Increase in CV events which are common in the target population with Vioxx & Avandia N E O S New Er a of Safet y 13/22 RMP throughout product life cycle (2) • Although submitted usually during approval, RMP is to be developed early in clinical development and throughout the product cycle to protect patient safety, with the following essential components: – A pharmacovigilance h i il plan l ffor early l ddetection t ti of f new risk i k (potential risk and missing information) or change in the severity & frequency of known risk – A risk mitigation plan to minimize all known and potential risks associated with the use of the drug – Ongoing assessment of the effectiveness of the risk mitigation plan with modifications if required – FDA REMS for a drug or biologic must include: a timetable for submission b of assessments – annually ll for the h first 3 years, N E Owith S overall assessment at 7 years & failure to comply leads to 14/22 New Er a of Safet y misbranded product/penalty Maximizing Industry/Regulatory Agencies Collaboration on RMP Product knowledge resides within the pharmaceutical company (a full function team of scientists/physicians) Regulatory g y agencies g have unique q access into confidential safety y information, both developmental and postmarketing safety data, of similar class of drugs not available to the public and therefore can provide id valuable l bl advice d i to the h d development l off RMP and d critical ii l review of the post marketing pharmacovigilance program Close collaboration between regulatory agencies and pharmaceutical p a aceut ca co companies pa es is s mandatory a dato y in de development e op e t o of a an appropriate RMP N E O S New Er a of Safet y 15/22 The benefit risk ratio and expanded capabilities are driving further changes Healthcare Pressures: Economic Pressures: New Technologies: g Benefit-Risk Ratio Benefit-Cost Ratio Expanded Capabilities N E O S New Er a of Safet y 16/22 Industry Opportunity: Developing Safer and More Effective Drugs g Drug Response Rate in percentage Analgesics Efficacy 80 Safety GSK Sanofi Aventis 60 Novartis Cancer 40 Bayer 20 Novartis 0 N 1 Spears E etOal.,STrends Mol Med, 2001;
