PEDIATRIC TRIALS NETWORK March 27, 2014 A project of the Best Pharmaceuticals for Children Act
Why are studies in children difficult? Limited number of patients with the disease No “healthy child/baby volunteer” Low rates of parental informed consent Perceived study risks Limited blood volume and timed sampling Sick population – increases variability Lack of clinical pharmacology expertise Lack of pediatric PK/PD modeling expertise
How Did The PTN Start? “Create an infrastructure for investigators to conduct trials that improve pediatric labeling and child health.” –Sponsored by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) –Network for studying drug product formulation, age-appropriate drug dosing, efficacy, safety, and device validation –Success: Completed trials that improve dosing, safety information, labeling, and ultimately child health
Pediatric Trials Network PI: Benjamin Since 2010, ~25 ongoing projects, 12 clinical trials Phase 1 and 2 studies All therapeutic areas 5 CSRs submitted to FDA 4-6 potential label changes Training of fellows/junior faculty
