11. Scope of the study
What is the scope of the study?
Risk assessment
Primary scope : Risk assessment
12. Main objective(s)
What is the main objective of the study?
To estimate the frequency of pregnancy and infant outcomes in women with MS exposed to ocrelizumab in the 6 months before conception or during pregnancy. To compare the frequency of pregnancy and infant outcomes in the exposed cohort with that in pregnant women with MS unexposed to ocrelizumab (primary comparator) and pregnant women without MS unexposed to ocrelizumab (secondary comparator).
Are there primary outcomes?Yes
Spontaneous abortion, stillbirth, elective termination, preterm delivery, C-section, antenatal urinary tract infections, antenatal infections requiring hospitalization, major congenital malformations, minor malformations (to the extent available), small for gestational age, adverse effects on the infant immune system, infant growth and development (to the extent available)
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cohort study
Observational study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
Follow-up of women will start at the beginning of pregnancy and will finish at the end of pregnancy; follow-up of infants will start at birth and finish at 1 year of age. For mothers and infants, follow-up will end at the earliest of death, disenrollment, or end of the study period. For each outcome that can occur multiple times, follow-up for that outcome will stop at its first occurrence.
15. Data analysis plan
Please provide a brief summary of the analysis method
Characteristics of the unmatched and matched cohorts, including frequency of outcomes, will be output. Balance in matching will be assessed by examining the distribution of variables in the cohorts and estimating standardized differences for each variable between the ocrelizumab-exposed and comparator cohorts. Variables with standardized differences above 0.1 will be further evaluated and may lead to a re-evaluation of the propensity score estimation.
Unadjusted measures of outcome frequency will be estimated within the matched cohorts. Measures of association will vary across outcomes and include incidence rate ratios and odds ratios. No adjustment is planned beyond matching. Subgroup analyses will include strata of maternal age, calendar year, and others (depending on counts and data availability). Association results will be summarized across data sources using meta-analytic techniques with random effects.
