Rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide as first-line therapy in HIV infection. A prospective study

Abstract

Introduction: Rapid initiation of ART after HIV diagnosis is recommended for individual and public health benefits. However, certain clinical and ART-related considerations hinder immediate initiation of therapy.

Methods: An open-label, single-arm, single-centre 48-week prospective clinical trial involving ART-naïve HIV-diagnosed adults who started bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) within a week from the first hospital visit, before the availability of baseline laboratory and genotype results. The primary aim was to determine the proportion of people with at least one condition that would hinder immediate initiation of any recommended ART regimen other than BIC/FTC/TAF. Clinicaltrials.gov: NCT04416906.

Results: We included 100 participants: 79% men, 64% from Latin America, median age 32 years. According to European AIDS Clinical Society (EACS) and US Department of Health and Human Services 2023 guidelines, 11% (95%CI 6; 19) of participants had at least one condition that made any ART different from BIC/FTC/TAF less appropriate for a rapid ART strategy. Seventy-nine percent of the people started BIC/FTC/TAF within the first 48 hours of their first hospital visit. There were 16 early discontinuations (11 lost to follow-up). By week 48, 92% (95%CI 86; 98) of the participants of the ITT population with observed data achieved viral suppression. Eight grade 3-4 adverse events (AEs), five serious AEs and six ART-related AEs were identified. Adherence remained high.

Conclusions: BIC/FTC/TAF is an optimal treatment for rapid initiation of ART. However, additional strategies to improve retention in care must be implemented.
