Trebananib in Treating Patients With Advanced Angiosarcoma That Cannot Be Removed by Surgery

Inclusion Criteria

• Patients must have histologically confirmed angiosarcoma that is unresectable
• Patients must have measurable disease per Response Evaluation Criteria in Solid Tumors(RECIST) 1.1, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as >= 2 cm with conventional techniques or as >= 1 cm with spiral computed tomography (CT) scan, magnetic resonance imaging (MRI), or calipers by clinical exam
• Patients must have had = = 70%
• Life expectancy of greater than 3 months
• Leukocytes >= 3,000/mcL
• Absolute neutrophil count >= 1,500/mcL
• Hemoglobin >= 8.5g/dL
• Platelet count >= 60,000/mcL
• Total bilirubin = 40 mL/min per 24-hour urine collection or calculated according to the Cockcroft-Gault formula
• Urinary protein = = grade 2 in severity except alopecia
• Currently or previously treated with AMG 386, or other molecules that inhibit the angiopoietins or Tie2 receptor
• Clinically significant cardiovascular disease within 12 months prior to enrollment/randomization, including myocardial infarction, unstable angina, grade 2 or greater (CTCAE version 4.0) 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
• Major surgery within 28 days prior to enrollment or still recovering from prior surgery
• Treatment within 30 days prior to enrollment with strong immune modulators including, but not limited to, systemic cyclosporine, tacrolimus, sirolimus, mycophenolate mofetil, methotrexate, azathioprine, rapamycin, thalidomide, lenalidomide, and targeted immune modulators such as abatacept (CTLA-4- -Ig),adalimumab, alefacept, anakinra, belatacept (LEA29Y), efalizumab, etanercept, infliximab, or rituximab
• Non-healing wound
• Subject not consenting to the use of highly effective contraceptive precautions (e.g., double barrier method [i.e., condom plus diaphragm]) during the course of the study and for 6 months after administration of the last study medication
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to AMG 386
• History of allergic reactions to bacterially-produced proteins
• Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
• Patients who have not yet completed at least 21 days (30 days for prior monoclonal antibody therapy) since ending other investigational device or drug trials, or who are currently receiving other investigational treatments
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Non-pregnant, non-nursing; Note: Women of child bearing potential must have a pregnancy test, serum based within 7 days prior to registration; this is because AMG 386 is an inhibitor of angiogenesis with the potential for teratogenic or abortifacient effects
• Patients with a history of venous or arterial thromboembolism within 12 months prior to enrollment/randomization should be excluded
