Is this trial a fit for you?

Likely a good fit

Children who weigh at least 10 kg with biopsy-confirmed active Crohn's disease and who have not adequately responded to or tolerated conventional or advanced therapies.

Probably not a fit

Patients with prior extensive bowel surgeries, monogenic causes of IBD, or current ulcerative colitis may not benefit from this therapy.

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

What this trial studies

This is a phase 3, double-blind, multicenter study in children with moderately to severely active Crohn's disease. Participants will receive Afimkibart as induction and maintenance therapy, with treatment continuing through the study to assess ongoing effects. Eligibility requires confirmed active disease, specific endoscopic scores, and prior inadequate response or intolerance to standard therapies. The trial will monitor pharmacokinetics, clinical outcomes, and safety in a pediatric population. Locations include sites in New York, Harlingen, and Brisbane, under Hoffmann-La Roche as lead sponsor.

Why it matters

Potential benefit: If successful, Afimkibart could offer better control of symptoms and longer-lasting remission for children with Crohn's disease.

How similar studies have gone: There is some precedent in pediatric Crohn's disease trials using new biologics to improve outcomes, but data for Afimkibart in children is still emerging.
