Evolocumab Pregnancy Warnings

In animal reproduction studies, there were no effects on pregnancy or neonatal/infant development when monkeys were subcutaneously administered this drug from organogenesis through parturition at dose exposures higher than the maximum recommended human dose. Humoral immune suppression occurred in infant monkeys exposed to others PCSK9 inhibitors antibody in the uterus at all doses. No assessment for immune suppression was conducted with this drug in infant monkeys. Measurable serum concentrations of this drug were observed in the infant monkeys at birth at comparable levels to maternal serum, indicating that this drug, like other IgG antibodies, crosses the placental barrier. Experience with monoclonal antibodies in humans indicates that they are unlikely to cross the placenta in the first trimester; however, they are likely to cross the placenta in increasing amounts in the second and third trimester. There are no available data on use of this drug in pregnant women.
