About
This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.
Full description
PRIMARY OBJECTIVES:
I. To determine which dose of Campath (alemtuzumab) allows related and unrelated human leukocyte antigen (HLA) class-II mismatched hematopoietic cell transplantation (HCT) with an incidence of grade III-IV acute graft-versus-host disease (GVHD) less than 40%.
SECONDARY OBJECTIVES:
I. Incidence of graft rejection.
II. Number of days of steroids >= 1mg/kg required before day 100 in each patient.
III. Incidence of non-relapse mortality.
IV. Risk/incidence of infections.
V. Immune reconstitution.
VI. Risk for disease progression and relapse.
OUTLINE: This is a dose-escalation study of alemtuzumab.
NONMYELOABLATIVE CONDITIONING REGIMEN: Patients receive alemtuzumab intravenously (IV) over 6 hours once daily on days -6, -5, and -4 OR days -5 and -4 and fludarabine phosphate IV over 30 minutes on days -4, -3, and -2. Patients also undergo low-dose total-body irradiation (TBI) on day 0.
ALLOGENEIC PERIPHERAL BLOOD STEM CELL TRANSPLANTATION (PBSCT): After completion of TBI, patients undergo allogeneic PBSCT on day 0.
IMMUNOSUPPRESSION: Patients receive cyclosporine orally (PO) or IV every 12 hours on days -3 to 180 followed by a taper until day 365 in the absence of GVHD. Beginning 4-6 hours after completion of allogeneic PBSCT, patients receive mycophenolate mofetil PO every 8 hours on days 0 to 100 followed by a taper until day 156 in the absence of GVHD.
After completion of study treatment, patients are followed up periodically for 12 months, at 18 months, and then annually for 5 years.

Inclusion criteria
-
The patient must be not eligible for conventional transplants and must have disease expected to be stable for at least 100 days without chemotherapy
-
Patients with hematologic malignancies treatable with HCT will be included:
- Aggressive non-Hodgkin lymphomas (NHLs) and other histologies such as diffuse large B-cell NHL: not eligible for autologous HCT, not eligible for conventional myeloablative HCT, or after failed autologous HCT;
- Low grade NHL: with < 6 month duration of complete response (CR) between courses of conventional therapy;
- Mantle cell NHL: may be treated in first CR;
- Chronic lymphocytic leukemia (CLL): must have failed 2 lines of conventional therapy and must be refractory to fludarabine; this includes patients who fail to have a complete or partial response after therapy with a regimen containing fludarabine (or another nucleoside analog] or experience disease relapse within 12 months after completing therapy with a regimen containing fludarabine [or another nucleoside analog);
- Hodgkin's disease (HD): must have received and failed frontline therapy and have failed or were not eligible for autologous transplant;
- Multiple myeloma (MM): must have received prior chemotherapy or failed autografting; following a planned autologous transplant [tandem] is allowed;
- Acute myeloid leukemia (AML): must have < 5% marrow blasts at the time of transplant;
- Acute lymphocytic leukemia (ALL): must have < 5% marrow blasts at the time of transplant;
- Chronic myelogenous leukemia (CML): patients will be accepted beyond first clinical progression (CP1) if they have received previous myelosuppressive chemotherapy or HCT, and have < 5% marrow blasts at time of transplant;
- Myelodysplastic syndrome/myeloproliferative disease (MDS/MPD): must have failed previous myelosuppressive chemotherapy or HCT, and have < 5% marrow blasts at time of transplant;
- Waldenstrom's macroglobulinemia: must have failed 2 courses of therapy
-
Patient refuses 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 Fred Hutchinson Cancer Research Center (FHCRC), and the FHCRC principal investigator
-
Patient with related or unrelated donors for whom:
- There is a likelihood of disease progression while HLA typing and results of a preliminary search and the donor pool suggest that a 10/10 HLA-A, B, C, DRB1 and DQB1 matched unrelated donor will not be found;
- Patient and donor must be matched for at least one DRB1 allele and one DQB1 allele;
- Best available matches are HLA class I HLA-A, -B, -C allele matched donors allowing for any one or two DRB1 and/or DQB1 antigen/allele mismatch;
- There is no indication for an autologous transplantation as a treatment option
-
DONOR: For HLA matching inclusion criteria, see patient inclusion criteria
-
DONOR: Only peripheral blood stem cells (PBSC) will be permitted as a HSC source on this protocol
