6. History of venous thromboembolism (eg, deep vein thrombosis, pulmonary embolism,and
arterial thromboembolism) or other indications for anticoagulant treatment
(eg,mechanical heart values, atrial fibrillation, etc.) within the last year. Local
thrombus in the mesenteric or portal vein is acceptable.
7. Uncontrolled hypertension (systolic > 160 or diastolic > 100 mm Hg on medical
treatment).
8. Continued anticoagulation therapy or anticoagulation therapy within 2 months prior to
enrollment, except for perisurgical prophylaxis which must have ceased 2 weeks before
enrollment.
9. Contraindication to systemic anticoagulation.
10. Continued treatment with antiplatelet drugs including aspirin, clopidogrel, etc.
within the past 72 hours.
11. Known history of clinically significant or recurrent bleeding episodes, including
significant bleeding after surgery, childbirth, or dental extraction.
12. Patients with documented invasion of adjacent organs by CT scan (e.g. stomach,
duodenum) are not eligible
13. Patients known to have esophageal varicose are not eligible
14. Known history of a congenital coagulation factor deficiency.
15. Known acquired or hereditary platelet disorder.
16. Known history of immunodeficiency.
17. Women of child-bearing potential or sexually active men, unwilling to use adequate
contraceptive protection during the course of the study.
18. Pregnant or lactating women (female patients of childbearing potential must have a
negative serum pregnancy test within 14 days of first day of drug dosing, or if
positive, pregnancy ruled out by ultrasound).
19. Laboratory Abnormalities:
1. Serum creatinine > 2 mg/dL or creatinine clearance < 50 mL/minute (using
Cockroft Gault formula)
2. AST and ALT ≥ 4.0 x upper limit of normal (ULN).
3. Bilirubin ≥ 3 mg/dL.
4. Alkaline phosphatase > 5 x ULN.
5. Albumin < 2.0g/dL.
6. Hemoglobin < 9.0 g/dL.
7. Platelet count < 100,000/μL.
20. Evidence of active gastrointestinal tract bleeding, including guaiac stool
positivity,excluding hemorrhoidal bleeding
21. Chronic active hepatitis B or C.
22. Known HIV infection.
23. Participation in any study of an investigational device, medication, biologic, or
other agent within 30 days prior to enrollment, or planned participation within the
study duration.
24. Risk factors for, or use of medications known to prolong QTc interval or that may be
associate with Torsades de Pointes within 7 days of treatment start (see Appendix J.
Risk Factors for Drug-induced Torsades de Pointes).
25. QTc prolongation (defined as a QTc ≥ 450 msec) or other significant ECG abnormalities
including 2nd degree AV block type II, 3rd degree AV block, or bradycardia
(ventricular rate less than 50 beats/min). If 2 screening ECGs have a QTc ≥ 450 msec,
the ECGs can be submitted for a centralized, cardiologic evaluation and if determined
to be < 450 msec then the patient is eligible.
