DTG/3TC versus BIC/TAF/FTC as first-line HIV treatment for people new to antiretrovirals
Official title: Safety, Tolerability and Effectiveness of DOlutegravir/Lamivudine Compared With Bictegravir/Tenofovir Alafenamide/Emtricitabine in People Living With HIV Without Antiretroviral Experience (TEOTL)
Run by Instituto Mexicano del Seguro Social · NCT07031063 · Data updated 2026-11-12
This trial will test whether DTG/3TC gives similar viral control but less weight gain and metabolic side effects than BIC/TAF/FTC in adults newly starting HIV treatment.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with newly diagnosed HIV who are antiretroviral-naive, have HIV-1 RNA between 500 and 500,000 copies/mL, no prior PrEP/PEP, eGFR ≥30 mL/min/1.73 m2, and are treated at the IMSS Infectious Diseases Hospital La Raza who consent to participate.
✕Probably not a fit
People with metabolic syndrome, uncontrolled diabetes, hepatitis B or C coinfection, known resistance mutations to regimen components, contraindications to INSTIs, or who take interacting medications are excluded and likely would not benefit from participation.

What this trial studies
This is an open-label, randomized Phase 4 comparison of two first-line antiretroviral regimens (DTG/3TC versus BIC/TAF/FTC) in treatment-naive adults with HIV seen at the Infectious Diseases Hospital, Centro Médico Nacional La Raza. Eligible participants will have baseline clinical assessment, labs (including viral load, CD4, glucose, lipids, liver and kidney tests) and body composition measured by segmental bioimpedance, then be randomized via a digital system to one of the two arms. The study will monitor viral suppression, safety, tolerability, weight and other metabolic outcomes over the planned enrollment/follow-up period. Data will be collected during routine clinic visits and analyzed for differences in effectiveness and metabolic adverse effects between the regimens.
Why it matters
Potential benefit: If successful, the results could identify a first-line option that controls HIV while causing less weight gain and reduced long-term metabolic risk.
How similar studies have gone: Large trials have shown both DTG/3TC and BIC/TAF/FTC provide strong viral suppression, but direct head-to-head data on comparative weight gain and metabolic effects are limited, so this comparison addresses a partly novel question.
