Phase 2 Study of Multiple Treatments for Adults With Moderate to Severe Ulcerative Colitis or Crohns Disease Evaluating Mirikizumab and LY4395089 Treatments

What this Trial Is About

Researchers are investigating new treatments for adults with moderately to severely active ulcerative colitis or Crohns disease under a master protocol called Study IIBD. This Phase 2 trial evaluates multiple drugs to understand their safety and effectiveness in managing these conditions. Participants will be assigned to specific sub-studies and randomized to treatment groups, with the study lasting at least 62 weeks. The study includes two treatment periods. In the first period, participants may receive mirikizumab intravenously, or a combination of the oral drug LY4395089 with intravenous mirikizumab. Those who respond to treatment will then enter a second period where they receive mirikizumab through subcutaneous injections. These steps allow researchers to assess different dosing methods and combinations of these drugs. Participants will be monitored regularly throughout the study, including screening tests and laboratory evaluations to ensure eligibility and safety. Researchers will track the number of participants allocated to each treatment group up to day 42 as a primary outcome. The study involves randomization without masking and continues until at least 62 weeks, with ongoing assessments to evaluate treatment effects and monitor health outcomes.
