Efficacy and safety were evaluated as virological failure (VF=2 consecutive HIV-RNA> 50 copies/mL or a single HIV-RNA> 400 copies/mL) and treatment failure (TF=VF or discontinuation for any reason) until data freezing (August 2022).Results: Of the 1040 PLWH included, 67.8% switched from elvitegravir/cobicistat/FTAF. VF occurred in 4.2% (n=44), with incidence rate of 1.63 per 1000 person-months of follow-up (PMFU) and probability at 24– 30 months of 3.8%– 4.0%, respectively. Out of the 44 VF, in 75% virological re-suppression was achieved while maintaining BFTAF. Discontinuation occurred in 15% after a median time of 13.5 months of follow-up, with an incidence rate of 5.67 per 1000 PMFU, and a probability at 24– 30 months of 11.9%– 15.3%, respectively. Main discontinuation reasons were simplification (51.3%) and toxicity (21.8%, involving CNS in half of cases). TF occurred in 18.6% with an incidence rate of 7.01 per 1000 PMFU after a median time of 13.6 observation months; probability at 24– 30 months was 14.8%– 18.4%, respectively.Conclusion: BFTAF has proven effective and well tolerated in clinical practice.Plain Language Summary: In Clinical Randomized Trials, BFTAF proved to have a high genetic barrier regimen.In this context of clinical practice:BFTAF proved effective and well toleratedIt showed a low rate of virological failureDiscontinuation was largely influenced by simplification with 2-drug regimens.Keywords: bictegravir, people living with HIV, PLWH, efficacy, safety, clinical practice |
