2. Diagnosis of glioblastoma
3. Eastern Cooperative Oncology Group (ECOG) performance status ≥2

4. Abnormal hematologic values defined as:

   • Hemoglobin level < 9 g/dL
   • Absolute neutrophil count (ANC) < 1500/mm3
   • Platelet count < 100,000/mm3

5. Abnormal kidney, liver, or pancreatic function defined as:

9. Ongoing ≥Grade 2 toxicities related to prior antineoplastic therapy
10. Received continuous systemic steroids at doses greater than 10 mg/day of prednisone or its equivalent within 30 days prior to the first dose of study drug (intermittent dexamethasone given for prophylaxis or treatment of emesis is permitted)
11. Received any immunosuppressive agent (except steroids) within 21 days prior to the first dose of study drug
12. Known hypersensitivity to any component of the PDL192 formulation
