The Best Pharmaceuticals for Children Act Anne Zajicek, M.D., Pharm.D. Pediatric Medical Officer National Institute of Child Health and Human Development National Institutes of Health
Best Pharmaceuticals for Children Act • Enacted January 2002, will sunset October 2007 • Continues exclusivity provision of FDAMA • Purpose: pediatric labeling
Pediatric Labeling • Pre-approval: Pediatric Research Equity Act • On-patent: • Best Pharmaceuticals for Children Act which continues the exclusivity provisions of FDAMA • Studies supported by the Foundation for the NIH • Off-patent: Best Pharmaceuticals for Children Act
Best Pharmaceuticals for Children Act • In pediatric oncology • prioritize new drugs for study • assure timely access to new treatments • develop pre-clinical models of pediatric cancers
Master List of all Off-Patent Drugs which lack adequate pediatric labeling N=169 • Consider for prioritizing: • Availability of S/E data • Are additional data needed? • Will new studies produce • health benefits? • Reformulation? Consultation with experts in pediatric practice and research Develop, prioritize, publish an Annual List N=15-20
Prioritization Process • FDA provides list of off-patent drugs lacking pediatric labeling to NICHD • NICHD requests input from ICs, other federal agencies, experts, advocacy groups • NICHD convenes annual prioritization meeting of experts in specific disease areas and pediatric clinical pharmacology • NICHD publishes an annual list of drugs in the FR which have been prioritized for study
Priority List • Developed by NIH • In consultation with • Institutes and Centers of the National Institutes of Health • Federal Agencies • Food and Drug Administration • Centers for Disease Control and Prevention • pediatric subspecialists and subspecialty groups
