Abstract

ObjectiveTo assess the safety profile of erenumab, galcanezumab and fremanezumab in pregnancy and lactation.MethodsSafety reports of suspected adverse drug reactions were retrieved from VigiBase as of 31 December 2019, for a case-by-case assessment and disproportionality analysis using the reporting odds ratio (ROR).ResultsThere were 94 safety reports: 50 (53.2%) on erenumab, 31 (33.0%) on galcanezumab, and 13 (13.8%) on fremanezumab. In five (5.3%) safety reports, drug exposure occurred prior to pregnancy, in 85 (90.4%) during pregnancy, in one (1.1%) during lactation, in one (1.1%) via paternal exposure, and in two (2.1%) the exposure time was unknown. Out of 94 safety reports, 51 (54.3%) consisted only of drug exposure, while 43 (45.7%) additionally reported 47 adverse drug reactions including maternal toxicities (n = 18), poor breastfeeding (n = 1), spontaneous abortion (n = 23), preterm birth/prematurity (n = 3), and birth defects (n = 2).
