To Evaluate Efficacy and Long-term Safety of Ozanimod in Japanese Subjects With Moderately to Severely Active Ulcerative Colitis

Phase 3
Active, not recruiting
Conditions
Colitis, Ulcerative
Interventions
Other: Placebo
Registration Number
NCT03915769
Lead Sponsor
Celgene
Brief Summary

Japanese patients with moderate or severe active ulcerative colitis as a subject when ozanimod 0.46 mg or 0.92 mg is orally administered is evaluated about dose response, efficacy and safety with placebo as a control.

Detailed Description

Following the up to 5-week Screening Period, eligible subjects will be randomized to enter the 12 weeks placebo-controlled Induction Period (IP). Subjects who are responders at Week 12 will continue on their assigned treatment in the 40-week Maintenance Period (MP). Non responders at Week 12 have the option to enter the Open-label Extension (OLE). Subjects who complete the MP will be given the option to participate in the OLE. Subjects that enter the MP and experience disease relapse will also have the option to enter the OLE. The OLE will continue until marketing launch (about 4 years of ozanimod for Ulcerative colitis (UC), or until the Sponsor discontinues the development program.
