Summary

This phase I trial studies the side effects and how well IL13Ralpha2-CAR T cells work when given alone or together with nivolumab and ipilimumab in treating patients with glioblastoma that has come back (recurrent) or does not respond to treatment (refractory). Biological therapies, such as IL13Ralpha2-CAR T cells, use substances made from living organisms that may attack specific glioma cells and stop them from growing or kill them. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving IL13Ralpha2-CAR T cells and nivolumab together may work better in treating patients with glioblastoma.

Description

PRIMARY OBJECTIVES:

I. To examine and describe the safety and feasibility of nivolumab plus ipilimumab as neoadjuvant therapy. (Arm 1) II. To examine and describe the safety and feasibility of IL13Ralpha2-CAR T cell plus nivolumab as adjuvant therapy. (Arms 1 and 2) III. To provide IL13R2-CAR T cell therapy for subjects who are unable to wait for randomization into Arms 1 and 2. This arm will provide additional safety data provided in COH IRB 13384 for the set dose schedule. (Arm 3) III. In arms determined to be safe and feasible, a selection design based on two Southwest Oncology Group (SWOG) two stage designs will be used to assess which arm(s) goes on for further study based on survival rate at 9 months.

SECONDARY OBJECTIVES:

I. Describe persistence, expansion and phenotype of endogenous and IL13Ralpha2-CAR CAR T cells in tumor cyst fluid (TCF), peripheral blood (PB), and cerebral spinal fluid (CSF).

II. Describe cytokine levels (PB, TCF, CSF) over the study period for each arm. (Arm 1 or Arm 2).

III. Estimate disease response rates. IV. Estimate time to progression. V. Estimate median overall survival (OS).

VI. In study participants who have completed the adjuvant dose-limiting toxicity (DLT)

period

VIa. Estimate the mean change from baseline in quality of life using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core (QLQ-C)30 and EORTC QLQ Brain Cancer Patients (BN-20) survey scale, domain and item scores during and post treatment.

VIb. Assess if the area under the curve (AUC) for CD3 T cells, IFNgamma and IP-10 for the DLT period is greater in one arm versus (vs.) the other.

VII. In study participants who undergo an additional biopsy/resection or autopsy:

VIIa. Evaluate CAR T cell persistence in the tumor tissue and the location of the CAR T cells with respect to the injection, and VIIb. Evaluate IL13Ralpha2 antigen and PD-L1 levels on tumor tissue pre and post CAR T cell therapy.

VIII. Use biomathematical modeling of tumor growth to evaluate benefit of treatment.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: 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 (intracranial intraventricular [ICV]/intracranial intratumoral [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.

ARM II: Patients receive IL13Ralpha2 CAR T cells infusion over 5 minutes via Rickham catheter (ICV/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.

ARM III: Patients receive IL13Ralpha2 CAR T cells infusion over 5 minutes via Rickham catheter (intracranial intraventricular [ICV]/intracranial intratumoral [ICT]) every 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 at the discretion of the principal investigator and oncologist.

After completion of study treatment, patients are followed up at 30 days, 3, 6, and 12 months, and then annually for 15 years.
