Sacituzumab Govitecan Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of sacituzumab govitecan during breastfeeding. Because sacituzumab is a large protein molecule, the amount in milk is likely to be very low.[1] It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal.[2] Govitecan is a small-molecule anticancer drug that might enter milk and be absorbed by the infant. Because of the potential for serious adverse reactions in the breastfed infant, the manufacturer recommends that women not breastfeed during treatment and for at least 1 month after the final dose.
