Brief summary
A multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of Ponesimod (VSP-128) in patients with moderately to severely active ulcerative colitis
Interventions
Ponesimod administered orally once daily. Participants are randomized 2:1 to Ponesimod or placebo during a 16-week double-blind period. A 14-day titration is followed by a stable dose daily from Day 15 through end of treatment. Participants may enter a 36-week open-label extension receiving Ponesimod.
Matching placebo administered orally once daily during a 16-week double-blind period (2:1 randomization). A mock 14-day titration is used to maintain blinding. Participants may enter a 36-week open-label extension receiving Ponesimod.
