Please select the eligibility criteria that correspond to the clinical trial below.
Title: A Phase 3, Randomized, Parallel-Group, Multi-Center, Multi-National Study for the Evaluation of Efficacy and Safety of (LMW) Heparin/Edoxaban Versus (LMW) Heparin/Warfarin in Subjects With Symptomatic Deep-Vein Thrombosis (DVT) and or Pulmonary Embolism (PE).
Brief Summary: Evaluation of heparin/edoxaban tosylate (DU176b) versus heparin/warfarin in preventing recurrence of blood clots in patients with acute symptomatic deep-vein blood clots in the legs and/or blood clots in the lungs.


Options:
A: Inclusion Criteria:

* Male or female subjects older than the minimum legal adult age (country specific);
* Acute symptomatic proximal DVT and/or symptomatic PE confirmed at the site by appropriate diagnostic imaging;
* Able to provide written informed consent

Exclusion Criteria:

* thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent to treat the current episode of DVT and/or PE;
* More than 48 hours pre-treatment with anticoagulant therapy prior to randomization;
* Calculated Creatinine clearance (CrCL) \< 30 mL/min;
* significant liver disease (e.g., acute hepatitis, chronic active hepatitis, cirrhosis) or alanine transaminase (ALT) \>\\= 2 times the upper limit of normal (ULN), or total bilirubin (TBL) x 1.5 times the ULN;
* patients with active cancer for whom long term treatment with (LMW) heparin is anticipated;
* active bleeding or high risk for bleeding contraindicating treatment with (LMW) heparin or warfarin;
* chronic treatment with non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs);
* treatment with aspirin in a dosage of more than 100 mg/per day or dual antiplatelet therapy;
* concurrent treatment with potent P-gp inhibitors;
* subjects with any condition that, as judged by the investigator, would place the subject at increased risk of harm if he/she participated in the study
B: Inclusion Criteria:

* Men and women ≥ 18 years of age;
* Clinical diagnosis of Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE);
* Anticoagulant treatment completed
* No recurrence of Venous Thromboembolism (VTE)

Exclusion Criteria:

* Subjects with indications for long-term treatment with a vitamin K antagonist
* Active bleeding or high risk for serious bleeding
* Short life expectancy
* Uncontrolled high blood pressure
* Impaired kidney or liver function
C: Inclusion criteria Patients with non-valvular atrial fibrillation (AF), at moderate to high risk of stroke, or systemic embolism with at least one additional risk factor (i.e. previous ischemic stroke, TIA, or systemic embolism, left ventricular dysfunction, age \>=75 years, age \>=65 with either diabetes mellitus, history of coronary artery disease or hypertension)

Exclusion criteria

1. Prosthetic heart valves requiring anticoagulation per se, or hemodynamically relevant valve disease that is expected to require surgical intervention during the course of the study
2. Severe, disabling stroke within the previous 6 months, or any stroke within the previous 14 days
3. Conditions associated with an increased risk of bleeding
4. Contraindication to warfarin treatment
5. Reversible causes of atrial fibrillation (e.g., cardiac surgery, pulmonary embolism, untreated hyperthyroidism).
6. Plan to perform a pulmonary vein ablation or surgery for cure of the AF
7. Severe renal impairment (estimated creatinine clearance \<=30 mL/min)
8. Active infective endocarditis
9. Active liver disease
10. Women who are pregnant, lactating, or of childbearing potential who refuse to use a medically acceptable form of contraception throughout the study
11. Anaemia (haemoglobin \<100g/L) or thrombocytopenia (platelet count \<100 x 109/L)
12. Patients who have developed transaminase elevations upon exposure to ximelagatran
13. Patients who have received an investigational drug in the past 30 days or are participating in another drug study
14. Patients considered unreliable by the investigator concerning the requirements for follow-up during the study and/or compliance with study drug administration, has a life expectancy less than the expected duration of the trial due to concomitant disease, or has any condition which in the opinion of the investigator, would not allow safe participation in the study (e.g., drug addiction, alcohol abuse)
15. Any known hypersensitivity to galactose if the warfarin used contains galactose.
D: Inclusion Criteria:

* Men and women ≥ 18 years of age
* Clinical diagnosis of DVT or PE

Exclusion Criteria:

* Contraindications for enoxaparin or warfarin
* Active bleeding or high risk for serious bleeding
* Short life expectancy
* Uncontrolled high blood pressure
* Significantly impaired kidney or liver function
