Expanded/Activated Gamma Delta T-cell Infusion Following Hematopoietic Stem Cell Transplantation and Post-transplant Cyclophosphamide

Acute Myeloid Leukemia Clinical Trial

Official title: Phase I Study of Ex Vivo Expanded/Activated Gamma Delta T-cell Infusion Following Haploidentical Hematopoietic Stem Cell Transplantation and Post-transplant Cyclophosphamide

Clinical Trial Summary

Gamma delta T-cells are part of the innate immune system with the ability to recognize malignant cells and kill them. This study uses gamma delta T-cells to maximize the anti-tumor response and minimize graft versus host disease (GVHD) in leukemic and myelodysplastic patients who have had a partially mismatched bone marrow transplant (haploidentical).

Clinical Trial Description

Many patients with hematological malignancies require a bone marrow transplant for curative treatment. A matched sibling donor is optimal but may not be available. Therefore, a partially matched family member (haploidentical) may be a viable alternative. The incidence of graft vs. host disease, however, can become more of a significant, even fatal, factor with partial matches.

T-cells have been shown to be the key player in the post-transplant immune phenomena. The majority of T-cells are composed of alpha beta T-cells with a small minority of gamma delta T-cells, which are known to have the unique ability to kill malignant cells without antigen recognition.

This study proposes to extract, concentrate, and activate gamma delta T-cells from the peripheral blood to provide innate anti-tumor effect with minimal risk of GVHD. Safety and impact and/or the rate of GVHD will be evaluated. ;
