Pregnancy & Breastfeeding
8.1 Pregnancy Risk Summary Adequate and well-controlled studies with REVCOVI have not been conducted in pregnant women to inform a drug-associated risk. Animal reproduction studies have not been conducted with REVCOVI. It is not known whether REVCOVI can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. All pregnancies have a risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Human No pregnancy was reported for any patients receiving REVCOVI. There are two reports of confirmed cases of successful pregnancy and delivery in ADA-SCID patients treated with Adagen (the same class of enzyme replacement therapy used in the treatment of ADA-SCID). No teratogenic effects of Adagen were reported. For patients treated with REVCOVI, more frequent monitoring of the health status for both the mother during pregnancy and the development of the offspring is recommended.
