Eligibility
Key inclusion criteria
- Must be an HIV 1 infected adult >=18 years of age (or older, if required by local
regulations) at the time of signing the informed consent

- An eligible female participant should not be pregnant (as confirmed by a negative
serum human chorionic gonadotrophin (hCG) test at Screening and negative urine test at
Baseline), not lactating, and at least one of the following conditions applies

- Non reproductive premenopausal women are those that have undergone documented
tubal ligation or documented hysteroscopic tubal occlusion procedure with follow
up confirmation of bilateral tubal occlusion or documented bilateral oophorectomy
or hysterectomy

Participants negative for HBV core antibody (anti HBs) but positive for anti HBc (negative
HBsAg status) and positive for HBV deoxyribose nucleic acid (DNA) will be excluded;
however, participants positive for anti HBc (negative HBsAg status) and positive for anti
HBs (past and/or current evidence) are immune to HBV and will not be excluded

- Anticipated need for any hepatitis C virus (HCV) therapy during the first 48 weeks of
the study and for HCV therapy based on interferon or any drugs that have a potential

investigator and the Study Medical Monitor for inclusion of the participant

- Participants who in the Investigator's judgment, poses a significant suicidality risk.
Recent history of suicidal behaviour and/or suicidal ideation may be considered as
evidence of serious suicide risk

- Treatment with an HIV 1 immunotherapeutic vaccine within 90 days of Screening

- Treatment with any of the following agents within 28 days of Screening:

- Radiation therapy,

- Cytotoxic chemotherapeutic agents,

- Any systemic immune suppressant

- Treatment with any agent, except recognised ART as allowed above, with documented
activity against HIV 1 in vitro within 28 days of first dose of study treatment

- Exposure to an experimental drug or experimental vaccine within either 28 days, 5 half
lives of the test agent, or twice the duration of the biological effect of the test
agent, whichever is longer, prior to the first dose of study treatment

- Participants enrolled in France: the participant has participated in any study using
an investigational drug during the previous 60 days or 5 half lives, or twice the
duration of the biological effect of the experimental drug or vaccine, whichever is
longer, prior to screening for the study or the participant will participate
simultaneously in another clinical study

- Any evidence of pre existing viral resistance based on the presence of any major
resistance associated mutation in the Screening result or, if known, in any historical
resistance test result

- Any verified Grade 4 laboratory abnormality. A single repeat test is allowed during
the Screening period to verify a result

- Any acute laboratory abnormality at Screening, which, in the opinion of the
Investigator, would preclude the participants participation in the study of an
investigational compound

- Alanine aminotransferase (ALT) >=5 times the upper limit of normal (ULN) or ALT
>=3xULN and bilirubin >=1.5xULN (with >35% direct bilirubin)

- Creatinine clearance of <50 mL/min per 1.73 m^2 via the chronic kidney disease
epidemiology collaboration (CKD EPI) method

Summary
Brief summary
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 disoproxil fumarate
[TDF]/emtricitabine [FTC] fixed dose combination [FDC]) administered once daily in human
immunodeficiency virus (HIV) 1 infected adult participants that have not previously received
antiretroviral therapy. The study is designed to demonstrate the non inferior antiviral
activity of DTG + 3TC regimen to that of DTG + TDF/FTC FDC and will characterise the long
term antiviral activity, tolerability and safety of DTG plus 3TC through Week 148.
Approximately, 700 participants will be randomised 1:1 to receive DTG + 3TC or DTG + TDF/FTC
FDC. Participants will be stratified by screening HIV 1 ribonucleotide nucleic acid (RNA)
levels and by screening CD4+ (cluster of differentiation 4) cell count.
