Genders Eligible for Study
Description
Inclusion Criteria:
- Subject has voluntarily signed and dated an informed consent form, approved by an Institutional Review Board (IRB) / Independent Ethics Committee (IEC), after the nature of the study has been explained and the subject has had the opportunity to ask questions.
- Documented HIV-1 infection defined as a positive rapid test or ELISA plus a plasma HIV-1 RNA (>1,000 copies/mL) or a positive western blot. A previous result performed on the last 30 days can be used.
- ≥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.
A female may be eligible to enter and participate in the study if she is not pregnant (as confirmed by serum pregnancy test negative at screening, and a urine negative test at baseline), not lactating and at least one of the following condition applies:
- Women with non-reproductive potential, defined as pre-menospausal females with documented tubal ligation or hysterectomy, or bilateral oophorectomy; or as post-menospausal women defined as 12 months of spontaneous amenorrhea, and ≥45 years of age in women without hormonal replacement therapy.
- Women with reproductive potential and agrees to follow one of the contraceptive options listed in the Appendix 3 from at least 15 days prior to the first dose of medication and until at least 30 days after the last dose of study medication and completion of the follow-up visit.
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 Criteria:

A clear documentation of these aspects must to be done in the clinical chart of the participant.

- 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, the investigator can take the samples and randomize the subject while awaiting the results (see section 4.8 for follow up).
- 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)
