No electrocardiographic abnormalities within 28 days before enrollment that would clinically preclude the execution of the study, as judged by the investigator.~10. Voluntary written informed consent.~Exclusion Criteria:~1. Serious drug hypersensitivity or a history of drug allergy~2. Active double cancer~3.

Patient with a past history of thrombosis, cerebral infarction, myocardial infarction, or pulmonary embolism~16. Major surgical procedure, open biopsy, or clinically significant traumatic injury within 4 weeks~17. Long-term daily treatment with aspirin (\>325 mg/day)~18. History or evidence of inherited bleeding diathesis or coagulopathy with the risk of bleeding~19. Judged ineligible for participation in the study by the investigator for safety reasons.
