Is this trial a fit for you?

Likely a good fit

Probably not a fit

Patients who are not pregnant or those who have not been diagnosed with multiple sclerosis will not benefit from this study.

What this trial studies

This observational study aims to estimate the risk of major congenital malformations in infants born to women with multiple sclerosis who were exposed to diroximel fumarate during early pregnancy. It will compare pregnancy outcomes between women exposed to diroximel fumarate and those who were either unexposed to disease modifying therapies or exposed to other therapies like Avonex and Tysabri. The study will gather data on pregnancy outcomes from women with MS to better understand the effects of this medication during pregnancy.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety of diroximel fumarate during pregnancy for women with multiple sclerosis.

How similar studies have gone: Other studies have successfully evaluated pregnancy outcomes in women with multiple sclerosis and their exposure to various disease modifying therapies, indicating that this approach has been tested before.
