Abstract:
Purpose: Our aim was to investigate the durability of
bictegravir/emtricitabine/tenofovir alafenamide (B/F/
TAF) regimen and its safety in a real-life setting. Method: Consecutive people with HIV (PWH) enrolled
in SCOLTA project switching to or initiating their first
antiretroviral treatment (ART) with B/F/TAF were
included. PWH were followed up until treatment discontinuation
and grade 3-4 adverse events (AE) were
recorded. Hazard ratio (HR and 95% confidence interval,
CI) for discontinuation were calculated using the Cox
proportional hazard model.
Results: Of 1164 enrolled PWH, 961 had at least one
follow-up visit and entered the analysis (See Table 1).
Mean age was 48.2 y (±12.6), 75.4% were male, mean
BMI was 25.3 Kg/m2 (±4.5), 27.0% were naïve (N) to antiretrovirals
at T0. The median CD4+ count was 532 cells/
mm3 (interquartile range (IQR) 320-785).
After a median of 24 months of observation (IQR 13-36),
179 (18.6%) discontinued the treatment. The main reason
was the switch to a new treatment reported in 67 PWH
(25 to long-acting ART, 13 to dual treatment, 29 unspecified).
Thirty-five people interrupted due to AE (12 neuropsychiatric),
6 died (4 cancers, 1 sepsis and 1 unknown),
and five had a treatment failure (3 ART-naïve, 2 ARTexperienced).
The median time at discontinuation was
17 months (IQR 8-27). In a multivariate model, older age
was protective (aHR 0.98, 95% CI 0.97-0.99 by 1 year) and
being naïve represented a risk factor for discontinuation
(aHR 1.54, 95% CI 1.08-2.19). CD4+ level >350 cells/
mm3 decreased the likelihood of interruption (aHR 0.73,
95% CI 0.52-1.02, p=0.06). People starting the regimen in
2021-2022 were more likely to discontinue than those
who started in 2019-2020 (aHR 1.65 95% CI 1.19- 2.29).
Conclusions: B/F/TAF shows durability and tolerability
in real-life use. The main reason for discontinuation is
switching to a different regimen for reasons other than
treatment failure or AE occurrence.
