NCT ID NCT07576452
First seen Jun 27, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
This study compares four different sequences of biologic drugs (infliximab, filgotinib, ustekinumab, and vedolizumab) in 240 adults with moderate to severe ulcerative colitis. The goal is to see which order of treatments works best to achieve and maintain remission without steroids. Participants will be followed for two years with regular check-ups and endoscopies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- infliximab, filgotinib, ustekinumab, vedolizumab
- What this could lead to
- If successful, this study could identify the best order of biologic treatments for ulcerative colitis, improving remission rates and quality of life.
- What could go wrong
- This is a Phase 4 trial comparing existing drugs, so no new treatment is being discovered. Results may not apply to all patients, and individual responses can vary.
