About
This phase II trial studies the side effects and the best dose of alemtuzumab when given together with fludarabine phosphate and low-dose total body irradiation (TBI) and how well it works before donor stem cell transplant in treating patients with hematological malignancies. Giving chemotherapy and low-dose TBI before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. Also, monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after transplant may stop this from happening.
Full description
PRIMARY OBJECTIVES:
I. To determine whether stable allogeneic engraftment from related and unrelated human leukocyte antigen (HLA)-mismatched stem cell donors can be safely established using a non-myeloablative conditioning regimen plus escalating doses of the anti-CD52 monoclonal antibody (mAb) Campath (alemtuzumab) in patients with hematologic malignancies.
SECONDARY OBJECTIVES:
I. Evaluate the risk of occurrence of acute and chronic graft-vs-host disease (GVHD).
II. Evaluate the risk/incidence of infections.
III. Determine whether engraftment can be maintained with a single dose fludarabine, donor lymphocyte infusion (DLI) and continued MMF/CSP.
IV. Evaluate the risk for disease progression and relapse.
OUTLINE: This is a dose-escalation study of alemtuzumab.
CONDITIONING REGIMEN: Patients receive alemtuzumab intravenously (IV) over 2 hours on days -8 to -5 and fludarabine phosphate IV on days -4 to -2. Patients also undergo low-dose TBI on day 0.
HEMATOPOIETIC STEM CELL TRANSPLANTATION (HSCT): Patients undergo allogeneic peripheral blood stem cell transplantation on day 0.
IMMUNOSUPPRESSION: Patients receive CSP IV or orally (PO) twice daily (BID) on days -3 to 180 with taper to day 365 and MMF PO thrice daily (TID) on days 0-100 with taper to day 156.
After completion of study treatment, patients are followed up periodically.

Hodgkin disease (HD) - Must have received and failed frontline therapy; patients must have had a prior autologous transplant or were not eligible for autologous transplant; planned tandem transplants are allowed for patients at high risk of relapse
Multiple myeloma (MM) - Must have received prior chemotherapy and a prior autologous transplant, unless autologous transplant was not possible; planned tandem transplants are allowed for patients at high risk of relapse
Acute myeloid leukemia (AML) - Must have < 5% marrow blasts at the time of transplant
Acute lymphocytic leukemia (ALL) - Must have < 5% blasts at the time of transplant

Myelodysplastic (MDS)/Myeloproliferative disorders - Must have failed previous myelosuppressive chemotherapy or HSCT, and have < 5% marrow blasts at time of transplant
Waldenstrom's Macroglobulinemia - Must have failed 2 courses of therapy
Patients < 12 years old must be approved by the Fred Hutchinson Cancer Research Center (FHCRC) principal investigator (PI)
Patients who refuse to be treated on a conventional transplant protocol; for this inclusion, criteria transplants must be approved by both the participating institution´s patient review committee such as the Patient Care Conference (PCC) at the FHCRC and the FHCRC principal investigator
Patients with related or unrelated donors for whom
DONOR: Related or unrelated donors who are matched for HLA-DRB1 and DQB1 alleles (must be defined by high resolution typing), and who are mismatched for:
Exclusion criteria
Patients who are homozygous at the mismatched major histocompatibility complex (MHC) class I locus
A positive cross-match exists between the donor and recipient
Patients with rapidly progressive intermediate or high grade NHL
Presence of circulating leukemic blasts (in the peripheral blood) detected by standard pathology for patients with AML, ALL or CML
Life expectancy severely limited by diseases other than malignancy
Central nervous system (CNS) involvement with disease refractory to intrathecal chemotherapy
Fertile men or women unwilling to use contraceptives during and for up to 12 months post treatment
Female patients who are pregnant or breast-feeding
Human immunodeficiency virus (HIV) positive patients
Patients with active non-hematologic malignancies (except non-melanoma skin cancers)
Patients with a history of non-hematologic malignancies (except non-melanoma skin cancers) currently in a complete remission, who are less than 5 years from the time of complete remission, and have a > 20% risk of disease recurrence
Fungal infections with radiological progression after receipt of amphotericin B or active triazole for greater than 1 month
Patients with active bacterial or fungal infections unresponsive to medical therapy
Patients with the following organ dysfunction symptomatic coronary artery disease or ejection fraction < 35% or other cardiac failure requiring therapy; ejection fraction is required if the patient is > 50 years of age, or history of cardiac disease or anthracycline exposure
DONOR: Bone marrow (BM) donors
DONOR: Donors who are HIV-positive and/or, medical conditions that would result in increased risk for granulocyte colony-stimulating factor (G-CSF) mobilization and harvest of peripheral blood stem cell (PBSC)
DONOR: Donors < 12 years of age
