Participants will switch to E/C/F/TAF FDC tablet for up to 96 weeks in the Randomized Phase, and may continue treatment with E/C/F/TAF in the open-label Extension Phase.
Elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) (150/150/200/10 mg) FDC tablet administered orally once daily
Other Name: Genvoya®
Active Comparator: Stay on Baseline Treatment Regimen (SBR)
Participants will stay on their baseline FTC/tenofovir disoproxil fumarate (TDF)-containing regimen (either E/C/F/TDF, EFV/FTC/TDF, RTV+ATV+FTC/TDF, or COBI+ATV+FTC/TDF) for up to 96 weeks in the Randomized Phase, and may switch to E/C/F/TAF in the open-label Extension Phase.

- Percentage of Participants With HIV-1 RNA < 50 Copies/mL at Week 48 [ Time Frame: Week 48 ]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.
- Percent Change From Baseline in Hip Bone Mineral Density (BMD) at Week 48 [ Time Frame: Baseline; Week 48 ]Hip BMD was assessed by dual energy x-ray absorptiometry (DXA) scan. BMD is calculated as grams per square centimeter (g/cm^2); the mean (SD) percentage change is presented.
- Percent Change From Baseline in Spine BMD at Week 48 [ Time Frame: Baseline; Week 48 ]Spine BMD was assessed by DXA scan. BMD is calculated as g/cm^2; the mean (SD) percentage change is presented.
- Change From Baseline in Serum Creatinine at Week 48 [ Time Frame: Baseline; Week 48 ]
- Change From Baseline in Overall EFV-related Symptom Assessment Score at Week 48 [ Time Frame: Baseline; Week 48 ]
The mean (SD) change of the overall EFV-related symptom assessment score is presented. The overall symptom score (ranging from 0 to 20) is the sum of the individual symptom scores ranging from 0 (no symptoms) to 4 (most severe symptoms) from the 5 EFV-related symptom assessments (dizziness, trouble sleeping, impaired concentration, sleepiness, and abnormal or vivid dream).
EFV-Related Symptom Analysis Set: participants who received EFV/FTC/TDF as prior treatment, received at least 1 dose of study drug, and completed EFV-related symptom assessments at the baseline visit and at least 1 postbaseline visit.
