What this trial studies

This study evaluates the concentrations of ozanimod and its major metabolites in the breast milk of women who are receiving treatment with this medication. It aims to understand the potential effects of ozanimod on breastfed infants by analyzing breast milk, plasma, and blood samples. The study focuses on women who are at least two weeks postpartum and have delivered a normal-term infant. The findings could provide valuable insights into the safety of ozanimod for breastfeeding mothers and their infants.

Who should consider this trial

Good fit: Ideal candidates are adult women who are currently being treated with ozanimod and are at least two weeks postpartum with a normal-term infant.

Not a fit: Patients who are not breastfeeding or have infants born prematurely may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help ensure the safety of ozanimod for lactating women and their breastfed infants.

How similar studies have performed: While studies on drug concentrations in breast milk are common, this specific investigation into ozanimod is novel and has not been extensively tested.
