Keywords

allogeneic stem cell transplantation, t-cell depletion, alpha beta cell depletion

Brief summary

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

DRUGalpha beta depletion

donor cells will be collected and subsequently undergo α/β CD3+/CD19+ cell depletion.
