Engineered immune cells take on deadly brain tumors

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. abilities to understand and the willingness to provide written informed consent; 2. patients are ≥ 2 and ≤ 70 years old; 3. recurrent or refractory brain tumor patients with measurable lesions. Patients have received standard care of medication, such as gross total resection with concurrent radio-chemotherapy (\~54 - 60 Gy, TMZ). Patients must either not be receiving dexamethasone or receiving ≤ 4 mg/day at the time of leukopheresis; 4. Karnofsky performance score (KPS) ≥ 60; 5. life expectancy \>3 months; 6. satisfactory bone marrow, liver and kidney functions as defined by the following: absolute neutrophile count ≥ 1500/mm\^3; hemoglobin \> 10 g/dL; platelets \> 100000 /mm\^3; Bilirubin \< 1.5×ULN; alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \< 2.5×ULN; creatinine \< 1.5×ULN; 7. peripheral blood absolute lymphocyte count must be above 0.8×10\^9/L; 8. satisfactory heart functions; 9. patients must be willing to follow the instructions of doctors; 10. women of reproductive potential (between 15 and 49 years old) must have a negative pregnancy test within 7 days of study start. Male and female patients of reproductive potential must agree to use birth control during the study and 3 months post study. Exclusion Criteria: 1. a prior history of gliadel implantation 4 weeks before this study start or currently receiving antibody based therapies; 2. HIV positive; 3. tuberculosis infection not under control; 4. history of autoimmune disease, or other diseases require long-term administration of steroids or immunosuppressive therapies; 5. history of allergic disease, or allergy to immune cells or study product excipients; 6. patients already actively enrolled in other immune cell clinical study; patients, in the opinion of investigators, may not be eligible or not able to comply with the study.
