Official title
Allogeneic Stem Cell Transplantation for Malignant and Non-malignant Hematologic Diseases Utilizing Alpha/Beta T Cell and CD19+ B Cell Depletion - NYMC 588
Overview
Children, adolescents, and young adults with malignant and non-malignant conditionsundergoing an allogeneic stem cell transplantation (AlloSCT) will have the stem cells selected utilizing α/β CD3+/CD19+ cell depletion. All other treatment is standard of care.
Detailed description
Patients wiith selected malignant or non-malignant conditions meeting eligibility criteria will be enrolled on this study. Patients will receive one of either full intensity, reduced intensity, or reduced toxicity conditioning appropriate based on disease, disease status, organ function and performance status and will undergo α/β T-cell and CD 19+ B cell depleted alloSCT.
Patients will be following for engraftment, chimerism, immune reconstitution, GVHD and QOL.
Interventions
- Drug alpha beta depletion
donor cells will be collected and subsequently undergo α/β CD3+/CD19+ cell depletion.
Primary outcome measures
- incidence of adverse events related to administration of α/β CD3+/CD19+ cell depleted stem cells [Time frame: 1 year]
Secondary outcome measures (2)
- incidence of hematpoitic engraftment following Allogeneic stem cell transplantation (AlloSCT) utilizing α/β CD3+/CD19+ cell depletion [Time frame: 1 year]
- incidence of GVHD following Allogeneic stem cell transplantation (AlloSCT) utilizing α/β CD3+/CD19+ cell depletion [Time frame: 1 year]
