Brief Summary
The primary objective of this study is to 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 Human Immunodeficiency Virus- 1 (HIV-1) infected adults.

Eligibility Criteria
Key Inclusion Criteria:
* Estimated glomerular filtration rate ≥ 50 mL/min (≥ 0.83 mL/sec).
* Currently receiving an antiretroviral regimen of DTG + ABC/3TC, or ABC/DTG/3TC FDC for ≥ 3 months prior to the screening visit.
* HIV ribonucleic acid (RNA) \< 50 copies/mL at the screening visit.
* Currently on a stable regimen for ≥ 3 months preceding the screening visit with documented plasma HIV-1 RNA \< 50 copies/mL for ≥ 3 months preceding the screening visit (or undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL).

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 Outcomes
Outcome Description
The percentage of participants achieving HIV-1 RNA ≥ 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a participant'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.
Outcome Measure
Percentage of Participants With Virologic Failure (HIV-1 RNA ≥ 50 Copies/mL) as Defined by the Modified US FDA-defined Snapshot Algorithm
Outcome Time Frame
