Conditions
Multiple Sclerosis
Interventions
Registration Number
NCT05658497
Lead Sponsor
Biogen
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
  • 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).

Primary Outcome Measures
NameTimeMethod
Number of Major Congenital Malformations (MCMs)Up to 52 weeks postdelivery

MCMs 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 Outcome Measures
NameTimeMethod
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 postdelivery

Maternal 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 Neonatal DeathsPrior to 28 days postdelivery

Neonatal death is death occurring in a neonate prior to 28 days of life.

Number of Elective or Therapeutic TerminationsUp to 9 months of pregnancy

Elective 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 gestation

Spontaneous 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 gestation

Fetal 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 Ectopic PregnanciesUp to 9 months of pregnancy
Number of Serious or Opportunistic Infections in Liveborn ChildrenUp to 52 weeks postdelivery
Number of Perinatal DeathsAt or after 28 days to 12 weeks postdelivery

Perinatal death is death occurring at or after 28 days of life and prior to 12 weeks of life.

Number of Infants with Abnormal Postnatal Growth and DevelopmentUp to 52 weeks postdelivery

Infant 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 Molar PregnanciesUp to 9 months of pregnancy
Number of Infant DeathsBetween 12 to 52 weeks postdelivery

Infant death is death occurring between 12 and 52 weeks of life, inclusive.

Number of Participants with Pregnancy ComplicationsUp to 9 months of pregnancy

Pregnancy complications may include incidences of pre-eclampsia, eclampsia, pregnancy-induced hypertension, preterm labor, gestational diabetes and placenta previa.
