Gliadel, XRT, Temodar, Avastin Followed by Avastin, Temodar for Newly Diagnosed Glioblastoma Multiforme (GBM)
The purpose of this study is to determine the safety and effectiveness of Gliadel wafers at the time of surgery, followed by the combination of radiation, Temodar, and Avastin, and then the combination of Avastin and Temodar, after radiation is complete, on malignant brain tumors.
About six weeks after surgery, subjects will begin standard radiation therapy, a fixed dose of Avastin every 2 weeks, and daily Temodar for the six and a half weeks of radiation. Beginning 2-3 weeks after the last radiation therapy, subjects will be given the same fixed dose of Avastin intravenously (through the vein) every 14 days. They will also be given a higher dose of oral Temodar to take daily the first 5 days of each 28-day study cycle.

- 21-month Overall Survival [ Time Frame: 21 months ]The percentage of participants alive at 21 months after the start of study treatment. Overall survival was calculated from the date study treatment started until the date of death or the date of last follow-up if alive. Kaplan-Meier methods were used to estimate overall survival.
- Median Overall Survival [ Time Frame: 21 months ]Overall survival was defined as the time in months from the start of SRS to the date of death or last contact if alive. Kaplan-Meier methods were used to estimate overall survival.
- Median Progression-free Survival [ Time Frame: 21 months ]Progression-free survival was defined as the time in months from the date study treatment started until the date of progression or the date of death if death occurred before progression, or until the date of last follow-up if alive without progression. Kaplan-Meier methods were used to estimate progression-free survival.
- Unacceptable Toxicity Related to the Treatment Regimen [ Time Frame: 27 months ]The number of patients experiencing unacceptable toxicity defined as the occurrence of ≥ grade 2 CNS hemorrhage or treatment-related grade 4 or 5 non-hematologic toxicity.

Experimental: Gliadel, Radiation Therapy, Avastin, Temodar
Single arm study where patients with newly diagnosed Grade IV malignant glioma will receive Gliadel at the time of resection, followed by radiation therapy (XRT), Avastin, and Temodar for approximately 6 1/2 weeks, followed by Avastin and Temodar post-radiation
Patients will have 1-8 wafers of Gliadel inserted at the time of surgical resection.
Other Name: Gliadel (carmustine wafers)Radiation: Radiation Therapy
At a minimum of four weeks, but not greater than eight weeks post-craniotomy, subjects will be treated with standard radiation therapy.Drug: Avastin
Avastin (10 mg/kg) will be given every 14 days, and will begin a minimum of 42 days post-operatively.
Beginning two to three weeks after the last radiation therapy, but not greater than eight weeks, subjects will be treated with Avastin (10mg/m2) every 14 days.
Other Name: Avastin (bevacizumab)Drug: Temodar
At a minimum of four weeks, but not greater than eight weeks post-craniotomy, subjects will be treated with standard radiation therapy and daily Temodar (75mg/m2) for 6.5 weeks of the radiation. In addition, beginning 2-3 weeks after the last radiation therapy, but not greater than 8 weeks, patients will be treated with 5 day Temodar (200 mg/ m2).
Other Name: Temodar (temozolomide)
