Detailed Description:

The Tecfidera (dimethyl fumarate) Pregnancy Registry is a prospective, observational registry designed to evaluate pregnancy outcomes in women with multiple sclerosis (MS) who were exposed to dimethyl fumarate (DMF) since the first day of their last menstrual period (LMP) prior to conception or at any time during pregnancy. Women of childbearing potential are a considerable segment of the patient population affected by MS and are likely to be exposed to DMF around the time of conception and during pregnancy. Although the data are very limited, there is currently no evidence of increased risk of fetal abnormalities or adverse pregnancy outcomes associated with gestational exposure to DMF during the first trimester. Therefore, it is important to evaluate, in a global pregnancy registry, how DMF exposure may affect pregnancy and infant outcomes. Data will be collected on prospective pregnancies (i.e.enrollment prior to knowledge of outcome) at time of enrollment, 6 to 7 months gestation, and approximately 4,12 and 52 weeks after estimated date of delivery. The prevalence of spontaneous abortions, birth defects, and other pregnancy and infant outcomes will be calculated and compared to background rates from external sources such as the European Surveillance of Congenital Anomalies.


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Approximately 310 to 375 pregnant DMF exposed women will be enrolled in order to observe 300 prospective pregnancy outcomes. The infants born to these women will also be part of the population studied.


Key Inclusion Criteria:

  • Patient consent
  • Patient has a diagnosis of MS.
  • Documentation that the patient was exposed to DMF since the first day of her LMP prior to conception or at any time during pregnancy.

Key Exclusion Criteria:

  • Prenatal testing that could provide knowledge of the outcome of pregnancy must not have been performed prior to the time of enrollment (e.g., alpha fetoprotein, sonography, amniocentesis). However, initial maternal health assessment upon confirmation of pregnancy does not preclude participation in the Registry unless a patient tests positive for a medical condition associated with negative pregnancy outcomes (e.g., syphilis) in the opinion of the health care professional.
  • The outcome of the pregnancy must not be known at the time of enrollment.

NOTE: Other protocol defined Inclusion/ Exclusion criteria may apply.
