Is Trogarzo safe to use while pregnant or breastfeeding?

  • Based on animal data, ibalizumab-uiyk use during pregnancy may cause reversible immunosuppression (CD4+ T cell and B cell lymphocytopenia) in infants exposed to ibalizumab-uiyk in utero.
  • Immunoglobulin G (IgG) antibodies, such as ibalizumab-uiyk, are transported across the placenta in significant amounts, especially near term; therefore, ibalizumab-uiyk has the potential to be transferred from the mother to the developing fetus.
  • There are no available data on ibalizumab-uiyk use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes.
  • The Centers for Disease Control and Prevention recommend that HIV-1-infected mothers in the United States not breastfeed their infants to avoid the risk of postnatal transmission of HIV-1 infection.
  • No data are available regarding the presence of Trogarzo in human milk, the effects on the breastfed child, or the effects on milk production.
  • Human IgG 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.
  • Because of the potential for HIV-1 transmission, instruct mothers not to breastfeed if they are receiving Trogarzo.
