GS-US-292-0111: A Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of Elvitegravir/Cobicistat/Emtricitabine/ Tenofovir Alafenamide Versus Elvitegravir/Cobicistat/ Emtricitabine/Tenofovir Disoproxil Fumarate in HIV-1 Positive, Antiretroviral Treatment-Naïve Adults

Description

This study will evaluate the efficacy and safety of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (Genvoya®; E/C/F/TAF) fixed-dose combination (FDC) versus elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (Stribild®; E/C/F/TDF) in HIV-1 positive, antiretroviral treatment-naive adults.

Phase

Phase 3 - a treatment has shown activity against a particular disease, where it is either added to existing treatment or compared to the standard treatment.
