Study Summary
This study is a prospective, single center phase II clinical trial in which patients with Severe Aplastic Anemia (SAA) ) will receive a haploidentical transplantation. The purpose of this study is to learn more about newer methods of transplanting blood forming cells donated by a family member that is not fully matched to the patient. This includes studying the effects of the chemotherapy, radiation, the transplanted cell product and additional white blood cell (lymphocyte) infusions on the patient's body, disease and overall survival. The primary objective is to assess the rate of engraftment at 30 days and overall survival (OS) and event free survival (EFS) at 1 year post-hematopoietic cell transplantation (HCT). Primary Objectives * To estimate the rate of engraftment at 30 days after TCR αβ+ T-cell-depleted graft infusion in patients receiving a single dose of post graft infusion cyclophosphamide. * To estimate the overall survival and event free survival at 1-year post transplantation. Secondary Objectives * To calculate the incidence of acute and chronic GVHD after HCT. * To calculate the rate of secondary graft rejection at 1-year post transplantation * To calculate the cumulative incidence of viral reactivation (CMV, EBV and adenovirus). * To describe the immune reconstitution after TCR αβ+ T-cell-depleted graft infusion at 1 month, 3 months, 6 months, 9 months, and 1 year. Exploratory Objectives * To longitudinally assess the phenotype and epigenetic profile of T-cells in SAA patients receiving HCT for SAA. * To assess the phenotype and epigenetic profile of T-cells in DLI administered to SAA patients post HCT. * To longitudinally assess CD8 T cell differentiation status in SAA patients using an epigenetic atlas of human CD8 T cell differentiation. * To examine the effector functions and proliferative capacity of CD8 T cells isolated from SAA patients before and after DLI. * Quantify donor derived Treg cells at different time points in patients receiv
Primary Outcome
Rate of patients engrafting at day 30 after TCR αβ+ T-cell-depleted graft infusion in patients receiving a single dose of post graft infusion cyclophosphamide.
