Randomized Controlled Trial Multicenter Study
Darunavir/cobicistat/emtricitabine/tenofovir alafenamide in treatment-naïve patients with HIV-1: subgroup analyses of the phase 3 AMBER study.
Background: The once-daily, single-tablet regimen darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg is approved for the treatment of HIV-1 infection. The 48-week efficacy and safety of D/C/F/TAF versus darunavir/cobicistat + emtricitabine/tenofovir disoproxil fumarate (control) in treatment-naïve adults were demonstrated in the phase 3 AMBER study. Objective: To describe AMBER outcomes across patient subgroups based on demographic and clinical characteristics at baseline. ⋯ Adverse event rates were similar in both arms, although numerically higher among patients >50 years and women, relative to their comparator groups, regardless of treatment arm (notably, sample sizes were small for patients >50 years and women). Improvements in eGFRcystC and stable bone mineral density were observed with D/C/F/TAF overall, and results were generally consistent across subgroups. Conclusions: For treatment-naïve patients in AMBER, initiating therapy with the D/C/F/TAF single-tablet regimen was an effective and well-tolerated option, regardless of demographic or clinical characteristics.
