About

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.

Full description

OUTLINE:

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

Patients receive lymphodepleting chemotherapy (e.g., fludarabine and cyclophosphamide or debulking regimens as specified in the protocol) ending 2-14 days prior to HA-1 TCR T cell administration. Patients then receive CD4+ and CD8+ HA-1 TCR T cells intravenously (IV).

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.

Initial study activity was funded in part by HighPass Bio, Inc. Current study activity is funded in part by PromiCell Therapeutics, Inc.

Inclusion criteria

  • 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)

  • Subject 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
  • Subjects who are currently undergoing or who previously underwent allogeneic HCT for

    • Acute myeloid leukemia (AML) of any subtype

    • Acute lymphoid leukemia (ALL) of any subtype

    • Mixed phenotype/undifferentiated/any other type of acute leukemia, including blastic plasmacytoid dendritic cell neoplasm

    • Chronic myeloid leukemia with a history of blast crisis and:

      • With relapse or refractory disease (>= 5% marrow blasts, or circulating blasts) at any time after HCT
      • With persistent rising minimal residual disease (defined as detectable disease by morphology, flow cytometry, molecular or cytogenetic testing but < 5% marrow blasts by morphology, no circulating blasts on >= 2 of two consecutive tests), refractory or ineligible for treatment with tyrosine kinase inhibitors at any time after HCT
    • Myelodysplastic syndrome (MDS) of any subtype

    • Chronic myelomonocytic leukemia (CMML)

    • Juvenile myelomonocytic leukemia (JMML)

  • Subjects must be able to understand and be willing to give informed consent; decision-impaired adults may consent with their legally authorized representative; parent or legal representative will be asked to consent for subjects younger than 18 years old

  • Subjects must agree to participate in long-term follow-up for up to 15 years if they are enrolled in the study and receive T cell infusion

  • Subjects 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 subjects with low performance status

DONOR SELECTION INCLUSION

  • Donor age >= 18 years
  • Donors must be able to give informed consent

Exclusion criteria

  • 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
  • The presence of organ toxicities will not necessarily exclude subjects 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 human immunodeficiency virus (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 National Marrow Donor Program (NMDP)-affiliated and qualified donor center and are facilitated by the NMDP
