Diet plus drugs may keep Crohn's at bay in kids
NCT ID NCT04777656
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a special diet (Crohn's Disease Exclusion Diet) to standard medication helps children with unstable Crohn's disease have fewer flare-ups over a year. About 120 kids aged 6-17 will be randomly assigned to either diet plus medication or medication alone. The goal is to see if the diet can improve disease control and reduce relapses.
