Study 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.

Eligibility

Primary outcome measure(s)

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