Summary

The central hypothesis of this study is that use of a less toxic chemotherapy preparative regimen for allogeneic hematopoietic stem cell transplantation in combination with T cell depletion with alemtuzumab for patients with high risk hematologic malignancies will allow effective control of disease and improved disease free and overall survival compared with historical expectations. Specifically, the objectives are to estimate toxicity, disease free, progression free, event free, and overall survival rates in patients treated with alemtuzumab T cell depleted, reduced intensity preparative regimen followed by allogeneic hematopoietic transplantation; evaluate immune recovery following this reduced intensity allogeneic immunotherapy; develop an in vitro assay to allow patient individualized targeted dosing.

Interventions

DRUG

Non-myeloablative Stem Cell Transplantation

The preparative regimen is 4 days of daily fludarabine at 40 mg/m2/d infused over 30 minutes; melphalan 140 mg/m2/d for 1 day administered over 15 minutes; 4 days of Alemtuzumab at 20 mg/d in 250 ml of normal saline infused over 3 hours. Group B's prep regimen will begin on day -5 or day -4 and busulfan 130mg/m2/d for 2 days over 3 hours. The peripheral blood stem cells (PBSCs) will be infused over 2-4 days. Patient evaluations will occur 2 times per week by physical exam for toxicity through day 45.
