Description:
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.

Detailed Description
PRIMARY OBJECTIVES:
I. To assess the safety and tolerability of pembrolizumab in combination with standard
therapy (surgery, external beam radiation therapy and temozolomide [TMZ] chemotherapy) in
patients with newly diagnosed glioblastoma multiforme (GBM). (Neoadjuvant [Group 1]) II. To
assess the 18 month overall survival rate of pembrolizumab in combination with standard
therapy (surgery, external beam radiation therapy and TMZ chemotherapy) in patients with
newly diagnosed glioblastoma multiforme (GBM). (Adjuvant [Group 2])
SECONDARY OBJECTIVES:
I. To assess adverse events (AE) and toxicity profile of pembrolizumab in combination with
standard therapy in patients with newly diagnosed GBM.
II. To assess time to progression in patients treated with pembrolizumab in combination with
standard therapy in patients with newly diagnosed GBM. (Adjuvant only) III. To assess
progression-free survival in patients treated with pembrolizumab in combination with standard
therapy in patients with newly diagnosed GBM. (Adjuvant only) IV. To assess time to treatment
failure in patients treated with pembrolizumab in combination with standard therapy in
patients with newly diagnosed GBM. (Adjuvant only)
CORRELATIVE RESEARCH OBJECTIVES:
I. To assess the tumor PD-1/PD-L1 expression and inflammatory microenvironment profile by
comparing PD-1/PD-L1 expression and T lymphocyte/monocytic infiltrates before and after
administration of pembrolizumab treatment. (Neoadjuvant only) II. To assess the peripheral
immunophenotype profile and GBM-associated antigen-specific T cell responses before and after
receiving pembrolizumab treatment in combination with standard therapy.

Primary Outcome Measures
Measure: | Incidence of dose limiting toxicities (DLT) (Group 1) |
Time Frame: | Up to 189 days (3 cycles of treatment) |
Safety Issue: | |
Description: | A 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. The rate of DLTs within each dose-level cohort will be reported along with confidence intervals. |
Secondary Outcome Measures
Measure: | Incidence of adverse events |
Time Frame: | Up to 5 years |
Safety Issue: | |
Description: | The number and severity of all adverse events will be tabulated and summarized in this patient population. Specifically, the overall toxicity percentages for Grade 3 or higher adverse events considered at least possibly related to treatment will also calculated and reported. All other adverse event analysis will be exploratory and hypothesis generating. This may include and not be limited to: a summary of nonhematologic (unspecified) adverse events will be evaluated via the ordinal CTCAE grading, measures of thrombocytopenia, neutropenia, and leukopenia will be assessed using continuous variables as the outcome measures (primarily nadir) as well as categorization via CTCAE grading, overall adverse event incidence as well as profiles by dose level and by tumor type will be explored and summarized. |
