A Phase I Trial to Evaluate Didanosine (ddI) in HIV-Infected Pregnant Women

27. oktober 2021 opdateret af: National Institute of Allergy and Infectious Diseases (NIAID)

To assess the pharmacokinetics, safety, and toxicity of intravenous and oral didanosine (ddI) administration in third trimester pregnant women who are HIV positive but are either intolerant or resistant to zidovudine (AZT). To collect data on infant toxicity following maternal treatment with ddI during the third trimester of pregnancy.

AZT may not be the optimal antiretroviral agent for all pregnant women requiring therapy for HIV infection. Although ddI has been approved for use in HIV-infected adults and older children, the safety and pharmacokinetics of ddI in pregnant women has not yet been determined.

Detaljeret beskrivelse

AZT may not be the optimal antiretroviral agent for all pregnant women requiring therapy for HIV infection. Although ddI has been approved for use in HIV-infected adults and older children, the safety and pharmacokinetics of ddI in pregnant women has not yet been determined.

Patients receive a single IV dose of ddI on day 1 and pharmacokinetics values are determined. At least 48 hours but no more than 1 week after the IV dose, patients receive an oral dose, and oral pharmacokinetics are obtained for 8 hours. Oral ddI is then administered every 12 hours until labor commences and then after delivery, every 12 hours until 6 weeks postpartum. During labor and delivery, patients receive a loading dose of ddI followed by continuous infusion. Pharmacokinetics are obtained during infusion and also at 6 weeks postpartum. AS PER AMENDMENT 11/24/97: Maternal IV pharmacokinetic studies will not be performed after ddI IV formulation has expired (11/30/97). Maternal and cord samples will be required regardless of whether mother has received continuous IV ddI during labor.
