Transforming Performance of Clinical Trials in Pediatric Type 2 Diabetes: A Consortium Model.

Completing phase 3 trials of new drugs for youth with type 2 diabetes is challenging. The Pediatric Diabetes Consortium (PDC) of U.S. pediatric treatment centers developed a Consortium model to improve the efficiency of successfully completing these trials. An aim of the PDC model is to utilize the resources of the PDC Coordinating Center and Executive Committee to improve study protocols, centralize interactions with sponsors, and oversee the performance of PDC Clinical Centers. Key features include a Consulting Group to improve protocol design; Master Service Agreements between the Coordinating Center and Clinical Centers covering confidentiality agreements and contract language; negotiation of a standard Site Budget with Contract Research Organizations (CROs)/Sponsors that reflect actual Clinical Center costs; Weekly Conference Calls with CROs/sponsors to track progress of Clinical Center launches, Monthly Oversight Calls with investigators and study Coordinators to track Clinical Center performance, discuss enrollment strategies, and identify emerging problems. The Consortium model played a key role in the completion of the pivotal trial of liraglutide for treatment of youth with type 2 diabetes. PDC centers also played a pivotal role in exceeding the projected number of randomized subjects needed by two ongoing studies that are nearing completion. While the Consortium model is still a work in progress, PDC has assisted in the successful launch of new type 2 diabetes studies, and negotiations are in underway for PDC participation in pediatric type 1 diabetes and other diabetes-related studies.
