Brief Summary:
The purpose of this study is to compare two different anti-HIV drug combinations, one that contains nelfinavir (NFV) and one that does not. The best dosing schedule for indinavir (IDV) also will be studied.

Condition or disease Intervention/treatment Phase
HIV Infections Drug: Indinavir sulfate Drug: Nelfinavir mesylate Drug: Lamivudine Drug: Stavudine Not Applicable

Detailed Description:
Patients are stratified by screening plasma viral RNA results (50,000 copies/ml or below vs above 50,000 copies/ml) and randomized to 1 of 2 treatment arms. Group 1 receives IDV 3 times daily plus d4T/3TC twice daily. Group 2 receives IDV/NFV/d4T/3TC twice daily. Patients remain on study medications for 24 weeks and are seen at the clinic once every 4 weeks after entering the study. At each clinic visit, blood samples are taken to evaluate CD4 cell count and plasma HIV RNA levels.

Study Type : Interventional  (Clinical Trial)
Enrollment : 220 participants
Primary Purpose: Treatment
Official Title: A Multicenter, Open-Label, 24-Week Study to Compare the Safety and Activity of Indinavir Sulfate/d4T/3TC Versus Indinavir Sulfate/Nelfinavir Mesylate/d4T/3TC in HIV-Infected Individuals
