About
This randomized phase II trial studies how well giving tacrolimus and mycophenolate mofetil (MMF) with or without sirolimus works in preventing acute graft-versus-host disease (GVHD) in patients undergoing donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body-irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system 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 MMF and tacrolimus with or without sirolimus after transplant may stop this from happening.
Full description
PRIMARY OBJECTIVES:
I. To determine which of 3 GVHD prophylaxis regimens results in reduction of acute grades II-IV GVHD to =< 40%.
SECONDARY OBJECTIVES:
I. Reduce the incidence of non-relapse mortality from infections and GVHD before day 200 to =< 15%.
II. Reduce the utilization of high-dose corticosteroids compared to protocols 1463, 1641, and 1668.
III. Compare survival and progression-free survival to that achieved under protocols 1463, 1641, and 1668.
OUTLINE:
CONDITIONING: All patients receive fludarabine phosphate intravenously (IV) over 30 minutes on days -4 to -2 and undergo total-body irradiation on day 0.
TRANSPLANTATION: All patients undergo allogeneic peripheral blood stem cell transplantation on day 0.
IMMUNOSUPPRESSION: Patients are randomized to 1 of 3 treatment arms.
ARM I: Patients receive tacrolimus IV or orally (PO) every 12 hours on days -3 to 180 with taper beginning on day 100 in the absence of GVHD. Patients also receive MMF PO every 8 hours on days 0-29 and then every 12 hours on days 30-96 with taper beginning on day 40 in the absence of GVHD.
ARM II: Patients receive tacrolimus IV or PO every 12 hours on days -3 to 150 with taper beginning on day 100 in the absence of GVHD. Patients also receive MMF PO every 8 hours on days 0-29 and then every 12 hours on days 30-180 with taper beginning on day 150 in the absence of GVHD.
ARM III: Patients receive tacrolimus and MMF as in arm II. Patients also receive sirolimus PO once daily on days -3 to 80.
After completion of study treatment, patients are followed up at 6 months and then every year thereafter.

Inclusion criteria
Ages > 50 years with hematologic malignancies treatable by unrelated hematopoietic cell transplant (HCT)
Ages =< 50 years of age with hematologic diseases treatable by allogeneic HCT who through pre-existing medical conditions or prior therapy are considered to be at high risk for regimen related toxicity associated with a conventional transplant (> 40% risk of transplant related mortality [TRM]) (This criterion can include patients with a HCT-comorbidity index (CI) score of >= 1; transplants should be approved for these inclusion criteria by both the participating institutions' patient review committees such as the Patient Care Conference (PCC) at the Fred Hutchinson Cancer Research Center (FHCRC) and by the principal investigators at the collaborating centers)
Patients =< 50 years of age who have received previous high-dose transplantation do not require patient review committee approvals (All children < 12 years must be discussed with the FHCRC principal investigator (PI) [Brenda Sandmaier, MD 206 6674961] prior to registration)
Ages =< 50 years of age with chronic lymphocytic leukemia (CLL); these patients do not require patient review committee approvals
Ages =< 50 years of age with hematologic diseases treatable by allogeneic HCT who refuse a conventional HCT (Transplants must be approved for these inclusion criteria by both the participating institutions' patient review committee such as PCC at the FHCRC and by the principal investigators at the collaborating centers)
The following diseases will be permitted although other diagnoses can be considered if approved by PCC or the participating institutions' patient review committees and the principal investigators:
Aggressive non-Hodgkin lymphomas (NHL) and other histologies such as Diffuse large B cell NHL not eligible for autologous hematopoietic stem cell transplant (HSCT), not eligible for conventional myeloablative HSCT, or after failed autologous HSCT
Mantle Cell NHL may be treated in first complete response (CR) (Diagnostic lumbar puncture [LP] required pretransplant)
Low grade NHL with < 6 month duration of CR between courses of conventional therapy
CLL must have either
Hodgkin Lymphoma must have received and failed frontline therapy
Multiple Myeloma must have received prior chemotherapy; consolidation of chemotherapy by autografting prior to nonmyeloablative HCT is permitted
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 Myeloid Leukemia (CML) patients will be accepted if they are beyond chronic phase (CP)1 and if they have received previous myelosuppressive chemotherapy or HCT and have < 5% marrow blasts at time of transplant
Myelodysplasia (MDS)/Myeloproliferative Syndrome (MPS) patients must have received previous myelosuppressive chemotherapy or HCT and have < 5% marrow blasts at time of transplant
Waldenstrom's Macroglobulinemia must have failed 2 courses of therapy
DONOR: FHCRC matching allowed will be Grades 1.0 to 2.1: unrelated donors who are prospectively:
DONOR: Donors are excluded when preexisting immunoreactivity is identified that would jeopardize donor hematopoietic cell engraftment; this determination is based on the standard practice of the individual institution; the recommended procedure for patients with 10 of 10 HLA allele level (phenotypic) match is to obtain a panel reactive antibody (PRA) screens to class I and class II antigens for all patients before HCT; if the PRA shows > 10% activity, then flow cytometric or B and T cell cytotoxic cross matches should be obtained; the donor should be excluded if any of the cytotoxic cross match assays are positive; for those patients with an HLA Class I allele mismatch, flow cytometric or B and T cell cytotoxic cross matches should be obtained regardless of the PRA results; a positive anti-donor cytotoxic crossmatch is an absolute donor exclusion
DONOR: Patient and donor pairs homozygous at a mismatched allele in the graft rejection vector are considered a two-allele mismatch, i.e., the patient is A*0101 and the donor is A*0102, and this type of mismatch is not allowed
DONOR: Only filgrastim (G-CSF) mobilized peripheral blood mononuclear cell (PBMC) only will be permitted as a HSC source on this protocol
