---|---|
Experimental: Arm I (nivolumab, ipilimumab, IL13Ralpha2 CAR T cells)
Patients receive nivolumab intravenously (IV) over 60 minutes and ipilimumab IV over 90 minutes on day -14. Patients then receive IL13Ralpha2 CAR T cells infusion over 5 minutes via Rickham catheter (ICV/intracranital ICT) every week and nivolumab IV over 30 minutes every other week. Treatment repeats weekly for up to 4 cycles in the absence of disease progression or unacceptable toxicity. After cycle 4, patients may receive additional CAR T cells weekly and nivolumab IV every other week or monthly at the discretion of the principal investigator and oncologist.

- Incidence of adverse events [ Time Frame: Up to 15 years ]Will assess dose limiting toxicity and all toxicities. Toxicity is the primary endpoint and will be assessed using the National Cancer Institute (NCI)'s Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Rates and associated 95% Clopper and Pearson binomial confidence limits (95% confidence interval [CI]) will be estimated for participants' experiencing dose limiting toxicity (DLT) during neoadjuvant treatment period (DLT period 1), during adjuvant treatment period (DLT period 2), neo-adjuvant and adjuvant feasibility, as well as survival at 9 months. All toxicities and side effects will be summarized in tables by dose, time period, organ, and severity.
- Dose-limiting toxicity (DLT) [ Time Frame: Up to 28 days ]A toxicity that causes side effects that are serious enough to prevent an increase in dose or level of that treatment.
- Feasibility (neoadjuvant therapy) [ Time Frame: Up to 14 days ]As measured by the ability of patients receive ipilimumab/nivolumab (> 80% of the assigned doses) and undergo undergo surgery so that they can go on to receive the first dose of CAR T cells.
- Feasibility (adjuvant therapy) [ Time Frame: Up to 28 days ]Defined as the ability of patients to complete 4 cycles of CAR T infusions (> 80% of the assigned dose) and 2 doses of nivolumab.
- Overall Survival [ Time Frame: At 9 months ]The length of time from either the date of diagnosis or the start of treatment for a disease, such as cancer, that patients diagnosed with the disease are still alive.
- T cell levels [ Time Frame: Up to 15 years ]Will assess chimeric antigen receptor (CAR) T and endogenous T cell levels and phenotype detected in tumor cyst fluid (TCF), peripheral blood (PB), and cerebral spinal fluid (CSF) (absolute number per ul by flow). Statistical and graphical methods will be used to describe persistence and expansion.
- Cytokine levels in TCF, PB, and CSF [ Time Frame: Up to 15 years ]Statistical and graphical methods will be used to describe persistence and expansion.
- Disease response [ Time Frame: Up to 15 years ]By Response Assessment in Neuro-Oncology (RANO) criteria with the need for Avastin as an additional indicator of progression.
- Time to progression [ Time Frame: Up to 15 years ]Progression is defined by RANO with the need for Avastin as an additional indicator of progression.
- Overall survival (OS) [ Time Frame: Up to 15 years ]Kaplan Meier methods will be used to estimate median OS and graph the results.
- Quality of life (QOL) [ Time Frame: Up to 15 years ]Will estimate the mean and standard error for change from baseline during treatment and post treatment in the quality of life functioning scale, symptom scale and item scores from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and the domain scale and items scores from the Quality of Life Questionnaire Brian Tumor Patients 20. Will be estimated for each treatment arm.
- Area under the curve (AUC) for CD3, IFNgamma, and IP-10 levels over time for the DLT evaluation period [ Time Frame: Up to 28 days ]A two-tailed two-sample Students T test with a 0.05 level of significance will be used to determine if the AUCs over the adjuvant treatment DLT period (DLT period 2) for CD3, IFNgamma, and IP-10 are higher in one arm over the other.
- CAR T and endogenous cells detected in tumor tissue [ Time Frame: Up to 15 years ]By immunohistochemistry.
- IL13Ralpha2 antigen expression levels in tumor tissue [ Time Frame: Up to 15 years ]By pathology H score.
- PD-L1 levels on tumor cells [ Time Frame: Pre- and post-therapy ]By flow cytometry
- Biomathematical modeling of tumor growth [ Time Frame: Up to 15 years ]Will assess perfusion and growth parameters based on serial brain magnetic resonance imaging (MRI)s.
- Progression free survival (PFS) [ Time Frame: Up to 15 years ]Kaplan Meier methods will be used to estimate median PFS and graph the results.
