8. 1974 AAP Committee on Drugs issues guidelines for evaluating drugs for pediatric use

9. 1977 AAP issues guidelines for ethical conduct in pediatric studies “It is morally imperative, therefore, to formally study drugs in children so that they can enjoy appropriate access to existing and new therapeutic agents”

10. 1979 AAP Committee on Drugs provides report of therapeutic categories with pediatric need

11. PEDIATRIC LABELING30 YEAR EXPERIENCEUNITED STATES • 1973: 78% Rx DRUGS NOT LABELED FOR CHILDREN • 1992: 81% Rx DRUGS NOT APPROVED FOR CHILDREN • 1984-95: 80% OF NME’s APPROVED WITHOUT PEDIATRIC LABELING • 1996-98: >80% OF NME’s APPROVED WITHOUT PEDIATRIC LABELING

WORKSHOP ON DRUG DEVELOPMENT AND PEDIATRIC POPULATIONSRECOMMENDATIONS1990 • FDA commissioner, PMAF Pharmaceutical Manufacturers Association, and AAP sponsored a three-day workshop in Washington, DC to look at the impediments to doing drug studies in children • FDA FACILITATE APPROVAL OF DRUGS FOR CHILDREN • LEGISLATION TO ADDRESS ECONOMIC ISSUES • PROACTIVE STANCE BY PHARMACEUTICAL INDUSTRY • NIH FUND CENTERS FOR PEDIATRIC STUDIES

13. Pediatric Labeling Legislation • The FDA Modernization Act of 1997, provided marketing incentives to manufacturers who conduct studies of drugs in children (patent exclusivity for 6 months) • The Pediatric Rule of 1998, required pediatric studies and labeling of new drugs with therapeutic benefit to children • struck down in the courts due to lack of authority • The Pediatric Research Equity Act (PREA) and Best Pharmaceuticals for Children Act (BPCA)in 2002 passed by Congress • preserved the voluntary patent exclusivity incentive program and provided the FDA the authority to require studies in children to evaluate safety/efficacy of new drugs • BPCA and PREA were made into permanent law in 2012
