History of Changes


This study will evaluate the efficacy of switching from a regimen of dolutegravir (DTG) and abacavir/lamivudine (ABC/3TC) or a fixed dose combination (FDC) of abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) to a FDC of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus continuing DTG and ABC/3TC as the FDC ABC/DTG/3TC in virologically suppressed HIV-1 infected adults.

Primary Purpose: Treatment
Official Title: A Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of Switching From a Regimen of Dolutegravir and ABC/3TC, or a Fixed Dose Combination (FDC) of ABC/DTG/3TC to a FDC of GS-9883/F/TAF in HIV-1 Infected Subjects Who Are Virologically Suppressed

Primary Outcome Measures

  • Proportion of participants with virologic failure (HIV-1 RNA ≥ 50 copies/mL) as defined by the modified US FDA-defined snapshot algorithm [ Time Frame: Week 48 ]
Secondary Outcome Measures:
  • Proportion of participants with HIV-1 RNA < 50 copies/mL as defined by the US FDA-defined snapshot algorithm [ Time Frame: Week 48 ]
  • Change from baseline in CD4+ cell count at Week 48 [ Time Frame: Baseline and Week 48 ]
  • Percentage change from baseline in hip and spine bone mineral density (BMD) at Week 48 [ Time Frame: Baseline and Week 48 ]

Enrollment: 567
Study Start Date: November 11, 2015
Estimated Study Completion Date: July 2019
Estimated Primary Completion Date: May 9, 2017 (Final data collection date for primary outcome measure)

Arms Assigned Interventions
Experimental: Blinded Phase: B/F/TAF
B/F/TAF + ABC/DTG/3TC placebo for at least 48 weeks
Drug: B/F/TAF

50/200/25 mg FDC tablets administered orally once daily without regard to food

Other Name: GS-9883/F/TAF
Drug: ABC/DTG/3TC Placebo

Tablets administered orally once daily without regard to food

Active Comparator: Blinded Phase: ABC/DTG/3TC
ABC/DTG/3TC + B/F/TAF placebo for at least 48 weeks

600/50/300 mg FDC tablets administered orally once daily without regard to food

Other Name: Triumeq®
Drug: B/F/TAF Placebo

Tablets administered orally once daily without regard to food

Experimental: Open-Label Phase
At the End of Blinded Treatment Visit, if safety and efficacy of B/F/TAF is demonstrated following review of unblinded data, participants in a country where B/F/TAF FDC is not available will be given the option to receive B/F/TAF FDC in an open-label extension phase for up to 96 weeks, or until the product becomes accessible to subjects through an access program, or until Gilead Sciences elects to discontinue the study in that country, whichever occurs first.
Drug: B/F/TAF

50/200/25 mg FDC tablets administered orally once daily without regard to food

Other Name: GS-9883/F/TAF


Ages Eligible for Study: 18 Years and older
