This study is known as a "drug interaction study." The purpose is to learn how commonly used drugs or substances (midazolam, warfarin, dextromethorphan, omeprazole, and caffeine) and their breakdown products get into the bloodstream after taking a "cocktail" (combination) of them before and after multiple doses of mirikizumab.
The study will last about 23 weeks for each participant. Screening must be completed within 4 weeks prior to study start.
