Phase 3b Study of Mirikizumab With or Without Tirzepatide in Adults With Moderate to Severe Ulcerative Colitis and Obesity or Overweight

What this Trial Is About

Researchers are evaluating whether treatment with both mirikizumab and tirzepatide compared to mirikizumab and placebo can reduce or eliminate symptoms of moderately to severely active ulcerative colitis UC in adults who are also overweight or have obesity. This Phase 3b randomized controlled study aims to determine if this combination treatment leads to clinical remission and at least a 10% reduction in body weight. Participants receive mirikizumab initially by intravenous IV infusion followed by subcutaneous SC injections. They are randomly assigned to receive either tirzepatide SC or a placebo SC alongside mirikizumab. The treatment period lasts for 52 weeks, with the whole study participation lasting up to 61 weeks. Both study drugs and placebo are administered under medical supervision. During the study, participants are monitored regularly for symptom improvement and weight loss. Researchers assess clinical remission, endoscopic response, histologic-endoscopic mucosal improvement, bowel movement urgency, and histologic remission at weeks 24 and 52. Safety and treatment effects are carefully followed throughout the trial. Participants undergo evaluations to measure changes in UC symptoms and body weight over the study period.
