Brief summary

The primary objectives of the study are to estimate the risk of major congenital malformations (MCMs) in infants born to women with multiple sclerosis (MS) who were exposed to diroximel fumarate (DRF) at any time from 2 weeks after the first day of their last menstrual period (LMP) up through the first trimester of pregnancy and to comparatively evaluate pregnancy outcomes with MCMs in women with MS who were exposed to DRF at any time from 2 weeks after the first day of their LMP through the first trimester of pregnancy with the following: i) women with MS who were unexposed to disease modifying therapies (DMTs) and, ii) women with MS who were exposed to other DMTs (e.g., Avonex and Tysabri Pregnancy Registries). The secondary objective of the study is to evaluate pregnancy outcomes in women with DRF exposure at any time from 2 weeks after the first day of their LMP through the end of pregnancy compared with the following: i) women with MS who were unexposed to DMTs, ii) women with dimethyl fumarate (DMF) exposure, iii) women with MS who were exposed to other DMTs (e.g., Avonex and Tysabri Pregnancy Registries), and iv) women without MS (e.g., women from external, general population comparators).

Inclusion criteria

Key Inclusion Criteria: * Participant must have a diagnosis of MS * Documentation that the participant was one of the following: 1. exposed to DRF at any time from 2 weeks after the first day of their LMP (i.e., conception date) up through any time during pregnancy. (If exact exposure dates are unknown, the reporter must be able to specify or estimate trimester of exposure). 2. unexposed to any DMT during pregnancy, defined as having never received DMT therapy; discontinued treatment with DRF at least 1 day before 2 weeks after the first day of their LMP (i.e., conception date); or discontinued a non Registry-specified MS DMT more than 5 times its half-life prior to 2 weeks after the first day of their LMP (i.e., conception date) * Participants with knowledge of the outcome of the pregnancy (e.g., pregnancy loss or live birth) Key

Design outcomes

Primary

MeasureTime frameDescription
Number of Major Congenital Malformations (MCMs)Up to 52 weeks postdeliveryMCMs include abnormalities in structural development that are medically or cosmetically significant are present at birth, and persist in postnatal life unless or until repaired as evaluated by independent advisors used throughout the registry.

Secondary

MeasureTime frameDescription
Number of Molar PregnanciesUp to 9 months of pregnancy
Number of Elective or Therapeutic TerminationsUp to 9 months of pregnancyElective or therapeutic pregnancy termination is any induced or voluntary fetal loss during pregnancy. It will be subclassified as elective or therapeutic pregnancy terminations as whether it was due to a fatal anomaly or not.
Number of Spontaneous AbortionsBefore 22 weeks of gestationSpontaneous abortion is defined as any loss of a fetus due to natural causes before 22 weeks of gestation.
Number of Fetal Deaths Including Still BirthAt or after 22 weeks of gestationFetal death or stillbirth refers to the death of a fetus prior to complete expulsion or extraction from its mother at or after 22 weeks of gestation. Death is indicated by the fact that, after such separation, the fetus does not show any evidence of life (e.g., heartbeat, umbilical cord pulsation, or definite movement of voluntary muscles). Fetal death occurring at or after 22 weeks but before 28 weeks of gestation is considered an early fetal loss. Fetal death occurring at or after 28 weeks is considered a late fetal loss.
Number of Live BirthsUp to delivery (approximately 10 months)A live birth refers to a complete expulsion or extraction from its mother of a surviving neonate breathing, or showing any other evidence of life, such as heartbeat, umbilical cord pulsation, or definite movement of voluntary muscles, whether the umbilical cord has been cut or the placenta is attached. Any live birth before 37 weeks of gestation will be considered premature birth. Any live birth at or after 37 weeks but before 42 weeks of gestation will be considered full-term birth. Any live birth at or after 42 weeks of gestation will be considered post-term birth.
Number of Maternal DeathsUp to 12 weeks postdeliveryMaternal death is death of a pregnant woman during pregnancy, labor, or delivery. Registry will also report maternal deaths that occur up to 12 weeks postdelivery.
Number of Ectopic PregnanciesUp to 9 months of pregnancy
Number of Perinatal DeathsAt or after 28 days to 12 weeks postdeliveryPerinatal death is death occurring at or after 28 days of life and prior to 12 weeks of life.
Number of Infant DeathsBetween 12 to 52 weeks postdeliveryInfant death is death occurring between 12 and 52 weeks of life, inclusive.
Number of Serious or Opportunistic Infections in Liveborn ChildrenUp to 52 weeks postdelivery
Number of Infants with Abnormal Postnatal Growth and DevelopmentUp to 52 weeks postdeliveryInfant growth measurements will be used to estimate gender-specific weight-for-length, head circumference-for-age, length-for-age, and weight-for-age percentiles. Developmental milestones (i.e., social/emotional, language/communication, neurocognitive, movement/physical development) will be used to determine results of infant status (i.e., below, above, or at age-appropriate achievement).
Number of Participants with Pregnancy ComplicationsUp to 9 months of pregnancyPregnancy complications may include incidences of pre-eclampsia, eclampsia, pregnancy-induced hypertension, preterm labor, gestational diabetes and placenta previa.
Number of Neonatal DeathsPrior to 28 days postdeliveryNeonatal death is death occurring in a neonate prior to 28 days of life.
