Phase I Study of Adoptive Immunotherapy With CD8+ and CD4+ Memory T Cells Transduced to Express an HA-1-Specific T Cell Receptor (TCR) for Children and Adults With Recurrent Acute Leukemia After Allogeneic Hematopoietic Stem Cell Transplantation (HCT)

Who is this study for? Patients with Acute Myeloid Leukemia, Acute Lymphoid Leukemia, Blastic Plasmacytoid Dendritic Cell Neoplasm, or Chronic Myeloid Leukemia
What treatments are being studied? HA-1 T Cell Receptor T Cells
Status: Recruiting
Location: See location...
Intervention Type: Other, Biological
Study Type: Interventional
Study Phase: Phase 1
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.

View:

• Patient age 0-75 years at the time of enrollment.

• Patients must express HLA-A\*0201

• Patients must have the HA-1(H) genotype (RS\_1801284: A/G, A/A)

• 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

• Patients 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)

• Patients 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 patients younger than 18 years old

• Patients 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

• 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

Treatments
Experimental: Treatment (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 IV.
