Is MEDI 4736 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use MEDI 4736? Is MEDI 4736 safe for nursing mother and child? Does MEDI 4736 extracts into breast milk? Does MEDI 4736 has any long term or short term side effects on infants? Can MEDI 4736 influence milk supply or can MEDI 4736 decrease milk supply in lactating mothers?

No information is available on the clinical use of MEDI 4736 during breastfeeding. Because MEDI 4736 is a large protein molecule with a molecular weight of about 146,000, 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, MEDI 4736 should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. The manufacturer recommends that mothers not breastfeed during treatment and for at least 3 months after the last dose of MEDI 4736. MEDI 4736 is a human immunoglobulin G1 (IgG1) kappa antibody. Holder pasteurization (62.5 degrees C for 30 minutes) decreases the concentration of endogenous immunoglobulin G by up to 79%.[1][2] A study of 67 colostrum samples that underwent Holder pasteurization found that IgG amounts decreased by 34 to 40%. Specific IgG subclasses decreased by different amounts, with IgG1 activity decreasing by about 37%.[3] None of the studies measured IgG activity.
