Summary

Results to date of umbilical cord blood transplantation in adult and fully mature adolescent patients are inferior to what is seen in children, due to a lower stem cell dosage in adults and a more toxic conditioning regimen. This phase 1 protocol will use a potentially less toxic bone marrow conditioning regimen, followed by infusion of a combined umbilical cord blood graft that will provide the patient with a higher stem cell dose than can be given with a single umbilical cord blood infusion. The subjects will be conditioned with a total body irradiation (TBI) 13.5 Gy and fludarabine. Following conditioning, up to two unrelated, partially matched umbilical cord blood grafts will be infused that will provide a minimum nucleated cell dose of 3 x 10e7/kg . The primary objective of this study is to measure the frequency of treatment-related toxicity and engraftment.

PROCEDURE

Total Body Irradiation with Fludarabine in UCB Transplants

Administration of the preparative regimen, infusion of the stem cell graft, inpatient care during the immediate post-transplant period and outpatient follow-up for the first 3 months after transplant and at 6, 12, 24 and 36 months. Patients will have human leukocyte antigen (HLA) serologic typing and DNA typing. Bags of UCB are thawed, and diluted by 1:1 volume using a 5% albumin/dextran solution. The thawed and diluted umbilical cord blood unit (UCBU) is next weighed and centrifuged. Specimens are obtained for cell count and viability, culture, clonogenic assays, and phenotype. The UCB is infused at a rate of 1-3 ml/min. Furosemide (0.5-1.0 mg/kg/dose) may be given if volume overload or decreased urine output occurs. Each UCB infusion shall be tested for sterility, CFU content, number of CD34+ cells, cell count and viability.
