Summary

The aim of this study is to determine if virologically suppressed Human Immunodeficiency Virus (HIV) Type 1 infected adults on a current antiretroviral regimen (CAR) (including 2 nucleoside reverse transcriptase inhibitors \[NRTIs\] plus a third agent) remain suppressed upon switching to dolutegravir/lamivudine (DTG/3TC) fixed dose combination (FDC). The main objective of the study is to demonstrate the non-inferior antiviral activity of switching to DTG/3TC FDC once daily compared to continuation of CAR over 48 weeks in virologically suppressed adults living with HIV-1. The study will also evaluate information regarding the safety and health related quality of life. The study will include Screening Phase (up to 28 days), a Randomization Phase (up to Week 52) and a Continuation Phase (post Week 52). The Continuation Phase is not applicable for participants in Sweden and Denmark. Approximately 490 participants will be randomized in 1:1 ratio to receive DTG/3TC FDC once daily for up to 52 weeks or continue their CAR for 52 weeks. Participants in the DTG/3TC FDC arm who successfully complete up to 52 weeks of treatment will have the opportunity to continue receiving DTG/3TC FDC once daily in Continuation Phase.
