Safety and Efficacy of COBI-boosted Atazanavir Versus Ritonavir-boosted Atazanavir Each Administered With Emtricitabine/Tenofovir Disoproxil Fumarate in HIV-1 Infected, Antiretroviral Treatment-Naive Adults

Summary

The objective of this study is to evaluate the safety and efficacy of a regimen containing cobicistat-boosted atazanavir (ATV+COBI) plus emtricitabine/tenofovir disoproxil fumarate (Truvada®; FTC/TDF) fixed-dose combination (FDC) versus ritonavir-boosted atazanavir (ATV+RTV) plus FTC/TDF FDC in HIV-1 infected, antiretroviral treatment-naive adults. Participants will be randomized in a 1:1 ratio. Randomization will be stratified by HIV-1 RNA level (≤ 100,000 copies/mL or \> 100,000 copies/mL) at screening.
