TCRαβ+/CD19+ Depleted Allogeneic Hematopoietic Stem Cell Transplantation for Malignant and Non-malignant Disorders

2019-09-18 03:27:36 | BioPortfolio

Summary

The purpose of this study is to investigate the safety and efficacy of TCRαβ+/CD19+ depleted allogeneic hematopoietic stem cell transplant (HSCT) for malignant and non-malignant disorders in children and adolescent/young adult patients using the CliniMACS® immunomagnetic selection device (Miltenyi Biotec).

Description

Acute graft versus host disease (GVHD) remains a significant cause of morbidity and mortality and is the biggest barrier to successful allogeneic hematopoietic cell transplantation (HSCT) outcomes. Improved methods of acute GVHD prevention are needed. TCRαβ+/CD19+ depletion of allogeneic hematopoietic stem cell products offers an opportunity to limit the risk of acute GVHD by removing TCRαβ+ T cells and CD19+ B cells which participate in acute GVHD initiation and perpetuation. The purpose of this study is to investigate the safety and efficacy of TCRαβ+/CD19+ depleted allogeneic hematopoietic stem cell transplant (HSCT) for malignant and non-malignant disorders in children and adolescent/young adult patients using the CliniMACS® immunomagnetic selection device (Miltenyi Biotec).

Medical and Biotech [MESH] Definitions

The release of stem cells from the bone marrow into the peripheral blood circulation for the purpose of leukapheresis, prior to stem cell transplantation. Hematopoietic growth factors or chemotherapeutic agents often are used to stimulate the mobilization.

Transfer of HEMATOPOIETIC STEM CELLS from BONE MARROW or BLOOD between individuals within the same species (TRANSPLANTATION, HOMOLOGOUS) or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). Hematopoietic stem cell transplantation has been used as an alternative to BONE MARROW TRANSPLANTATION in the treatment of a variety of neoplasms.

A hematopoietic growth factor and the ligand of the cell surface c-kit protein (PROTO-ONCOGENE PROTEINS C-KIT). It is expressed during embryogenesis and is a growth factor for a number of cell types including the MAST CELLS and the MELANOCYTES in addition to the HEMATOPOIETIC STEM CELLS.

Clonal hematopoietic stem cell disorders characterized by dysplasia in one or more hematopoietic cell lineages. They predominantly affect patients over 60, are considered preleukemic conditions, and have high probability of transformation into ACUTE MYELOID LEUKEMIA.

An immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.
