In this research study, the investigators are using FMISO-PET and MRI scans to explore the delivery of bevacizumab to the blood vessels in patient's with recurrent glioblastoma before and after treatment.
Bevacizumab is approved by the U.S. Food and Drug Administration for use in patients with recurrent glioblastoma . It works by targeting a specific protein called VEGF, which plays a role in promoting the growth or spreading of tumor blood vessels. Since anti-VEGF agents also affect normal blood vessels in the brain, they can inhibit the way other drugs used in combination with bevacizumab are delivered to the tumor.
In PET scans, a radioactive substance is injected into the body. The scanning machine finds the radioactive substance, which tends to go to cancer cells. For the PET scans in this research study, the investigators are using an investigational radioactive substance called FMISO. "Investigational" means that the role of FMISO-PET scans is still being studied and that research doctors are trying to find out more about it. FMISO goes to areas with low oxygenation so parts of the tumor that do not have enough oxygen can be seen.
In addition, a vascular MRI will be used to evaluate the changes in tumor blood flow, blood volume, and how receptive blood vessels are. This scan will be performed at the same time of the FMISO-PET scan.
This study does not add any additional treatment to patients with malignant glioma who are already scheduled to receive bevacizumab monotherapy. All treatment decisions will be at the discretion of the treating physician. There will be no change in the diagnosis or management of the patient based on any procedures or tests carried out as a part of this study.
If the participant chooses to take part in this research study each treatment cycle will last 28 days.
Day 1-The participant will have the following procedures done before they can receive bevacizumab:
Day 14:The participant will have the following procedures done after they receive bevacizumab:
Day 28: The participant will have the following procedures done after they receive bevacizumab:
FMISO-PET Scans:
The participant will have the scans performed in Charlestown, MA at the Martinos Center. The participant will be injected with two separate intravenous (IV) injections (listed below). Intravenous means a need will be injected into a vein in the participant's arm.
The PET scan will take approximately 60-75 minutes. The participant will receive one injection of FMISO. Following the injection of the radiotracer, blood samples will be taken from the second IV line. The tracer is given through a vein (IV) and travels through the participant's blood and collects in organs and tissues. The participant will need to wait nearby as the tracer is absorbed by the their body. This takes about 90 minutes. Then, the participant will lie on a narrow table that slides into a large tunnel-shaped scanner. The PET will pick up signals from the tracer and a computer will change the signals into 3D pictures that will be displayed on a monitor for the participant's study doctor to read.
MRI Scan:
Planned Follow-up: The investigators would like to call the participant every 3 months for three years after the 28 day visit to see how they are doing and if the participant is experiencing any side effects. If the participant is removed from the study due to an unacceptable side effect, the participant will be followed until it has been resolved.

| Change in Tumor Blood Flow/Perfusion | In this research study, the investigators are using FMISO-PET and MRI scans to explore the delivery of bevacizumab to the blood vessels in patient's with recurrent glioblastoma before and after treatment. | Baseline and day 14 scans |
| Change in Tumor Hypoxic Volume | In this research study, the investigators are using FMISO-PET and MRI scans to explore the delivery of bevacizumab to the blood vessels in patient's with recurrent glioblastoma before and after treatment. Regional hypoxic volume (HV) was determined by thresholding the ratio of the standardized uptake values (SUV) of FMISO in the brain to cerebellum above 1.2. Since some patients had multiple tumors, we identified the HV region within the union of each contrast enhancing region of interest (ROI) and its surrounding FLAIR ROI, so individual tumors could be evaluated separately. HV represents the magnitude of hypoxia within each tumor. | Baseline and day 14 scans |

| Blood Vessel Permeability (Ktrans Change on MRI Scan) | The DCE-MRI data were processed using in-house custom software written in MATLAB to obtain maps of Ktrans based on the 2-parameter Tofts model. Population-level arterial input functions (AIFs) were used for DCE analysis; DCE was used only to calculate Ktrans. Median tumor values for Ktrans were calculated from the contrast enhancing region of interest (ROI). Higher value is more permeability. |

Inclusion Criteria:
Participants must have histologically confirmed glioblastoma and evidence of recurrence. Patients with low-grade tumors who have progressed to glioblastoma are eligible.
Participants must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as > 10 mm. See section 10 for the evaluation of measureable disease.
Only patients for whom their neuro-oncologist has planned to give bevacizumab as monotherapy are eligible for this study
Age > 18 years. Because no dosing or adverse event data are currently available on the use of FMISO in participants <18 years of age, children are excluded from this study but will be eligible for future pediatric trials.
Life expectancy of greater than 3 months.
Karnofsky performance status > 60 (see Appendix A).
Participants must have normal organ and marrow function as defined below:
Patient must be able to undergo MRI and PET scans.
Patients must be maintained on a stable corticosteroid regimen for 5 days prior each MR-PET scan.
The effects of FMISO on the developing human fetus are unknown. For this reason and because radiopharmaceuticals agents are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
Ability to understand and the willingness to sign a written informed consent document.
Exclusion Criteria:
Participants who exhibit any of the following conditions at screening will not be eligible for admission into the study.
History of allergic reactions attributed to compounds of similar chemical or biologic composition to temozolomide or FMISO.
Participants who have already received anti-VEGF or experimental anti-angiogenic therapy for glioblastoma.
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.
Pregnant women are excluded from this study because FMISO is a radiopharmaceutical agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk of adverse events in nursing infants secondary to treatment of the mother with radiopharmaceutical agents, breastfeeding should be discontinued if the mother is treated with radiopharmaceutical agents. These potential risks may also apply to other agents used in this study.
HIV-positive individuals on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with FMISO. In addition, these individuals are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in participants receiving combination antiretroviral therapy when indicated.
Patients who are no suitable to undergo MRI or use gadolinium contrast due to:
