- Lead Sponsor
- AbbVie
- Brief Summary
Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most often affecting the bowels. It can cause many different symptoms including abdominal pain, diarrhea, tiredness, and weight loss. This study will assess how safe and effective risankizumab subcutaneous (SC) induction treatment is in treating moderately to severely active CD in adult participants.
Risankizumab is an approved drug for adults with CD. This study comprises of a Period A and a Period B. In Period A, participants are placed in 1 of 2 groups to receive either risankizumab SC or Placebo. In Period B, based on response, participants will receive risankizumab SC Dose B or Placebo. Participants who do not have improvement in CD symptoms at Week 12 will receive risankizumab SC Dose C and participants with worsening CD symptoms in period B will receive risankizumab SC. Approximately 276 adult participants with a diagnosis of moderately to severely active CD will be enrolled in approximately 250 sites globally.
Participants will receive SC induction treatment of risankizumab or matching placebo for up to 24 weeks in Period A and B. The duration of the study will be approximately 49 weeks.

Group Intervention Description Period A: Risankizumab Dose A Risankizumab SC Participants randomized to receive risankizumab Dose A administered by subcutaneous (SC) injection for up to 12 weeks during Period A. Period A: Placebo Placebo for risankizumab Participants randomized to receive placebo for risankizumab administered by Subcutaneous (SC) injection for up to 12 weeks during Period A. Period B: Risankizumab Dose B Risankizumab SC Participants randomized to receive risankizumab Dose A in Period A that achieved adequate response to receive risankizumab Dose B administered by subcutaneous (SC) injection for up to 12 weeks. Period B: Placebo Placebo for risankizumab Participants randomized to receive placebo risankizumab in Period A that achieved adequate response to continue to receive placebo for risankizumab administered by Subcutaneous (SC) injection for up to 12 weeks in Period B. Period B: Risankizumab Dose C Risankizumab SC Participants with inadequate response in Period A to receive Dose C administered by Subcutaneous (SC) injection for up to 12 weeks during Period B. Period C: Open-Label Risankizumab Dose D Risankizumab SC Participants who complete the Period B Week 24 visit to receive open-label risankizumab Dose D administered by subcutaneous (SC) injection for up to 52 weeks during Period C.
- Primary Outcome Measures
Name Time Method Percentage of Participants With Crohn's Disease Activity Index (CDAI) Clinical Remission (CDAI < 150) Week 12 The CDAI consists of 8 components; 7 are based on participant diary entries, participant interviews, physical examinations, measurement of body weight and height and 1 is based on laboratory analysis. CDAI clinical remission of Crohn's disease is defined as CDAI \< 150
Percentage of Participants With Endoscopic Response Week 12 The Simple Endoscopic Score for Crohn's Disease (SES-CD) assesses endoscopic disease severity by evidence of active intestinal mucosal inflammation. Endoscopic response is defined as a decrease in SES-CD \> 50% from Baseline (or for participants with isolated ileal disease and a Baseline SES-CD of 4, at least a 2-point reduction from Baseline)
- Secondary Outcome Measures
Name Time Method Percentage of Participants With Endoscopic Remission Week 12 Endoscopic remission: SES-CD ≤ 4 and at least a 2 point reduction versus baseline and no subscore greater than 1 in any individual variable
Change From Baseline of Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Week 12 The FACIT-Fatigue scale is a 13-item tool that measures an individual's level of fatigue during their usual daily activities over the past 7 days. Each of the fatigue and impact of fatigue items are measured on a 5-point Likert scale. The FACIT Fatigue Scale is the sum of the individual 13 scores and ranges from 0 to 52 where higher scores indicate better the quality of life. A positive change from baseline indicates improvement.
Percentage of Participants with a CR-100 Clinical Response Week 4 CR-100 defined as at least a 100-point reduction from Baseline in CDAI
Percentage of Participants With Clinical Remission Week 12 Clinical remission is defined as using the average daily Stool Frequency (SF) ≤ 2.8 and not worse than Baseline AND average daily Abdominal Pain (AP) score ≤ 1 and not worse than Baseline.
Percentage of Participants With Ulcer-Free Endoscopy Week 12 Ulcer-free endoscopy: SES-CD ulcerated surface subscore of 0 in participants with SES-CD ulcerated surface subscore ≥ 1 at Baseline
