Entry and Attachment Inhibitors
Ibalizumab-uiyk (Trogarzo, IBA)
Animal studies
Carcinogenicity
Carcinogenicity and mutagenicity studies of ibalizumab-uiyk (IBA) have not been conducted.1
Reproduction/Fertility
Reproductive toxicology studies of IBA have not been conducted.1
Teratogenicity/Adverse Pregnancy Outcomes
Early embryonic development and embryo-fetal development studies with IBA have not been conducted.
Placental and Breast Milk Passage
No data are available on placental or breast milk passage of IBA in animals.
Human Studies in Pregnancy
Pharmacokinetics
No pharmacokinetic studies of IBA in pregnant women have been reported.
Placental and Breast Milk Passage
No data are available on placental or breast milk passage of IBA in humans. However, because monoclonal antibodies are transported across the placenta during pregnancy, IBA has the potential to be transmitted from the mother to the developing fetus. Human immunoglobulin G also is present in human milk, although published data indicate that antibodies in breast milk do not enter the neonatal or infant circulation system in substantial amounts.1
Teratogenicity/Adverse Pregnancy Outcomes
No data are currently available on the risk of birth defects in infants born to women who received IBA during pregnancy.
