Amivantamab Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the clinical use of amivantamab during breastfeeding. Because amivantamab is a large protein molecule with a molecular weight of 148,000 Da, the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. The manufacturer recommends avoiding breastfeeding during amivantamab use and for 3 months after the last dose.
