Sponsored by Gilead Sciences · Phase 3, Interventional, and Treatment
The primary objective of this study is to evaluate the efficacy of a regimen containing elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) in HIV-1 infected, antiretroviral treatment-naive adult women.
4,258 studies on the registry are indexed under HIV Infections; 240 are open to participants now.
This study's enrollment of 583 is above the median of 83 across 3,251 interventional studies indexed under HIV Infections.

After 48 weeks of blinded treatment, participants will continue to take blinded study drug for 12 weeks and return for an unblinding visit at Week 60. Participants who are virologically suppressed at Week 48 during the double-blinded treatment phase will have the option to enter the open-label extension phase. Participants randomized to the E/C/F/TDF arm will continue to receive open-label E/C/F/TDF and participants randomized to the ATV+ RTV + FTC/TDF arm will be re-randomized to receive either open-label elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) or open-label ATV + RTV+ FTC/TDF.

Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 of the Double-Blind Phase as Determined by the US FDA-Defined Snapshot Algorithm
The percentage of participants with HIV-1 RNA \< 50 copies/mL at Week 48 of the double-blind phase was analyzed using the snapshot algorithm, which defines a participant's virologic response status using only the viral load at the predefined time point within an allowed window of time, along with study drug discontinuation status.
