Is BIW 8405 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use BIW 8405? Is BIW 8405 safe for nursing mother and child? Does BIW 8405 extracts into breast milk? Does BIW 8405 has any long term or short term side effects on infants? Can BIW 8405 influence milk supply or can BIW 8405 decrease milk supply in lactating mothers?

No information is available on the clinical use of BIW 8405 during breastfeeding. Because BIW 8405 is a large protein molecule with a molecular weight of about 150,000, 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, BIW 8405 should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. BIW 8405 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.
