A Study of 1592U89 in Combination With Protease Inhibitors in HIV-Infected Patients Who Have Never Taken Anti-HIV Drugs

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to see if it is safe and effective to give 1592U89 plus certain protease inhibitors (PIs) to HIV-infected patients who never have been treated with anti-HIV drugs. This study also examines how the body processes these drugs when they are given together.

Detailed Description
-----------------
In this Phase II, open-label study patients (16 per treatment group) are randomized to receive 1592U89 in combination with one of five protease inhibitors: indinavir, saquinavir, ritonavir, nelfinavir, or 141W94 for up to 48 weeks.

Official Title
-----------------
An Open-Label, Phase II Trial to Evaluate the Steady-State Pharmacokinetics, Safety, and Efficacy of 1592U89 in Combination With Selected HIV-1 Protease Inhibitors in Antiretroviral-Naive, HIV-1-Infected Patients.

Intervention / Treatment
-----------------
* Drug: Indinavir sulfate

Immunomodulating agents such as systemic corticosteroids, interleukins, thalidomide, anti-cytokine agents or interferons. Antioxidants. Concurrent Treatment: Excluded: Radiation therapy within the first 24 weeks of study. Patients with the following prior conditions are excluded: History of clinically relevant pancreatitis or hepatitis within the last 6 months. Participation in an investigational HIV-1 vaccine trial. Prior Medication: Excluded: Antiretroviral therapy, including reverse transcriptase inhibitor and protease inhibitor therapy. Cytotoxic chemotherapeutic agents within 30 days of study drug administration. HIV-1 vaccine dose within the 3 months prior to study drug administration. Immunomodulating agents, such as systemic corticosteroids, interleukins or interferons within 30 days of study drug administration. Prior Treatment: Excluded: Radiation therapy within 30 days of study drug administration. Alcohol or illicit drug use that may interfere with patient compliance.
