Title: Oral Direct Factor Xa Inhibitor Rivaroxaban in Patients With Acute Symptomatic Deep-Vein Thrombosis or Pulmonary Embolism
Brief Summary: This is a multicenter, randomized, open-label, assessor-blind, event-driven, non-inferiority program for efficacy with a study treatment duration of 3, 6 or 12 months in patients with confirmed acute symptomatic pulmonary embolism (PE) with or without symptomatic Deep-Vein Thrombosis (DVT) (Einstein-PE).


Options:
A: Inclusion criteria

3. Written informed consent for study participation

Exclusion criteria

1. Overt symptoms of VTE for longer than 2 weeks prior to enrolment
2. PE satisfying at least one of the following criteria: Haemodynamic instability, embolectomy is indicated or performed, thrombolytic therapy is indicated or performed, or suspected source of PE is other than the legs
3. Actual or anticipated use of vena cava filter
4. Contraindications to anticoagulant therapy
5. Patients who in the investigators opinion should not be treated with warfarin
6. Allergy to heparins or other alternate approved therapy used for initial treatment, warfarin or dabigatran, or to one of the excipients included in these medications

8. Known anaemia
9. Need of anticoagulant treatment for disorders other than VTE
10. Recent unstable cardiovascular disease
11. Elevated AST or ALT \> 2x ULN
12. Liver disease expected to have any potential impact on survival
13. Patients who have developed transaminase elevations upon exposure to ximelagatran
14. Severe renal impairment
15. Women who are pregnant, nursing, or of childbearing potential who refuse to use a medically acceptable form of contraception
16. Participation in another clinical trial with an investigational drug during the last 30 days or previous participation in this study
17. Patients considered unsuitable for inclusion by the investigator
