Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of GS-9350-boosted Atazanavir Versus Ritonavir-boosted Atazanavir Each Administered With Emtricitabine/Tenofovir Disoproxil Fumarate in HIV-1 Infected, Antiretroviral Treatment-Naïve Adults
A Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of GS-9350-boosted Atazanavir Versus Ritonavir-boosted Atazanavir Each Administered With Emtricitabine/Tenofovir Disoproxil Fumarate in HIV-1 Infected, Antiretroviral Treatment-Naïve Adults

To evaluate the safety and efficacy of a regimen containing GS-9350-boosted atazanavir plus emtricitabine/tenofovir disoproxil fumarate versus ritonavir-boosted atazanavir plus emtricitabine/tenofovir disoproxil fumarate in HIV 1 infected, antiretroviral treatment-naïve adults. Development of GS-9350 as a "pharmacoenhancer" could provide a beneficial alternative to ritonavir for use in combination with protease inhibitors.
