• Willing to and capable of providing written informed consent prior to any study related procedures
• Ability and willingness to comply with all study requirements, including scheduled visits, treatment plans, laboratory tests, and other study-related procedures

Exclusion Criteria

• Prior use of any standard or investigational anti-tumor therapy other than surgery
• Planned participation in another study of an investigational agent or investigational device or planned use of any other agent or therapeutic device intended for therapy of glioma
• Infratentorial tumors
• Patients with > 1 cm midline shift on postoperative, baseline brain MRI
• Diffuse leptomeningeal gliomatosis
• Known mutation of the IDH1 or IDH2 genes in the tumor, since glioblastomas with these mutations have different biology and are associated with improved prognosis * Documentation that no IDH1 or IDH2 mutations are present in the tumor by a Clinical Laboratory Improvement Amendments (CLIA) approved laboratory is required prior to initiation of study treatment
• Intracranial hemorrhage grade > 1 not attributable to recent neurosurgery
• Systemic treatment with either immunosuppressive doses of corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration * Subjects on a standard high-dose steroid taper after craniotomy or stereotactic biopsy may have received a higher dose of corticosteroids within 14 days of registration, however must be at a dose < 10 mg daily prednisone or bioequivalent per day within 5 days prior to initiation of study drug * Administration of steroids through a route known to result in a minimal systemic exposure (i.e., intranasal, intraocular, inhaled, topical, or local injection [e.g., intra-articular injection] corticosteroids [< 5% of body surface area]) are permitted in the absence of active autoimmune disease * Subjects requiring adrenal replacement with corticosteroids are eligible if the steroids are at doses =< 10 mg prednisone or bioequivalent per day in the absence of active autoimmune disease * Steroids as premedication for hypersensitivity reactions (e.g., computed tomography [CT] scan premedication) are allowed
• Active autoimmune disease that might deteriorate when receiving an immuno-stimulatory agent; the following conditions are not exclusions (subjects with the following conditions are permitted): * Patients with diabetes type I, vitiligo, residual hypo- or hyperthyroidism due to autoimmune condition only requiring hormone replacement, or psoriasis not requiring systemic immunosuppressive treatment, or autoimmune conditions not expected to recur in the absence of an external trigger
• Prior organ transplantation, including allogeneic stem cell transplantation
• Known history of, or any evidence of active, non-infectious pneumonitis within the last 5 years
• Known severe (National Cancer Institute [NCI]- Common Terminology Criteria for Adverse Events [CTCAE] version [v]4.03 grade 3 or 4) infusion-related allergy or acute hypersensitivity reaction attributed to any monoclonal antibody, any history of anaphylaxis, or uncontrolled asthma (that is, 3 or more features of partially controlled asthma)
• Unable tolerate an MRI, or have a contraindication to MRI
• Active infection requiring systemic therapy
• Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome
• Positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus (HCV antibody) indicating acute or chronic infection
• Vaccination within 4 weeks of the first dose of study drug and while on trials is prohibited except for administration of inactivated vaccines; note: seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist) are live attenuated vaccines, and are not allowed
• Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident / stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (>= New York Heart Association Classification class II), or serious cardiac arrhythmia requiring medication
• Patients with another active cancer (excluding basal cell carcinoma, cervical carcinoma in situ or melanoma in situ); prior history of other cancer is allowed, as long as there was no active disease within the prior 2 years
• All other unstable, severe, or chronic medical or psychiatric conditions including colitis, inflammatory bowel disease, pneumonitis, pulmonary fibrosis, recent (within the past year) or active suicidal ideation or behavior, known alcohol or drug abuse, or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study
