• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator. Evidence for such abnormalities/conditions will be documented in the patient's medical record.

Note: Patients with either deep vein thrombosis or pulmonary emboli that does not result in hemodynamic instability are allowed to enroll as long as they are on a stable dose of anticoagulants for at least 4 weeks. Also note: Patients with thromboembolic events related to indwelling catheters or other procedures may be enrolled. Finally: patients with stable mesenteric thrombosis that predate study assessment (eg portal vein thrombus) may be enrolled.
• Has a history of active bleeding requiring transfusion within a 3 month period prior to screening. (Transfusions attributed to chemotherapy related anemia do not meet this exclusion criterion.)
