Study Overview
Brief Summary
The purpose of this study is to demonstrate non-inferiority in efficacy of a darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) fixed dose combination (FDC) tablet versus Darunavir/Cobicistat (DRV/COBI) FDC coadministered with Emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) FDC in human immunodeficiency virus-1 (HIV-1) infected, antiretroviral (ARV) treatment naive adult participants.
Detailed Description
This is a Phase 3, multicenter (when more than one hospital or medical school team work on a medical research study), randomized (study drug assigned by chance), double-blind (a medical research study in which neither the researchers nor the participant know what treatment the participant is receiving), active-controlled (study in which the experimental treatment or procedure is compared to a standard [control] treatment or procedure) study. The study consists of 5 periods: a Screening period, Double-blind treatment period, Single-arm treatment period, Extension period and a Follow-up period. Participants will receive either darunavir (DRV)/ cobicistat (COBI)/emtricitabine (FTC) /tenofovir alafenamide (TAF) fixed dose combination (D/C/F/TAF FDC) or DRV/COBI FDC along with FTC/TDF FDC. Primarily percentage of participants with human immunodeficiency virus (HIV) -1 Ribonucleic acid (RNA) less than (<) 50 copies per milliliter (copies/ml) defined by snapshot analysis will be evaluated. Participants' safety will be monitored throughout the study.

Outcomes
Primary Outcomes
Percentage of Participants With Human Immunodeficiency Virus (HIV)-1 Ribonucleic Acid (RNA) Less Than (<) 50 Copies Per Milliliter (Copies Per mL) (Virologic Response) at Week 48 Defined by Food and Drug Administration (FDA) Snapshot Approach
Time Frame: At Week 48
Percentage of participants with a HIV-1 RNA \< 50 copies per mL were assessed using FDA snapshot approach 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. The snapshot approach classified participants into 3 outcome categories: 1) virologic success (HIV RNA \< 20/50/200 copies per mL at Week 48), 2) virologic failure (HIV RNA greater than or equal to \[\>=\] 20/50/200 copies per mL at Week 48), 3) no viral load data in the Week 48 visit window (discontinued due to adverse event/death/other reason). The missing HIV-1 RNA is considered as non-response.
