<qa>  What is the name of the two drug regimen of dolutegravir?This study will compare safety, efficacy, and tolerability of a two drug regimen of dolutegravir DTG plus lamivudine 3TC administered once daily with DTG plus two nucleoside reverse transcriptase inhibitors Tenofovir TDFEmtricitabine FTC fixed dose combination FDC administered once daily in human immunodeficiency virus HIV 1 infected adult subjects that have not previously received antiretroviral therapy. The study is designed to demonstrate the non-inferior antiviral activity of DTG plus 3TC regimen to that of DTG plus TDFFTC FDC and will characterise the long term antiviral activity, tolerability and safety of DTG plus 3TC through Week 148. Approximately, 700 subjects will be randomised 1:1 to receive DTG 3TC or DTG TDFFTC FDC. Subjects will be stratified by screening HIV 1 ribonucleotide nucleic acid RNA levels and by screening CD4 cluster of differentiation 4 cell count.
