Purpose

The objectives of Sub-Study 1 are to evaluate the efficacy, safety, and pharmacokinetics of risankizumab as induction treatment in subjects with moderately to severely active ulcerative colitis (UC), and to identify the appropriate induction dose of risankizumab for further evaluation in Sub-Study 2. The objective of Sub-Study 2 is to evaluate the efficacy and safety of risankizumab compared to placebo in inducing clinical remission in subjects with moderately to severely active UC.
