Bevacizumab and Temozolomide Following Radiation and Chemotherapy for Newly Diagnosed Glioblastoma Multiforme

This is an open-label, single arm, multi-center, phase II study involving 48 subjects with newly diagnosed supra-tentorial GBM. Following surgery, subjects with radiographically evaluable disease will receive external beam radiotherapy (59.4 - 60 Gy in 30 - 33 fractions) with daily temozolomide (75 mg/m2). Two to three weeks later, subjects will begin treatment with temozolomide (150-200 mg/m2 daily for five of 28 consecutive days) in conjunction with Avastin (10 mg/kg, every 14 days).
