  Purpose

This study is to evaluate the efficacy darunavir/cobicistat/emtricitabine/GS-7340 (D/C/F/TAF) single-tablet regimen (STR) versus darunavir (DRV)+cobicistat (COBI)+emtricitabine(FTC)/tenofuvir disoproxil fumarate (TDF) in HIV-1 infected, antiretroviral treatment-naive adults as determined by the achievement of HIV-1 RNA < 50 copies/mL at Week 24.

  • Normal thyroid-stimulating hormone (TSH)
  • Females of childbearing potential must have a negative serum pregnancy test
  • Females of childbearing potential must agree to utilize highly effective contraception methods from screening throughout the duration of study treatment and for 30 days following the last dose of study drugs
  • Female subjects who are postmenopausal must have documentation of cessation of menses for ≥ 12 months and hormonal failure
  • Female subjects who have stopped menstruating for ≥ 12 months but do not have documentation of ovarian hormonal failure must have a serum follicle stimulating hormone (FSH) level test

  • Hepatitis B surface Antigen positive
  • Hepatitis C Antibody positive
  • Proven acute hepatitis in the 30 days prior to study entry
  • Have a history or experiencing decompensated cirrhosis
  • Current alcohol or substance use that potentially interferes with study compliance
  • Any other clinical condition or prior therapy that would make the subject unsuitable for the study or unable to comply with the dosing requirements
