The novel antiretroviral combination regimen bictegravir-lenacapavir (BIC/LEN; Bixlenvo, Gilead Sciences) maintains high viral suppression rates, even in the presence of preexisting resistance-associated mutations, according to the findings of the phase 3 ARTISTRY-2 trial, which were presented during the HIV Glasgow 2026 (abstract 048).

The trial, which was designed to evaluate the efficacy and safety of switching to the BIC/LEN single-tablet regimen compared with continuing bictegravir, emtricitabine, and tenofovir alafenamide (BIC/FTC/TAF; Biktarvy, Gilead) in 574 participants with HIV, found that the presence of baseline resistance-associated mutations did not affect the efficacy of either regimen during 48 weeks of treatment (P>0.05). Treatment-emergent resistance-associated mutations were rare, occurring in one of the 383 participants who received BIC/LEN; phenotypic susceptibility to the study drugs was maintained.
