- BACKGROUND: In the ARISTOTLE (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation) trial, patients with atrial fibrillation and >= 2 dose-adjustment criteria (age >= 80 years, weight <= 60 kg, or creatinine >= 1.5 mg/dl [133 mu mol/l]) were randomized to receive apixaban 2.5 mg twice daily or warfarin.OBJECTIVES: The purpose of this study was to describe the effects of apixaban dose adjustment on clinical and pharmacological outcomes.METHODS: Patients receiving the correct dose of study drug were included (n = 18,073). The effect of apixaban 2.5 mg twice daily versus warfarin on population pharmacokinetics, D-dimer, prothrombin fragment 1 + 2 (PF1+2), and clinical outcomes was compared with the standard dose (5 mg twice daily).RESULTS: Patients receiving apixaban 2.5 mg twice daily exhibited lower apixaban exposure (median area under the concentration time curve at a steady state 2,720 ng/ml vs. 3,599 ng/ml; p < 0.0001) than those receiving the standard dose. In patients with >= 2 dose-adjustment criteria, reductions in D-dimers (p interaction = 0.20) and PF1+2 (p interaction = 0.55) were consistent with those observed in the standard-dose population. Patients with >= 2 dose-adjustment criteria (n = 751) were at higher risk for stroke/systemic embolism, major bleeding, and all-cause death than the standard-dose population (0 or 1 dose-adjustment criterion, n = 17,322). The effect of apixaban 2.5 mg twice daily versus warfarin in the >= 2 dose-adjustment criteria population was consistent with the standard dose in the reductions in stroke or systemic embolism (p interaction = 0.26), major bleeding (p interaction = 0.25), and death (p interaction = 0.72).CONCLUSIONS: Apixaban drug concentrations were lower in patients receiving 2.5 mg twice daily compared with 5 mg twice daily. However, the effects of apixaban dose adjustment to 2.5 mg versus warfarin were consistent for coagulation biomarkers and clinical outcomes, providing reassuring data on efficacy and safety.
