Background: Treatment options for youth with type 2 diabetes (T2D) are limited compared to those for adults with T2D. As pediatric clinical trials in T2D are difficult to complete, due to lower prevalence and population related recruitment challenges, clinical sites are often reluctant to participate. Protocol design, often not appropriate for pediatrics, administrative and financial burden related to study participation further reduce site interest.

Methods: The Pediatric Diabetes Consortium (PDC) is a network of 49 U.S. diabetes centers working together to improve care for children with diabetes. Recognizing challenges associated with pediatric T2D clinical trial participation, the PDC developed a network model to improve efficiency for both sites and sponsors.

Innovations: A consulting group was formed to assist with protocol design appropriate for T2D pediatric studies. A PDC master agreement with sites eliminates need for negotiation of standard contract language between sponsor and each site, allowing for a single contract between the PDC and sponsor. A single budget, based upon a clinical trial budget template, reflecting actual site costs, is negotiated by the PDC for all sites. Central archiving of site metrics eliminates need for a feasibility survey before site selection occurs. Monthly site calls led by an investigator oversight committee provide opportunities to discuss enrollment strategies, study challenges and best practices, and provide real-time feedback to sponsor.

Conclusion: Efficiencies established by the PDC network model reduce workload for sites and start-up timeline for sponsors. Population-appropriate trial design improves recruitment opportunities. Ongoing site engagement helps to identify and mitigate protocol issues in real-time. The network model improves likelihood of successful trial operations. To date, 26 PDC sites have participated in at least 1 of 3 studies, enrolling 137 across studies so far, contributing to successful recruitment ahead of projected schedule.
