How well does a new medication work for severe colon inflammation in Japan

This trial is following about 200 adults in Japan who have moderate to severe ulcerative colitis—a condition that causes inflammation and bleeding in the colon and rectum. You would take risankizumab, an already-approved medication for this condition, exactly as your doctor prescribes it as part of your regular care. The study will track how well the medication works for you over about three years.

While this medication is approved and used to treat ulcerative colitis, researchers want to understand how well it actually works for patients in real-world everyday practice—not just in controlled research settings. This information will help doctors and patients make better treatment decisions.
