About this study

This phase I trial evaluates the safety and feasibility of using a reduced-intensity regimen of cyclophosphamide, pentostatin, and anti-thymocyte globulin prior to a CD4+ T-cell depleted haploidentical hematopoietic cell transplant (haploHCT) for the treatment of patients with severe aplastic anemia that does not respond to treatment (refractory) or that has come back (recurrent). Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid. It may also lower the body's immune response. Pentostatin blocks a protein needed for cell growth. Anti-thymocyte globulin is an immunosuppressive drug can destroy immune cells known as T-cells. HaploHCT transfers blood-forming stem cells from a healthy partially-matched donor to a patient. Administering a regimen of cyclophosphamide, pentostatin, and anti-thymocyte globulin before haploHCT may help make room for the new, healthy cells and may reduce the risk of graft versus host disease.
