E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate whether treatment with IL-23 inhibitors is superior to adult placebo in achieving clinical remission and endoscopic response in pediatric participants with moderately to severely active CD at Week 52 who do not require modification of IP regimen, IP rescue therapy, or non-IP rescue therapy |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the efficacy of treatment with mirikizumab in achieving clinical response or clinical remission by PCDAI or CDAI at Week 12 |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1.Participants must have a diagnosis of CD or fistulizing CD, with active colitis, ileitis, or ileocolitis, confirmed at any time in the past by clinical, endoscopic, and histologic criteria. 2.Participants must have moderately to severely active CD (as defined by a baseline PCDAI score >30). 3.Participants must have endoscopy with evidence of active CD defined as as SES-CD score ≥6 (or ≥4 for participants with isolated ileal disease) during screening into this study. 4.Participants must have a prior or current CD medication history that includes either inadequate response, loss of response to or failure to tolerate current treatment immunomodulators or with oral or IV corticosteroids or have received biologic therapy/JAK inhibitor for the treatment of CD and have a documented history of inadequate response, loss of response (LOR), or intolerance to the biologic therapy/JAK inhibitor. |
|
E.4 | Principal exclusion criteria |
1. Participants must not have complications of CD such as symptomatic strictures or stenosis, short gut syndrome, or any other manifestations that might be anticipated to require surgery. 2. Participants must not have an abscess. 3. Participants must not have any kind of bowel resection within 26 weeks or any other intra-abdominal surgery within 12 weeks of baseline. |
