This includes current symptoms of partial or complete bowel obstruction, recent (within 6 months) history of fistula or bowel perforation, subjects requiring total parenteral nutrition and continuous hydration History of arterial or venous thromboembolism within 12 months prior to enrollment History of clinically significant bleeding within 6 months prior to enrollment History of central nervous system metastasis Known active or ongoing infection (except uncomplicated urinary tract infection) within 14 days prior to enrollment Currently or previously treated with AMG 386, or other molecules that inhibit the angiopoietins or Tie2 receptor Current or within 30 days prior to enrollment treatment with immune modulators such as systemic cyclosporine or tacrolimus Prior myeloablative high-dose chemotherapy with allogeneic or autologous stem cell (or bone marrow) transplant Clinically significant cardiac disease within 12 months prior to enrollment, including myocardial infarction, unstable angina, grade 2 or greater peripheral vascular disease, cerebrovascular accident, transient ischemic attack, congestive heart failure, or arrhythmias not controlled by outpatient medication or placement of percutaneous transluminal coronary angioplasty/stent Uncontrolled hypertension as defined as diastolic blood pressure > 90 mmHg OR systolic blood pressure > 140 mmHg. The use of anti-hypertensive medications to control hypertension is permitted Subjects with a history of prior malignancy, except: Malignancy treated with curative intent and with no known active disease present for ≥ 3 years prior to enrollment and felt to be at low risk for recurrence by treating physician, Adequately treated non-melanomatous skin cancer or lentigo maligna without evidence of disease Adequately treated cervical carcinoma in situ without evidence of disease Major surgery within 28 days prior to enrollment or still recovering from prior surgery Minor surgical procedures, including placement of tunneled central venous access device, within 3 days prior to enrollment History of allergic reactions to bacterially-produced proteins Hypersensitivity to paclitaxel or drugs using the vehicle cremophor Pregnant (ie, positive beta-human chorionic gonadotropin test) or is breast feeding or planning to become pregnant within 6 months after the end of treatment Subject has known positive test(s) for human immunodeficiency virus (HIV) infection, hepatitis C virus, acute or chronic active hepatitis B infection Any condition which in the investigator's opinion makes the subject unsuitable for study participation Any uncontrolled concurrent illness or history of any medical condition that may interfere with the interpretation of the study results Non-healing wound, ulcer (including gastrointestinal) or fracture Subject has previously been enrolled onto this study Subject will not be available for follow-up assessment Subject has known sensitivity to any of the products to be administered during dosing Subject has any kind of disorder that compromises the ability of the subject to give written informed consent and/or to comply with study procedures
