Brief summary

In this study, researchers will learn more about the effects of diroximel fumarate (DRF), also known as VUMERITY®, when taken during pregnancy in people with multiple sclerosis, also known as MS. In MS, the immune system attacks the nerves in the brain and spinal cord. The affected areas are called lesions. The damage makes it difficult for the brain and spinal cord to function and send messages throughout the body. MS can be a progressive disease, which means it may get worse over time. In relapsing forms of MS (RMS), new symptoms may happen, and existing symptoms may get better or worse over time. DRF is an approved drug that is used to treat people with RMS. This is known as an "observational" study, which collects health information about study participants without changing their medical care. The main goal of this study is to collect birth and health information from 3 groups of participants and their babies. These groups are: * Those who took DRF during their pregnancy * Those who took disease-modifying therapies (DMTs) for RMS during their pregnancy, but not DRF. DMTs are drugs that slow how the disease develops over time, not just relieve symptoms. * Those who did not take any drugs for RMS during their pregnancy The main question researchers want to learn about in this study is: • How many participants' babies were born with major congenital malformations (MCMs)? MCMs are problems with how a baby's body forms before birth. In this study, researchers will measure how often the following outcomes happen and compare them between groups: * Loss of pregnancy before 20 weeks * Loss of pregnancy at or after 20 weeks (stillbirth) * Babies born early (before 37 weeks) * Babies who are smaller than expected for the stage of pregnancy * Live births This study will be done as follows: * The study includes data in adult women with multiple sclerosis on pregnancies happening between October 29th, 2019 and July 31st, 2030. Information will start being collected when the participant decides to join the study. * Medical records and clinical notes will be reviewed at the end of the study. * The study will include information from pregnancy through delivery, and for babies up to 1 year after birth. * The study is planned to end by 30th April 2031.

Detailed description

The primary objective of the study is to estimate the prevalence of major congenital malformations (MCMs) and compare the prevalence between the diroximel fumarate (DRF) and comparator groups. The secondary objectives of the study are to estimate the incidence of spontaneous abortion (SA) and compare the incidence between the DRF and comparator groups; to estimate the incidence of preterm birth and compare the incidence between the DRF and comparator groups; to estimate the incidence of stillbirth and compare the incidence between the DRF and comparator groups; to estimate the prevalence of small for gestational age (SGA) and compare the prevalence between the DRF and comparator groups; and to estimate the incidence of live birth and compare the incidence between the DRF and comparator groups.

Design outcomes

Primary

MeasureTime frameDescription
Number of Major Congenital Malformations (MCMs)Up to 52 weeks postdeliveryMCMs includes abnormalities in structural development that are medically or cosmetically significant are present at birth and persist in postnatal life unless or until repaired.

Secondary

MeasureTime frameDescription
Number of Spontaneous AbortionsBefore 20 weeks of gestationSpontaneous abortion is defined as the loss of a fetus due to natural causes before 20th week of gestation.
Number of Preterm BirthsAt or before the 37 weeks of gestationPreterm birth is defined as a live birth at or before the 37th week of gestation.
Number of StillbirthsAt or after the 20 weeks of gestationStillbirth is defined as the loss of pregnancy at or after the 20th week of gestation.
Number of Small for Gestational Age (SGA)Up to 52 weeks postdeliverySGA is defined as birthweight below the 10th percentile for gestational age.
Number of Live BirthsUp to delivery (approximately 10 months)Livebirth is defined as a delivered fetus with any sign of life (e.g., voluntary movement, heartbeat) regardless of gestational weeks.
