Summary
This is a Phase 2/3 study that comprises 5 substudies designed to evaluate the efficacy, safety, and tolerability of oral etrasimod as therapy in adult participants with moderately to severely active Crohn's disease (CD) who are refractory or intolerant to at least 1 of the current therapies for CD (ie, corticosteroids, immunosuppressants, or biologics). The overall duration of this study is up to 282 weeks, inclusive of the Screening Period, Treatment Period of up to 274 weeks (Induction, Extension or Maintenance, and Long-term Extension Periods), and the 4-Week Follow-Up Period for safety assessment.
Description
This study includes 5 substudies:
Substudy A - Phase 2: A Phase 2, randomized, double-blind, substudy to assess the safety, tolerability, and efficacy of oral etrasimod therapy in participants with moderate to severe CD that supports the selection of an induction and maintenance dose(s) for Phase 3.
Substudy 1 - Phase 2: A Phase 2b randomized, double-blind, placebo-controlled, dose-ranging induction substudy to evaluate etrasimod as induction therapy and select an induction and maintenance dose(s) for continued evaluation in Phase 3.
Substudy 2 - Induction: A Phase 3 randomized, double-blind, placebo-controlled substudy to evaluate etrasimod as induction therapy.
Substudy 3 - Maintenance: A Phase 3 randomized, double-blind, placebo-controlled substudy to evaluate etrasimod as maintenance therapy. Participants from Substudy 1 and Substudy 2 will be enrolled in Substudy 3.
Substudy 4 - Long-Term Extension: A long-term extension substudy for participants who complete at least 52 weeks of treatment. Participants from Substudy 3 and Substudy A are planned to be enrolled in Substudy 4.
