The purpose of this study is to determine the optimal dose of BAY 59-7939 and to compare the safety and effectiveness of this new drug with the standard way of treatment of deep vein thrombosis (heparin infusion plus one of the vitamin K antagonists), taking into account new events of thrombosis and pulmonary embolism and bleeding risk.

Primary Outcome Measures:
  • The primary efficacy endpoint was the composite of symptomatic recurrent DVT or symptomatic fatal and non-fatal PE at 12 weeks and deterioration in thrombotic burden, as assessed by CUS and PLS, at baseline and at 12 weeks. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The principal safety outcome is all clinically relevant bleeding (i.e. major bleeding and clinically relevant non-major bleeding) within 12 weeks. [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  • The separate components of the primary efficacy outcome at 12 weeks. [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Confirmed acute symptomatic DVT, i.e. proximal or extensive calf-vein thrombosis involving at least the upper third part of the calf veins, without concomitant symptomatic PE
  • Written informed consent

Exclusion Criteria:

  • Legal lower age limitations (country specific)
  • Thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent to treat the current episode of DVT
  • Other indication for VKA than PE/DVT
  • More than 36 hours pre-randomization treatment with therapeutic dosages of (LMW) heparin or more than a single dose of VKA prior to randomization
  • Participation in another pharmacotherapeutic study within the prior 30 days
  • Creatinine clearance < 30 mL/min, impaired liver function (transaminases > 2 x ULN), or bacterial endocarditis
  • Life expectancy < 3 months
  • Active bleeding or high risk for bleeding contraindicating treatment with (LMW) heparin
  • Uncontrolled hypertension: systolic blood pressure > 200 mmHg and diastolic blood pressure > 110 mmHg
  • Pregnancy or childbearing potential without proper contraceptive measures
  • Any other contraindication listed in the labeling of warfarin, acenocoumarol, phenprocoumon, fluindione, UFH, enoxaparin, or tinzaparin
  • Systemic treatment with azole compounds or other strong CYP3A4 inhibitors (e.g. ketoconazole, fluconazol, itraconazole, HIV protease inhibitors) within 4 days prior to randomization and during the study
