A Phase II Trial of HSCT for the Treatment of Patients With Fanconi Anemia Lacking a Genotypically Identical Donor, Using a Risk-Adjusted Chemotherapy Only Cytoreduction With Busulfan, Cyclophosphamide and Fludarabine
Description
The purpose of this study is to determine whether the use of lower doses of busulfan and the elimination of cyclosporine will further reduce transplant-related side effects for patients with Fanconi Anemia (FA). Patients will undergo a transplant utilizing mis-matched related or matched unrelated donors following a preparative regimen of busulfan, fludarabine, anti-thymocyte globulin and cyclophosphamide.The trial proposed is a three arm phase II treatment protocol designed to investigate the safety and efficacy of risk-adjusted chemotherapy-based cytoreductive regimen plus a CD34+ selected T-cell depleted peripheral blood stem cell (PBSC) stem cell transplant for the treatment of patients with Fanconi anemia and severe hematologic disease. Candidates for this trial will include patients with Fanconi anemia presenting with severe marrow failure (transfusion dependent) or myelodysplastic syndrome, or acute myelogenous leukemia for whom an allogeneic stem cell transplant is indicated.
Trial Eligibility

Pulmonary: asymptomatic or if symptomatic, DLCO \> 50% of predicted * Each patient must be willing to participate as a research subject and must sign an informed consent form. * Female patients and donors must not be pregnant or breastfeeding at the time of signing consent. Women must be willing to undergo a pregnancy test prior to transplant and avoid becoming pregnant while on study. Exclusion Criteria: * Active CNS leukemia * Female patients who are pregnant (positive serum or urine HCG) or breast-feeding. * Active uncontrolled viral, bacterial or fungal infection * Patient seropositive for HIV-I/II; HTLV -I/II
