This phase II trial studies how well hypoxia-activated prodrug TH-302 and bevacizumab work in treating patients with glioblastoma multiforme that has grown, spread, or gotten worse after previous bevacizumab therapy. Drugs used in chemotherapy, such as hypoxia-activated prodrug TH-302, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of tumor cells by blocking the growth of new blood vessels necessary for tumor growth. Giving hypoxia-activated prodrug TH-302 and bevacizumab may be an effective treatment for glioblastoma multiforme.

PRIMARY OBJECTIVES:
I. To assess the safety of TH-302 (hypoxia-activated prodrug TH-302) in combination with bevacizumab for patients with high grade glioma.
II. To determine the proportional progression-free survival (PFS) at 4 months for patients treated with combination bevacizumab and TH-302 following recurrence on single agent bevacizumab.
SECONDARY OBJECTIVES:
I. To evaluate overall survival of patients for patients treated with combination bevacizumab and TH-302 following recurrence on single agent bevacizumab.
II. To assess preservation of quality of life (QOL) using the MD Anderson Symptom Inventory for Brain Tumors (MDASI-BT).
TERTIARY OBJECTIVES:
I. To explore the extent of tumor hypoxia and cerebral blood flow in vivo via 18F-fluoromisonidazole (18F-FMISO) positron emission tomography with correlation to patient response and survival.
II. To explore the role of emerging biomarkers of hypoxia in predicting response to TH-302 and overall survival.
OUTLINE:
Patients receive hypoxia-activated prodrug TH-302 intravenously (IV) over 30-60 minutes and bevacizumab IV over 30-60 minutes on days 1, 15, and 29. Courses repeat every 42 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year.
