About this trial

This phase I trial tests the safety, side effects, and best dose of E-SYNC chimeric antigen receptor (CAR) T cells after lymphodepleting chemotherapy in treating patients with EGFRvIII positive (+) glioblastoma. Chimeric antigen receptor (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 the CAR T cells will attack cancer 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 cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor. Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Lymphodepleting chemotherapy with cyclophosphamide and fludarabine before treatment with CAR T cells may make the CAR T cells more effective.

Trial outcomes

Primary outcomes

1

Proportion of participants reporting treatment-emergent adverse events

Treatment-emergent adverse events will be graded by National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0

Time frame
Up to 96 weeks

Secondary outcomes

1

Percentage of participants who successfully receive E-SYNC T cells

The percentage of participants for whom a sufficient quantity of drug product (E-SYNC T cells) could be manufactured from peripheral blood mononuclear cells (PBMC) obtained at apheresis and administered will be reported.

Time frame
Up to 96 weeks
2

The percentage of primed E-SYNC T (Cohort 2 only) cells in TIL versus PBMC will be evaluated

The percentage of primed E-SYNC T cells in tumor-infiltrating lymphocytes (TIL) versus Peripheral blood mononuclear cell (PBMC) will be evaluated using single-cell RNA sequencing as a pilot study and described in 5 participants.

Time frame
Up to 96 weeks
