A Study of Mirikizumab (LY3074828) in Children and Teenagers With Ulcerative Colitis (UC)
This study is designed to evaluate how the body processes and gets rid of mirikizumab. The study will also evaluate safety and response in pediatric participants with UC taking mirikizumab.
The study will last about 52 weeks and may include up to 17 visits.
