NCT01424332

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Composite assessment of pharmacodynamics of darexaban and darexaban glucuronide

    Assessment includes skin bleeding time, factor Xa, platelet aggregation, thromboxane B2 synthesis, PT \& aPTT

    Baseline and after six days of dosing of darexaban, ASA, or a combination of the two

Secondary Outcomes (3)

  • 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

  • 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

  • Any of the liver function tests (i.e. ALT, AST and bilirubin) above the upper limit of normal at repeated measures
  • Any clinically significant history of any other disease or disorder - gastrointestinal, cardiovascular, respiratory, renal, hepatic, neurological, dermatological, psychiatric or metabolic as judged by the medical investigator
  • Any clinically significant abnormality following the investigator's review of the pre-study physical examination, ECG and clinical laboratory tests
  • Use of any prescribed or OTC (over-the-counter) drugs (including vitamins, natural and herbal remedies, e.g. St. John's wort) in the 2 weeks prior to admission to the Clinical Unit, except for occasional use of paracetamol (up to 3 g/day)
  • Regular use of any inducer of liver metabolism (e.g. barbiturates, rifampicin) in the 3 months prior to admission to the Clinical Unit
  • Donation of blood or blood products within 3 months prior to admission to the Clinical Unit
  • Any use of drugs of abuse, or smoking of more than 10 cigarettes (or equivalent) or more than 21 units (210 g) of alcohol per week within the 3 months prior to study
  • Participation in any clinical study within 3 months or participation in more than 3 clinical studies within 12 months, prior to the expected date of enrolment into the study, provided that the clinical study did not entail a biological compound with a long terminal half life
