Specialized Stem Cell Transplant Product (Hematopoietic Progenitor Blood Cell Graft Cells) for the Treatment of Children, Adolescent and Young Adult Patients with Hematologic Cancers
This phase II trial tests whether a new type of specialized stem cell transplant product (hematopoietic progenitor blood cell [HPC-A] graft cells) is safe and effective in treating patients with hematologic cancers. This study also evaluates whether the use of HPC-A graft cells results in reduced rates of graft-versus-host disease (GVHD) and infection and improved patient outcomes. A common risk with stem cell transplants is GVHD, which occurs when donor cells (the graft) see the patient’s normal cells (the host) as foreign and attack them. Removing certain types of white blood cells from the donor product before the transplant may stop or reduce the risk of this happening. The HPC-A graft cells used in this study are hematopoietic progenitor cells collected from healthy donors and altered to remove the T-cell receptor (TCR) alpha and beta as well as CD19-positive cells. These TCR alpha/beta/CD19-depleted allogeneic hematopoietic progenitor cells may be safe and effective in treating patients with hematologic malignancies while reducing the risk of GVHD.

SECONDARY OBJECTIVES:
I. To evaluate event free survival (EFS) and overall survival at 1 year.
II. To determine the probability of hematopoietic engraftment as measured by the presence of donor chimerism > 95% by day 100 after alloSCT utilizing alpha/beta CD3+/CD19+ cell depletion.
III. To determine the incidence of cytomegalovirus (CMV), Epstein Barr virus (EBV), and adenovirus viremia and post-transplant lymphoproliferative disorder (PTLD).
