Brief Summary

The primary objective of this study is to evaluate the efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) versus elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) in HIV-1 positive, antiretroviral treatment-naive adults.

Exclusion Criteria
  • A new AIDS-defining condition diagnosed within the 30 days prior to screening
  • Hepatitis B surface antigen (HBsAg) positive
  • Hepatitis C antibody positive
  • Individuals experiencing decompensated cirrhosis
  • Females who are breastfeeding
  • Positive serum pregnancy test
  • Have an implanted defibrillator or pacemaker

  • 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
  • Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the individual unsuitable for the study or unable to comply with dosing requirements
  • Participation in any other clinical trial (including observational trials) without prior approval
  • Receiving ongoing therapy with drugs not to be used with elvitegravir, cobicistat, emtricitabine, tenofovir DF, and TAF or participants with any known allergies to the excipients of E/C/F/TDF or E/C/F/TAF

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Achieving HIV-1 RNA < 50 Copies/mL at Week 48Week 48

The percentage of participants achieving HIV-1 RNA \< 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a patient'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.

Secondary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Urine RBP to Creatinine Ratio at Week 96Baseline; Week 96

Urine RBP is a renal biomarker which is used to detect drug-induced kidney injury.

Percent Change From Baseline in Urine Beta-2-microglobulin to Creatinine Ratio at Week 48Baseline; Week 48

Urine Beta-2-microglobulin is a renal biomarker which is used to detect drug-induced kidney injury.

Percentage of Participants With Treatment-emergent Proteinuria Through Week 48Baseline to Week 48

Grades 1 (mild), 2 (moderate), and 3 (severe) were the highest treatment-emergent postbaseline grades for urine protein using the dipstick method. The worst postbaseline value is presented for each participant.

Percentage of Participants With Treatment-emergent Proteinuria Through Week 96Baseline to Week 96

Grades 1 (mild), 2 (moderate), and 3 (severe) were the highest treatment-emergent postbaseline grades for urine protein using the dipstick method. The worst postbaseline value is presented for each participant.

Percent Change From Baseline in Urine Retinol Binding Protein (RBP) to Creatinine Ratio at Week 48Baseline; Week 48

Urine RBP is a renal biomarker which is used to detect drug-induced kidney injury.
