      The Gastroenterology Regulatory Endpoints and the Advancement of Therapeutics VI Workshop, held on July 22, 2021, provided a forum for patients and representatives from academia, industry, patient advocacy groups and FDA to discuss drug development for celiac disease (CeD). The workshop focused on the approach to histologic assessments in clinical trials, considerations for pediatric drug development, and use of a gluten challenge (GC) in clinical trials. Given that no histologic scoring system is widely accepted for use in clinical trials at this time, early phase clinical trials should ideally explore a variety of histologic scales and assess the histologic findings of celiac disease as individual measures to inform future trials. When planning pediatric drug development in CeD, appropriate use of extrapolation of efficacy data from adequate, well-controlled studies in adults could facilitate timely access to safe and effective therapies for pediatric patients. Identification of a fit-for-purpose pediatric clinical outcome assessment could further advance pediatric drug development. Histologic responses to the GC depend on exposure dose and duration; short exposures do not appear to cause long-term consequences. However, the GC should be incorporated into clinical trials in a thoughtful manner to generate interpretable results and ensure patient safety. Ongoing collaboration between all stakeholders will facilitate the development of safe and effective therapeutics for CeD.
