About
This randomized phase II trial includes a blood stem cell transplant from an unrelated donor to treat blood cancer. The treatment also includes chemotherapy drugs, but in lower doses than conventional (standard) stem cell transplants. The researchers will compare two different drug combinations used to reduce the risk of a common but serious complication called "graft versus host disease" (GVHD) following the transplant. Two drugs, cyclosporine (CSP) and sirolimus (SIR), will be combined with either mycophenolate mofetil (MMF) or post-transplant cyclophosphamide (PTCy). This part of the transplant procedure is the main research focus of the study.
Full description
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients undergo allogeneic hematopoietic stem cell transplant (HCT) at day 0. Patients with an HLA-matched unrelated donor receive mycophenolate mofetil orally (PO) on days 0 to 40, cyclosporine PO every 12 hours twice daily (BID) on days -3 to 96 then tapered to day 150, and sirolimus PO once daily (QD) on days -3 to day 150 then tapered to day 180. Patients with an HLA-mismatched donor receive mycophenolate mofetil PO on days 0-100 then tapered to day 150, cyclosporine PO BID on days -3 to 150 then tapered to day 180, and sirolimus PO QD on days -3 to 180 then tapered to day 365.
ARM II: Patients undergo HCT at day 0. Patients with an HLA-matched unrelated donor receive cyclosporine PO BID on days 5-96 then tapered to day 150, sirolimus PO QD on days 5-150 then tapered to day 180, and cyclophosphamide intravenously (IV) on days 3 and 4. Patients with an HLA-mismatched donor receive cyclosporine PO BID on days 5-150 then tapered to day 180, sirolimus PO QD on days 5-180 then tapered to day 365, and cyclophosphamide IV on days 3 and 4.
After completion of study treatment, patients are followed up at 6 months and every year thereafter.

HLA-MATCHED UNRELATED DONOR: FHCRC matching allowed will be grades 1.0 to 2.1; unrelated donors who are prospectively:
- Matched for HLA-A, B, C, DRB1 and DQB1 by high resolution typing;
- Only a single allele disparity will be allowed for HLA-A, B, or C as defined by high resolution typing
-
HLA-MATCHED UNRELATED 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
-
HLA-MATCHED UNRELATED 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
-
HLA-MATCHED UNRELATED DONOR: Only granulocyte colony-stimulating factor (G-CSF) mobilized PBSC will be permitted as a HSC source on this protocol
-
HLA-MISMATCHED UNRELATED DONOR: Unrelated volunteer donors who are mismatched with the recipient within one of the following limitations:
- Mismatch for one HLA class I antigen with or without an additional mismatch for one HLA-class I allele, but matched for HLA-DRB1 and HLA-DQ, OR
- Mismatched for two HLA class I alleles, but matched for HLA-DRB1 and HLA-DQ
- HLA class I HLA-A, -B, -C allele matched donors allowing for any one or two DRB1 and/or DQB1 antigen/allele mismatch
-
HLA-MISMATCHED UNRELATED DONOR: HLA-matching must be based on results of high resolution typing at HLA-A, -B, -C, - DRB1, and -DQ
-
HLA-MISMATCHED UNRELATED DONOR: If the patient is homozygous at the mismatch HLA class I locus or II locus, the donor must be heterozygous at that locus and one allele must match the patient (i.e., patient is homozygous A*01:01 and donor is heterozygous A*01:01, A*02:01); this mismatch will be considered a one-antigen mismatch for rejection only
