Durham, NC, 17 OCTOBER 2025 ViiV Healthcare announced 96-week findings from PASO DOBLE (GeSIDA 11720 study) showing that Dovato (dolutegravir/lamivudine [DTG/3TC]) is as effective as Biktarvy (bictegravir/emtricitabine/tenofovir alafenamide fumarate [BIC/FTC/TAF]) in maintaining virological suppression in adults with HIV-1. Individuals taking Dovato also experienced statistically significant less weight gain and fewer drug-related adverse events over the two-year study period. Results are presented at the European AIDS Clinical Society (EACS) annual congress, held in Paris, France (15-18 October).

PASO DOBLE is the largest head-to-head, phase IV randomized clinical trial investigating the two-drug regimen Dovato compared to the three-drug regimen BIC/FTC/TAF for the treatment of HIV-1 in people who are virologically suppressed and could benefit from treatment optimization. Results at 96 weeks showed patients who switched to Dovato achieved non-inferior efficacy in maintaining viral suppression compared with switching to BIC/FTC/TAF.
