What this trial studies

This observational study aims to estimate the prevalence of major congenital malformations in women exposed to Diroximel Fumarate during pregnancy and compare these outcomes with those of women exposed to other treatments for Multiple Sclerosis. It will also evaluate the incidence of spontaneous abortion, preterm birth, stillbirth, and small for gestational age infants among the different groups. The study will gather data from women with Multiple Sclerosis who have had their last menstrual period between October 2019 and July 2030 and have continuous medical coverage. By analyzing these outcomes, the study seeks to provide insights into the safety of Diroximel Fumarate during pregnancy.

Who should consider this trial

Good fit: Ideal candidates for this study are pregnant women with a diagnosis of Multiple Sclerosis who have been exposed to Diroximel Fumarate.

Not a fit: Patients who are pregnant and have been exposed to known teratogens during the relevant exposure window will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical information on the safety of Diroximel Fumarate for pregnant women with Multiple Sclerosis, potentially guiding treatment decisions.

How similar studies have performed: Other studies have explored pregnancy outcomes in women with Multiple Sclerosis, but this specific comparison involving Diroximel Fumarate is novel.
