Phase 3 Evaluation of Guselkumab Treatment in Children Ages 2 to 17 with Moderate to Severe Crohns Disease

What this Trial Is About

Researchers are evaluating the clinical and endoscopic effects of guselkumab in children aged 2 to 17 years with moderately to severely active Crohns Disease who show clinical response at Week 12. This Phase 3 study focuses on assessing the treatments impact at the end of a one-year maintenance period in pediatric participants with this condition. The trial is sponsored by Janssen Research & Development, LLC. Participants first receive guselkumab either intravenously or subcutaneously based on their body weight during a 12-week open-label induction phase. Those who respond at Week 12 are then randomly assigned to one of two subcutaneous guselkumab dosing regimens for a double-blind maintenance phase lasting up to Week 48. Non-responders at Week 12 enter an open-label maintenance phase with guselkumab subcutaneous dosing up to Week 48. Throughout the study, participants undergo clinical and endoscopic evaluations to measure remission and response rates, including endoscopic scores and clinical remission at Week 52. Additional assessments include growth measurements such as weight and height changes, and plasma concentrations of guselkumab. Safety is monitored with adverse event tracking up to Week 64, with the total duration of participation spanning just over one year.
