Brief Summary:
This phase II trial studies the effects of pembrolizumab on the body, or pharmacodynamics, in patients with glioblastoma that has come back. 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.

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate immune effector function in resected glioblastoma tissue after treatment with intravenously administered pembrolizumab monotherapy in the neoadjuvant setting in patients with recurrent glioblastoma.

II. To correlate the progression free survival at 6 months (PFS6) with objective increases in the immune effector T cell: regulatory T cell (Treg) ratio in tumor tissue as measured by ex vivo T-cell-specific cytokines profiling.

SECONDARY OBJECTIVES:

I. Comparison of time to progression of last prior therapy to time to progression on pembrolizumab, median duration of response, overall response rate (ORR), and overall survival (OS) and safety.

TERTIARY OBJECTIVES:

I. To identify imaging characteristics associated with immunological changes in tumor following treatment with pembrolizumab.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes on day -21 and day -1, and then undergo surgery on day 0. After 2-3 weeks or recovery from surgery, patients continue to receive pembrolizumab IV over 30 minutes every 3 weeks. Courses repeat every 42 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months.

Primary Outcome Measures :
  1. Progression free survival at 6 months [ Time Frame: At 6 months ]
    Progression free survival at 6 months will be estimated using Kaplan-Meier estimates and associated two-sided 95% confidence intervals.


Secondary Outcome Measures :
  1. Time to progression [ Time Frame: The time from study enrollment until the time of first occurrence of disease progression, relapse, or death due to disease, assessed up to 2 years ]
    Evaluated using the Kaplan-Meier product-limit survival curve methodology. Cox proportional hazard regression will be employed for multivariate analysis.

  2. Overall survival [ Time Frame: Up to 2 years ]
    Evaluated using the Kaplan-Meier product-limit survival curve methodology. Cox proportional hazard regression will be employed for multivariate analysis.

  3. Response rate [ Time Frame: Up to 2 years ]
    Logistic regression will be utilized to assess the effect of patient prognostic factors on the response rate.

  4. Rate of toxicities [ Time Frame: Up to 30 days after completion of study treatment ]
    Logistic regression will be utilized to assess the effect of patient prognostic factors on the toxicity rate.

  5. Changes in peripheral blood mononuclear cells immune response kinetics [ Time Frame: Baseline to up to 24 months ]
    Presented graphically and descriptively at each time point. Changes in the magnitude of the response relative to pretreatment after pembrolizumab therapy will be summarized descriptively. Changes in response between pre-treatment and prior to initiation of course 3 of pembrolizumab will be assessed using the Wilcoxon signed-rank test.

  6. Changes in circulating cytokines to pembrolizumab [ Time Frame: Baseline to up to 24 months ]
    Presented graphically and descriptively at each time point. Changes in the magnitude of the response relative to pretreatment after pembrolizumab therapy will be summarized descriptively. Changes in response between pre-treatment and prior to initiation of course 3 of pembrolizumab will be assessed using the Wilcoxon signed-rank test.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Be willing and able to provide written informed consent/assent for the trial
  • Have histologically confirmed World Health Organization grade IV malignant glioma (glioblastoma or gliosarcoma); participants will be eligible if the original histology was low-grade glioma and a subsequent histological diagnosis of glioblastoma or variants is made
  • Patients must be at first or second relapse and clinically require reoperation for tumor progression within 4 to 6 weeks; Note: relapse is defined as progression following initial therapy (i.e., radiation, chemotherapy, or radiation + chemotherapy); if the participant had a surgical resection for relapsed disease and no anti-tumor therapy instituted for up to 12 weeks, this is considered one relapse; for participants who had prior therapy for a low grade glioma, the surgical diagnosis of a high grade glioma will be considered first relapse
  • Have measurable disease consisting of a minimal volume of 1 cm^3
  • Have provided tissue from an archival tissue sample or newly obtained core or excisional biopsy of a tumor lesion
