Purpose
The purpose of this trial is to determine if patients with hematologic diseases who have a HLA 6/6 matched related donor and are not eligible for a standard myeloablative stem cell transplant will have less severe graft versus host disease (GVHD), transplant related mortality, and less graft failure when treated with a non-myeloablative T-cell depleted stem cell transplant.

- To evaluate the risks of severe (grade III/IV) GVHD or transplant related mortality at < 100 days following HLA-matched non-myeloablative stem cell transplantation (or following "prophylactic" DLI given for chimerism conversion). [ Time Frame: 100 days ] [ Designated as safety issue: Yes ]
- To evaluate the incidence of acute and chronic GVHD. [ Time Frame: indefinite ] [ Designated as safety issue: Yes ]
- To evaluate the incidence of graft loss. [ Time Frame: 100 days ] [ Designated as safety issue: Yes ]
- To evaluate progression free and overall survival. [ Time Frame: indefinite ] [ Designated as safety issue: Yes ]

Detailed Description:
Our prior experience in the lab and in clinical trials with non-myeloablative HLA-matched and mismatched transplant strategies have been remarkable for a low transplant related mortality rate, but a still formidable risk of GVHD and graft rejection. In this trial, we have incorporated a combination ex-vivo T-cell depletion strategy to prevent GVHD with vigorous in vivo depletion of host (and to a lesser extent donor) T-cells to prevent graft rejection.
Patients will receive non-myeloablative conditioning with cyclophosphamide, thymoglobulin, fludarabine, and thymic irradiation, followed by a T-cell depleted PBSC infusion. Cyclosporine will be given for GVHD prophylaxis, and tapered beginning on day 35. Data from our mouse model and previous clinical trials have demonstrated that this approach can induce mixed chimerism without GVHD, with the potential for conversion of mixed chimerism to full donor hematopoiesis following donor leukocyte infusions.
