Immune cells engineered to fight deadly childhood brain tumors enter human trials

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. ≥ 2 and ≤ 70 years old; 3. Recurrent or refractory diffuse midline glioma or diffuse intrinsic pontine glioma patients with confirmed H3K27M mutation and documented 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. Must be willing to follow the instructions of doctors; 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; 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.
