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 144 weeks.

Open-Label Extension Phase: After the unblinding visit, in countries where E/C/F/TAF FDC was not commercially available, participants (except in UK) were given the option to receive the open-label E/C/F/TAF FDC until it became commercially available, or until Gilead 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 144 weeks.

Open-Label Extension Phase: After the unblinding visit, in countries where E/C/F/TAF FDC was not commercially available, participants (except in UK) were given the option to receive the open-label E/C/F/TAF FDC until it became commercially available, or until Gilead terminated the study in that country.

Statistical Analysis Overview Comparison Group Selection E/C/F/TAF, E/C/F/TDF
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.
Type of Statistical Test Superiority or Other (legacy)
Comments [Not Specified]
Statistical Test of Hypothesis P-Value 0.13
Comments [Not Specified]
Method Cochran-Mantel-Haenszel
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).
Method of Estimation Estimation Parameter Difference in Percentages
Estimated Value 3.1
Confidence Interval (2-Sided) 95.002%
-1.0 to 7.1
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.
