Clinical Trial Summary

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.

Description:

OUTLINE:

This is a dose-escalation study of CD4+ and CD8+ HA-1 TCR T cells.

Patients receive fludarabine for 1-3 doses 3-14 days prior to HA-1 TCR T cell administration. Patients then receive CD4+ and CD8+ HA-1 TCR T cells intravenously (IV) over 1 hour.

After completion of study treatment, patients are followed up closely for 12 weeks and then every 6 months for years 1-5, and every year for years 6-15.

• Patients who have relapsed or have MRD after HCT may receive other agents for treatment of disease and remain eligible for the protocol

• A specific performance status score is not required for enrolling on the protocol; a delay in infusion of the HA-1 TCR T cells may be required for patients with low performance status

DONOR SELECTION INCLUSION

• Donor age >= 18 years

• Donors must be able to give informed consent

• Patients must have an adult donor for HCT who is adequately HLA matched by institutional standards (includes HLA-matched related or unrelated donors, and HLA-mismatched family donors, including haploidentical donors) and is either:

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

• HLA-A*0201 negative

Exclusion Criteria:

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

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

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

• Patients who develop grade IV acute GVHD or severe chronic GVHD following most recent transplant prior to enrollment on the protocol

• The presence of organ toxicities will not necessarily exclude patients from enrolling on the protocol at the discretion of the PI; however, a delay in the infusion of HA-1 TCR T cells may be required

DONOR SELECTION EXCLUSION

• Donors who are HIV-1, HIV-2, human T-lymphotropic virus (HTLV)-1, HTLV-2 seropositive or with active hepatitis B or hepatitis C virus infection

• Unrelated donor residing outside of the United States of America (USA) unless the donor screening, testing and leukapheresis occur at an NMDP-affiliated and qualified donor center and are facilitated by the NMDP.
