Percentage of Participants With Plasma Human Immunodeficiency Virus-1 Ribonucleic Acid (HIV-1 RNA) < 50 Copies/Milliliter at Week 48 in DTG Arm Using the Modified United States (US) Food and Drug Administration (FDA) Snapshot Algorithm
Week 48

Plasma samples were collected for quantitative analysis of HIV-1 RNA. The percentage of participants with plasma HIV-1 RNA \<50 copies/milliliter was assessed at Week 48 using the snapshot algorithm in the DTG arm. Response was assessed using a modified FDA Snapshot algorithm in which participants were not penalized for any single protocol allowed background therapy substitution even if occurs after the first trial visit. In this approach participants with HIV-1 RNA \>=50 copies/milliliter are considered as non-responders. Participants without HIV-1 RNA data at Week 48 (due to missing data or discontinuation of investigational product \[IP\] prior to visit window) are also considered as non-responders, as well as participants with anti-retroviral (ART) substitutions were not permitted. Study drug (i.e. DTG or EFV) was not allowed to be substituted.
