Background: First-line integrase strand transfer inhibitor-based regimens have become commonly used in clinical practice over the last decade. This study aimed to analyse and compare the efficacy and safety of bictegravir (BIC) and dolutegravir (DTG) when prescribed in association with emtricitabine/tenofovir alafenamide (FTC/TAF) as part of a first-line regimen for the treatment of human immunodeficiency-1 (HIV-1) infection. Methods: Treatment-naïve people living with HIV (PLWHIV) starting a first-line regimen with either BIC/FTC/TAF (BIC group) or FTC/TAF+DTG (DTG group) were analysed. Snapshot analyses were performed after 24 and 48 weeks to evaluate virological efficacy. In addition, differences in the rate of treatment discontinuation (TD) between the two groups were evaluated using the Kaplan-Meier method and the log rank test. Results: Data from 327 PLWHIV were analysed: 140 in the DTG group and 187 in the BIC group. At 48 weeks, 90.0% of individuals in the DTG group and 86.7% of those in the BIC group achieved HIV-RNA <50 copies/mL. In total, 88 and 38 cases of TD were observed in the DTG group and BIC group, respectively. The estimated probability of maintaining the study regimen at week 48 was 59.5% in the DTG group and 84.2% in the BIC group. Analysing changes in immunological parameters after 48 weeks, median improvements of +169 cell/mm3 (P<0.001) and +233 cell/mm3 (P<0.001) were observed in the DTG group and the BIC group, respectively. Conclusions: Both BIC and DTG, in combination with FTC/TAF, show promising efficacy and safety as first-line strategies in clinical practice, with favourable immunological recovery even in the short term.

Abstract

Background: First-line integrase strand transfer inhibitor-based regimens have become commonly used in clinical practice over the last decade. This study aimed to analyse and compare the efficacy and safety of bictegravir (BIC) and dolutegravir (DTG) when prescribed in association with emtricitabine/tenofovir alafenamide (FTC/TAF) as part of a first-line regimen for the treatment of human immunodeficiency-1 (HIV-1) infection. Methods: Treatment-naïve people living with HIV (PLWHIV) starting a first-line regimen with either BIC/FTC/TAF (BIC group) or FTC/TAF+DTG (DTG group) were analysed. Snapshot analyses were performed after 24 and 48 weeks to evaluate virological efficacy. In addition, differences in the rate of treatment discontinuation (TD) between the two groups were evaluated using the Kaplan-Meier method and the log rank test. Results: Data from 327 PLWHIV were analysed: 140 in the DTG group and 187 in the BIC group. At 48 weeks, 90.0% of individuals in the DTG group and 86.7% of those in the BIC group achieved HIV-RNA <50 copies/mL. In total, 88 and 38 cases of TD were observed in the DTG group and BIC group, respectively. The estimated probability of maintaining the study regimen at week 48 was 59.5% in the DTG group and 84.2% in the BIC group. Analysing changes in immunological parameters after 48 weeks, median improvements of +169 cell/mm3 (P<0.001) and +233 cell/mm3 (P<0.001) were observed in the DTG group and the BIC group, respectively. Conclusions: Both BIC and DTG, in combination with FTC/TAF, show promising efficacy and safety as first-line strategies in clinical practice, with favourable immunological recovery even in the short term.
