Switching to a rilpivirine/emtricitabine/tenofovir single-tablet regimen in RNA-suppressed patients infected with human immunodeficiency virus 1: Effectiveness, safety and costs at 96 weeks.

Abstract：

OBJECTIVES:This study evaluates the effectiveness, safety and costs of switching to a rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) regimen in treatment-experienced HIV-1-infected patients with sustained virological suppression. METHODS:Observational, prospective study. Study population included all treatment-experienced patients with sustained virological suppression who switched to RPV/FTC/TDF during 2013 in a tertiary hospital. Patients were followed until they completed 96 weeks of treatment. The effectiveness end-point was defined as the proportion of patients who maintained virological suppression at week 96 by intention-to-treat analysis (discontinuation=failure). The safety of RPV/FTC/TDF (incidence of adverse events leading to discontinuation and laboratory abnormalities) and adherence to this regimen were evaluated, and the cost of switching was analysed. RESULTS:One-hundred forty-six patients were included. At week 96, 71.9% of patients remained virologically suppressed; 6.8% experienced virological failure. During follow-up, 25.3% of patients discontinued RPV/FTC/TDF (14.4% because of adverse events, mainly renal impairment). Throughout the 96 weeks, there were significant decreases in total cholesterol (TC) (14.0 mg/dL, P<.001), TC/HDL cholesterol ratio (0.4 mg/dL, P=.019) and triglycerides (42.0 mg/dL, P<.001). A slight decrease in glomerular filtration rate was observed (4.3 mL/min/1.73 m2 , P<.001). Switching to RPV/FTC/TDF improved adherence in the subgroup of patients whose previous treatment was based on a twice-daily schedule, although differences did not reach statistical significance. Switching to RPV/FTC/TDF reduced the annual per-patient antiretroviral cost by €1744 (P<.001). CONCLUSIONS:In virologically suppressed patients, the switch to a RPV/FTC/TDF regimen was associated with a mild but maintained improvement in lipid parameters and a significant reduction in costs. However, the relatively high rates of virological failure and treatment discontinuation because of adverse events make this combination a less favourable choice over other regimens currently available.
