Clinical Trial Summary

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.

Description:

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.

• IV AZT during labor.

Patients must have:

• HIV infection.
• CD4 count > 50 and < 350 cells/mm3.
• AZT intolerance or resistance.
• Gestational age at least 26 weeks but not more than 36 weeks.
• Consent of guardian if necessary. The father of the fetus must also provide consent if available after reasonable attempts have been made to contact him. Exclusion Criteria Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

• No access to a participating ACTU. Concurrent Medication:

Excluded:

• Drugs that might aggravate pancreatitis, such as steroids, isoniazid, and parenteral pentamidine.
• Antiretrovirals other than ddI (although IV AZT is allowed during labor).

Patients with the following prior conditions are excluded:

• History of stillbirth, neonatal loss, or previous infant with anomaly (history of preeclampsia or preterm labor is permitted).
• History of maternal medical complications including but not limited to malabsorption syndrome, pancreatitis, neurological complications including grade 2 or worse peripheral neuropathy, symptomatic cholelithiasis, or prior active CMV disease requiring ganciclovir or foscarnet.
• History of poor medical compliance not related to access to medical care. Prior Medication:

Excluded:

• ddI within 24 hours prior to study entry.
