  • Treatment (CAR T cell therapy) I · EXPERIMENTAL · Arm 1 participants will undergo resection/biopsy of their tumor and placement of a Rickham catheter at the site of the resection/biopsy. Patients receive chlorotoxin (EQ)-CD28-CD3zeta-CD19t-expressing CAR T-lymphocytes NCI SYs via single delivery starting on day 0 for 3 weekly cycles over 28 days. Each treatment cycle begins with one CAR T cell infusion delivered intracranial intratumoral or intracavitary \[ICT\] and lasts for 1 week. Beginning 1 week after cycle 3, patients may continue with CAR T cell treatment per principal investigator and patient discretion. Treatment continues in the absence of disease progression or unacceptable toxicity.
  • Treatment (CAR T cell therapy) II · EXPERIMENTAL · Arm 2 participants will undergo resection/biopsy of their tumor and placement of a Rickham catheter at the site of the resection/biopsy and the lateral ventricle. Patients receive chlorotoxin (EQ)-CD28-CD3zeta-CD19t-expressing CAR T-lymphocytes NCI SYs via dual delivery starting on day 0 for 3 weekly cycles over 28 days. Each treatment cycle begins with two CAR T cell infusions (intracranial intratumoral or intracavitary \[ICT\]) and also into the lateral ventricle (intracranial intraventricular \[ICV\]) and lasts for 1 week. Beginning 1 week after cycle 3, patients may continue with CAR T treatment per principal investigator and patient discretion.

This phase I trial studies the side effects and best dose of chimeric antigen receptor (CAR) T cells with a chlorotoxin tumor-targeting domain in treating patients with MPP2+ glioblastoma that has come back (recurrent) or that is growing, spreading, or getting worse (progressive). Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells.
