A Multicenter, Randomized, Double-Blind, Placebo Controlled 52-Week Maintenance and an Open-Label Extension Study of the Efficacy and Safety of Risankizumab in Subjects With Crohn's Disease
The study consists of 3 sub-studies, as follows: - Sub-study 1 (Randomized, double-blind, placebo controlled study) to evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in participants with moderately to severely active Crohn's disease (CD) who responded to risankizumab induction treatment in Study M16-006 or Study M15-991 - Sub-study 2 (Randomized, exploratory maintenance study) to evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in participants who responded to induction treatment in Study M16-006 or Study M15-991; - Sub-study 3 (Open-label, long-term extension study) to evaluate long-term safety of risankizumab in participants who completed Sub-study 1, Sub-study 2 or the Phase 2, open-label extension study M15-989, or participants who responded to induction treatment in Study M16-006 or Study M15-991 with no final endoscopy due to the Covid-19 pandemic.
