ClinConnect Summary
The Kesimpta Pregnancy Registry is a study designed to learn about the effects of the medication Kesimpta (ofatumumab) on pregnant women with multiple sclerosis (MS) and their babies. The goal is to understand how exposure to Kesimpta during pregnancy might affect both pregnancy outcomes and the health of infants. The study is currently recruiting participants who are pregnant and have a confirmed MS diagnosis. Eligible women can be those who have taken Kesimpta at any time from about five months before pregnancy through delivery, or those who have not taken any MS medications during their pregnancy.
Participants in the study will be asked to share information about their health and their pregnancy. This includes interviews, allowing researchers to access medical records, and having their babies examined for any birth defects. If you are a pregnant woman diagnosed with MS or a healthy pregnant woman willing to contribute to this important research, you may qualify for this study. Your involvement could help improve understanding of MS treatment during pregnancy and guide future care for women in similar situations.

Eligibility criteria
- Inclusion Criteria:
- Participants must meet all the criteria listed under the respective cohorts to enroll in that particular cohort of the registry:
- • Cohort 1: Kesimpta-Exposed Cohort
- • 1. Pregnant women
- • 2. Diagnosed with MS, with the indication validated by medical records when possible
- • 3. Administered Kesimpta for the treatment of MS at any time from 166 days prior to the first day of the LMP, or up to and including the end of pregnancy
- • 4. Agree to the conditions and requirements of the study including the interview schedule, release of medical records, the dysmorphology examination of live born infants (OTIS specific), and validated developmental performance questionnaire in live born children
- • Cohort 2: Disease-Matched Comparison Cohort (Comparison Group 1)
- • 1. Pregnant women
- • 2. Diagnosed with MS, with the indication validated by medical records when possible
- • 3. May or may not have taken another medication for MS in the current pregnancy
- • 4. Agree to the conditions and requirements of the study including the interview schedule, release of medical records, the dysmorphology examination of live born infants (OTIS specific), and validated developmental performance questionnaire in live born children
- • Cohort 3: Healthy Comparison Cohort (Comparison Group 2):Kesimpta-OTIS sub-study specific
- • 1. Pregnant women
- • 2. Agree to the conditions and requirements of the study including the interview schedule, release of medical records, the dysmorphology examination of live born infants, and validated developmental performance questionnaire in live born children
- Exclusion Criteria:

- • Cohort 1: Kesimpta-Exposed Cohort
- • 1. Women who have enrolled in the Kesimpta cohort study with a previous pregnancy
- • 2. Women who have used Kesimpta for an indication other than a currently approved indication
- 3. Women with exposure to any of the following medications within 5 half-lives (or pharmacodynamic effect when relevant) prior to conception:
- • Other anti-CD20 monoclonal antibody: same class as Kesimpta
- • S1P modulators: same class as Mayzent
- • Cladribine (Mavenclad): Based on the US label, animal studies indicate that there is positive evidence of teratogenicity for Cladribine
- • Teriflunomide (Aubagio): The teratogenecity of teriflunomide is unknown and currently under investigation.
- • New medications (marketed after 2021) indicated for the treatment of MS will be evaluated for inclusion/exclusion criteria as the study progresses.
- • 4. Retrospective enrollment after the outcome of pregnancy is known (i.e. the pregnancy has ended prior to enrollment)
- • 5. Results of diagnostic test(s) that are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect.
- • Cohort 2: Disease-Matched Comparison Cohort (Comparison Group 1)
- • 1. Administered Kesimpta 166 days before the first day of LMP or anytime during pregnancy
- 2. Women with exposure to any of the following medications within 5 half-lives (or pharmacodynamic effect when relevant) of conception:
- • Anti CD-20 monoclonal antibody
- • Cladribine (Mavenclad)
- • S1P modulators
- • Teriflunomide (Aubagio) New medications (marketed after 2021) indicated for the treatment of MS will be evaluated for inclusion/exclusion criteria as the study progresses.
- • 3. Women who have enrolled in the Kesimpta cohort or BAF312A2403 Mayzent cohort with a previous pregnancy
- • 4. Retrospective enrollment after the outcome of pregnancy is known (i.e. the pregnancy has ended prior to enrollment)
- • 5. Results of diagnostic test(s) that are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect.
- • Cohort 3: Healthy Comparison Cohort (Comparison Group 2): Only applicable to Kesimpta-OTIS sub-study
- • 1. Administered Kesimpta 166 days before or Mayzent 4 days after the first day of LMP or anytime during pregnancy
- • 2. Women who have a diagnosis of a MS
- • 3. Women who have a current diagnosis of any autoimmune disease
- • 4. Women who have first contact with the project after prenatal diagnosis of any major structural defect
- • 5. Women treated with Mayzent or Kesimpta for non-MS indication
- • 6. Retrospective enrollment after the outcome of pregnancy is known (i.e. the pregnancy has ended prior to enrollment)
- • 7. Results of diagnostic test(s) that are positive for a major structural defect prior to enrollment. However, women who have had any normal or abnormal prenatal screening or diagnostic test prior to enrollment are eligible as long as the test result does not indicate a major structural defect.
- • 8. Women exposed to a known human teratogenic drugs during pregnancy
