- ≥18 years of age
- Naïve to ARV therapies (defined as ≤ 10 days of prior therapy with any antiretroviral therapy following an HIV diagnosis). Previous use of PrEP or PEP is allowed if there is documented HIV seronegativity between the last prophylactic dose and the date of HIV diagnosis.
- HIV RNA at screening visit \> or = 1,000 copies/mL. A previous result performed on the last 30 days can be used.
- CD4 at screening \< or = 200 cells/mL A previous result performed on the last 30 days can be used.
- Subjects can comply with protocol requirements.
- Subject agrees not to take any medication during the study, including over-the-counter medicines or herbal preparations, without the approval of the trial physician.
- Subject's general medical condition, in the investigator's opinion, does not interfere with assessments and completion of the study.

- Any contraception method must be used consistently, in accordance with the approved product label. All subjects participating in the study should be counselled on safer sexual practices including the use of effective barrier methods and the choice of effective contraceptive method should be documented in the eCRF.
Exclusion
- Women who are pregnant or breastfeeding, or women who plan to become pregnant in the next year.
- Subjects testing positive for Hepatitis B surface antigen (+HBsAg) at screening, or anticipated need for Hepatitis C virus (HCV) therapy with drugs with potential drug-drug interaction during the study.

Subjects with other suspected or confirmed active opportunistic infections and subjects with cryptococcal disease after the initial period can be included if she/he can follow the protocol and if her/his participation could benefit the subject. A clear documentation of these aspects must to be done in the clinical chart of the participant.
- Subjects who in the investigator's judgment, pose a significant suicidality risk.
- History or presence of allergy to the study drugs or their components or drugs of their class
- Treatment with any of the following agents within 28 days of screening: radiation therapy; cytotoxic chemotherapeutic agents; any immunomodulators that alter immune responses; or treatment with an HIV-1 immunotherapeutic vaccine within 90 days of screening; or 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 investigational product.
- Any previous evidence of resistance to dolutegravir (defined as the presence of G118R, Q148 H/K/R or R263K), to lamivudine (presence of the mutation M184V) or resistance to tenofovir (mutation K65R or more than 3 TAMs) with a Sanger sequence method or using next-generation sequencing (NGS) at a frequency \>15%. If the subject does not have a previous resistance test, samples will be taken at the screening visit and the subject can be randomized and start the study. while awaiting the results (see section 4.8).
- Any verified Grade 4 abnormality.
- Alanine aminotransferase (ALT) ≥ 5 times the upper limit of normal (ULN), or ALT ≥ 3xULN and bilirubin ≥ 1.5xULN (with \>35% direct bilirubin).
