Abstract
Introduction: BIC/FTC/TAF showed efficacy and tolerability in randomized trials as a switch strategy in virologically-suppressed people living with HIV. We evaluated its effectiveness in a real-life setting.
Methods: A retrospective monocentric cohort including 431 virologically-suppressed (HIV-RNA <50 copies/ml) people switching to BIC/FTC/TAF in the period 2018-2022 was evaluated. Probabilities of virological failure (VF, i.e.2 consecutive HIV-RNA ≥50 copies/ml or a single HIV-RNA ≥200 copies/ml) and of treatment discontinuation (TD) were estimated by Kaplan-Meier, and predictors of both outcomes were identified through multivariable Cox regression. Analysis-of-variance for repeated measures was used to examine changes in CD4 count and CD4-to-CD8 ratio.
Results: Overall, 16 VF occurred during 22 months of median follow-up time. Estimated probabilities of VF at 1, 2 and 3 years were 2.0% (95% CI 1.04.2%), 2.9% (95% CI 1.5%-5.6%) and 5.5% (95% CI 3.2%-9.2%), respectively. Caucasian ethnicity and a history of previous VF independently predicted VF. TD occurred in 42 cases, predominantly for simplification. One discontinuation due to VF was reported. No predictors of discontinuation were identified. An increase in CD4-to-CD8 ratio over 3 years was evidenced (p < 0.001). Total cholesterol decreased over 3 years (p < 0.001). Triglycerides did not significantly change (p = 0.465).
Conclusions: BIC/FTC/TAF demonstrated high effectiveness, tolerability and safety.
