Eligibility
Inclusion criteria
Inclusion criteria: 1. Objectively confirmed symptomatic uni- or bilateral DVT of the leg involving proximal veins or PE, treated with approved anticoagulant therapy, or with study drug taken during participation in trial 1160.53, for 3 to 6 months at the time of screening, in patients considered at increased risk of recurrent VTE [proximal veins are: trifurcation area, popliteal, superficial femoral, deep femoral, common femoral and iliac vein] 2. Male or female, being 18 years of age or older 3. Written informed consent for study participation Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: 1. Symptomatic DVT or PE at screening 2. Patients with primary PE with suspected origin other that leg limbs (e.g. upper limbs, right heart). 3. Actual or anticipated use of vena cava filter 4. Interruption of anticoagulant therapy for 2 or more weeks during the 3-6 months of treatment for the prior VTE. 5. Patients who in the investigator’s opinion should not be treated with warfarin 6. Allergy to warfarin or dabigatran, or to one of the excipients included in these medications 7. Patients who in the investigator’s judgement are perceived as having an excessive risk of bleeding 8. Known anaemia (haemoglobin 2x ULN based on the local lab results obtained at screening and prior to randomisation (or central screening lab if available on time) 12. Liver disease expected to have any potential impact on survival (e.g. acute hepatitis, or possibly active hepatitis B, hepatitis C or cirrhosis, but not Gilbert’s syndrome or hepatitis A with complete recovery) 13. Patients who have developed transaminase elevations upon exposure to ximelagatran 14. Severe renal impairment (estimated creatinine clearance = 30 ml/min) 15. Women who are pregnant, nursing or of childbearing potential who refuse to use a medically acceptable form of contraception throughout the study (NOTE: A negative pregnancy test must be obtained for any woman of childbearing potential prior to entry into the study) 16. Participation in another clinical trial with an investigational drug during the last 30 days, except for the RE-COVER trial, or previous participation in this study 17. Patients considered unsuitable for inclusion by the investigator, e.g. because considered unreliable to comply with 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) 18. In case of anticipated study related diagnostic procedures requiring contrast medium (e.g. contrast venography or pulmonary angiography): Elevated serum creatinine, which in the investigator’s opinion contraindicates these examinations Known allergy to radio opaque contrast media or iodine, which in the investigator’s opinion contraindicates these examinations

|---|---|
| Main Objective: To determine the comparative efficacy of dabigatran etexilate (150 mg bid) administered orally and warfarin (to maintain an INR of 2.0-3.0) for the long-term treatment and secondary prevention of symptomatic venous thromboembolism in patients who have been successfully treated with standard doses of an approved anticoagulant for three to six months for confirmed acute symptomatic venous thromboembolism.;Secondary Objective: To determine the comparative safety of dabigatran etexilate (150 mg bid) administered orally and warfarin (to maintain an INR of 2.0-3.0) for the long-term treatment of venous thrombolembolism.;Primary end point(s): Composite of recurrent symptomatic venous thromboembolism (VTE) and deaths related to VTE during the treatment period. VTE is defined as the composite incidence of DVT and PE | — |
