Zinnia Lactation Study

Are you currently 18 years or older, breastfeeding (or planning to), and diagnosed with multiple sclerosis or ulcerative colitis?

Are you currently taking Zeposia® (ozanimod) while breastfeeding?

You can help future breastfeeding individuals, doctors, and researchers understand the safety of medications that can provide some relief.

Are you a healthcare provider who treats breastfeeding individuals with multiple sclerosis or ulcerative colitis?

Help us learn more about the safety of using Zeposia® (ozanimod) for the treatment of these conditions during breastfeeding.

About the Zinnia Lactation Study

This study collects health information and samples (milk and blood) from individuals who take Zeposia® (ozanimod) while they are breastfeeding. Information and samples (blood only) will also be collected from the breastfed infant. Researchers use the information and samples to learn whether a medicine can cross over into breast milk. If it does cross over, the samples can help researchers learn how much of the medicine is in breast milk and whether it affects the breastfed infant.

The goal of the study is to help doctors, patients, and researchers learn about the safety of taking ozanimod while breastfeeding. Breastfeeding individuals in the United States who are being treated with ozanimod may be able to join the study.
