Is UNII-3A189DH42V Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use UNII-3A189DH42V? Is UNII-3A189DH42V safe for nursing mother and child? Does UNII-3A189DH42V extracts into breast milk? Does UNII-3A189DH42V has any long term or short term side effects on infants? Can UNII-3A189DH42V influence milk supply or can UNII-3A189DH42V decrease milk supply in lactating mothers?

IgG-monoclonal antibody that targets leukemic cells receptors. Use for Esclerosis Multiple has been approved. Because a high molecular weight excretion into breast milk is unlikely and destruction of protein structure in infant's bowel renders intestinal absorption nil. It should be avoid in the first two post-partum weeks since pass of significant amounts of IgG to the milk can occur in the first 3 - 4 post-partum days.

No information is available on the clinical use of UNII-3A189DH42V during breastfeeding. Because UNII-3A189DH42V is a large protein molecule with a molecular weight of 145,454, 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, UNII-3A189DH42V should be used with caution or avoided during breastfeeding, especially while nursing a newborn or preterm infant.[1][2][3] The manufacturer recommends that breastfeeding be discontinued during UNII-3A189DH42V therapy.
