Rapid Initiation of Antiretroviral Therapy with Coformulated Bictegravir, Emtricitabine, Tenofovir Alafenamide Versus Efavirenz, Lamivudine and Tenofovir Disoproxil Fumarate in HIV-positive Men Who Have Sex with Men in China: Week 48 Results of the Multicenter, Randomized Clinical Trial
Abstract
BACKGROUND
Most international treatment guidelines recommend rapid initiation of antiretroviral therapy (ART) for people newly diagnosed with HIV-1 infection, but experiences with rapid ART initiation remain limited in China. We aimed to evaluate the efficacy and safety of efavirenz (400-mg) plus lamivudine and tenofovir disoproxil fumarate (EFV + 3TC + TDF) versus coformulated bictegravir, emtricitabine, tenofovir alafenamide (BIC/FTC/TAF) in rapid ART initiation among HIV-positive men who have sex with men (MSM).
METHODS
This multicenter, open-label, randomized clinical trial enrolled MSM aged ≥18 years to start ART within 14 days of confirmed HIV diagnosis. The participants were randomly assigned in a 1:1 ratio to receive EFV(400-mg) + 3TC + TDF or BIC/FTC/TAF. The primary end point was viral suppression (<50 copies/ml) at 48 weeks per FDA Snapshot analysis.
RESULTS
Between March 2021 and July 2022, 300 participants were enrolled; 154 were assigned to receive EFV + 3TC + TDF (EFV group) and 146 BIC/FTC/TAF (BIC group). At week 48, 118 (79.2%) and 140 (95.9%) participants in the EFV and BIC group, respectively, were retained in care with viral suppression; and 24 (16.1%) and 1 (0.7%) participant in the EFV and BIC group (p < 0.001), respectively, discontinued treatment due to adverse effects, death, or loss to follow-up. The median increase of CD4 count was 181 and 223 cells/μL (p = 0.020), respectively, for the EFV and BIC group, at week 48. The overall incidence of…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
