Is this trial a fit for you?

Likely a good fit

Ideal candidates are children with a confirmed diagnosis of moderately to severely active Crohn's disease who have not responded adequately to previous treatments.

Probably not a fit

Patients with complications of Crohn's disease that may require surgery or those with certain severe manifestations of the disease may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the efficacy, safety, and tolerability of mirikizumab in pediatric participants diagnosed with Crohn's disease. Participants will be screened and randomly assigned to receive either mirikizumab or another intervention. The study includes a 12-week induction period followed by a maintenance phase lasting up to 52 weeks, with a total duration of approximately 74 weeks and up to 19 visits. The study aims to assess how well mirikizumab is absorbed in the body and its overall effectiveness in treating active Crohn's disease in children.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for managing Crohn's disease in pediatric patients.

How similar studies have gone: Other studies have shown promise with similar biologic therapies for Crohn's disease, indicating potential for success with this approach.
