Brief Summary:
To evaluate the safety and efficacy of Stribild®, a single tablet regimen (STR) containing fixed doses of elvitegravir (EVG)/cobicistat (COBI [GS-9350])/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-based STRs.

Outcome Measures

Primary Outcome Measures :
  1. 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 at Week 48 [ Time Frame: Week 48 ]

Secondary Outcome Measures :
  1. The Percentage of Participants With Virologic Success Using the FDA-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 RNA < 50 Copies/mL at Week 96 [ Time Frame: Week 96 ]
  2. The Percentage of Participants With Virologic Success Using the FDA-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 RNA < 50 Copies/mL at Week 144 [ Time Frame: Week 144 ]
  3. The Percentage of Participants With Virologic Success Using the FDA-Defined Snapshot Analysis as Determined by the Achievement of HIV-1 RNA < 50 Copies/mL at Week 192 [ Time Frame: Week 192 ]
  4. The Percentage of Participants Achieving and Maintaining Confirmed HIV-1 RNA < 50 Copies/mL at Week 48 Using the FDA-defined Time to Loss of Virologic Response (TLOVR) Algorithm [ Time Frame: Week 48 ]
  5. The Change From Baseline in Cluster Determinant 4 (CD4) Cell Count at Weeks 48, 96, 144, and 192 [ Time Frame: Baseline; Weeks 48, 96, 144, and 192 ]
    Change = value of the relevant time point minus the baseline value

  6. The Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 [ Time Frame: Week 48 ]

  • No prior use of any approved or investigational antiretroviral drug for any length of time
  • Screening genotype report must show sensitivity to FTC, TDF, and EFV
  • Normal electrocardiogram (ECG)
  • Adequate renal function (estimated glomerular filtration rate ≥ 70 mL/min according to the Cockcroft Gault formula)
  • Hepatic transaminases (aspartate aminotransferase (AST) and alanine aminotransferase (ALT)) ≤ 5 x the upper limit of the normal range (ULN)

  • Males and females of childbearing potential must agree to utilize highly effective contraception methods from screening throughout the duration of study treatment and for 12 weeks following the last dose of study drug
  • Age ≥ 18 years
  • Life expectancy ≥ 1 year

Exclusion Criteria:

  • A new acquired immunodeficiency syndrome (AIDS)-defining condition diagnosed within the 30 days prior to screening
  • Receiving drug treatment for hepatitis C, or anticipated to receive treatment for hepatitis C
  • Subjects experiencing decompensated cirrhosis
  • Females who are breastfeeding
