Brief summary

The goal of this clinical research study is to learn if the combination of bevacizumab and lomustine can help to control glioblastoma. The safety of this combination will also be studied.

Detailed description

The Study Drugs: Bevacizumab is designed to prevent or slow down the growth of cancer cells by blocking the growth of blood vessels. Lomustine is designed to damage the DNA (genetic material of cells) of tumor cells, which may cause the tumor cells to die. Study Groups: If you are found to be eligible to take part in this study, you will be randomly assigned (as in the flip of a coin) to 1 of 2 groups. You will have an equal chance of being in either group. * If you are in Group 1, you will receive a higher dose of bevacizumab. * If you are in Group 2, you will receive lomustine and a lower dose of bevacizumab Study Drug Administration: Each treatment cycle is 42 days. If you are in Group 1: On Days 1, 15, and 29 of every cycle, you will receive bevacizumab by vein over 90 minutes. If you are in Group 2: * On Days 1 and 22 of every cycle, you will receive bevacizumab by vein over 90 minutes. * On Day 3 of every cycle, you will take lomustine by mouth 1 time a day. You should take lomustine at bedtime 1 hour before or 2 hours after your last meal of the day with 1 cup (about 8 ounces) of water. Study Visits: If you are in Group 1 or 2, every 6 weeks: * You will be asked about any drugs you may be taking and if you have had any side effects. * You will have a physical exam, including measurement of your vital signs and weight. * You will have a neurological exam. * Your performance status will be recorded. * You will have an MRI scan. * If you are on anti-seizure drugs, blood (about 1 teaspoon) will be drawn to measure the amount of anti-seizure drugs in your blood. If you are in Group 1: * During Weeks 1-6, blood (about 3 teaspoons) drawn for routine tests 1 time a week. * After Week 6, blood (about 3 teaspoons) will be drawn for routine tests every 2 weeks. * On Weeks 2, 4, and 6, and then every 6 weeks after that, urine will be collected to check your kidney function. If you are in Group 2: * During Weeks 1-6, blood (about 3 teaspoons) drawn for routine tests 1 time a week. * After Week 6, blood (about 3 teaspoons) will be drawn for routine tests every 3 weeks. * On Weeks 3 and 6, and then every 6 weeks after that, urine will be collected to check your kidney function. Length of Study: You may stay on study treatment of lomustine and/or bevacizumab for up to 1 1/2 years. After that, you may continue taking bevacizumab for as long as the study doctor thinks it is in your best interest. You will be taken off study early if the disease gets worse or you experience intolerable side effects. End of Study Treatment Visit: After you are off study treatment, you will have an end of study treatment visit. At this visit, you may have some or all of the following tests and procedures performed: * You will be asked about any drugs you may be taking and if you have had any side effects. * You will have physical exam, including measurement of your vital signs and weight. * Blood (about 3 teaspoons) will be drawn for routine tests. * You will have a neurological exam. * Your performance status will be recorded. Long-Term Follow-up: After the end of study treatment visit, the study staff will call you every 3 months to check how you are doing. Each phone call will take about 5 minutes. This is an investigational study. Bevacizumab and lomustine are FDA approved drugs and commercially available for the treatment of brain tumors. The use of these drugs in this combination is investigational. Up to 102 participants will take part in this study. All will be enrolled at MD Anderson.

