- Known hypersensitivity to any component of bevacizumab

This study will be carried out in two stages. The first stage will enroll a cohort of 22 patients. The FDA will review safety data of the first 15 patients during enrollment of the first cohort. Enrollment and interim analysis of the first cohort of patients will be completed within 15 months of study commencement. Upon FDA approval and favorable interim analysis followed by subsequent protocol/consent amendment (as applicable), the second stage will enroll a cohort of 24 patients and will be completed within 15 months of stage 2 commencement. The overall duration of the study is expected to be no longer than 30 months.

Arms

Experimental: Planned RT + TMZ + BEV + NovoTTF100A Device

Best standard of care radiation therapy (RT, 2 Gy given daily 5 days per week), temozolomide (TMZ, 75 mg/m2 administered daily), and bevacizumab (BEV, 10 mg/kg administered every 2 weeks as an IV infusion) for 6 weeks. After completion of chemoradiation, NovoTTF100A system was initiated, to be worn on average 18 hours or more a day for up to 12 months. The patients also continued with maintenance TMZ/BEV.
