A Study of Zidovudine in HIV-Infected Pregnant Women and Their Children
Completed · Phase 1
Conditions studied: HIV Infections, Pregnancy
In brief
AMENDED: To evaluate the pharmacokinetics of intravenously administered AZT to HIV-1 infected pregnant women in labor; to evaluate the pharmacokinetics and urinary excretion of AZT and its metabolites in newborns of HIV-1 infected mothers who receive IV AZT only during labor; to evaluate the safety of IV AZT administered by continuous infusion to HIV-1 infected laboring women and their infants. Original design: To determine the distribution and elimination of zidovudine (AZT) in the body as well as its safety in the treatment of pregnant women and their unborn children. The information derived from this study is required in order to design a future study that will assess the efficacy of AZT in reducing the transmission rate of HIV-1 from seropositive women to their fetus by treating them during the third trimester of pregnancy. An estimated 30 percent to 40 percent infected pregnant women risk transmission of HIV-1 to their infants, whether they be symptomatic or asymptomatic. Zidovudine (AZT) has previously demonstrated its effectiveness as a potent inhibitor of HIV replication in vitro and in adult patients; benefits of treatment include decreased mortality rate, decreased incidence of opportunistic infections, and increased number of CD4 cells. Phase I AZT studies in children, however, have resulted in uncontrolled information regarding clinical efficacy. The present study, therefore, will investigate the safety and pharmacokinetics of intravenous (IV) and oral AZT administration to HIV-1 infected pregnant women in the 3rd trimester, as well as the safety and efficacy of such treatment in their newborns. It is hoped that the results will be instrumental in designing future studies to assess the efficacy of AZT in reducing the transmission risk of HIV-1.
