Drug Levels and Effects
Summary of Use during Lactation
No information is available on the clinical use of moxetumomab pasudotox during breastfeeding. Moxetumomab pasudotox is a recombinant immunotoxin consisting of the Fv portion of the anti-CD22 antibody covalently fused to a 38 KDa fragment of Pseudomonas exotoxin-A (PE38) with potential anti-cancer activity. Because moxetumomab is a large protein molecule with a molecular weight of about 63,000 Da, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. Until more data become available, moxetumomab pasudotox should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant.
