E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the effect of oral (PO) apixaban 2.5 mg BID versus subcutaneous (SC) enoxaparin 40 mg QD on the composite endpoint of adjudicated asymptomatic and symptomatic deep-vein thrombosis (DVT), non-fatal pulmonary embolism (PE) and all cause death during 35 days of double-blind treatment in subjects undergoing elective total hip replacement surgery. |
|
E.2.2 | Secondary objectives of the trial |
1/ compare the effect of oral apixaban 2.5 mg BID vs SC enoxaparin 40 mg QD on the composite of adjudicated proximal DVT, non-fatal PE & VTE-related death during 35 days of DB treatment. 2/ assess the effect of oral apixaban 2.5 mg BID vs SC enoxaparin 40 mg QD on: • composite of adjudicated asymptomatic & symptomatic DVT, non-fatal PE & VTE-related death during 35 days of DB treatment • composite of adjudicated proximal DVT, non-fatal PE and all cause death after 35 days of DB treatment. • single adjudicated endpoints of distal DVT, proximal DVT, non-fatal PE, VTE related deaths, and all-cause death during 35 days of DB treatment • adjudicated major bleeding events during 35 days of DB treatment • composite of adjudicated major and clinically relevant non-major bleeding events during 35 days of DB treatment • adjudicated clinically relevant non-major bleeding during 35 days of DB treatment 3/ assess overall safety & tolerability of both treatment arms |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) Signed written informed consent
Target population 2) Subjects undergoing elective unilateral total hip replacement or a revision of at least one component of a total hip replacement. 3) Subject must be willing and able to undergo bilateral ascending contrast venography. Unless Investigator/radiologist can assure that a bilateral venogram can be performed, subjects exceeding 300 lbs. (136 kg) and/or BMI ≥ 35 kg/m2 are to be excluded because of technical limitations due to body habitus.
Age and Sex 4) Men and women, of any race, at least 18 (or legal age of consent if greater) years of age 5) Women of childbearing potential (WOCBP) must be using an adequate method of contraception to avoid pregnancy throughout the treatment period of the study in such a manner that the risk of pregnancy is minimized. |

Target Disease Exceptions 4) Known or suspected, acquired or bleeding or coagulation disorder in the subject or a first degree relative 5) Known or suspected history of heparin-induced thrombocytopenia 6) Known coagulopathy 7) Active bleeding or at high risk for bleeding
Medical History and Concurrent Diseases 8) Brain, spinal, ophthalmologic, or major surgery or trauma within the past 90 days 9) Active hepatobiliary disease 10) Alcohol and/or substance abuse within the past year 11) Any condition, in the opinion of the Investigator, for which surgery or administration of an anticoagulant is contraindicated
Physical and Laboratory Test Findings 12) Two consecutive blood pressure readings within 15-30 minutes with supine SBP > 180 mm Hg or supine DBP > 105 mm Hg 13) Hemoglobin < 10 g/dL 14) Platelet count < 100,000/mm3 15) Creatinine clearance < 30 mL/min as estimated by the method of Cockcroft and Gault (see protocol Section 6.3.4) 16) Active hepatobiliary disease, based on an ALT or AST > 2xULN or a Total Bilirubin ≥ 1.5xULN (unless an alternative causative factor [e.g., Gilbert’s syndrome] is identified)
Allergies and Adverse Drug Reactions 17) Hypersensitivity to unfractionated heparin (UFH), low molecular weight heparin (LMWH), porcine products, or iodinated contrast medium (for venogram)
Prohibited Treatments and/or Therapies 18) Need for ongoing treatment with a parenteral or oral anticoagulant (e.g., subjects with mechanical valves, warfarin eligible atrial fibrillation) 19) Current use of dextrans or fibrinolytics 20) Treatment with medications affecting coagulation or platelet function unless they can be withdrawn as follows: • Unfractionated heparin, LMWH, warfarin (or any other VKA), glycoprotein IIb/IIIa inhibitors (e.g., abciximab, eptifibatide, tirofiban) within 4 days before surgery • Clopidogrel, ticlopidine, dipyridamole, sulfinpyrazone within 7 days before surgery • Non-selective NSAIDs with a T1/2 greater than 17 hours within 7 days before surgery • Fondaparinux within 7 days before surgery • Acetylsalicylic acid > 165 mg within 4 days before surgery 21) Planned indwelling intrathecal or epidural catheter that can not be removed at least 5 hours prior to first dose of post-operative study drug.
Other Exclusion Criteria 22) Prisoners or subjects who are compulsorily detained 23) Subjects who have been previously randomized into an apixaban clinical trial 24) Administration of any investigational drug currently or within 30 days prior to enrollment into this study |
