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.
