It directly inhibits factor Xa, a blood component in the pathway which leads to coagulation (clotting of blood cells). It is available as a tablet. The purpose of this study is to compare the safety and efficacy of BAY59-7939 with the safety and efficacy of the licensed drug Enoxaparin. Enoxaparin, a so-called low molecular heparin, is approved and widely used in the area of thromboprophylaxis and will be given once daily subcutaneously. In this study 4 different doses of the investigational drug BAY59-7939 will be tested in comparison to Enoxaparin. You will receive during the study either one of the following BAY59-7939 treatments or Enoxaparin. The following doses of BAY59-7939 will be tested: Dose I ; Dose II, Dose III, Dose IV. This study will run for approximately 7 months in a number of countries. In total, up to 600 patients may participate in this study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Male subjects aged 18 years or above and postmenopausal female subjects\n* Subjects scheduled for elective total knee replacement\n* Subjects written informed consent for participation after receiving detailed written and oral information previous to any study specific procedures\n\nExclusion Criteria:\n\nRelated to medical history:\n\n* Any prior DVT or PE\n* Myocardial infarction (MI), TIA or ischaemic stroke within the last 6 months prior to randomization\n* History of heparin-induced thrombocytopenia, allergy to heparins\n* Intracerebral or intraocular bleeding within the last 6 months prior to randomization\n* History of gastrointestinal disease (e.g. active peptic ulcer) with gastrointestinal bleeding within the last 6 months prior to randomization\n* History or presence of gastrointestinal disease which could result in an impaired absorption of the study drug (e.g. severe active inflammatory bowel disease, short gut syndrome)\n* Amputation of one leg\n\nRelated to current symptoms or findings:\n\n* Heart insufficiency NYHA III-IV\n* Congenital or acquired haemorrhagic diathesis (PT INR/aPTT not within normal limits)including patients with acquired or congenital thrombophilia\n\n * Thrombocytopenia (platelets \\< 100,000/µl)\n * Macroscopic haematuria\n * Allergy to contrast media\n * Severe hypertension (SBP \\> 200mmHg, DBP \\> 100 mmHg)\n * Impaired liver function (transaminases \\> 2 x ULN)\n * Impaired renal function (serum creatinine \\> 1.5 x ULN or decreased creatinine clearance \\< 30ml/min)\n * Active malignant disease\n * Presence of active peptic ulcer or gastrointestinal disease with increased risk of gastrointestinal bleeding\n * Body weight \\< 45 kg\n * Drug- or alcohol- abuse\n\nRelated to current treatment:\n\n* Therapy with oral anticoagulants (e.g. phenprocoumon, warfarin-sodium, heparins and factor Xa inhibitors other than study medication) and fibrinolytic therapy\n* Therapy with acetylic salicylic acid or other thrombocyte aggregation inhibitors (e.g. clopidogrel, dipyridamole and ticlopidine) should be stopped one week before enrollment.
