Outcome Measures
Primary Outcome Measures
- Safety of combination retifanlimab and radiation with and without temozolomide as assessed by number of participants who experience adverse events [Up to 2 years]
Number of participants who experience grade 1 or higher adverse events, as defined by Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0).
- Feasibility of combination retifanlimab and radiation with and without temozolomide as assessed by number of participants who experience adverse events [Up to 2 years]
Number of participants who experience grade 1 or higher adverse events, as defined by Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0).
- Maximum Tolerated Dose (MTD) as determined by number of participants with dose limiting toxicities (DLT) [Up to 2 years]
Maximum tolerated dose will be determined by the maximum dose at which the least number of participants experience dose-limiting toxicity. The dose limiting toxicity is defined using the Common Terminology Criteria for Adverse Events (CTCAE).
Secondary Outcome Measures

- Overall Survival [Up to 2 years]
Proportion of participants who achieve survival with methylated or unmethylated methylguanine-DNA-methyltransferase (MGMT)
Other Outcome Measures
- Tumor Response as assessed by immune markers in tumor and blood samples [Up to 2 years]
Analyses may include flow cytometry and immunohistochemistry
