Description of intervention(s) / exposure
Treatment: Drugs - ABC/DTG/3TC
Treatment: Drugs - B/F/TAF
Treatment: Drugs - ABC/DTG/3TC Placebo
Treatment: Drugs - B/F/TAF Placebo

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

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

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.

Outcomes

Percentage of Participants With Virologic Failure (HIV-1 RNA = 50 Copies/mL) as Defined by the Modified US FDA-defined Snapshot Algorithm - 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.

Summary
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 HIV-1 infected adults.
