• Age of 16 years or older
• ECOG performance status ≤ 1
• Resolution of all acute adverse events resulting from prior cancer therapies to NCI CTCAE grade ≤ 1 or baseline
• Adequate organ function

Exclusion Criteria

• Male
• Prior treatment with TRC105
• . Current treatment on another therapeutic clinical trial
• Uncontrolled chronic hypertension defined as systolic > 150 or diastolic > 90 despite optimal therapy
• Significant pericardial effusion, pleural effusion, or ascites
• Active bleeding or pathologic condition that carries a high risk of bleeding
• Tumors located in the central chest or other location where bleeding is associated with high morbidity
• Thrombolytic use (except to maintain i.v. catheters) within 10 days prior to first day of study therapy
• Angina, MI, 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 the past 6 months. Deep venous thrombosis within 6 months, unless the patient is therapeutically anti-coagulated for at least 2 weeks. In this situation, low molecular weight heparin is preferred
• Known active viral or nonviral hepatitis
• Pregnant or actively breastfeeding without intention to discontinue prior to initiation of study
• Open wounds or unhealed fractures within 28 days of starting study treatment
• History of peptic ulcer disease or erosive gastritis within the past 6 months, unless treated for the condition and complete resolution has been documented by esophagogastroduodenoscopy (EGD) within 28 days of starting study treatment
• History of gastrointestinal perforation or fistula in the past 6 months, or while previously on antiangiogenic therapy, unless underlying risk has been resolved
• Known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) related illness
• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for this study

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 brain edema for at least 28 days
• Receipt of systemic anticancer therapy, including investigational agents, within 28 days of starting study treatment. If anticancer therapy was given within 28 days of starting study treatment, patients may be included if 5 times the elimination half-life of the drug has passed
• Patients who have received wide field radiotherapy ≤ 28 days (defined as > 50% of volume of pelvic bones or equivalent) or limited field radiation for palliation < 14 days prior to starting study treatment or those patients who have not recovered adequately from side effects of such therapy
• Major surgical procedure or significant traumatic injury within 6 weeks prior to study registration or not fully recovered from any such procedure
