Failed Pediatric Drug Development Trials.

Pediatric product development initiatives have stimulated the development of therapies for children, resulting in improved product labeling, increased identification of adverse events, and development of new pediatric formulations. However, 42% of recently completed pediatric trials have failed to establish either safety or efficacy, leading to an inability to label the product for use in children.(1) Characterizing these failed trials, including common contributing factors, is imperative to designing better pediatric trials in the future.
