Is this trial a fit for you?

Likely a good fit

Adults aged 18-75 with moderately to severely active UC, previous nonresponse or intolerance to at least one approved UC therapy, and specific Mayo score criteria.

Probably not a fit

Participants with severe or fulminant UC, Crohn's disease, active infections, or contraindications to the study drug may not benefit.

What this trial studies

This is a multicenter, randomized, double-blind, placebo-controlled phase 3 trial evaluating the safety and effectiveness of ponesimod (VSP-128) in adults with ulcerative colitis. Eligible participants have a history of inadequate response or intolerance to prior UC therapies and meet specific Mayo score criteria. Participants are assigned to receive either ponesimod or placebo, with ongoing monitoring for adverse events and disease activity. The trial is conducted at two Vanda investigational sites in California and Tennessee, led by Vanda Pharmaceuticals. The study aims to determine if ponesimod can provide meaningful improvement in UC symptoms and quality of life.

Why it matters

Potential benefit: If successful, participants may experience reduced disease activity and improved symptoms related to ulcerative colitis.

How similar studies have gone: Ponesimod and other S1P receptor modulators have shown potential in related inflammatory conditions, but results for UC are still being established and this trial investigates efficacy in this indication.
