Strategies for More Rapid Translation of Cellular Therapies for Children: A US Perspective

Clinical trials for pediatric diseases face many challenges, including trial design, accrual, ethical considerations for children as research subjects, and the cost of long-term follow-up studies. In September 2011, the Production Assistance for Cellular Therapies Program, funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health, sponsored a workshop, "Cell Therapy for Pediatric Diseases: A Growing Frontier," with the overarching goal of optimizing the path of discovery in research involving novel cellular therapeutic interventions for debilitating pediatric conditions with few or no available treatment options. Academic and industry investigators in the fields of cellular therapy and regenerative medicine described the obstacles encountered in conducting a clinical trial from concept to conclusion. Patient and parent advocates, bioethicists, biostatisticians, regulatory representatives from the US Food and Drug Administration, and translational scientists actively participated in this workshop, seeking to identify the unmet needs specific to cellular therapies and treatment of pediatric diseases and propose strategies to facilitate the development of novel therapies. In this article we summarize the obstacles and potential corrective strategies identified by workshop participants to maximize the speed of cell therapy translational research for childhood diseases.
