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.

Experimental: alpha beta cell depletion
Matched allogeneic donor stem cells will be processed utilizing α/β CD3+/CD19+ cell depletion with the Prodigy system. Standard pre-conditioning and post-transplant motioning will be given.
|
Drug: alpha beta depletion
donor cells will be collected and subsequently undergo α/β CD3+/CD19+ cell depletion.
Other Name: α/β CD3+/CD19+ cell depletion |
- incidence of adverse events related to administration of α/β CD3+/CD19+ cell depleted stem cells [ Time Frame: 1 year ]patients will be monitored for any adverse events related to administration of α/β CD3+/CD19+ cell depleted stem cells
- incidence of hematpoitic engraftment following Allogeneic stem cell transplantation (AlloSCT) utilizing α/β CD3+/CD19+ cell depletion [ Time Frame: 1 year ]patients will have routine chimerism performed to monitoring engraftment of donor cells
- incidence of GVHD following Allogeneic stem cell transplantation (AlloSCT) utilizing α/β CD3+/CD19+ cell depletion [ Time Frame: 1 year ]patients will be monitored post transplant for signs of acute and chronic GVHD
