Subjects of child-bearing or child-fathering potential must be willing to use an
effective method of contraception (hormonal or two barrier methods) while on

Prior Therapy
At least 6 weeks following completion of front-line radiation therapy
At least 3 weeks post chemotherapy or 5 half-lives, whichever is shorter must have elapsed since any prior systemic therapy, except for systemic inhibitory/stimulatory immune checkpoint therapy, which requires 5 half-lives
At least 4 weeks from bevacizumab treatment, which can be used only for radiation necrosis or pseudo-progression
Prior cytotoxic chemotherapy, radiation, or other anticancer therapies including investigational agents discontinued at least 4 weeks prior to Day 1 of treatment
Toxicities due to prior therapy must be stable and recovered to ≤ Grade 1 (except for clinically non-significant toxicities such as alopecia)
Pregnant or patients who are breastfeeding
Prior or concurrent treatment with Avastin (bevacizumab) for the purposes of recurrent disease. Avastin (bevacizumab) may have been used for radiation necrosis
Prior exposure to chimeric antigen receptor (CAR) based therapies
Known sensitivity or allergy to any agents/reagents used in this study
Patients receiving anticoagulation therapy
Prior malignancy except previously diagnosed and definitively treated more than 3 years prior to trial or whose prognosis is deemed good enough to not warrant surveillance
Clinical evidence of significant increased intracranial pressure (i.e. impending herniation) or uncontrolled seizures
Presence of fungal, bacterial, viral, or other infection that is uncontrolled or requiring IV antimicrobials for management. Simple UTI and uncomplicated bacterial pharyngitis are permitted if responding to active treatment
Known history of infection with HIV or hepatitis B (HBsAg positive) or hepatitis C virus (anti-HCV positive). A history of hepatitis B or hepatitis C is permitted if the viral load is undetectable per quantitative PCR and/or nucleic acid testing
Primary immunodeficiency or history of autoimmune disease (e.g. Crohn's, rheumatoid arthritis, systemic lupus) resulting in end organ injury or requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years
Significant medical diseases or conditions, including poorly controlled conditions: i.e. hypertension, cardiovascular disease, diabetes mellitus, chronic obstructive pulmonary disease, pulmonary fibrosis, inflammatory disorders, immunodeficiency (e.g., HIV infection), immune compromised for reasons other than malignancy (e.g., chronic corticosteroid therapy or other immunosuppressive therapy), renal failure including patients requiring dialysis, liver dysfunction, second malignancy (except treated basal cell or localized squamous cell skin carcinomas), or active infection
Yes for Significant medical diseases or conditions, including poorly controlled conditions: i.e. hypertension, cardiovascular disease, diabetes mellitus, chronic obstructive pulmonary disease, pulmonary fibrosis, inflammatory disorders, immunodeficiency (e.g., HIV infection), immune compromised for reasons other than malignancy (e.g., chronic corticosteroid therapy or other immunosuppressive therapy), renal failure including patients requiring dialysis, liver dysfunction, second malignancy (except treated basal cell or localized squamous cell skin carcinomas), or active infection exclusion criteria 11
