Interventions
Registration Number
NCT05923073
Lead Sponsor
Janssen Research & Development, LLC
Brief Summary

The purpose of this study is to evaluate the clinical and endoscopic efficacy of guselkumab in pediatric participants with Crohn's Disease (CD) at the end of maintenance therapy (Week 52) among participants who were in clinical response to guselkumab at Week 12.

Detailed Description

Participants screened in the MACARONI-23 platform study could be randomized to guselkumab to participate in this intervention specific arm of the study.

Inclusion Criteria
  • Participants must have a diagnosis of Crohn's Disease (CD) or fistulizing CD, with active colitis, ileitis, or ileocolitis, confirmed at any time in the past by clinical, endoscopic, and histologic criteria.
  • Participants must have moderately to severely active CD (as defined by a baseline Pediatric Crohn's Disease Activity Index [PCDAI] score greater than or equal to [>=] 30)
  • Participants must have endoscopy with evidence of active CD defined as Simple Endoscopic Score for Crohn's Disease (SES-CD) score greater than or equal to (>=) 6 (or >=4 for participants with isolated ileal disease) within 1 month of receiving study intervention at Week 0
  • 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 intravenously (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
Exclusion Criteria
  • Participants has complications of CD such as symptomatic strictures or stenosis, short gut syndrome, or any other manifestation that might be anticipated to require surgery.
  • Participants must not have an abscess
  • Participants must not have any kind of bowel resection within 26 weeks or any other intra-abdominal surgery within 12 weeks of baseline

Open-label induction phase: Guselkumab Intravenously (IV)GuselkumabParticipants will receive guselkumab dose IV based on their body weight during the 12-week open-label induction phase.
Open-label induction phase: Guselkumab Subcutaneously (SC)GuselkumabParticipants will receive guselkumab dose SC based on their body weight during the 12-week open-label induction phase.
Double-blind maintenance phase: Guselkumab SC Dose Regimen 1GuselkumabAt the end of the induction phase, Week 12 responders will be randomized into the double-blind maintenance phase to receive guselkumab dose regimen 1 SC based on their body weight up to Week 48.
Double-blind Maintenance Phase: Guselkumab SC Dose Regimen 2GuselkumabAt the end of the induction phase, Week 12 responders will be randomized into the double-blind maintenance phase to receive guselkumab dose regimen 2 SC based on their body weight up to Week 48.
Open-label maintenance phase: Guselkumab SCGuselkumabWeek 12 non-responders will not be randomized and will enter an open-label maintenance phase to receive guselkumab SC dosing regimen based on their body weight up to Week 48.
Primary Outcome Measures
NameTimeMethod
