This is an open-label, non-randomized, multicenter Phase 2 study of MEDI4736 with three non-comparative cohorts: Cohort A: 37 subjects with newly diagnosed unmethylated MGMT GBM will receive MEDI4736 every 2 weeks in combination with standard radiotherapy. Cohort B: 30 bevacizumab-naïve subjects with recurrent GBM will receive MEDI4736 every 2 weeks as monotherapy. Cohort B2: 32 bevacizumab-naïve subjects with recurrent GBM will receive MEDI4736 every 2 weeks + bevacizumab every 2 weeks (10 mg/kg). Cohort B3: 32 bevacizumab-naïve subjects with recurrent GBM will receive MEDI4736 every 2 weeks + bevacizumab every 2 weeks (3 mg/kg). Cohort C: 17 bevacizumab-refractory subjects with recurrent GBM will receive MEDI4736 every 2 weeks in combination with continued bevacizumab.
