Arm 1 participants will undergo resection of their tumor. Participants receive half the CHM-1101 dose via Rickham catheters into the tumor cavity and half into the lateral ventricle.

Cycle 1 (28 days) CHM 1101 total dose will be divided across 3 once-weekly administrations.

After Cycle 1, additional cycles may be initiated in the absence of disease progression or unacceptable toxicity provided that the principal investigator and participant agree to continue and if adequate autologous CAR-T doses remain.

This is a phase 1b study to evaluate the safety of chimeric antigen receptor (CAR) T cells with a chlorotoxin tumor-targeting domain (ie, CHM-1101, the study treatment) to determine the best dose of CHM-1101, and to assess the effectiveness of CHM-1101 in treating MMP2+ glioblastoma that has come back (recurrent) or that is growing, spreading, or getting worse (progressive).

This is a phase 1b, multicenter, feasibility/safety study of the dual delivery (administered through both intracavitary/intratumoral \[ICT\] and intraventricular \[ICV\] catheters) of CHM-1101, an autologous chlorotoxin-chimeric antigen receptor (CLTX-CAR) cell product, in participants with recurrent or progressive GBM. The investigational product is identified as CHM-1101 (CLTX(EQ)28ζ/CD19t+ CAR T cells).

PRIMARY OBJECTIVE

• To determine the recommended phase 2 dose (RP2D) for dual ICT and ICV delivery of CHM-1101 in participants with MMP2+ recurrent or progressive GBM.

SECONDARY OBJECTIVES

* To assess the feasibility and safety of dual delivery of CHM-1101.
* To describe the persistence, expansion, immunogenicity, and phenotype of CHM-1101 and endogenous cells tumor cyst fluid (TCF), peripheral blood (PB), and cerebrospinal fluid (CSF).
* In participants who receive at least 2 of the 3 planned doses of CHM-1101 in Cycle 1:

  * Estimate the progression-free survival (PFS) rates
  * Estimate the overall survival (OS) rates
* To evaluate the disease response rate.

Two dose levels investigated, with both dose levels proceeding in parallel. Expansion or de-escalation decision rules are based on a traditional 3+3 clinical study design.

CAR T Cells in Patients With MMP2+ Recurrent or Progressive Glioblastoma

A Phase 1b Study to Evaluate CHM-1101, a CAR T-Cell Therapy With a Chlorotoxin Tumor-Targeting Domain for Patients With Matrix Metallopeptidase 2 Positive (MMP2+) Recurrent or Progressive Glioblastoma Multiforme

Assessed according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 5.0.

Assessed per American Society for Transplantation and Cellular Therapy (ASTCT) consensus grading guideline, evaluating levels and phenotype detected in tumor cyst fluid (TCF), peripheral blood (PB), and cerebrospinal fluid (CSF) (absolute number per µL by flowcytometry).

Assess levels and phenotype detected in tumor cyst fluid (TCF), peripheral blood (PB), and cerebrospinal fluid (CSF) (absolute number per µL by flowcytometry).

Assess level and phenotype detected in TCF, PB, and CSF (absolute number per µL by flowcytometry).

Serum samples will be evaluated for HACA against the CLTX(EQ)28ζ therapeutic agent.

Measured from the date of first infusion of CAR-T cells until the first date when progressive disease (PD) is objectively documented or death from any cause, whichever is earlier.

Measured from the date of first infusion of CAR-T cells until death.

Assessed by modified Response Assessment in Neuro-Oncology Criteria (RANO) criteria.

The proportion of participants who experience a complete response, a partial response, or stable disease that is 3 months or greater in duration.
