Brief Summary

The primary objective of this study is to evaluate the efficacy of a fixed dose combination (FDC) containing bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus a FDC containing abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) in HIV-1 infected, antiretroviral treatment naive-adults.

Inclusion Criteria
  • Antiretroviral treatment naive (≤ 10 days of prior therapy with any antiretroviral agent following a diagnosis of HIV-1 infection) except the use for pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP), up to one month prior to screening
  • Plasma HIV-1 ribonucleic acid (RNA) levels ≥ 500 copies per milliliter (mL) at screening

Open-label Phase B/F/TAF to B/F/TAFB/F/TAFAfter Week 144, participants will continue to take their blinded study drug and attend visits every 12 weeks until the End of Blinded Treatment Visit. Following the End of Blinded Treatment Visit, participants will be given the option to receive open-label (OL) B/F/TAF for 96 weeks. After the Week 96 OL Visit, participants in a country where B/F/TAF is not commercially available will be given the option to continue OL B/F/TAF until the product becomes accessible through an access program or until Gilead elects to discontinue the study in that country, whichever occurs first.

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 48 as Defined by the US FDA-Defined Snapshot AlgorithmWeek 48

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.

The percentage of participants achieving HIV-1 RNA \< 50 copies/mL at Week 144 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.

Percentage of Participants Who Achieved HIV-1 RNA < 20 Copies/mL at Week 48 as Defined by the US FDA-Defined Snapshot AlgorithmWeek 48

Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 48 Open-Label as Defined by Missing = Excluded AlgorithmBaseline, open-label Week 48

The percentage of participants with HIV-1 RNA \< 50 copies/mL was analyzed using Missing = Excluded for imputing missing HIV-1 RNA values using the All B/F/TAF Analysis Set. All missing data was excluded in the computation of the percentages (ie, missing data points were excluded from both the numerator and denominator in the computation). The denominator for percentages at a visit was the number of participants in the all B/F/TAF analysis set with non-missing HIV-1 RNA value at that visit.

Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 48 Open-Label as Defined by Missing = Failure AlgorithmBaseline, open-label Week 48

The percentage of participants with HIV-1 RNA \< 50 copies/mL was analyzed using Missing = Failure for imputing missing HIV-1 RNA values using the All B/F/TAF Analysis Set. All missing data was treated as HIV-1 RNA ≥ 50 copies/mL. The denominator for percentages was the number of participants in all B/F/TAF analysis set.

Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 96 Open-Label as Defined by Missing = Excluded AlgorithmBaseline, open-label Week 96

The percentage of participants with HIV-1 RNA \< 50 copies/mL was analyzed using Missing = Excluded for imputing missing HIV-1 RNA values using the All B/F/TAF Analysis Set.
