Is this trial a fit for you?

Likely a good fit

Pregnant or recently pregnant adults with ulcerative colitis who reside in a country where ozanimod is prescribed for UC and have not been exposed to other S1P therapies during pregnancy.

Probably not a fit

Findings may show no clear association between ozanimod exposure and outcomes, giving limited actionable benefit for individuals.

What this trial studies

This is an observational study examining the relationship between ozanimod exposure during pregnancy and maternal, fetal, and infant outcomes in women with ulcerative colitis. It does not specify an intervention and will analyze data from pregnancies where ozanimod is prescribed for UC. Eligible participants are currently or recently pregnant adults with UC who live in countries where ozanimod is approved, excluding those with prior exposure to other S1P therapies during pregnancy. Lead sponsor is Bristol-Myers Squibb, with the study conducted virtually via PPD in the United States (Wilmington, NC). Findings may provide insights into safety and outcomes associated with ozanimod use in pregnancy.

Why it matters

Potential benefit: If successful, the study could clarify safety signals and inform decision-making for managing UC in pregnancy.

How similar studies have gone: This area has limited published results; the observational approach is commonly used to explore real-world safety signals for pregnancy exposure to UC therapies.
