This trial investigates the safety and effectiveness of risankizumab compared to vedolizumab in adults with moderate to severe ulcerative colitis (UC) who have not previously received targeted therapies. Ulcerative colitis is an inflammatory bowel disease causing inflammation and bleeding in the rectum and colon. The study is a Phase 3b, randomized, open-label trial enrolling about 530 participants across 285 sites worldwide. Participants will be randomly assigned to receive either risankizumab or vedolizumab. Those in the risankizumab group will receive the drug intravenously during the initial induction phase, followed by subcutaneous injections for maintenance. Participants in the vedolizumab group will receive the drug intravenously throughout the study. The treatment period lasts 44 weeks for risankizumab and 46 weeks for vedolizumab, following a screening period of up to 35 days. During the study, participants will attend regular outpatient visits for medical assessments, side effect evaluations, and to complete questionnaires. Researchers will monitor disease activity and drug safety, focusing on the percentage of participants achieving endoscopic improvement by week 48. The total study duration is approximately 69 weeks for risankizumab and 71 weeks for vedolizumab recipients.

Researchers are evaluating the effectiveness and safety of Afimkibart (RO7790121) as both an induction and maintenance treatment for people with moderately to severely active Crohn's disease in this Phase III, multicenter, double-blind, placebo-controlled study. The goal is to understand how well Afimkibart works compared to placebo in managing symptoms and disease activity over time. Participants will receive either Afimkibart or a matching placebo. Afimkibart is given both as an intravenous infusion and as a subcutaneous injection. This treat-through study means participants continue on the assigned treatment throughout the study period, allowing evaluation of both initial and ongoing therapy effects. During the study, participants will be regularly assessed to measure clinical remission using the Crohn's Disease Activity Index (CDAI) and to check for endoscopic response at week 52. Researchers will monitor safety and treatment effects throughout, with the entire participation lasting up to one year. Assessments include clinical evaluations and endoscopic examinations to track disease changes and treatment impact.
