Study Comparing Intravenous (IV)/Subcutaneous (SC) Risankizumab to IV/SC Ustekinumab to Assess Change in Crohn's Disease Activity Index (CDAI) in Adult Participants With Moderate to Severe Crohn's Disease (CD)

United States, Argentina, Australia527 participantsStarted 2020-09-30

Plain-language summary

Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. This study will evaluate how well risankizumab works compared to ustekinumab. This study will assess change in Crohn's Disease Activity Index (CDAI). Risankizumab is an investigational drug being developed for the treatment of Crohn's Disease (CD). Ustekinumab is an approved drug for the treatment of moderate and severe CD. Participants are randomly assigned to one of the three treatment groups. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to ustekinumab. Around 508 adult participants with moderate to severe CD will be enrolled in approximately 307 sites worldwide. In Part 1, participants assigned to risankizumab will receive intravenous (IV) doses of risankizumab at Week 0, 4,8 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. Participants assigned to ustekinumab will receive intravenous (IV) dose of ustekinumab at Week 0 and subcutaneous (SC) doses every 8 weeks thereafter through Week 48. In Part 2, participants who received risankizumab in Part 1 and completed the Week 48 visit will continue to receive SC risankizumab for up to an additional 220 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Confirmed diagnosis of Crohn's disease (CD) for at least 3 months prior to Baseline. * Crohn's disease activity index (CDAI) score 220 - 450 at Baseline. * Confirmed diagnosis of moderate to severe Crohn's Disease as assessed by stool frequency (SF), abdominal pain (AP) score, and Simple Endoscopic score for CD (SES-CD). * Demonstrated intolerance or inadequate response to one or more anti-tumor necrosis factor (TNF) therapies. Exclusion Criteria: * Current diagnosis of ulcerative colitis or indeterminate colitis. * Receipt of CD approved biologic agents prior to Baseline (as detailed in protocol), or any investigational biologic or other agent or procedure prior to Baseline (as detailed in protocol). * Prior exposure to p19 and/or p40 inhibitors (e.g., risankizumab and ustekinumab). * Currently know complications of CD (strictures, short bowel, etc).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
