Background:

GBM refers to a specific kind of brain cancer called glioblastoma. The standard treatment for GBM is radiation plus temozolomide, an oral chemotherapy drug. Pembrolizumab is an immune therapy that is now used to treat other cancers. The addition of pembrolizumab to the standard treatment of radiation and temozolomide has been shown to be well tolerated. Researchers want to see if adding a vaccine made from the person s own tumor will improve the effect of the pembrolizumab. The vaccine which is developed from fresh tumor taken at the time of surgery is called HSPPC-96.

Objectives:

To see if the adding pembrolizumab and HSPPC-96 improves the standard treatment for glioblastoma multiforme.

Eligibility:

Adults at least 18 years old with glioblastoma.

Design:

Participants will be screened with typical cancer tests:

Brain scan

Medical history

Blood and urine tests

Questions about quality of life and symptoms

These tests will be repeated throughout the study.

Participants will have surgery to remove their tumor. A tissue sample from the tumor will be sent to a lab. A vaccine will be made from it.

Some participants will get pembrolizumab and vaccine. Some will get pembrolizumab and placebo. Participants will not know which they get.

Participants will get radiation for 6 weeks.

Participants will take temozolomide by mouth before each treatment.

Participants will get pembrolizumab by IV for 30 minutes 3 times over the radiation cycle.

Participants will keep taking the 2 drugs every few weeks for about a year. Some may take pembrolizumab for an additional year.

Most participants will get the vaccine or placebo after radiation. They will get it 5 times over 6 weeks. Some participants will continue to get the vaccine every few weeks for 1 or 2 years.

Participants will repeat the screening tests when they stop study treatment. They will also have follow-up phone calls.

Eligibility

INCLUSION CRITERIA:

Pre Surgery (Step 1) Inclusion:

-MRI findings consistent with a suspected GBM or a histologically confirmed newly diagnosed GBM that has not been treated and would benefit from further surgical resection. As vaccine needs to be generated from the patient s tumor, patients will need to be identified prior to definitive surgery.

-Preliminary assessment by the neurosurgeons that >80% of the tumor can be resected with an expectation that >7gm of tissue would be resected

- Age greater than or equal to 18 years on day of signing informed consent.

- Karnofsky performance status greater than or equal to 70%.

- Tumor must be supratentorial only.

- Stereotactic biopsy will not be allowed unless there is plans for second surgery to remove greater than or equal to 80 % of the tumor.

- No prior treatment with radiation or chemotherapy for their GBM.

- No prior treatment with carmustine wafers.

Post-Surgery (Step 2) Inclusion:

- Pathology must be a GBM, MGMT promoter region determined to be unmethylated and IDH wild type greater than or equal to 80 % resection of contrast enhanced tumor on post operative MRI and greater than 7 grams of tumor resected are required otherwise patient is ineligible.

- Treatment must be initiated greater than or equal to 14 days and < 6 weeks from surgery.

- Craniotomy site must be adequately healed and free of drainage or cellulitis, and the underlying cranioplasty must appear intact at the time of radiation. Radiation must start within 6 weeks of surgery.

- Dexamethasone dose should be less than or equal to 4 mg/day or steroid equivalent prior to starting treatment. If higher doses are needed, consult with Study Chair.

- Female subjects of childbearing potential should have a negative urine or serum pregnancy within 7 days prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a negative serum pregnancy test will be required.

- Patients must have adequate organ and bone marrow function within 14 days prior to step 2 registration, as defined below:

-- Absolute neutrophil count (ANC) > 1.5 (SqrRoot) 10(9)/L; platelet count > 100 (SqrRoot) 10(9)/L; and hemoglobin (Hb) >9.0 g/dL within 7 days prior to step 2 registration. Note: The use of transfusion or other intervention to achieve Hb greater than or equal to 9.0 g/dL is acceptable.

-- Total bilirubin < 1.5 (SqrRoot) ULN (except in patients diagnosed with Gilbert s disease)

-- AST (SGOT), ALT (SGPT), and alkaline phosphatase (ALP) < 2.5 (SqrRoot) ULN

-- Serum creatinine < 1.5 (SqrRoot) ULN

-- International normalized ratio (INR), prothrombin time (PT), or activated partial thromboplastin time (APTT) as follows: In the absence of therapeutic intent to anticoagulate the patient: INR < 1.5 or PT < 1.5(SqrRoot) ULN or aPTT < 1.5(SqrRoot) ULN. In the presence of therapeutic intent to anticoagulate the patient: INR or PT and aPTT within therapeutic limits (according to the medical standard in the institution) and the patient has been on a stable dose of anticoagulants for at least 2 weeks before registration.

- Females of child-bearing potential (FOCBP) and males must agree to use two adequate contraception methods (give examples, e.g. hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 120 days following completion of therapy. Should a female patient become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Male patients who father a child should notify the treating physician.

NOTE: A FOCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

1. Has not undergone a hysterectomy or bilateral oophorectomy

2. Has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)

- Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study.

- Diagnosis must be made by surgical excision.

- Patients should not be on antibiotics for any infection but post operative antibiotics are allowed if used prophylactically but should be completed prior to starting RT.

EXCLUSION CRITERIA:

Pre-Surgery (Step 1) Exclusion:

-Known history of immunodeficiency (HIV). This medical entity can be exacerbated by PD-1 blockade.

-History of another malignancy in the previous 3 years, with a disease-free interval of < 3 years. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy. Patients who have undergone a bone marrow or stem-cell transplant for any malignancy are excluded.

-Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires chronic systemic steroids or immunosuppressive agents except as noted above. Subjects with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections will not be excluded from the study. Subjects with hypothyroidism stable on hormone replacement or Sjorgen s syndrome will not be excluded from the study.

-Has a history of interstitial lung disease, non-infectious pneumonitis or pneumonitis.

-Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator. Examples include:

--Hypertension (defined as 160/95) that is not controlled on medication

--Ongoing or active infection requiring systemic treatment

--Symptomatic congestive heart failure

--Unstable angina pectoris

--Cardiac arrhythmia
