Interventions

To assess the dose-effect relationship of once-daily BAY 59-7939 in the treatment of patients with acute symptomatic deep-vein thrombosis (DVT) using the combination of (LMW) heparin and vitamin K antagonist (VKA) as comparator. To determine the optimum once daily dose of BAY 59-7939 for use in phase III studies. Patients will receive either BAY 59-7939 (20, 30 or 40 mg, once-daily) or the combination of (LMW) heparin/VKA (INR 2.0-3.0). The study duration is 12 weeks followed by an additional
