Primary	Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 48 as Defined by the 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.	Week 48
Secondary	Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 96 as Defined by the US FDA-Defined Snapshot Algorithm	The percentage of participants achieving HIV-1 RNA < 50 copies/mL at Week 96 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.	Week 96
Secondary	Percentage of Participants Who Achieved HIV-1 RNA < 50 Copies/mL at Week 144 as Defined by the US FDA-Defined Snapshot Algorithm	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.

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 nonmissing HIV-1 RNA value at that visit.	Baseline, open-label Week 48
