Trial Summary
This study will evaluate the potential placental transfer of ocrelizumab in women with clinically isolated syndrome (CIS) or multiple sclerosis (MS) [in line with the locally approved indications] whose last dose of ocrelizumab was administered any time from 6 months before the last menstrual period (LMP) through to the first trimester (up to gestational week 13) of pregnancy, and the corresponding pharmacodynamic effects (B cell levels) in the infant.
A Phase IV Multicenter, Open-Label Study Evaluating B Cell Levels In Infants Potentially Exposed To Ocrelizumab During Pregnancy
Eligibility Criteria
- Diagnosis of MS or CIS (in line with the locally approved indications)
- Currently pregnant with singleton pregnancy at gestational week ≤30 at enrolment
- Documentation that first and second obstetric ultrasound has been conducted before enrolment during the screening period
- Documentation that the last exposure to ocrelizumab occurred up to 6 months before the LMP before the woman became pregnant OR during the first trimester of pregnancy
- Last exposure to ocrelizumab >6 months before the woman's LMP or later than the first trimester of pregnancy
- Gestational age at enrolment >30 weeks
- Non-singleton pregnancy
- Received the last dose of ocrelizumab at a different posology other than per the local prescribing information
- Lack of access to ultrasound pre-natal care as part of standard clinical practice
- Prior or current obstetric/gynecological conditions associated with adverse pregnancy outcomes
- Pre-pregnancy body mass index >35 kg/m2
- Any concomitant disease that may require chronic treatment with systemic corticosteroids or immunosuppressants during the course of the study
- Prior or current history of primary or secondary immunodeficiency, or woman in an otherwise severely immunocompromised state
- Significant and uncontrolled disease that may preclude a woman from participating in the study
- Women with known active malignancies or being actively monitored for recurrence of malignancy including solid tumors and hematological malignancies
- Prior or current history of alcohol or drug abuse, or current use of tobacco
- Positive screening tests for hepatitis B
- Treatment with drugs known to have teratogenic effects
- Planned treatment with interferons, glatiramer acetate, or pulsed corticosteroids as a bridging therapy after the last ocrelizumab dose and throughout pregnancy
- Treatment with disease-modifying therapies for MS within their respective half-lives prior to the last ocrelizumab dose or prior to the LMP
- Treatment with natalizumab within 12 weeks prior to the LMP
- Treatment with teriflunomide within the last two years, unless measured plasma concentrations are <0.02 mg/L. If levels are >0.02 mg/L or not known, an accelerated elimination procedure is required
- Treatment with any investigational agent within 6 months or five half-lives of the investigational drug prior to the last ocrelizumab dose or prior to the LMP
