A Phase 3b Randomized, Open-Label Study to Evaluate Switching From Regimens Consisting of a Ritonavir-boosted Protease Inhibitor (PI + RTV) Plus Emtricitabine/Tenofovir Disoproxil Fumarate (FTC/TDF) to the Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Disoproxil Fumarate Single-Tablet Regimen (EVG/COBI/FTC/TDF) in Virologically-Suppressed, HIV-1 Infected Patients

This study will evaluate the non-inferiority of StribildŽ (elvitegravir/cobicistat/ emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF)) single-tablet regimen (STR) relative to regimens consisting of a protease inhibitor (PI) boosted with ritonavir (RTV) plus TruvadaŽ (FTC/TDF) fixed-dose combination in maintaining HIV-1 RNA < 50 copies/mL at Week 48 in virologically suppressed, HIV-1 infected adults. This study will also evaluate the safety, tolerability, and efficacy of the two regimens through 96 weeks of treatment.
