What this trial studies

This observational study aims to gather data on the safety and outcomes for mothers and their infants who have been exposed to ozanimod during pregnancy. It focuses on understanding the maternal, fetal, and infant health implications of ozanimod exposure, allowing healthcare providers and patients to make informed decisions regarding treatment options during pregnancy. Participants must have a diagnosis of multiple sclerosis and be currently or recently pregnant, residing in the United States, Canada, or Germany.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women diagnosed with multiple sclerosis who have been exposed to ozanimod.

Not a fit: Patients who are not pregnant or who have been exposed to other S1P therapies during the first trimester may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety of ozanimod for pregnant women with multiple sclerosis, guiding treatment decisions.

How similar studies have performed: While this study focuses on a specific medication during pregnancy, similar observational studies have provided valuable safety data for other treatments in pregnant populations.
