Could Two-Drug cocktails tame stubborn inflammatory bowel disease?
NCT ID NCT07697456
First seen Jul 13, 2026 · Last updated Sep 04, 2026 · Updated 7 times
Summary
This study tests whether combining risankizumab with either trosunilimab or ABBV-701 can safely reduce inflammation and improve symptoms in adults with moderately to severely active Crohn's disease or ulcerative colitis. Participants are randomly assigned to one of the combination treatments or a placebo. The goal is to see if these advanced therapies can achieve endoscopic remission, meaning the gut lining heals.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- risankizumab, trosunilimab, and ABBV-701
- What this could lead to
- If successful, these combination therapies could offer new treatment options for people with hard-to-control inflammatory bowel disease.
- What could go wrong
- This is an early-phase trial with a limited number of participants per arm, so results may not apply to everyone. Side effects are possible, and the combinations may not prove more effective than existing treatments.
