NCT ID NCT04280510
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study is looking at why the immune system attacks the gut in people with celiac disease and other immune-related gut disorders. Researchers will collect blood and tissue samples from 200 adults to study immune cells and genes. The goal is to better understand what goes wrong, not to test a new treatment.
