Overview
Brief Summary
The purpose of this study is to assess the safety/tolerability/feasibility of pembrolizumab and radiation therapy before surgical resection in patients with recurrent glioblastoma as defined by treatment-related AEs and the number of patients who do not necessitate a delay in surgical resection, and to assess overall survival. The secondary objectives are to assess progression free survival, and to assess the T cell clonality, CD8 T cell activation and Tumor Infiltrating Lymphocyte (TIL) score after treatment

Outcomes
Primary Outcomes
Safety and tolerability measured by the incidence of adverse events, serious adverse events and grade 3 or above treatment related adverse events.
Time Frame: From start of study treatment until confirmation of disease progression, intolerable toxicities, withdrawal of consent. Assessed up to 2 years.
Safety and tolerability measured by the incidence of adverse events, serious adverse events and grade 3 or above treatment related adverse events as assessed per CTCAE, Version 5.0.
Overall survival
Time Frame: From start of study treatment until death, loss to follow-up, or withdrawal of consent. Assessed up to 2 years.
From start of study treatment until death, loss to follow-up, or withdrawal of consent. Subjects who are lost to survival follow-up will not be replaced, and public records may be accessed to assess Overall Survival.
Secondary Outcomes
- Immune action(At baseline, prior to stereotactic radiation therapy, and prior to surgery.)
- Progression free survival(From start of study treatment until until confirmation of disease progression, intolerable toxicities, withdrawal of consent. Assessed up to 2 years.)
