Study Summary

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.

Primary Outcome

Toxicity will be graded according to the National Cancer Institute's-Common Terminology Criteria for Adverse Events version 5.0. Graft versus host disease (GVHD) specific toxicities will be defined per 1994 Keystone Consensus Criteria. Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study regimen and reversibility or outcome. This will include infectious disease related complica
