Experimental: Haploidentical Allogeneic Transplantation
Patients undergoing hematopoietic stem cell transplant from a partially matched related donor
Radiation: Total Body Irradiation (TBI)
TBI twice daily days 6-9 prior to transplant (HSCT)
Other Names:Biological: Donor Lymphocyte Infusion (DLI)
DLI given 6 days prior to transplant (HSCT).
Other Names:Drug: Cyclophosphamide (CY)
Cyclophosphamide given once daily at 60 mg/kg on days 2 and 3 prior to transplant (HSCT).
Other Names:Drug: Tacrolimus
Tacrolimus given one day prior to transplant (HSCT).
Other Names:Drug: Mycophenolate Mofetil (MMF)
MMF given one day prior to transplant (HSCT).
Other Names:Biological: Hematopoietic Stem Cell Transplant (HSCT)
CD34+ selected Hematopoietic Stem Cell Transplant (HSCT) is performed. This is the day of transplantation.
- Overall Survival of Participants [ Time Frame: 6 months ]To determine overall survival at 6 months post-transplant.
- Optimal Dose of CD3+ Donor Lymphocytes (T-cells) for Consistent Engraftment Without GVHD [ Time Frame: 6 months ]
To determine the optimal dose of CD3+ donor lymphocytes required for consistent engraftment without the development of grade III/IV GVHD.
Measured as CD3+ donor lymphocytes given as n x 10^8/kg.
"n" was found to be 2 and was found to be the optimal dose and was the only dose given.
- Engraftment Rates [ Time Frame: 6 months ]To assess hematopoietic engraftment rates.
- Lymphoid Recovery [ Time Frame: 6 months ]To assess the pace of lymphoid recovery in this patient population.
- Incidence of Grades III-IV GVHD [ Time Frame: 6 months ]
To determine the incidence and severity of GVHD in these patients using a combination of cyclophosphamide, tacrolimus and mycophenolate mofetil (MMF) as GVHD prophylaxis.'
Severity was graded using CTCAE 3.0 (1=mild, 2=moderate, 3=severe, 4=life threatening/disabling, 5=death)
