Abstract

The primary objective of this study was to assess the effect of a standard high-fat meal on the single-dose (60 mg) pharmacokinetics (PK) of edoxaban in healthy Japanese and Caucasian male volunteers matched by body mass index. This was an open-label, randomized, 2-period crossover study. All 32 enrolled volunteers completed the study per protocol. Both serial blood and urine samples were collected, and edoxaban concentrations were analyzed by a validated liquid chromatography/tandem mass spectrometry method. Activated partial thromboplastin and prothrombin times were obtained as measures of pharmacodynamic effect. The point estimates of the geometric mean ratios (fed/fasted) for AUC(0-t), AUC(0-∞), and C(max) demonstrated modest increases ranging from 6% to 22% across PK parameters for both race cohorts. The disposition was similar in both Japanese and Caucasian matched volunteers with slightly higher AUC values (ranging from 7%-9%) in Caucasians. There were no serious adverse events during the study. All drug-related adverse events were mild and self-limited, and none were bleeding related. Both Japanese and Caucasian volunteers demonstrated a modest but clinically insignificant food effect. It was concluded that edoxaban can be administered without regard to food.
