Have a family history of multiple thrombotic events or a personal history of any venous or arterial thrombotic event including deep vein thrombosis, stroke, myocardial infarction, pulmonary embolus, and peripheral arterial thromboembolic events. Subject has had a positive hepatitis panel (including hepatitis B surface antigen [HBsAg] and hepatitis C virus antibody [anti-HCV] or a positive HIV antibody screen at time of the Screening visit.
