A Phase III Randomized, Double-Blind, Controlled Study of the Use of Anti-HIV Immune Serum Globulin (HIVIG) for the Prevention of Maternal-Fetal HIV Transmission in Pregnant Women and Newborns Receiving Zidovudine (AZT)

To evaluate the effect of anti-HIV immune serum globulin (HIVIG) versus immune globulin (IVIG) administered during pregnancy and to the newborn, in combination with zidovudine (AZT) administered intrapartum and to the newborn, on incidence of HIV infection in infants born to HIV-infected women who received AZT during pregnancy for medical indications. Vertical transmission of HIV from mother to child may occur before, during, or after parturition (via breast-feeding). It is believed that therapy administered both during pregnancy and intrapartum may help prevent vertical transmission. Additionally, adjunctive short-term antiretroviral therapy for the newborn, following the intensive viral exposure presumed to occur at birth, may be necessary.
