Spots Global Cancer Trial Database for Ex Vivo TCR αβ T Cell Depletion for Graft-Versus-Host Disease Prophylaxis in Mismatched Donor Peripheral Blood Stem Cell Transplantation for Hematologic Malignancies

Study Description

Brief Summary: This research study is studying the removal of a subset of white blood cells (called alpha/beta T cells) from the donor product using a cell separation device before the product is transplanted into the participant. The device used to remove the α/βT cells in this study is: -CliniMACS® TCR α/β Reagent System

Detailed Description: Patients who receive an allogeneic (using another person as the donor) stem cell transplant (SCT) are at risk for developing graft-versus-host disease (GVHD). The word "graft" refers to the donor blood cells that you will receive during the transplant. The word "host" refers to the person receiving the cells. GVHD is a complication of transplantation where the donor graft attacks and damages some of the participant's tissues. GVHD may occur when the T cells (a type of white blood cell that helps protect the body from infection) from the donor react against normal tissues or organs in the body. There are two basic types of GVHD: * Acute GVHD often occurs early (generally first 3-6 months after SCT) may affect skin, gastrointestinal tract (stomach and intestines) and liver. * Chronic GVHD often occurs later (Usually after 3-6 months after SCT) and may affect many organs and significantly diminish quality of life. To confirm the diagnosis of acute or chronic GVHD, the participant may be asked to have a biopsy (a small sample of the participant's tissue to look at under the microscope) of the skin, gut, or, rarely, the liver. In this research study, the investigator are investigating a pre-transplant intervention aimed to prevent GVHD by processing the donor product with the Miltenyi CliniMACS TCR α/β Reagent System. The Reagent System will remove certain cells (called T-Cell Receptor (TCR) α/β positive T-cells) that are thought to cause GVHD from donor product before it is given to the participant. By selectively removing this specific type of T cells from the donor product, the investigators hope to reduce the risk for GVHD without reducing the efficacy of the transplant. This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied. The FDA (the U.S. Food and Drug Administration) has not approved CliniMACS α/β T cell depletion system for use in the US, but this system is approved by the European Medicines Agency (EMA) and used in Europe
