ViiV Healthcare’s PASO DOBLE study found that the 2-drug regimen Dovato (DTG/3TC) is as effective as the 3-drug regimen Biktarvy (BIC/FTC/TAF) in maintaining viral suppression in HIV-positive individuals. The study included 553 participants who switched to either DTG/3TC or BIC/FTC/TAF. After 48 weeks, the proportion of participants with viral load above 50 copies/mL was similar in both groups.
Importantly, DTG/3TC resulted in significantly lower weight gain compared to BIC/FTC/TAF. The average weight increase in the DTG/3TC group was 0.89kg, while the average increase in the BIC/FTC/TAF group was 1.81kg. This difference may be significant for individuals concerned about treatment-related weight gain. The weight gain with DTG/3TC did not differ based on gender or previous regimen, but the risk of gaining more than 5% weight with BIC/FTC/TAF was notably higher when switching from a regimen with abacavir.
These findings highlight the potential benefits of switching to DTG/3TC for virologically suppressed HIV-positive individuals seeking treatment optimization. Dovato’s non-inferior efficacy and lower weight gain profile compared to Biktarvy provide valuable options for improving the quality of life for people living with HIV.
