Prevention of Venous Thromboembolic Events


To estimate the dose of PD 0348292 that is equivalent to enoxaparin 30 mg BID for VTE in subjects undergoing an elective, unilateral TKR;To characterize the dose-response of PD 0348292 in subjects undergoing an elective, unilateral TKR with respect to efficacy and safety endpoints;To characterize the pharmacokinetics of PD 0348292 in subjects undergoing an elective, unilateral TKR.

1. Age ?18 years;2. Male or female; if female must meet at least 1 of the following criteria:· Greater than or equal to 2 years postmenopausal or· Surgically sterilized3. Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures;4. Scheduled for an elective, unilateral TKR;5. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial.

1. Females with a total body weight <45 kg or males with a total body weight <57 kg;2. Subjects scheduled for a hemiarthroplasty, surface repair or revisionary surgery of the knee;3. History of DVT, PE, suspected postthrombotic state, intracranial or intraocular bleeding, gastrointestinal bleeding and/or endoscopically verified ulcer disease within the past year;4. History of, or in the opinion of the investigator, potential risk for traumatic or repeated epidural or spinal puncture (refer to spinal/epidural hematomas warning in enoxaparin sodium injection package insert);5. Potential risk of extended use of indwelling epidural catheters for more than 6 hours after surgery or within 2 hours of administration of the first dose of study medication;6. Positive urine dipstick for protein or blood at screening or prior to surgery;7. History of uncontrolled hypertension (systolic blood pressure >160 mm Hg or diastolic>100 mm Hg);8. Clinical laboratory evidence of anemia (hemoglobin level <10.0 g/dL) or thrombocytopenia (platelet count <100x103/µL);9. Constitutional or acquired coagulation disorders that in the investigator’s judgment puts the subject at excessive risk for bleeding.10. Severe renal dysfunction, nephrotic syndrome or dysproteinemias (defined as on dialysis or serum creatinine ?1.8 mg/dL, blood urea nitrogen (BUN) >40 or CLcr <30 mL/min);11. Active hepatic disease (defined as transaminase ? 3 x ULN or bilirubin ?1.5 x ULN) or history of hepatic insufficiency;12. DSM-IV or local standard diagnosis of Substance Related Disorders (meets criteria within the preceding past year);13. Cancer (except for non melanoma skin cancer) or cytotoxic treatment for active malignancy;14. Ischemic stroke or myocardial infarction (MI) within the 3 months prior to randomization;15. Surgery/trauma within 6 months prior to randomization;16. Immobilization (mainly confined to bed during waking hours/nonambulatory) for 3 or more days prior to randomization;17. In the opinion of the clinical investigator, subjects potentially at risk of bleeding after minor interventions such as dental treatment, mole removal, or similar interventions within 6 weeks prior to randomization;18. Significant within the previous year, potential bleeding risks such as recurrent gastrointestinal ulcers, epistaxis, and cystitis;19. Subjects with any condition possibly affecting drug absorption (eg, gastrectomy);20. Anticoagulation/direct thrombin inhibitors/thrombolytic therapy administered or completed within 7 days before surgery or during the entire duration of the study period. Subjects requiring long-term anticoagulation therapy should not be included;· Medications known to affect platelet function or coagulation including: Vitamin K antagonists, unfractionated heparin and derivatives, low molecular weight heparins (LMWH) (except those investigated in the study or used in connection with the intraoperative salvage of RBCs), fondaparinux, desirudin, thrombolytic agents, dipyridamole, sulphinpyrazone, GP IIb/IIIa receptor antagonists, clopidogrel, ticlopidine, nonsteroidal anti-inflammatory drugs (NSAIDs), COX-2 inhibitors, acetyl salicylic acid, and dextran.21. History of significant adverse reaction (eg, heparin- or LMWH-induced thrombocytopenia) to an anticoagulant;22. Hypersensitivity to enoxaparin sodium, heparin, or pork products;23. Known allergy to contrast media or iodine;24. 12-lead ECG demonstrating QTc >450 msec and/or clinically significant abnormalities at screening;25. Previous participation in this study;26. Use of any other investigational agent within 30 days of randomization;27. Any condition, which in the opinion of the investigator, would put the subject at increased risk from participating in the study; or 28. Any medical, social, logistical, or psychological reason, which would preclude successful completion of the study protocol.

The primary efficacy endpoint is the incidence of total venous thromboembolic events (VTE) (proximal or distal deep vein thrombosis DVT, and/or pulmonary embolism PE) as determined by a central laboratory. VTE is defined as any postoperative lower extremity deep vein thrombus, or pulmonary embolism, occurring anytime during the treatment period in a symptomatic subject or within 12 hours of the last treatment dose in an asymptomatic subject.The primary safety endpoint is the incidence of total bleeding (defined as major and/or minor bleeding). Major bleeding is defined as fatal bleeding, a fall in hemoglobin ?20 g/L, requiring transfusion of ?2 units of packed red blood cells (RBCs), or required major urgent surgical intervention performed. Minor bleeding is defined as any bleeding that is symptomatic requiring minor intervention (eg, manual compression, cauterization, irrigation, or compressive packing).
