About this trial

This phase I trial studies the side effects and best dose of CD4+ and CD8+ HA-1 T cell receptor (TCR) (HA-1 T TCR) T cells in treating patients with acute leukemia that persists, has come back (recurrent) or does not respond to treatment (refractory) following donor stem cell transplant. T cell receptor is a special protein on T cells that helps them recognize proteins on other cells including leukemia. HA-1 is a protein that is present on the surface of some peoples' blood cells, including leukemia. HA-1 T cell immunotherapy enables genes to be added to the donor cells to make them recognize HA-1 markers on leukemia cells.

Eligibility criteria

Qualifiers

Subject age 0-80 years at the time of enrollment.

Subject must express HLA-A*0201

Subject must have the HA-1(H) genotype (RS_1801284: A/G, A/A)

HLA-A*0201 positive and HA-1(H) negative (RS_1801284: G/G) or

Disqualifiers

Medical or psychological conditions that would make the subject unsuitable candidate for cell therapy at the discretion of the principal investigator (PI)

Fertile subjects unwilling to use contraception during and for 12 months after treatment

Subjects with a life expectancy of < 3 months of enrollment from coexisting disease other than leukemia

Subjects who have ongoing grade IV acute GVHD or severe chronic GVHD following most recent transplant. Exception: the principal investigator (PI) may make an exception on a case-by-case basis to include such a subject if there is doubt surrounding the GVHD diagnosis and/or sustained significant improvement in GVHD severity
