- Phase 2: Change from Baseline in the Crohn's Disease Activity Index (CDAI) Score at Week 12 [ Time Frame: Baseline and Week 12 ]
The CDAI score will be assessed by collecting information on 8 different Crohn's disease-related variables, with scores ranging from 0 to approximately 600. A decrease over time indicates improvement in disease activity.
- Phase 3: Clinical Remission at Week 12 [ Time Frame: Week 12 ]
Clinical remission is defined as CDAI score less than (<) 150 points.
- Phase 3: Endoscopic Response at Week 12 [ Time Frame: Week 12 ]
Endoscopic Response is measured by the Simple Endoscopic Score for Crohn's Disease (SES-CD). The SES-CD is based on the evaluation of 4 endoscopic components across 5 ileocolonic segments, with a total score ranging from 0 to 56.

A Study of the Efficacy and Safety of Guselkumab in Participants With Moderately to Severely Active Crohn's Disease
|
A Phase 2/3, Randomized, Double-blind, Placebo- and Active-controlled, Parallel-group, Multicenter Protocol to Evaluate the Efficacy and Safety of Guselkumab in Participants With Moderately to Severely Active Crohn's Disease
|
The purpose of this study is to evaluate the clinical efficacy (GALAXI 1), clinical and endoscopic efficacy (GALAXI 2 and GALAXI 3) and safety of guselkumab in participants with Crohn's disease.
|
This program consists of 3 separate studies: a 48-week Phase 2 dose-ranging study (GALAXI 1) and two 48-week Phase 3 confirmatory studies (GALAXI 2 and GALAXI 3). In Phase 2, safety and efficacy of guselkumab dose regimens will be evaluated to support the selection of induction and maintenance dose regimens for confirmatory evaluation in Phase 3. Participants who complete the 48-week Phase 2 or Phase 3 studies may be eligible to enter the long term extension (LTE). Throughout the 3 studies, efficacy, pharmacokinetic, biomarkers, and safety will be assessed.
