1.Primary Outcome
Title Percentage of Participants With HIV-1 RNA ≥ 50 Copies/mL at Week 48 as Defined by the US FDA-Defined Snapshot Algorithm
Hide Description The percentage of participants with 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.

Hide Statistical Analysis 1
Statistical Analysis Overview Comparison Group Selection B/F/TAF, DTG + F/TAF
Comments The null hypothesis was that the B/F/TAF group is at least 4% higher than the DTG + F/TAF group with respect to the percentage of participants with HIV-1 RNA ≥ 50 copies/mL as determined by the US FDA-defined snapshot algorithm at Week 48; the alternative hypothesis was that the B/F/TAF group is less than 4% higher than the DTG + F/TAF group with respect to the percentage of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48.
Type of Statistical Test Non-Inferiority
Comments A sample size of 260 participants per treatment group would provide at least 90% power to detect a non-inferiority margin of 4% in difference in percentage of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48 between the two treatment groups. This was based on the assumptions that both treatment groups have 2% of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48 (based on Gilead Genvoya and Stribild studies) and that the significance level of the test is at a one-sided 0.025 level.
Method of Estimation Estimation Parameter Difference in Percentages
Estimated Value -0.7
Confidence Interval (2-Sided) 95.001%
-2.8 to 1.0
Estimation Comments The differences in percentages of participants between treatment groups and their 95.001% confidence intervals (CI) were calculated based on an unconditional exact method using 2 inverted 1-sided tests.
