Study summary

This study will evaluate the non-inferiority of Stribild® (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 Truvada® (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.

What researchers measure

Primary outcomes

  1. Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48

    The FDA-defined Snapshot algorithm was used, which defines a patient's virologic response status using only the viral load at the predefined time point within an allowed window of time.

    Time frame: Week 48

Secondary outcomes

  1. Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 96

    The FDA-defined Snapshot algorithm was used, which defines a patient's virologic response status using only the viral load at the predefined time point within an allowed window of time.

    Time frame: Week 96

  2. Change From Baseline in CD4+ Cell Count at Week 48

    Time frame: Baseline; Week 48
