Phase 2b Study of RO7837195 for Adults With Moderate to Severe Ulcerative Colitis Double-Blind, Placebo-Controlled Induction With Active Drug Extension

What this Trial Is About

Researchers are evaluating the efficacy of the drug RO7837195 compared to a placebo in adults with moderately to severely active ulcerative colitis UC who have not responded well to conventional or advanced treatments. This Phase IIb study aims to assess the safety, pharmacokinetics, and clinical effects of RO7837195 in this patient group. The study is sponsored by Genentech, Inc. and focuses on treatment outcomes including clinical remission at Week 12. Participants undergo a screening period lasting up to 5 weeks, followed by a 12-week induction phase where some receive RO7837195 and others receive a placebo. After this, all participants enter a 40-week active treatment extension phase receiving RO7837195 regardless of their initial response. This design allows comparison during induction and continued treatment for all in the extension phase. Safety follow-up occurs after the last dose of study treatment. Throughout the trial, participants will be monitored for clinical remission, response, and endoscopic improvements at Week 12, as well as adverse events and drug concentration levels up to Week 65. The study includes regular evaluations such as clinical assessments and laboratory tests to track treatment effects and safety. Total participation can last up to approximately 57 weeks, covering screening, treatment, and follow-up periods.
