Official title

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)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
