Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of Stribild Versus Atripla in Human Immunodeficiency Virus, Type 1 (HIV-1) Infected, Antiretroviral Treatment-Naive Adults
To evaluate the safety and efficacy of Stribild, a single tablet regimen (STR) containing fixed doses of elvitegravir (EVG)/GS-9350 (cobicistat; COBI)/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF (Atripla) in HIV-1 infected, antiretroviral treatment-naive adults. Stribild offers an alternative STR for patients who are not candidates for non-nucleoside reverse transcriptor (NNRTI)-based STRs.

|Official Title:||A Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of Elvitegravir/Emtricitabine/Tenofovir Disoproxil Fumarate/GS-9350 Versus Efavirenz/Emtricitabine/Tenofovir Disoproxil Fumarate in HIV-1 Infected, Antiretroviral Treatment-Naive Adults|
- The Percentage of Participants With Virologic Success Using the Food and Drug Administration (FDA)-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 Ribonucleic Acid (RNA) < 50 Copies/mL [ Time Frame: Week 48 ] [ Designated as safety issue: No ]The percentage of participants with virologic success assessed using the FDA-defined snapshot analysis for an HIV-1 RNA cutoff of 50 copies/mL was summarized.
- The Percentage of Participants Achieving and Maintaining Confirmed HIV-1 RNA < 50 Copies/mL Using the FDA-defined Time to Loss of Virologic Response (TLOVR) Algorithm [ Time Frame: Week 48 ] [ Designated as safety issue: No ]The percentage of participants achieving and maintaining confirmed HIV-1 RNA < 50 copies/mL using the FDA-defined TLOVR algorithm was summarized.
- The Change From Baseline in Cluster Determinant 4 (CD4) Cell Count at Week 48 [ Time Frame: Baseline to Week 48 ] [ Designated as safety issue: No ]Change = Week 48 value minus baseline value
- The Percentage of Participants With HIV-1 RNA < 50 Copies/mL [ Time Frame: Week 48 ] [ Designated as safety issue: No ]The percentage of participants with plasma HIV-1 RNA < 50 copies/mL was summarized.
