An Observational Study on Teriflunomide-exposed Pregnancies

Brief description of study

Primary Objective:

To evaluate any potential increase in the risk of major birth defects, in the first year of life, in teriflunomide-exposed pregnancies.

Secondary Objective:

To evaluate the potential effect of teriflunomide-exposure on other adverse pregnancy outcomes including any potential pattern of minor birth defects, spontaneous abortion, stillbirth, preterm delivery, small for gestational age at birth and at 1 year follow-up.

The total study duration per participant is approximately up to 2 years.

  • This is a prospective, observational study (no intervention), ie, patient registry.
  • The statistical analysis for the cohort study describe baseline characteristics in all three cohorts, and then will compare pregnancy outcomes in cohort 1 to cohort 2 and secondarily to cohort 3.
  • For the "registry" group, without comparisons, only descriptive statistics of pregnancy outcomes will be summarized.

Clinical Study Identifier: NCT03198351

You may be eligible for this study if you meet the following criteria:

  • Conditions: Multiple Sclerosis
  • Age: 16 Years
  • Gender: Female

Inclusion criteria :

  • Pregnant women who have provided an oral and/or written consent to enroll no later than 20 completed weeks from last menstrual period (LMP).
  • Pregnant women who agree to the conditions and requirements of the study including the interview schedule, release of medical records, and the physical examination of live born infants (up to 1 year post birth).
  • Pregnant women with a diagnosis of MS and teriflunomide exposure during pregnancy (Cohort 1).
  • Pregnant women with MS but not exposed teriflunomide during pregnancy (Cohort 2).
  • Healthy pregnant women who do not have a known diagnosis of MS and have no known exposure to a known human teratogen during pregnancy (Cohort 3).

Exclusion criteria:

  • Pregnant women who come in first contact with the project after prenatal diagnosis of a major structural defect (Cohort 1, 2, 3). This does not apply to the "registry" group.
  • Pregnant women who first come in contact with the project after 20 completed weeks' gestation (Cohort 1, 2, 3). This does not apply to the "registry" group.
  • Pregnant women who had previously enrolled in the study for a previous pregnancy (only 1 pregnancy, per woman, maybe registered) (Cohort 1, 2, 3). This does not apply to the "registry" group.
  • Retrospectively reported cases (Cohort 1, 2, 3). This does not apply to the "registry" group.
  • Pregnant women with exposures to teriflunomide commencing after the 12th week post-LMP (Cohort 1). This does not apply to the "registry" group.
  • Pregnant women who had previously been treated with teriflunomide if they had received any dose of the drug within 2 years prior to the index pregnancy and do not have documented blood levels below 0.02 mcg/mL prior to pregnancy (Cohort 2).
        The above information is not intended to contain all considerations relevant to a patient's
        potential participation in a clinical trial.
