Avastin in Combination With Temozolomide for Unresectable or Multifocal GBMs and Gliosarcomas
Primary objective- To determine efficacy of Avastin, 10 mg/kg every other week, in combination with standard 5-day temozolomide in terms of response rate.
Secondary objective- To determine safety of Avastin & Temozolomide in unresectable glioblastoma patients

- Response Rate [ Time Frame: 4 months ] [ Designated as safety issue: No ]The proportion of subjects with complete or partial response as determined by a modification of the RANO (Response Assessment in Neuro-Oncology) criteria. A confirmation of response was not required. Complete Response was defined as complete disappearance on MR/CT of all enhancing tumor and mass effect, off all corticosteroids (or receiving only adrenal replacement doses), accompanied by a stable or improving neurologic examination, and maintained for at least 4 weeks. Partial Response was defined as greater than or equal to 50% reduction in tumor size on MR/CT by bi-dimensional measurement, on a stable or decreasing dose of corticosteroids, accompanied by a stable or improving neurologic examination, and maintained for at least 4 weeks.

Experimental: Avastin and Temozolomide
Avastin administered at 10 mg/kg every 2 weeks beginning a minimum of 7 days after biopsy or 28 days after craniotomy. Temozolomide dosed at 200 mg/m2 daily for 5 days in a 28-day cycle.
Drug: Avastin and Temozolomide
This is Phase II study with the combination of Avastin & Temozolomide for unresectable or multifocal WHO grade IV malignant glioma patients. Patients will receive up to 4 cycles of Avastin & Temozolomide . Avastin administered at 10 mg/kg every 14 days beginning minimum of 7 days after biopsy or 28 days after craniotomy. Temozolomide will be dosed at 200 mg/m2 daily x 5 days in 28-day cycle. Patients will have baseline MRI & repeat MRI every 4 weeks. If there is no evidence of disease progression after each cycle, or unacceptable toxicity, or as determined by investigators, patient non-compliance or patient withdraws consent to continue therapy & requests discontinuation, patients will receive up to 4 cycles of Avastin & Temozolomide, then proceed with standard XRT therapy, & future therapy after 4 cycles will be at discretion of patient & treating physicians.
