A Multicenter, Randomized, Double-Blind, Placebo Controlled Induction Study of the Efficacy and Safety of Risankizumab in Subjects With Moderately to Severely Active Crohn's Disease
The purpose of this study is to evaluate the efficacy and safety of risankizumab versus placebo during induction therapy in participants with moderately to severely active Crohn's disease (CD).
16 Years to 80 Years
