I. To demonstrate efficacy of this approach over the historical 2 step reduced intensity conditioning (RIC) approaches in the "vulnerable" population defined as: patients with hematopoietic cell transplant (HCT)-co-morbidity index (CI)/age scores >= 2, but no more than a score of 5 as based on the Sorror et al. data.
I. To compare the non-relapse mortality (NRM) and relapse related mortality (RRM) rates at 1 year for patients treated on this study to the that of patients undergoing haploidentical RIC hematopoietic stem cell transplantation (HSCT) as reported in the literature and as observed in the 2 step RIC trials.
II. To determine the incidence and severity of graft-versus-host disease (GVHD) in patients undergoing treated on the Thomas Jefferson University (TJU) RIC 2 step approach.
III. To evaluate engraftment rates and lymphoid reconstitution in patients treated on the TJU RIC 2 step approach.
RIC: Patients receive fludarabine phosphate intravenously (IV) over 60 minutes on days -10 to -8 and cyclophosphamide IV over 2 hours on days -3 and -2. Patients also undergo total body irradiation (TBI) followed by a donor lymphocyte infusion (DLI) on day -6.
TRANSPLANT: Patients undergo cluster of differentiation (CD)34+ peripheral blood stem cell transplant on day 0.
GVHD PROPHYLAXIS: Patients receive tacrolimus orally (PO) beginning day -1 with a taper initiated on day 42 and mycophenolate mofetil IV twice daily (BID) on days -1 to 28 in the absence of GVHD.
After completion of study treatment, patients are followed up for 1 year.

|Official Title:||A Two Step Approach to Non-Myeloablative Allogeneic Hematopoietic Stem Cell Transplantation for Patients With Hematologic Malignancies|
|Actual Study Start Date :||November 13, 2015|
|Estimated Primary Completion Date :||January 2022|
|Estimated Study Completion Date :||April 2022|
Experimental: RIC HSCT, GVHD prophylaxis
RIC: Patients receive fludarabine phosphate IV on days -10 to -8 and cyclophosphamide IV on days -3 and -2. Patients also undergo TBI followed by a DLI on day -7.
TRANSPLANT: Patients undergo CD34+ peripheral blood stem cell transplant on day 0.
GVHD PROPHYLAXIS: Patients receive tacrolimus PO beginning day -1 with a taper initiated on day 42 and mycophenolate mofetil IV BID on days -1 to 28 in the absence of GVHD.
Radiation: Total-Body Irradiation
Biological: T Cell-Depleted Donor Lymphocyte Infusion
Procedure: Peripheral Blood Stem Cell Transplantation
Undergo PBSC transplant
Procedure: Allogeneic Hematopoietic Stem Cell Transplantation
Undergo PBSC transplant
Drug: Mycophenolate mofetil
- Overall Survival (OS) [ Time Frame: At 1 year post HSCT ]OS will be estimated using Kaplan-Meier curves. The 1-year OS rate and corresponding 95% confidence interval will be estimated from the Kaplan-Meier curve for the OS.
- Relapse Related Mortality (RRM) [ Time Frame: At 1 year post HSCT ]Will be reported descriptively. RRM may also be estimated using Kaplan Meier curves and/or cumulative incidence analyses.
- Non-Relapse Mortality (NRM) [ Time Frame: At 1 year post HSCT ]Will be reported descriptively. NRM may also be estimated using Kaplan Meier curves and/or cumulative incidence analyses.
- Incidence and severity of GVHD [ Time Frame: Up to 1 year post HSCT ]Will be reported descriptively
- Engraftment rates [ Time Frame: Up to 1 year post HSCT ]Will be reported descriptively
- Lymphoid reconstitution [ Time Frame: Up to 1 year post HSCT ]Lymphoid reconstitution will be evaluated monthly to every other month during the first year post HSCT and will be reported descriptively.
