Trial Summary

What is the purpose of this trial?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.

Eligibility Criteria

This trial is for adults with recurrent glioblastoma or gliosarcoma who need reoperation. They must have a certain level of physical function, stable steroid use, and adequate organ function. Women of childbearing age must test negative for pregnancy and agree to contraception; men also need to commit to birth control methods.

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

Experimental Treatment

Group I: Treatment (pembrolizumab, surgery)Experimental Treatment4 Interventions

Patients receive pembrolizumab 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.
