Myeloablative Allogeneic Stem Cell Transplantation Using a Naive T-Cell Depleted Peripheral Blood Stem Cell Graft

"The Isolex device from Baxter will be used to perform the cell selection procedure. After the CD34 selected stem cell graft has been collected, the CD34- flow-throughfraction will be depleted of CD45RA+ naive T-cells. To accomplish this, a second immunomagnetic bead selection process will be performed on the Isolex device, making use of a GMP-grade murine anti-human CE45RA antibody. This depleted fraction will comprise the donor lymphocyte inoculum given to the transplant recipient along with the stem cell component on day 0 of transplant."

These patients will be transplanted with unmanipulated peripheral blood stem cells.
