简要总结
The primary objective of this study is to evaluate whether ASA and darexaban which have different effects on blood coagulation influence each other in their effects. Also it will be investigated whether the blood levels of either drug are influenced by the presence of the other drug. In addition, the safety and tolerability of each drug and the combination of the drugs will be investigated.

结局指标
主要结局
Composite assessment of pharmacodynamics of darexaban and darexaban glucuronide
时间窗: Baseline and after six days of dosing of darexaban, ASA, or a combination of the two
Assessment includes skin bleeding time, factor Xa, platelet aggregation, thromboxane B2 synthesis, PT \& aPTT
次要结局
- Monitoring of safety and tolerability through assessment of vital signs, Electrocardiogram (ECG), clinical safety laboratory and adverse events(6 days for each of the 3 treatment periods)
- Pharmacokinetics of ASA assessed by plasma concentration(Plasma samples are taken until 2 hours after six days of dosing of ASA, or the combination with darexaban)
- Pharmacokinetics of darexaban and darexaban glucuronide assessed by plasma concentration(Plasma samples are taken until 24 hours after six days of dosing of darexaban, or the combination with ASA)
