RESUMO
OBJECTIVES: The development of medical devices for children faces unique challenges that have contributed to a paucity of devices specifically designed and tested for children. Increased knowledge on research activities for pediatric devices can guide optimal study design and ensure timely dissemination of clinical findings. METHODS: We performed a cross-sectional analysis of interventional studies registered on ClinicalTrials.gov, initiated January 1, 2017, through December 12, 2022, evaluating a Food and Drug Administration-regulated class II or III device, and enrolling any pediatric patients (aged ≤17 years). Data were extracted from ClinicalTrials.gov on study characteristics and from Devices@FDA on device features. For completed studies, we determined whether results were reported in a peer-reviewed publication as of December 27, 2022. RESULTS: Among 482 studies, 406 (84.2%) examined a class II device and 76 (15.8%) a class III device. The most common device types were diabetes-related devices (N = 57, 11.8%) and monitors and measurement devices (N = 39, 8.1%). Most studies were single-center (N = 326, 67.6%), used a nonrandomized (N = 255, 52.9%), open label (N = 350, 72.6%) design, and were funded by academic institutions (N = 278, 57.7%) or industry (N = 142, 29.5%). A total of 291 (60.4%) studies included a primary outcome of only efficacy without safety endpoints. Among completed studies, more than half (N = 64, 51.6%) enrolled <50 participants and 71.0% (N = 88) <100. After median follow-up of 3.0 years, results were available in publications for 27 (21.8%) completed studies. CONCLUSIONS: Our findings serve to inform programs and initiatives seeking to increase pediatric-specific device development. In addition to considerations on ensuring rigorous trial design, greater focus is needed on timely dissemination of results generated in pediatric device studies.
