Details and patient eligibility

About

The purpose of this trial is to determine the comparative safety and efficacy of dabigatran etexilate 150 mg bid administered orally and warfarin as needed (pro re nata - prn) to maintain an International Normalised Ratio (INR) of 2.0-3.0 for 6 month treatment of acute symptomatic venous thromboembolism (VTE), following initial treatment (5-10 days) with a parenteral anticoagulant approved for this indication. This trial aims to demonstrate non-inferiority of dabigatran compared with warfarin in patients with acute symptomatic VTE. After achieving non-inferiority, this trial also aims to establish superiority (by means of hierarchical tests) of dabigatran over warfarin.
