Inclusion Criteria

• Histologically confirmed World Health Organization grade IV malignant glioma (glioblastoma or gliosarcoma)
• First or second progression of glioblastoma/gliosarcoma (according to Response Assessment in Neuro-Oncology [RANO] criteria) following standard of care treatment upon initial diagnosis with radiation
• Measurable disease by RANO criteria at progression
• The maximal tumor volume at baseline meets the following criteria as determined by a local site investigator or surgeon: Longest diameter =< 4 CM
• Surgically resectable disease at progression
• An interval of the following durations prior to randomization: * At least 28 days from prior surgical resection, or 7 days from stereotactic biopsy * At least 12 weeks from prior radiotherapy, unless there is unequivocal histologic confirmation of tumor progression * At least 23 days from prior chemotherapy * At least 42 days from nitrosoureas * At least 42 days from other anti-tumor therapies (including vaccines) * At least 28 days from immune checkpoint blockade * At least 28 days, or 5 half-lives from any investigational agent, whichever is shorter ** NOTE: no wash-out period required from tumor treating field (TTF)
• All clinically significant toxic effects of prior therapy must have recovered to grade 0 or 1 or pre-treatment baseline. Allowable exceptions are: alopecia, lymphopenia, and any laboratory value listed elsewhere in the inclusion criteria (provided it meets that criterion’s requirements). Please contact the overall Principal Investigator, Dr. Patrick Wen, for questions regarding exceptions to this criterion
• Corticosteroid use at or less than dexamethasone 2 mg daily. Participants should be on a stable or decreasing dose for at least 7 days prior to randomization
• Karnofsky performance status (KPS) >= 70%
• Absolute neutrophil count >= 1,500 cells/mL ~ 1.5 K/uL
• Platelets >= 100,000 cells/mL ~ 100 K/uL
• Total bilirubin =< 1.5 X institutional upper limit of normal (ULN) OR direct bilirubin =< institutional ULN for subjects with total bilirubin levels > 1.5 institutional ULN
• Aspartate aminotransferase (AST) =< 2.0 x ULN
• Serum creatinine level =< ULN or creatinine clearance >= 50 mL/min for participants with creatinine levels above normal limits (calculated by the Cockcroft-Gault formula)
• Ability to understand and willingness to sign a written informed consent document
• Availability of 10 unstained formalin-fixed paraffin-embedded slides
• Patients must be able to tolerate magnetic resonance imaging (MRIs)
• MRI within 14 days prior to registration * NOTE: Due to the fact that the screening MRI will not be used for response purpose, participants may be registered if screening MRI is > 14 days of registration if prospective approval is received from Overall PI, Dr. Patrick Wen (for prospectively approved circumstances an eligibility exception will not need to be filed)
• Women of childbearing potential must have a negative serum beta-human chorionic gonadotropin urine or serum pregnancy test within 72 hours prior to registration. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required * NOTE: Women are considered postmenopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms) or six months of spontaneous amenorrhea with serum follicle stimulating hormone (FSH) levels > 40 mIU/mL and estradiol < 20 pg/mL or have had surgical bilateral oophorectomy (with or without hysterectomy) at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential
• Males and females of childbearing potential must utilize a standard contraception method throughout the trial and up to 120 days after the last dose of treatment on study * NOTE: Women of childbearing potential and men with female spouses of childbearing potential must agree to use two methods of reliable contraception simultaneously or to practice complete abstinence from heterosexual contact prior to study entry, while receiving treatment, and for 4 months after undergoing treatment. One method must include a highly effective method such as an intrauterine device, hormonal (birth control pills, injections or implants), tubal ligation or partner’s vasectomy. The other method can be an additional hormonal therapy or barrier method such as a male condom, diaphragm or cervical cap. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in the study, she should inform her treating physician immediately

Exclusion Criteria

• Surgical procedure (including open biopsy, surgical resection, wound revision, or any other major surgery involving entry into a body cavity) or significant traumatic injury within 28 days prior to first study treatment
• Minor surgical procedure (e.g. stereotactic biopsy or shunt placement) within 7 days of first study treatment, placement of vascular access within 2 days of first study treatment
• Expected to have surgery other than the neurosurgical procedure intended for the glioblastoma (GBM) lesion during study treatment period
• Prior stereotactic radiotherapy (Note: those who have had biopsy proven tumor recurrence at a site of stereotactic radiosurgery [SRS] treatment should be considered eligible if approved by the study central investigator)
