Phase 2 Study Comparing LY4395089 and Mirikizumab Together Versus Mirikizumab Alone in Adults With Moderate to Severe Crohns Disease

What this Trial Is About

This trial investigates the safety and effectiveness of combining a drug called LY4395089, which is a farnesoid X receptor FXR agonist, with mirikizumab compared to using mirikizumab alone in adults who have moderately to severely active Crohns disease. This Phase 2 study is part of a larger research protocol focused on inflammatory bowel diseases and will last about 62 weeks. Participants are assigned to one of two groups. In the first study period, one group receives mirikizumab via intravenous IV infusion, while the other group receives both LY4395089 orally and mirikizumab IV. In the second study period, participants who respond to treatment will stop LY4395089 and receive mirikizumab subcutaneously SC. This design allows comparison of the combined treatment versus mirikizumab alone. Throughout the study, participants will undergo assessments including endoscopic evaluations to measure Crohns disease response up to Week 12, clinical remission checks, and fecal calprotectin tests to monitor inflammation. The study includes regular visits for treatment administration and monitoring, with the total participation lasting approximately 62 weeks. Safety and efficacy are closely observed during the trial.
