E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this study is to demonstrate the superior efficacy of VTE prophylaxis with oral rivaroxaban 10 mg once daily administered for 35 +/- 4 days to SC enoxaparin 40 mg once daily (OD) administered for 10 +/- 4 days in men and women aged 40 years or above who have been hospitalized for a medical illness. The safety of rivaroxaban and enoxaparin will be compared as well. |

E.4 | Principal exclusion criteria |

Up to 2 doses of LMWH or up to 6 doses of unfractionated heparin pre-randomization are allowed. −Systemic treatment with more than 2 doses of strong inhibitors of cytochrome P450 3A4 (CYP 3A4), such as ketoconazole or protease inhibitors, within 4 days before randomization or planned treatment during the time period of the study drug administration −Indication for fibrinolysis or need for continued treatment with antithrombotic agents −Treatment with or use of mechanical thromboprophylaxis (eg, pneumatic compression devices, foot pumps) for VTE prevention −Concomitant conditions or diseases, such as: −Known allergy to rivaroxaban or any of its excipients −Renal dysfunction (ie, calculated creatinine clearance <30 mL/min, see Appendix 10.4 for Cockcroft-Gault formula) −Known significant liver disease (eg, acute hepatitis, chronic active hepatitis, cirrhosis) or LFT abnormalities (confirmed with repeat testing) which would require study medication discontinuation, ie, ALT > 5 x ULN or ALT > 3 x ULN plus total bilirubin > 2 x ULN and the ratio of direct to total bilirubin is >/=50% (see Section 4.3) −Known human immunodeficiency virus (HIV) infection at screening −Systolic blood pressure of >/= 180 mmHg or diastolic pressure of >/=100 mmHg that persists for more than 1 hour at time of screening despite treatment −Anemia (ie, hemoglobin < 10 g/dL) at the time of screening −History of ongoing drug or alcohol abuse −Cardiogenic or septic shock with the need for vasopressor(s), such as noradrenaline, and/or inotropes, such as dobutamine or milrinone −Any severe condition that would limit life expectancy to less than 6 months, ie, advanced malignancy, etc 5.General: −Unilateral or bilateral above knee lower extremity amputation −Inability to take oral medication or otherwise unable or unwilling to undergo/perform study-specified procedures −Have received an experimental drug or used an experimental medical device within 30 days before the planned start of treatment −Pregnancy or breast-feeding or any plan to become pregnant during the study. Women with child-bearing potential not using adequate birth control method (note: as adequate method of birth control oral contraception is recommended. If oral contraception is not feasible, both partners should use adequate barrier birth control). −Previous participation in this study or any other study of rivaroxaban. -Employees of the Center or relatives. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is defined as a composite endpoint of the following components: −Asymptomatic proximal DVT detected by mandatory compression ultrasonography (CUS) at Day 35 + 4 −Symptomatic DVT (proximal or distal) up to Day 35 + 4 −Symptomatic non fatal PE up to Day 35 + 4 −VTE related death up to Day 35 + 4 The major secondary endpoint is defined as the composite of the primary efficacy endpoint (as above), with the addition of all-cause mortality, up to Day 35 + 4 Further secondary endpoints are given by: −Incidence of symptomatic VTE (DVT or PE) up to Day 35 + 4 days −Incidence of each of the components of the primary efficacy endpoint −Incidence of symptomatic VTE during follow-up (up to Day 90 + 7 days) −Incidence of all-cause mortality up to Day 90 + 7 days −Incidence of the composite of cardiovascular death, myocardial infarction or acute ischemic stroke up to Day 35 + 4 days −Incidence of the composite of cardiovascular death, myocardial infarction or acute ischemic stroke during follow-up up to Day 90 + 7 days. −Net clinical benefit as assessed by the composite endpoint comprising the primary efficacy endpoint and treatment-emergent major bleeding or non-major clinically relevant bleeding The analysis of the efficacy endpoints will be solely based on the assessments by the Ultrasonography Adjudication Committee and the Clinical Event Adjudication Committee. |
