What was measured

Estimate toxicity including graft-versus-host disease (GVHD) in participants treated with an alemtuzumab T cell depleted, reduced intensity preparative regimen followed by allogeneic hematopoietic transplantation. Bone marrow aspiration and/or biopsy were performed 3-5 weeks after transplant to assess donor-cell engraftment. Primary Graft Failure was defined as a neutrophil count below 500/μL or the absence of donor-derived hematopoiesis (\<5%donor cells) before relapse, death, or re-transplantation. Secondary Graft Failure was defined as the achievement of primary engraftment and a subsequent decrease in neutrophils to 3 consecutive counts of less than 100/μL or the absence of donor-derived hematopoiesis (\<5% donor cells) before relapse, death, or re-transplantation.

Analysis population: All subjects who received transplant. Cohort A (n=62) had acute or chronic leukemia (ALL or CLL), lymphoma, or myeloma. Cohort B (n=62) had acute or chronic myeloid leukemia (AML or CML), myelodysplastic disorder or myeloproliferative disorder. Analysis by occurrence of Graft versus Host Disease (GvHD) and donor type.

Groups in this outcome

Cohort A & B - Lymphoid & Myeloid Disease

Non-myeloablative Stem Cell Transplant (SCT): Donor will receive Granulocyte colony-stimulating factor (G-CSF) 8 mcg/kg/d subcutaneously twice daily for 4 days, until pheresis is completed or until white blood cells \> 100,000. Recipients will be premedicated with Benadryl 50 mg intravenously (IV) or orally (PO), and acetaminophen 650 mg PO (or hydrocortisone 50-100 mg IV on first day). 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. The prep regimen for myeloid disease 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. Participant evaluations will occur 2 times per week by physical exam for toxicity through day 45.
