  Purpose

The primary objective of this study is to evaluate whether ASA, the combination of ASA and clopidogrel, 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.

Primary Outcome Measures:
  • Assessment of pharmacodynamics of darexaban [ Time Frame: Baseline and up to 24 hours after six days of dosing of darexaban, ASA, clopidogrel, or a combination ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Assessment of pharmacodynamics of ASA and a combination of ASA and clopidogrel [ Time Frame: Baseline and up to 24 hours after six days of dosing of darexaban, ASA, clopidogrel, or a combination ] [ Designated as safety issue: Yes ]
  • Pharmacokinetics of ASA and the combination of ASA and clopidogrel assessed by plasma concentration [ Time Frame: Plasma samples are taken until 24 hours after six days of dosing of ASA, a combination of ASA and clopidogrel, or the combination with darexaban ] [ Designated as safety issue: No ]
  • Monitoring of safety and tolerability through assessment of vital signs, Electrocardiogram (ECG), clinical safety laboratory and adverse events [ Time Frame: 6 days for each of the 2 treatment periods ] [ Designated as safety issue: Yes ]
