Summary
This partially randomized phase II trial with a safety run-in component studies the side effects and how well bevacizumab given with or without trebananib works in treating patients with brain tumors that have come back (recurrent). Immunotherapy with monoclonal antibodies, such as bevacizumab, may induce changes in the body's immune system and interfere with the ability of tumor cells to grow and spread. Trebananib may stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether giving bevacizumab together with trebananib is more effective than bevacizumab alone in treating brain tumors.
Eligibility Criteria
Inclusion Criteria
- Histologically proven diagnosis of glioblastoma or variants (gliosarcoma, glioblastoma with oligodendroglial features, giant cell glioblastoma); patients will be eligible if the original histology was a lower grade glioma and a subsequent histological diagnosis of glioblastoma or variants is made
- The tumor must be supratentorial; patients with infratentorial disease, spinal cord disease, and/or leptomeningeal disease are excluded
- Patients must have shown unequivocal evidence for tumor progression on the previous treatment regimen (prior to enrollment on this study) by magnetic resonance imaging (MRI) scan of the brain with and without contrast within 14 days prior to registration; the dose of steroids must be stable or decreasing for at least 5 days prior to the scan; patients with tumor progression who then undergo surgical resection prior to enrollment on study may be eligible as long as pathology confirms progressive or recurrent glioblastoma multiforme (GBM) (or variants); for patients who undergo surgical resection, registration on study may not occur any sooner than 28 days from surgery; an MRI scan of the brain with and without contrast is still required within 14 days prior to registration on study but is not required to demonstrate measurable disease or tumor progression after surgery
- Patients unable to undergo MRI because of non-compatible devices can be enrolled, provided computed tomography (CT) scans are obtained and are of sufficient quality; patients without non-compatible devices may not have CT scans performed to meet this requirement
- History/physical examination within 14 days prior to registration
- Karnofsky performance scale >= 70 within 14 days prior to registration
- Patients who have received prior treatment with interstitial brachytherapy, stereotactic radiosurgery, or implanted chemotherapy sources, such as wafers of polifeprosan 20 with carmustine, must have confirmation of progressive disease within 14 days prior to registration based upon nuclear imaging, magnetic resonance (MR) spectroscopy, perfusion imaging, or histopathology
- Leukocytes > 3, 000/mm^3 (within 14 days prior to registration)
- Absolute neutrophil count (ANC) >= 1, 500 cells/mm^3 (within 14 days prior to registration)
- Hemoglobin >= 10.0 g/dL (note: the use of transfusion or other intervention to achieve hemoglobin [Hgb] >= 10.0 g/dL is acceptable) (within 14 days prior to registration)
- Platelets >= 100, 000 cells/mm^3 (within 14 days prior to registration)
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) 60 mL/min/1.73 m^2 (per 24 hour urine collection or calculated according to the Cockcroft-Gault formula) for subjects with creatinine levels above the institutional normal (within 14 days prior to registration)
- Patients with creatinine levels below normal institutional limits are eligible
- Prothrombin time (PT)/international normalized ratio (INR) = 1 cm diameter of blood (including postoperative hemorrhage)
- Gastrointestinal bleeding or any other hemorrhage/bleeding event CTCAE, v. 4 grade 3 or greater within 30 days prior to study entry
- Severe, active co-morbidity, defined as follows:
- Unstable angina and/or congestive heart failure requiring hospitalization within 180 days (6 months) prior to registration
- Transmural myocardial infarction within 180 days (6 months) prior to registration
- History of stroke, cerebral vascular accident (CVA), or transient ischemic attack within 180 days (6 months) prior to registration
- Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration
- Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy at the time of registration
- Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects
- Acquired immune d
