Brief Summary
This phase I trial studies the side effects and best dose of EGFR/IL13Rα2 pool-chimeric antigen receptor (CAR) T cells when given through a thin, flexible tube into the brain (locoregional administration) in treating patients with high-grade gliomas that have come back after a period of improvement (recurrent) or that are growing, spreading, or getting worse (progressive). EGFR/IL13Rα2 pool-CAR T cells are a type of CAR T cell therapy. CAR T cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack tumor cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's tumor cells is added to the T cells in the laboratory. The special receptor is called a CAR. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers.

Outcome Measures
Primary Outcomes (2)
Incidence of adverse events
Toxicity will be assessed using the Common Terminology Criteria for Adverse Events version 5.0, Cytokine Release Syndrome/Neurotoxicity grading by the American Society for Transplantation and Cellular Therapy Consensus Criteria, Immune Effector Cell-Associated Hemophagocytic Lymphohistiocytosis-Like Syndrome grading system, and Tumor Inflammation-Associated Neurotoxicity grading system.
Up to 15 years
Maximum tolerated dose (MTD)
The MTD will be determined based on dose limiting toxicities (DLTs), toxicities observed in later cycles (5+), and the activity data. Rate and associated 90% Clopper and Pearson binomial confidence limits (90% confidence intervals \[CI\]) will be estimated for participants experiencing DLTs at the MTD schedule. Tables will be created to summarize all toxicities and side effects by dose, time post treatment, organ, severity, attributions, and arm.
Up to 5 years
Secondary Outcomes (4)
Disease response
Up to 15 years
Time to progression
From surgery/biopsy to last contact or relapse/progression date, assessed up to 15 years
Overall survival (OS)
From surgery/biopsy to last contact or death (from any cause), assessed up to 15 years

Treatment (EGFR/IL13Rα2 pool-CAR T cell therapy)
EXPERIMENTALPatients undergo leukapheresis followed by surgical resection, biopsy, and ICT and/or ICV catheter placement 1-3 weeks prior to cycle 1, day 0. Patients then receive EGFR/IL13Rα2 pool-CAR T cells via ICT and/or ICV catheter over 5 minutes on day 1 of each cycle. Cycles repeat every 7 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients may receive additional cycles of EGFR/IL13Rα2 pool-CAR T cells per PI and patient discretion and/or undergo additional leukapheresis as needed on study. Patients also undergo ECHO during screening, as well as FDG-PET, MRI, and blood, TCF, and CSF sample collection throughout the study.

Eligibility Criteria
You may qualify if:
- Documented informed consent of the participant and/or legally authorized representative.
- Agreement to allow the use of archival tissue from diagnostic tumor biopsies. If unavailable, exceptions may be granted with Study PI approval.
- Age 18 years and older.
- KPS ≥ 70%, ECOG ≤ 2 (Appendix A).
- Life expectancy ≥ 4 weeks.
- Participant has a prior histologically confirmed diagnosis of a glioblastoma (IDH-wildtype) or grade 4 IDH-mutant astrocytoma, or has a prior histologically confirmed diagnosis of a grade 2 or 3 astrocytoma and now has radiographic progression consistent with grade 4 IDH-mutant astrocytoma.
- Relapsed disease: radiographic evidence of recurrence/progression of measurable disease after standard therapy (such as temozolomide with or without Optune device), and ≥ 12 weeks after completion of front-line radiation therapy.
- COH Clinical Pathology assessment at the initial tumor presentation or recurrent disease (reference Appendix B):
- IL13Rα2+ expression by IHC \> 20, and
- EGFR gene-altered by NGS or FISH analysis
- No known contraindications to leukapheresis, steroids, imaging studies, or tocilizumab.
- WBC \> 2000 /dl (or ANC ≥ 1,000/mm3)
- Platelets ≥ 75,000/mm3
- Hemoglobin \> 8g/dL
- Total bilirubin ≤ 1.5x ULN
- +7 more criteria
You may not qualify if:
- Owing to higher frequency of wound-related complications, participants who require active bevacizumab therapy at the time of enrollment are excluded.
- Participant has not yet recovered from toxicities of prior therapy.
- Participant has received any live vaccine within 30 days prior to enrollment.
- Uncontrolled seizure activity and/or clinically evident progressive encephalopathy.
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent.
- Clinically significant uncontrolled illness.
- Active autoimmune disease requiring systemic immunosuppressive therapy
- Known history of immunodeficiency virus (HIV) or hepatitis B or hepatitis C infection.
- Other active malignancy.
- Females only: Pregnant or breastfeeding.
- Any other condition that would, in the Investigator's judgment, contraindicate the subject's participation in the clinical study due to safety concerns with clinical study procedures.
- Prospective participants who, in the opinion of the Investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics).
