Title: A Phase III, Randomised, Double Blind, Parallel-group Study of the Efficacy and Safety of Oral Dabigatran Etexilate (150 mg Bid) Compared to Warfarin (INR 2.0-3.0) for 6 Month Treatment of Acute Symptomatic Venous Thromboembolism, Following Initial Treatment (5-10 Days) With a Parenteral Anticoagulant Approved for This Indication
Brief Summary: The general aim of this study is to determine the comparative safety and efficacy of dabigatran etexilate 150 mg bid administered orally and warfarin Pro re nata (As needed/PRN) to maintain an International Normalised Ratio (INR) of 2.0-3.0 for 6 month treatment of acute symptomatic VTE.

The primary objective is to investigate the efficacy of dabigatran compared to warfarin during the 6 month treatment period. The investigation of other selected efficacy aspects and safety are regarded as secondary objective of this trial.
