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.

Experimental: 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.

- Overall Survival [ Time Frame: 5 Years ]To assess the effect on overall survival of continuing bevacizumab treatment after disease progression in patients treated with bevacizumab from the time of first diagnosis of grade IV malignant glioma.
- Describe Toxicity [ Time Frame: 5 Years ]
To describe the toxicity of bevacizumab, 10 mg every other week (QOW), in combination with radiation therapy and daily Temodar, followed by bevacizumab and 5-day Temodar with continuation of bevacizumab beyond progression.
For each type of toxicity observed, the maximum grade experienced by each patient will be tabulated overall and for each 6-month period of follow-up.
- Progression-free Survival (PFS) [ Time Frame: 5 Years ]To assess the effect on progression-free survival of continuing bevacizumab treatment after disease progression in patients treated with bevacizumab from the time of initiation of treatment to the first occurrence of progression, or death
