This is a single arm pilot study using TCR alpha/beta+ T cell-depleted peripheral blood stem cells (PBSC) from closely matched unrelated donors or partially matched/haploidentical related donors for hematopoietic stem cell transplant (HSCT) in patients with acquired and inherited bone marrow failure (BMF) syndromes. Previously established, disease-specific transplant preparative regimens will be administered based on the specific underlying BMF condition. Mobilized PBSC will be processed using the CliniMACS system for TCR alpha/beta+ T cell depletion plus cluster of differentiation 19+ (CD19+) B cell depletion. The study will determine efficacy of this strategy in terms of engraftment, rates of acute and chronic Graft versus Host Disease (GvHD), and one year overall and event-free survival.
