Is this trial a fit for you?
✓Likely a good fit
Children aged 2 up to just under 12 years with a diagnosis of moderately to severely active ulcerative colitis who meet health criteria and are eligible under the study’s medication and medical history rules are ideal candidates.
✕Probably not a fit
Patients with Crohn’s disease, indeterminate colitis, history of fistulas, severe extensive colitis, or microscopic/ischemic/infectious colitis are excluded and are unlikely to benefit from this protocol.

What this trial studies
This Phase 2 interventional trial gives pediatric participants etrasimod and follows them closely for safety, effectiveness, and how the drug is processed in the body (pharmacokinetics) over a 52-week treatment period. Children who complete the 52 weeks may continue in a long-term extension for up to four additional years (five years total after enrollment). The study enrolls participants with moderately to severely active ulcerative colitis and permits some background UC therapies while excluding patients with Crohn’s disease, fistulas, severe extensive colitis, or other non-UC colitis types. Visits and monitoring occur at academic medical centers in Canada and Germany under sponsorship by Pfizer.
Why it matters
Potential benefit: If successful, etrasimod could provide a new oral treatment option to reduce inflammation and symptoms in children with moderately to severely active ulcerative colitis.
How similar studies have gone: Previous adult trials of etrasimod and other S1P receptor modulators have shown clinical benefit in ulcerative colitis, so this pediatric study builds on existing adult data.
