Overview
Brief Summary
Studies which have separately studied bevacizumab for recurrent gliomas and bevacizumab for newly-diagnosed glioma have shown good results and the regimens have been well-tolerated by patients. This study seeks to investigate the use of bevacizumab with the standard therapy (radiation therapy and temozolomide) in newly diagnosed patients, followed by bevacizumab and temozolomide with the continuation of bevacizumab following progression. Two critical questions remain- the role of bevacizumab maintenance and bevacizumab at the time of progression in a patient previously treated with bevacizumab at the time of initial diagnosis.
Detailed Description
Given the possible synergism with irinotecan and bevacizumab for colorectal carcinomas, the combination has been studied in gliomas. In a study of 21 patients, the combination of irinotecan and bevacizumab produced a 43% response rate, with acceptable toxicity. The response rate is significantly higher than irinotecan alone and any other therapy for recurrent glioma. There were two serious adverse events, one intracranial hemorrhage and one bowel perforation. At the Duke Brain Tumor Center, the investigators have treated over 1000 glioblastoma patients with a bevacizumab-containing regimen, and there is marked clinical benefit and acceptable toxicity. Our initial study looking at the combination of bevacizumab and irinotecan for patients with recurrent glioblastoma published in 2007 found impressive response rates and survival and corroborated the earlier experience of Starks-Vance. The investigators completed a study for newly diagnosed glioblastoma that utilized bevacizumab, radiation therapy and temozolomide followed by 6 months of bevacizumab, irinotecan and temozolomide. In addition, the group at University of California at Los Angeles published a study with bevacizumab, radiation therapy and temozolomide followed by 12 months of bevacizumab and temozolomide for newly diagnosed glioblastoma. These two phase II studies reported acceptable toxicity and a suggestion of improved survival compared to historical controls, and led to two large phase III randomized, placebo controlled studies of the addition of bevacizumab for newly diagnosed glioblastoma patients. The current proposal builds on the encouraging results of the addition of bevacizumab to the standard therapy for newly diagnosed glioblastoma patients. Two critical questions remain- the role of bevacizumab maintenance and bevacizumab at the time of progression in a patient previously treated with bevacizumab at the time of initial diagnosis. In addition, a retrospective analysis of data collected at our center from patients with recurrent disease suggests that continuation of bevacizumab at the time of progression may improve overall survival in comparison with cessation of bevacizumab.

- •Treatment with any other investigational agent within 28 days or 2 investigational agent half-lives (whichever is longer) prior to first study treatment;
- •Prior, unrelated malignancy requiring current active treatment with the exception of cervical carcinoma in situ and adequately treated basal cell or squamous cell carcinoma of the skin;
- •Evidence of \> Grade 1 central nervous system (CNS) hemorrhage on post-operative MRI scan, unless repeat MRI or CT performed prior to initiating bevacizumab shows stable grade 1 or resolving (\< grade 1) CNS hemorrhage.
- •Bevacizumab-Specific Exclusion Criteria:
- •Inadequately controlled hypertension (defined as systolic blood pressure \> 150 mmHg and/or diastolic blood pressure \> 100 mmHg) within 28 days of first study treatment;
- •Prior history of hypertensive crisis, hypertensive encephalopathy, reverse posterior leukoencephalopathy syndrome (RPLS);
Arms & Interventions
Bevaczimab, Radiation Therapy, Temozolomide
In Part A, newly-diagnosed patients with Grade 4 malignant gliomas will receive standard radiation therapy, daily Temodar 75mg/M for 6-8 weeks. Bevacizumab will be given concurrently with radiation therapy and Temodar, 10 mg/kg every two weeks. If they are stable at the end of Part A, they will continue to Part B. In Part B patients will receive up to 12 cycles of bevacizumab and Temodar. Bevacizumab will be given on Days 1 and 15 of a 28-day cycle. Temodar will be 200 mg/meter squared daily for 5 days (days 1-5) of each cycle. If they have not progressed, patients will start Part C. In Part C, patients will receive bevacizumab 10mg/kg approximately every 2 weeks or 15 mg/kg approximately every 3 weeks. If patients progress during Part B or C, they will start Part D. In Part D, patients will receive bevacizumab-based therapy containing bevacizumab in combination with a chemotherapy and/or biologic agent, as determined by the Duke treating physician.
