NCT07618507

Brief Summary

The goal of this study is to understand the profile of individuals who demonstrate transmitted drug resistance to Dolutegravir (DTG) among PLHIV in Brazil in terms of the subtypes of virus and other individual characteristics after 24 weeks of treatment with a regimen of DTG, Tenofovir, and Lamivudine (TL+D). The study also seeks to determine what alterations occur in the 3'-PPT region of the HIV virus in patients with failing the TL+D regimen. The test group will be compared to a control group of individuals randomly selected whose viral control remains below detection limit (50 copies/mL) for 24 weeks after the initiation of treatment. The study uses clinics in cities in each of the five regions of Brazil: South region (Porto Alegre, Viamão), Southeast region (São Paulo, Santos, Guarujá), Northeast region (Salvador), Center West region (Brasília), and the North region (Manaus). Porto Alegre and Viamão are of interest because of the strong presence of subtype C in the South region. Salvador is a focus for subtype F of HIV. Finally, in Santos there is a strong presence of recombinant forms of subtypes F and B. These non-B subtypes are important to the study as they are typical of other medium and low income countries. The plan for the study includes 200 cases who will receive the TL+D medication for 24 weeks (50 in each region) and 400 controls again spread among the regions on a 1 (case): 2(control ratio.
