A Phase 2, Randomized, Double-Blinded Study of the Safety and Efficacy of Elvitegravir/Cobicistat/Emtricitabine/GS-7340 Single Tablet Regimen Versus Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Disoproxil Fumarate Single Tablet Regimen in HIV 1 Infected, Antiretroviral Treatment-Naive Adults

This study is to evaluate the safety, efficacy, and tolerability of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) single tablet regimen (STR) versus E/C/F/tenofovir disoproxil fumarate (TDF; E/C/F/TDF) STR in HIV-1 infected, antiretroviral treatment-naive adults as determined by the achievement of HIV-1 RNA < 50 copies/mL at Week 24.
