CD34+ Stem Cell Selection for Patients Receiving a Matched or Partially Matched Family or Unrelated Adult Donor Allogeneic Stem Cell Transplant for Malignant Disease

What's the purpose of this trial?

The purpose of this study is to learn more about the effects of (classification determinant) CD34+ stem cell selection on graft versus host disease (GVHD) in children, adolescents, and young adults. CD34+ stem cells are the cells that make all the types of blood cells in the body. GVHD is a condition that results from a reaction of transplanted donor T-lymphocytes (a kind of white blood cell) against the recipient's body and organs. Study subjects will be offered treatment involving the use of the CliniMACS® Reagent System (Miltenyi Biotec), a CD34+ selection device to remove T-cells from a peripheral blood stem cell transplant in order to decrease the risk of acute and chronic GVHD. This study involves subjects who are diagnosed with a malignant disease, that has either failed standard therapy or is unlikely to be cured with standard non-transplant therapy, who will receive a peripheral blood stem cell transplant. A malignant disease includes the following: Chronic Myeloid Leukemia (CML) in chronic phase, accelerated phase or blast crisis; Acute Myelogenous Leukemia (AML); Myelodysplastic Syndrome (MDS); Juvenile Myelomonocytic Leukemia (JMML); Acute Lymphoblastic Leukemia (ALL); or Lymphoma (Hodgkin's and Non-Hodgkin's).

This trial is currently open and accepting patients.
