What this trial studies

This observational study aims to compare the prevalence of major congenital malformations in two groups of pregnant women with Multiple Sclerosis (MS): those who have been exposed to BRIUMVI® (Ublituximab) and those who have not. Participants must have a diagnosis of MS and be currently or recently pregnant. The study will collect data from a registry to assess the outcomes of pregnancies in these cohorts, focusing on the safety of BRIUMVI® during pregnancy.

Who should consider this trial

Good fit: Ideal candidates include pregnant women diagnosed with Multiple Sclerosis who have either been exposed to BRIUMVI® or have not been exposed during their pregnancy.

Not a fit: Patients who have been exposed to anti-CD20 monoclonal antibodies or known teratogens during pregnancy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide critical insights into the safety of BRIUMVI® during pregnancy, potentially guiding treatment decisions for pregnant women with MS.

How similar studies have performed: While studies on the effects of medications during pregnancy are common, this specific evaluation of BRIUMVI® in pregnant women with MS is novel and has not been extensively tested.
