E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary efficacy objective is to evaluate whether dabigatran etexilate is superior to placebo in the long-term prevention of recurrent symptomatic venous thromboembolism (VTE) in patients with symptomatic deep-vein thrombosis (DVT) or pulmonary embolism (PE) who completed 6 to 18 months of treatment with a vitamin K antagonist (VKA). |

E.2.2 | Secondary objectives of the trial | |
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patients with confirmed symptomatic PE or proximal DVT who have been treated for 6 to 18 months with an oral VKA (e.g., warfarin, acenocoumarol, phenprocoumon, or fluindione)
2. Written informed consent
|
|
E.4 | Principal exclusion criteria |
1. Younger then 18 years of age 2. Indication for VKA other than DVT and/or PE 3. Patients in whom anticoagulant treatment for their index PE or DVT should be continued 4. Active liver disease or liver disease decreasing survival (e.g. acute hepatitis, chronic active hepatitis, cirrhosis) or ALAT > 3 x ULN 5. Creatinine clearance < 30 ml/min 6. Acute bacterial endocarditis 7. Active bleeding or high risk for bleeding. 8. Uncontrolled hypertension (investigators judgement) 9. Intake of another experimental drug within the 30 days prior to randomization into the study 10. Life expectancy < 6months 11. Childbearing potential without proper contraceptive measures*, pregnancy or breast feeding *proper contraceptive measures are defined as a method of contraception with a failure rate < 1 % during the course of the study (including the observational period). These methods of contraception according to the note for guidance on non-clinical safety studies for the conduct of human trials for pharmaceuticals (CPMP/ICH/286/95, modification) include consistent and correct use of hormone containing implants and injectables, combined oral contraceptives, hormone containing intrauterine devices, surgical sterilization, sexual abstinence and vasectomy 12. Patients with known hypersensivity to dabigatran or any other component of the investigational product 13. Patients deemed unsuitable for inclusion by the investigator, because considered unreliable to comply with the requirements of the study and/or compliance with study drug administration, or because having any condition or disease which in the opinion of the investigator would not allow safe participation in the study

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The end of trial for each patient is defined as the last clinic visit (visit 9). Visit 9 is 30 days after the last dose of study medication.
But if the number of events is reached before all patients have completed the intended study treatment duration, then the next 3 month visit will be the final visit for all patients and the last included patients will be treated for at least 3 months. All patients will have a 30-day observational period after cessation of study treatment. |
