Study Summary

This phase II trial studies the side effects and how well pembrolizumab works in combination with standard therapy in treating patients with glioblastoma. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in the chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy beams to kill tumor cells and shrink tumors. Giving pembrolizumab and standard therapy comprising of temozolomide and radiation therapy may kill tumor cells.

Primary Outcome

A dose limiting toxicity DLT will be defined as an adverse event attributed (definitely, probably, or possibly) to pembrolizumab per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Criteria: Grade 4 or higher neutropenia last at least 7 days. Grade 3 electrolyte alteration, nausea, vomiting, or diarrhea lasting at least 3 days. Grade 3 or higher neurologic toxicity. Toxicities leading to delayed treatment of at least 14 days. Inability to proce
