Pericardial effusion (except trace effusion identified by echocardiogram) within three months prior to randomization 12. History of brain involvement with cancer, spinal cord compression, or carcinomatous meningitis, or new evidence of brain or leptomeningeal disease. Patients with radiated or resected lesions are permitted, provided the lesions are fully treated and inactive, patients are asymptomatic, and no steroids have been administered for at least 28 days prior to randomization 13. Angina, myocardial infarction, symptomatic congestive heart failure, cerebrovascular accident, transient ischemic attack, arterial embolism , pulmonary embolism, percutaneous transluminal coronary angioplasty (PTCA) or coronary artery bypass graft (CABG) within 6 months prior to randomization.

In this situation, low molecular weight heparin or a direct Factor Xa inhibitor is preferred 14. Active bleeding or pathologic condition that carries a high risk of bleeding (e.g., hereditary hemorrhagic telangiectasia). Patients with bleeding cutaneous lesions not actively requiring transfusions are eligible. Patients who have been uneventfully anti-coagulated with a direct Factor Xa inhibitor or low molecular weight heparin are eligible 15.

| Main Objective: To compare PFS of TRC105 and pazopanib vs single agent pazopanib in patients with unresectable angiosarcoma.;Secondary Objective: • To compare the objective response rate (ORR) of TRC105 and pazopanib vs single agent pazopanib in patients with unresectable angiosarcoma • To compare overall survival (OS) of TRC105 and pazopanib vs single agent pazopanib in patients with unresectable angiosarcoma • To assess the overall safety and tolerability of TRC105 and pazopanib vs single agent pazopanib in patients with unresectable angiosarcoma • To characterize patient reported outcomes between the two arms of the study • To characterize the pharmacokinetic (PK) profile of TRC105 and pazopanib between the two arms of the study • To assess PFS and ORR by Investigator assessment between the two arms of the study • To characterize the immunogenicity of TRC105;Primary end point(s): PFS is defined as time from randomization to either first disease progression (per independent radiology review of images by RECIST 1.1) or death from any cause. For the purpose of analysis for patients who are alive at the time of analysis and have not had disease progression, the following rules will apply: (1) The patient will be censored on the date of the last tumor assessment documenting absence of progressive disease; (2) if the patient was given antitumor treatment other than study drug treatment, the patient will be censored as of the date of the last tumor assessment prior to initiating that antitumor therapy; (3) if the patient was removed from study for toxicity or other reason, the patient will be censored as of the date of the last tumor assessment on study. With regard to missed tumor assessments, in the event of one missed tumor assessment followed by a subsequent assessment of progressive disease (PD), the subsequent PD assessment qualifies as objective tumor progression.

Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • Objective response rate (ORR) is defined as the number of patients with a best response of complete response (CR) or partial response (PR) divided by the number of randomized patients. ORR is defined as the best response designation recorded between the date of randomization and the date of documented progression, as determined by Central Radiographic Review according to RECIST 1.1, or date of subsequent therapy, whichever occurs first. For patients without documented progression or subsequent therapy, all available response designations will contribute to the ORR determination. A designation of CR or PR in this study requires confirmation at a subsequent consecutive assessment at least 4 weeks following the initial designation of CR or PR, respectively. Duration of response (DR) will be reported in patients who achieve ORR, but without a formal statistical comparison between arms. • Overall Survival (OS) is defined as the time between the date of randomization and the date of death from any cause. Overall survival will be calculated in days as: Date of Death – Date of Randomization +1. Subjects alive or lost to follow-up at the time of analysis will be censored at the date when they were last known to be alive. • Type, incidence, severity (graded by National Cancer Institute [NCI] Common Terminology Criteria for Adverse Events [CTCAE] Version 4.03), timing, seriousness, and relatedness of AEs and laboratory abnormalities. • Patient reported outcomes as measured by the EuroQol five dimensions questionnaire (EQ-5D-5L) and the EORTC QLQ-C30 questionnaire. • TRC105 and pazopanib pharmacokinetic (PK) concentrations will be measured using validated methods from peak and trough samples. • Anti-TRC105 antibodies will be measured using validated methods and anti-drug antibody (ADA) titers will be correlated with PK parameters and AEs.;Timepoint(s) of evaluation of this end point: As described in schedule of assessments in protocol. | — |
