Brief Summary:
This phase I, first-in-human trial tests the safety, side effects, and best dose of genetically modified cells called KIND T cells after lymphodepletion (a short dose of chemotherapy) in treating patients who are HLA-A*0201-positive and have H3.3K27M-mutated diffuse midline glioma. KIND T cells are a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory into KIND T cells so they will recognize certain markers found in tumor cells. Drugs such as cyclophosphamide and fludarabine are chemotherapy drugs used to decrease the number of T cells in the body to make room for KIND T cells. Giving KIND T cells after cyclophosphamide and fludarabine may be more useful against cancer compared to the usual treatment for patients with H3.3K27M-mutated diffuse midline glioma (DMG).

Condition or disease Intervention/treatment Phase
Diffuse Midline Glioma, H3 K27M-Mutant Drug: Cyclophosphamide Drug: Fludarabine Biological: Autologous Anti-H3.3K27M TCR-expressing T-cells Phase 1

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of a single intravenous (IV) infusion of autologous anti-H3.3K27M T-cell receptor (TCR) -expressing T-cells (KIND T cells) in HLA-A*0201+ participants with H3.3K27M+ diffuse midline gliomas.

II. To determine the safety profile of a single intravenous (IV) infusion of KIND T cells in HLA-A*0201+ participants with H3.3K27M+ diffuse midline gliomas.

SECONDARY OBJECTIVES:

I. To evaluate manufacturing feasibility of KIND T cells.

II. To characterize KIND T cells with respect to their expansion and persistence.

EXPLORATORY OBJECTIVES:

I. To describe anti-tumor responses and survival after infusion of KIND T cells.

II. To explore the association of tumor and immune biomarkers including but not limited to characterization of KIND T cells in blood and tumor samples with clinical endpoints and/or adverse events (AEs).

OUTLINE: This is a dose-escalation study of KIND T cells.

CONDITIONING REGIMEN: Patients receive fludarabine intravenously (IV) on days -4, -3, and -2 and cyclophosphamide IV on day -2 in the absence of disease progression or unacceptable toxicity.

T CELL THERAPY: Patients receive KIND T cells IV over 10 minutes on day 0.

After completion of study treatment, patients are followed up at day 1, 3, 7, 10, 14, 21, and 28, weeks 8-24 and 28-92, months 24-36, and then yearly until year 15.

Arm Intervention/treatment
Experimental: Treatment (KIND T cells, cyclophosphamide, fludarabine)
Patients receive fludarabine IV on days -4, -3, and -2 and cyclophosphamide IV on day -2 in the absence of disease progression or unacceptable toxicity for the conditioning regimen. Patients also receive KIND T cells IV at dose level 1 (2 x 106 dextramer®+ CD8+ cells/kg) on day 0.

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) [ Time Frame: Up to 28 days following infusion of autologous anti-H3.3K27M TCR-expressing T-cells (KIND T cells) ]
    MTD is defined as the dose at which fewer than one-third of participants experience a dose limiting toxicity (DLT) for all participants who received at least one study intervention.

  2. Number of participants with treatment-emergent adverse events [ Time Frame: Up to 24 months ]
    Treatment-emergent adverse events will be graded according to severity, and their incidence will be summarized by dose level.


Secondary Outcome Measures :
  1. Percentage of participants who receive KIND T cells [ Time Frame: Up to 12 months ]
    The percentage of participants who received KIND T cell infusions will be reported. If the manufacturing of T-cell product is not successful because it does not meet release criteria, the participant will have the choice of a second apheresis for a second manufacturing process

  2. Duration of KIND T cells in-vivo persistence [ Time Frame: Up to 12 months ]
    The duration of KIND T cells in-vivo persistence will be estimated using Kaplan-Meier techniques. In addition, the persistence of KIND T cells will be evaluated for each participant for up to 12 months or until any 2 sequential negative tests documenting loss of KIND T cells in blood.
