Eligibility Criteria
Inclusion
- 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
- Non reproductive premenopausal women are those with 12 months of spontaneous amenorrhea and \>=45 years of age
- Women with reproductive potential agree to follow one of the protocol-defined methods for avoiding pregnancy
- Should have screening plasma HIV 1 RNA levels of 1000 c/mL to \<=100,000 c/mL. If an independent review of accumulated data from other clinical trials investigating the DTG plus 3TC dual regimen is supportive of the DTG plus 3TC treatment regimen, enrolment will be opened to participants with Screening plasma HIV 1 RNA of 1000 c/mL to \<=500,000 c/mL
- Participants should be antiretroviral naïve (defined as \<=10 days of prior therapy with any antiretroviral agent following a diagnosis of HIV 1 infection). Participants who received HIV post exposure prophylaxis (PEP) or pre exposure prophylaxis (PrEP) in the past are allowed as long as the last PEP/PrEP dose was \>1 year from HIV diagnosis or there is documented HIV seronegativity between the last prophylactic dose and the date of HIV diagnosis
- Participant or the participants legal representative capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and the protocol
- Participants enrolled in France: a participant will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category
- Exclusion Criteria
- Women who are breastfeeding or plan to become pregnant or breastfeed during the study
- Any evidence of an active centers for disease control and prevention (CDC) Stage 3 disease (CDC, 2014), except cutaneous Kaposi's sarcoma not requiring systemic therapy and historical or current CD4 cell counts less than 200 cells/mm\^3
- Participants with severe hepatic impairment (Class C) as determined by Child Pugh classification
- Unstable liver disease (as defined by the presence of ascites, encephalopathy, coagulopathy, hypoalbuminaemia, oesophageal or gastric varices, or persistent jaundice), cirrhosis, known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones
- Evidence of hepatitis B virus (HBV) infection or HBV surface antibody (anti-HBs or HBsAb) based on:
- Participants positive for HBV surface antigen (HBsAg) at screening will be excluded 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 B 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 for adverse drug:drug interactions with study treatment throughout the entire study period
- Untreated syphilis infection positive RPR at Screening without clear documentation of treatment. Participants who are at least 14 days post completed treatment are eligible
- History or presence of allergy or intolerance to the study drugs or their components or drugs of their class
- Ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non invasive cutaneous squamous cell carcinoma, or cervical, anal or penile intraepithelial neoplasia; other localised malignancies require agreement between the 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
