Study Details

Study Description

Brief 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.

Detailed 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.

      Proportion of participants for whom a HA-1 TCR T cell product can be administered.

    3. Incidence of dose-limiting toxicities of HA-1 T cell receptor (TCR) T cells [Up to 12 weeks after T-cell infusion]

      Toxicities will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.

    1. Duration of in vivo persistence of transferred HA-1 T cell receptor (TCR) CD4+ T cells in peripheral blood [Up to 1 year]

      Evaluated by tetramer and/or molecular tracking e.g. quantitative polymerase chain reaction (qPCR).

    2. Duration of in vivo persistence of transferred HA-1 T cell receptor (TCR) CD8+ T cells in peripheral blood [Up to 1 year]

      Evaluated by tetramer and/or molecular tracking e.g. qPCR.

    3. Presence, proportion and persistence of HA-1 T cell receptor (TCR) CD4+ T cells in the bone marrow [Up to 1 year]

      Evaluated by tetramer and/or molecular tracking e.g. qPCR.

    4. Presence, proportion and persistence of HA-1 T cell receptor (TCR) CD8+ T cells in the bone marrow [Up to 1 year]

      Evaluated by tetramer and/or molecular tracking e.g. qPCR.

    5. Specific cytolytic activity of HA-1 T cell receptor (TCR) CD8+ and CD4+ T cells against HLA-A*0201+ HA-1+ target cells before adoptive T cell transfer [At the time of T cell infusion (at day 0)]

      Assessed by in vitro chromium release assay or equivalent cytotoxicity assay.

    6. Specific cytolytic activity of HA-1 T cell receptor (TCR) CD8+ and CD4+ T cells against HLA-A*0201+ HA-1+ target cells after adoptive T cell transfer [Up to 1 year]

      By in vitro chromium release assay or flow cytometric degranulation assay (CD107a) using samples of peripheral blood and/or bone marrow collected from patients after adoptive T cell transfer.

    7. Reduction of leukemia in the bone marrow in patients who have measurable leukemia in the marrow prior to HA-1 T cell receptor (TCR) T cell infusion [Up to 1 year]

      Quantified by flow cytometry to determine percentage of leukemic cells in the marrow.

    8. Reduction of recipient normal hematopoietic cells in the bone marrow in patients who have measurable recipient normal hematopoietic cells in the marrow prior to HA-1 T cell receptor (TCR) T cell infusion [Up to 1 year]

      Quantified by variable number tandem repeat (VNTR) to determine percentage of normal recipient and donor cells in the marrow.
