Study description

The design of this pregnancy PASS is a cohort study based on secondary use of data from various automated healthcare databases (AHDB) and registers in 6 European countries: Denmark, Finland, France, Germany, Norway, Sweden, and Scotland (United Kingdom). Women with Multiple Sclerosis (MS) who were exposed to oral cladribine during pregnancy and/or within 6 months before their last menstrual period (LMP) (i.e. exposure period, which correspond to the at-risk period for pregnancy outcomes, major congenital anomalies (MCA) in infants), or pregnancies fathered by men with MS treated with oral cladribine within 6 months before the LMP, will be identified in the selected databases/registers. Data will be retrieved on pregnancies and their outcomes, and infants for MCA, and hearing loss. Comparison of pregnancy outcomes will be conducted in pregnant women with MS between the exposed cohort (exposure to oral cladribine within the at-risk period) and the unexposed cohort (unexposed to any Disease-modifying drug [DMD] during the at-risk period, which can vary from 3 to 24 months according to the DMD) and in pregnant women whose pregnancy is fathered by men with MS between the exposed cohort (pregnancy fathered by men with MS exposed to oral cladribine within the at-risk period) and the unexposed cohort (pregnancy fathered by men with MS unexposed to any DMD during the at-risk period, which can vary from 3 to 6 months before the LMP according to the DMD . In the selected data sources, pregnancies will be followed until the outcome of the pregnancy is known, and live births resulting from an identified pregnancy will be followed for up to one year of age.
