Official title

A Phase III Randomized, Controlled Trial of Efavirenz (EFV) or Nelfinavir (NFV) in Combination With Fixed-Dose Combination Lamivudine/Zidovudine (3TC/ZDV) and Indinavir (IDV) in HIV-Infected Subjects With Less Than or Equal to 200 CD4 Cells/mm3 or Greater Than or Equal to 80,000 HIV RNA Copies/ml in Plasma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

To compare time to a virologic failure (first of 2 consecutive plasma HIV RNA levels greater than or equal to 200 copies/ml at or after Week 24) of each 4-drug regimen vs the 3-drug regimen. To determine the safety, tolerance, and virologic benefits of either nelfinavir (NFV) or efavirenz (EFV) with indinavir/lamivudine/zidovudine (IDV/3TC/ZDV) vs IDV/3TC/ZDV alone, in the treatment of patients with advanced HIV disease who have received limited or no prior antiretroviral therapy. Prior ACTG studies have shown that the 3-drug combination regimen (IDV/ZDV/3TC) resulted in improved clinical outcomes and therefore may prolong the effects of therapy. The enhanced effects seen with combination therapies are likely related to a greater suppression of RNA replication and alterations in resistance patterns. Due to the progressive success of combination regimens, it is possible that more potent regimens will further enhance viral suppression and provide more durable treatment responses. In light of the additive suppression of HIV replication determined by pharmacological, immunological, and virological results, nelfinavir (NFV) as an addition to IDV/ZDV/3TC will be evaluated. Based on the potency of nonnucleoside reverse transcriptase inhibitors (NNRTIs) to suppress viral replication and the effectiveness of 3-drug regimens containing NNRTIs, efavirenz (EFV) will also be evaluated as an addition to IDV/ZDV/3TC.
