| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
SS 1:Randomized, double-blind, placebo-controlled maintenance Evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in subjects with moderately to severely active Crohn's disease (CD) who responded to risankizumab induction treatment in Study M16-006 or Study M15-991 and had a Baseline (of induction) eligibility SES-CD of ≥ 6 (≥ 4 for isolated ileal disease).
SS 2:Randomized, exploratory maintenance Evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in subjects with moderately to severely active CD who responded to induction treatment in Study M16-006 or Study M15-991.
SS 3:Open-label long term extension Evaluate long-term safety of risankizumab in subjects who completed SS 1,2, or subjects who enroll directly into SS3(from either induction studies or another AbbVie risankizumab CD study).Additional objectives are to further investigate long-term efficacy and tolerability of risankizumab. |
|
| E.2.2 | Secondary objectives of the trial |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Entry and completion of Study M16-006, Study M15-991 or another AbbVie risankizumab Crohn's disease study. The final endoscopy for studies M16-006 and M15-991 may be missing during the coronavirus SARS-CoV-2 pandemic due to local regulations prohibiting endoscopy and subjects may be allowed to enroll in Sub-study 3 should they meet clinical response. 2. Achieved clinical response, defined as ≥ 30% decrease in average daily SF and/or ≥ 30% decrease in average daily AP score, and both not worse than Baseline of the induction study, at the last visit of Study M16-006 or Study M15-991. This is not applicable for subjects enrolling from another AbbVie risankizumab Crohn's disease study. 3. If female, subject must meet the criteria as stated in protocol Contraception Recommendations.
|
|
| E.4 | Principal exclusion criteria |
Subjects should not be enrolled in Study M16-000 with high grade colonic dysplasia or colon cancer identified during Study M15-991 or another AbbVie risankizumab Crohn's disease study if the final endoscopy was performed prior to enter M16-000 or is considered by the Investigator, for any reason to be an unsuitable candidate for the study.
Subject who has a known hypersensitivity to risankizumab or the excipients of any of the study drugs or the ingredients of CHO, or had an AE during Study M16 006 , Study M15-991 or another AbbVie risankizumab Crohn's disease study that in the Investigator's judgment makes the subject unsuitable for this study.
Subject is not in compliance with prior and concomitant medication requirements throughout Study M16-006, Study M15-991 or another AbbVie risankizumab Crohn's disease study. |
