Abstract
Background:
Head-to-head data for bictegravir/emtricitabine/tenofovir alafenamide (BIC/F/TAF; B) and darunavir/cobicistat/emtricitabine/tenofovir alafenamide (DRV/c/F/TAF; D) are lacking in the context of rapid antiretroviral therapy (ART) initiation. This study, BIC-T&T, evaluates the efficacy and tolerability of B vs D in a UK test‐and‐treat setting.
Setting:
BIC-T&T was a randomised, open-label, multi-centre, study in which participants initiated ART within 14 days after confirmed HIV‐1 diagnosis before baseline laboratory.
Methods:
The primary endpoint is the virological response (HIV RNA < 50copies/mL) at week 12 by time-weighted average change in log10 HIV RNA recorded in viral load assays from treatment initiation to week 12, using two-sample Wilcoxon rank-sum test.
Results:
36 participants were randomised: 94% were male, 53% white; mean (SD) age was 35 years (11.8). Baseline mean (±SD) log10 HIV-RNA was 4.79 (± 0.87) log10 copies/mL and CD4 505 (±253) cells/mm3. The mean (±SD) time from confirmed HIV diagnosis to ART initiation was 7.9 (± 3.7) days. The time-weighted mean decrease in log10 HIV RNA from treatment initiation to week 12 was significantly greater in B in comparison to D (3.1 vs. 2.6 log10 copies/mL, p < 0.001). Both regimens demonstrated good tolerability with infrequent laboratory abnormalities and no grade 3 or 4 adverse events.
Conclusion:
In this first head-to-head study in the context of ART initiation, HIV RNA decline from baseline to week 12 was significantly more rapid for BIC/F/TAF compared with DRV/c/F/TAF.
