Researchers are evaluating the safety and effectiveness of LY4268989 compared to a placebo in adults with moderately to severely active ulcerative colitis (UC). This Phase 2 study focuses on participants who have had UC for at least 3 months and have specific disease activity scores. The study aims to understand how well LY4268989 works in treating this condition over a long period. Participants will receive either LY4268989 or a placebo, both administered orally. The study includes a treatment period lasting up to approximately 108 weeks, not including the screening phase. Participants are monitored to assess their response to the medication, including whether they achieve clinical remission based on the Modified Mayo Score (mMS). During the study, researchers will conduct various assessments to monitor disease activity and participant safety. They will track the percentage of participants achieving clinical remission at Week 10 and among those who responded at Week 10, the remission status at Week 52. The study involves regular evaluations, including endoscopic confirmation of disease activity and safety monitoring over the entire duration.
