Title: Twice-daily Oral Direct Thrombin Inhibitor Dabigatran Etexilate in the Long-term Prevention of Recurrent Symptomatic Proximal Venous Thromboembolism in Patients With Symptomatic Deep-vein Thrombosis or Pulmonary Embolism.
Brief Summary: The primary efficacy objective is to evaluate whether dabigatran etexilate is superior to placebo in the long-term prevention of recurrent symptomatic venous thrombo-embolism (VTE) in patients with symptomatic deep-vein thrombosis (DVT) or pulmonary embolism (PE) who completed 6 to 18 months of treatment with vitamin K antagonist (VKA).

* Patient was diagnosed with symptomatic multiple myeloma based on standard criteria (9), and has measurable disease, defined as follows: any quantifiable serum monoclonal protein value (generally, but not necessarily, greater than 1 g/dL of IgG M-Protein and greater than 0.5 g/dL of IgA M-Protein) and, where applicable, urine light-chain excretion of \>200 mg/24 hours; measurable plasmacytoma \> 2 cm as determined by clinical examination or applicable radiographs (i.e. MRI, CT-Scan); bone marrow plasma cells\>10%.
