Double-Blind Phase: Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) (150/150/200/10 mg) fixed-dose combination (FDC) tablet plus elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) placebo tablet administered orally once daily for at least 144 weeks.

Open-Label Extension Phase: After study unblinding, participants who completed 144 weeks of the study were given the option to receive open-label E/C/F/TAF (150/150/200/10 mg) FDC tablet until commercially available, or until Gilead Sciences terminated the study in that country.

Double-Blind Phase: E/C/F/TDF (150/150/200/300 mg) FDC tablet plus E/C/F/TAF placebo tablet administered orally once daily for at least 144 weeks.

Open-Label Extension Phase: After study unblinding, participants who completed 144 weeks of the study were given the option to receive open-label E/C/F/TAF (150/150/200/10 mg) FDC tablet until commercially available, or until Gilead Sciences terminated the study in that country.

Title Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48
Hide Description The percentage of participants achieving HIV-1 RNA < 50 copies/mL at Week 48 was analyzed using the snapshot algorithm, which defines a patient'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.

Statistical Analysis Overview Comparison Group Selection E/C/F/TAF, E/C/F/TDF
Comments [Not Specified]
Type of Statistical Test Non-Inferiority or Equivalence
Comments Null hypothesis: the E/C/F/TAF group was ≥ 12% worse than the E/C/F/TDF group with respect to the percentage of participants achieving HIV-1 RNA < 50 copies/mL at Week 48; alternative hypothesis: the E/C/F/TAF group was < 12% worse than the E/C/F/TDF group.
Statistical Test of Hypothesis P-Value 0.78
Comments P-value was from the Cochran-Mantel-Haenszel (CMH) test stratified by baseline HIV-1 RNA (≤ 100,000 or > 100,000 copies/mL) and region (US vs ex-US).

-3.0 to 4.0
Estimation Comments The difference in percentages and its 95.002% confidence interval (CI) were calculated based on the Mantel-Haenszel (MH) proportions adjusted by baseline HIV-1 RNA and region stratum.
