Who may not be able to join:
Cohort 1 – Kesimpta-Exposed Group:
- Women who previously enrolled in this Kesimpta study during an earlier pregnancy
- Women who used Kesimpta for a reason other than an officially approved medical use
- Women who were exposed to certain other MS medications close to the time of conception, including other anti-CD20 antibody medications (same drug class as Kesimpta), S1P modulator medications (same drug class as Mayzent), Cladribine (Mavenclad), or Teriflunomide (Aubagio) — newer MS medications approved after 2021 will be assessed on a case-by-case basis as the study progresses (confirm with trial site)
- Women who have already had their pregnancy end before enrolling in the study

- Women who were exposed close to conception to certain MS medications, including anti-CD20 antibody drugs, Cladribine (Mavenclad), S1P modulator drugs, or Teriflunomide (Aubagio) — newer MS medications approved after 2021 will be assessed as the study progresses (confirm with trial site)
- Women who previously enrolled in this Kesimpta study or the related Mayzent (BAF312A2403) study during an earlier pregnancy
- Women who have already had their pregnancy end before enrolling in the study
- Women whose prenatal tests have already confirmed a major structural birth defect in the baby — women with other prenatal test results, whether normal or showing other findings, may still be considered as long as no major structural defect has been confirmed
Cohort 3 – Healthy Comparison Group (sub-study only):
- Women who received Kesimpta from around 166 days before their last menstrual period, or Mayzent from 4 days after their last menstrual period, or either medication at any point during the current pregnancy
- Women who have a diagnosis of MS
- Women who have a current diagnosis of any autoimmune disease
- Women who first contacted the study team after a prenatal diagnosis of a major structural birth defect was made
- Women who used Mayzent or Kesimpta for a reason other than treating MS
- Women who have already had their pregnancy end before enrolling in the study
- Women whose prenatal tests have already confirmed a major structural birth defect in the baby — women with other prenatal test results, whether normal or showing other findings, may still be considered as long as no major structural defect has been confirmed
