Clinical Trial
Study Details
Allogeneic PBSC/marrow will be collected/harvested from the donor after granulocyte colony-stimulating factor (G-CSF) priming. The allogeneic PBSCs will be infused as per current institutional practice.
RATIONALE: Although used primarily to treat malignant disorders of the blood, allogeneic stem cell transplantation can also cure a variety of non-cancerous, inherited or acquired disorders of the blood. Unfortunately, the conventional approach to allogeneic stem cell transplantation is a risky procedure. For some non-cancerous conditions, the risks of this procedure outweigh the potential benefits. This protocol is designed to test a new approach to allogeneic stem cell transplantation. It is hoped that this approach will be better suited for patients with non-cancerous blood and bone marrow disorders.
Study Overview
OBJECTIVES:
Primary Objective(s):
1. Evaluate the feasibility in terms of mortality, occurrence of acute graft versus host disease, and grades 3-4/4 toxicity of in vivo and in vitro Campath coupled with concomitantly administered nonmyeloablative fludarabine, cyclophosphamide and total body irradiation (TBI) followed by Human Leukocyte Antigen (HLA) 5-6/6 matched family member allo peripheral blood stem cell transplant (PBSCT).
2. Evaluate the engraftment rate of HLA 5-6/6 matched family member patients who receive in vivo Campath followed by concomitantly administered fludarabine, cyclophosphamide and total body irradiation (TBI) as a conditioning regimen with Campath-treated peripheral blood stem cells (in vitro and in vivo exposure).
Secondary Objective(s):
1. Evaluate the response rate and survival of patients who receive a non-myeloablative conditioning regimen of in vivo Campath followed by concomitantly administered fludarabine, cyclophosphamide and total body irradiation (TBI) with Campath-treated peripheral blood stem cells.
2. Evaluate the recovery of immune function post engraftment with this regimen.
