Abstract

Objective: Real-world data on bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) fixed-dose combination from resource-constrained settings like Latin America are limited.

Methods: We conducted an observational retrospective cohort study of treatment-naive (TN, n=315) and treatment-experienced (TE, n= 2356) people living with HIV prescribed BIC/FTC/TAF in Argentina from 10/2019 to 12/2021, with 24 and 48-week follow-up data analyzed for virological suppression, persistence, safety, and metabolic parameters. Patient-reported outcomes were assessed via across-sectional online survey.

Results: Baseline characteristics: median age 45 years, 72.2% male, 99.6% Hispanic/Latino ethnicity. Treatment per sistence at 48 weeks was 99.3% (TN) and 99.5% (TE). Virological suppression rates (<200/<50 copies/mL) at 24 weeks were 97.4/88% (TN) and 99/97% (TE). At 48 weeks were 100/92% (TN) and 99/97% (TE). In the TE group, triglycerides decreased with no other lipid changes. In TN, mild total/LDL/HDL cholesterol increases occurred. eGFR mildly decreased in both groups. The online survey (n=536) showed 91.5% reported no medication concerns. Median quality of life scores were 90 (TN) and 88 (TE). Most reported no self-care, activity, mobility, pain/discomfort, or anxiety/depression issues.

Conclusions: BIC/FTC/TAF demonstrated high persistence, safety, virological efficacy, and favorable metabolic profile over 48 weeks. The cross-sectional survey indicated high treatment satisfaction and good quality of life in this cohort from Argentina.
