* Recent (within 3 weeks of the first infusion of this study) major surgical procedure, biopsy of a parenchymal organ, or significant traumatic injury
* Clinically significant cardiovascular disease (e.g., uncontrolled hypertension \[blood pressure of \>160/110 mmHg on medication\], myocardial infarction, unstable angina), New York Heart Association (NYHA) Grade II or greater congestive heart failure, serious cardiac dysrhythmia requiring medication, or peripheral vascular disease (Grade II or greater)
