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 assess Health-Related Quality of Life (HRQoL) in patients newly diagnosed with HLA-A*0201+ H3.3K27M+ DMG.
II. To assess patient and/or proxy satisfaction with study participation via patient-reported outcome (PRO) measures in the context of race ethnicity and other health related social risks.
III To assess on therapy toxicity in the context of race, ethnicity and other health related social risks.
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.
