Can a simple topical treatment stop a common Post-Surgery complication in ulcerative colitis?
NCT ID NCT07773948
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests whether applying 5-ASA (mesalamine) directly to the ileal pouch after surgery for ulcerative colitis can prevent pouchitis—a painful inflammation that affects more than half of patients. Adults with UC who are scheduled for pouch surgery are randomly assigned to receive either topical 5-ASA or a placebo. The study tracks how many participants develop pouchitis over two years, aiming to see if this simple preventive step can reduce the risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- topical 5-ASA (mesalamine)
- What this could lead to
- If effective, this could offer a simple, low-cost way to prevent pouchitis, improving quality of life for many ulcerative colitis patients after surgery.
- What could go wrong
- This is a phase 4 trial, but results are not yet known. The drug may not reduce pouchitis risk, and some patients may experience intolerance or side effects.
