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

This study is to evaluate the efficacy darunavir/cobicistat/emtricitabine/GS-7340 (D/C/F/TAF) single-tablet regimen (STR) versus darunavir (DRV)+cobicistat (COBI)+emtricitabine(FTC)/tenofuvir disoproxil fumarate (TDF) in HIV-1 infected, antiretroviral treatment-naive adults as determined by the achievement of HIV-1 RNA < 50 copies/mL at Week 24.
