This study comprises three sub-studies. The objective of sub-study 1 is to characterize the dose-response, efficacy, and safety of ABT-494 compared to placebo in inducing clinical remission in order to identify the induction dose of ABT-494 for further evaluation in sub-study 2. The objective of sub-study 2 is to evaluate the efficacy and safety of ABT-494 compared to placebo in inducing clinical remission in participants. The objective of sub-study 3 is to evaluate the efficacy and safety of ABT-494 compared to placebo in achieving clinical remission in participants who had a response following induction with ABT-494.
