Abstract
Introduction
We aimed to determine whether doravirine/lamivudine/tenofovir disoproxil fumarate (DOR/3TC/TDF) given 5 or 4 days a week was able to maintain viral suppression in people living with HIV (PLHIV).
Methods
In this observational, retrospective study, we included all PLHIVs who had received intermittent DOR/3TC/TDF between 10/01/2019 and 01/31/2021, in two French hospitals.
Results
Forty-three PLHIVs were included, median (IQR) age: 52 years (48–58), ART duration: 15 years (8–23), duration of virological suppression: 6 years (2–10). Median follow-up was 78 weeks (IQR 62–97). One virological failure (VF) occurred at W38 (HIV-RNA = 61 and 76 copies/mL), in a patient with no viral resistance at baseline or at time of VF, and during the study period five individuals discontinued DOR/3TC/TDF due to adverse events. There were no significant changes during follow-up in the CD4 count, CD4/CD8 ratio, body weight or residual viremia rate.
Conclusion
These findings suggest the potential for intermittent DOR/3TC/TDF to maintain virological control.
