Phase III Study of Afimkibart Injection for Treating Moderate to Severe Ulcerative Colitis

What this Trial Is About

Researchers are evaluating the safety and effectiveness of induction therapy using Afimkibart also called RO7790121 in people with moderately to severely active ulcerative colitis UC. This Phase III study is designed as a multicenter, double-blind, placebo-controlled trial to compare Afimkibart with a placebo. The study aims to understand how well Afimkibart works to induce remission in UC and its safety profile. Participants will be randomly assigned to one of two groups. One group will receive Afimkibart through an intravenous IV infusion followed by a subcutaneous SC injection, while the other group will receive matching placebo infusions and injections. The treatment period lasts 12 weeks, during which researchers will assess the effects of the therapies. Throughout the study, participants will undergo various assessments including evaluations of clinical remission, endoscopic improvement, histologic changes, and symptom severity at specified time points such as baseline, Week 2, and Week 12. Safety will be monitored by tracking adverse events for up to 30 weeks after starting treatment. The total participation duration spans the treatment and follow-up periods to gather comprehensive data on outcomes and safety.
