Fludarabine Phosphate and Total Body Irradiation Followed by a Donor Peripheral Stem Cell Transplant in Treating Patients With Myelodysplastic Syndromes or Myeloproliferative Disorders

Completed · Phase 2

Conditions studied: Atypical Chronic Myeloid Leukemia, BCR-ABL1 Negative, Chronic Myelomonocytic Leukemia, de Novo Myelodysplastic Syndrome, Essential Thrombocythemia, Myeloproliferative Neoplasm, Paroxysmal Nocturnal Hemoglobinuria, Polycythemia Vera, Polycythemia Vera, Post-Polycythemic Myelofibrosis Phase, Primary Myelofibrosis, Refractory Anemia, Refractory Anemia With Excess Blasts, Refractory Anemia With Ring Sideroblasts, Refractory Cytopenia With Multilineage Dysplasia, Refractory Cytopenia With Multilineage Dysplasia and Ring Sideroblasts

In brief

This phase II trial studies the side effects and best dose of total-body irradiation when given together with fludarabine phosphate followed by a donor peripheral stem cell transplant in treating patients with myelodysplastic syndromes (MDS) or myeloproliferative disorders (MPD). 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. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's 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.

Paroxysmal nocturnal hemoglobinuria (PNH): Patients with the non-aplastic form of PNH (cellular bone marrow) who have had a history of life-threatening complications of their disease including thrombotic events, severe hemolysis or Budd Chiari syndrome are eligible; other patients may be considered following approval at PCC and approval by the Principal investigator
Matched Related Donor: Related to the patient and is genotypically or phenotypically HLA-identical
Matched Related Donor: Donor age < 75 yrs unless cleared by institutional PI

You may not qualify if…

Matched Related Donor: Pregnant or lactating females
Matched Related Donor: Prior malignancy within the preceding five yrs, with the exception of non-melanoma skin cancers

Unrelated Donor: A positive anti-donor cytotoxic crossmatch is an absolute donor exclusion; 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
Unrelated Donor: Marrow donors