Inclusion criteria

1. Signed Informed Consent Form 2. Age \>/= 18 years 3. Histologically confirmed glioblastoma in first, second or third relapse. A pathology report constitutes adequate documentation of histology for study inclusion. Subjects with an initial diagnosis of a lower grade glioma are eligible if a subsequent biopsy is determined to be glioblastoma. The amount of prior systemic therapy for this population is, nevertheless, restricted to three regimens, with one including temozolomide. 4. Radiographic demonstration of disease progression following prior therapy 5. Bi-dimensionally measurable disease with a minimum measurement of 1 cm (10 mm) in one diameter on MRI performed within 14 days prior to registration (Day 1). Baseline MRIs for subjects who underwent salvage surgery after first or second relapse must be obtained \>/= 4 weeks after the procedure. If receiving corticosteroids, subjects must be on a stable or decreasing dose of corticosteroids for \>/= 5 days prior to baseline MRI. 6. Patients having undergone recent resection of recurrent or progressive tumor will be eligible as long as all of the following conditions apply: 1) They have recovered from the effects of surgery. 2) Evaluable or measurable disease following resection of recurrent tumor is not mandated for eligibility into the study. 3) To best assess the extent of residual measurable disease post-operatively, a MRI should be done no later than 96 hours in the immediate post-operative period or 4-6 weeks post-operatively. . 7. An interval of \>/= 4 weeks since surgical resection is required prior to starting protocol therapy. 8. Prior standard radiation for glioblastoma 9. Prior chemotherapy: All first-relapse subjects must have received temozolomide. All second- and third-relapse subjects must have received temozolomide. Patients may not have received prior nitrosoureas. 10. Recovery from the effects of prior therapy, including the following: Four weeks from cytotoxic agents (3 weeks from procarbazine, 2 weeks from vincristine); Four weeks from any investigational agent; One week from non-cytotoxic agents(eg accutane, thalidomide); Eight weeks from radiotherapy to minimize the potential for MRI changes related to radiation necrosis that might be misdiagnosed as progression of disease, or 4 weeks if a new lesion, relative to the pre-radiation MRI, develops that is outside the primary radiation field; Patients may have had gliadel wafers during their original surgery but they must be \>/= 9 months post their original surgery date. 11. Prior therapy with gamma knife or other focal high-dose radiation is allowed, but the subject must have subsequent histologic documentation of recurrence or positron emission tomography (PET) or MR Spectroscopic documentation of tumor, unless the recurrence is a new lesion outside the irradiated field 12. Patients must have adequate bone marrow function (WBC \>/= 3,000/µl, absolute neutrophil count (ANC) \>/= 1,500/mm\^3, platelet count of \>/= 100,000/mm\^3, and hemoglobin \>/= 10 gm/dl), adequate liver function (SGPT \< 3 times normal and alkaline phosphatase \< 2 times normal, bilirubin \<1.5 mg/dl), adequate renal function (creatinine \</= 1.5 mg/dL or creatinine clearance \>/= 60 cc/min/1.73 m\^2) and a urine protein:creatinine ratio of \</=1 before starting therapy. These tests must be performed within 14 days prior to registration. Eligibility level for hemoglobin may be reached by transfusion. 13. Patients must have a Karnofsky performance status (KPS) equal or greater than 60 14. Use of an effective means of contraception in males and in females of childbearing potential. Women of childbearing potential must have a negative β-human chorionic gonadotropin (HCG) pregnancy test documented within 14 days prior to registration. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. 15. Ability to comply with study and follow-up procedures 16. Patients receiving treatment with other antiepileptic medications will not be excluded. Patients should preferably be treated with non-enzyme inducing anti-epileptic medications to avoid any potential interactions with lomustine. However, the use of non-enzyme inducing anti-epileptic medications is not mandatory. If enzyme-inducing antiepileptic drugs are used, monitoring of drug levels should be considered, as considered clinically appropriate by the treating physician. 17. Patients on the following medications will be included: Anticoagulants/Anti-platelets: Patients on stable dose anticoagulants (e.g. warfarin, low molecular-weight heparin) and in-range international normalized ratio (INR) (2-3) are eligible. Patients are allowed to take aspirin, clopidogrel, ticlopidine, Aggrenox, ibuprofen and other NSAIDS. 18. Patients must be willing to forego other cytotoxic and non-cytotoxic drug therapy against the tumor while enrolled in the study. 19. This study was designed to include women and minorities, but was not designed to measure differences of intervention effects. Males and females will be recruited with no preference to gender. No exclusion to this study will be based on race. Minorities will actively be recruited to participate.
