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.

Condition Intervention Phase

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

Primary Outcome Measures:
  • 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.

Secondary Outcome Measures:
  • 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.

  • Plasma HIV-1 RNA levels ≥ 5,000 copies/mL
  • 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)
  • Total bilirubin ≤ 1.5 mg/dL, or normal direct bilirubin

  • 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
  • Positive serum pregnancy test (female of childbearing potential)
  • Implanted defibrillator or pacemaker
  • Current alcohol or substance use judged by the Investigator to potentially interfere with subject study compliance
  • History of malignancy within the past 5 years or ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, noninvasive cutaneous squamous carcinoma
  • Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to baseline
  • Medications contraindicated for use with EVG, COBI, FTC, EFV, or TDF; or subjects with any known allergies to the excipients of Stribild or Atripla tablets
  • Participation in any other clinical trial without prior approval
  • Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for the study or unable to comply with the dosing requirements
