RATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the stem 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 make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening.
PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.
Further Study Information
- Determine the 1-year survival of patients undergoing unrelated umbilical cord blood transplantation (UCBT) for hematologic malignancies treated with myeloablative preparative regimen comprising fludarabine, cyclophosphamide, and fractionated total-body irradiation.
- Determine the incidence of transplant-related mortality at 6 months after UCBT.
- Evaluate the pattern of chimerism after double UCBT.
- Determine the incidence of neutrophil engraftment at day 42 after UCBT.
- Determine the incidence of platelet engraftment at 6 months after UCBT.
- Determine the incidence of grade II-IV and grade III-IV acute graft-versus-host disease (GVHD) at day 100 after UCBT.
- Determine the incidence of chronic GVHD at 1 year after UCBT.
- Determine the disease-free survival at 1 and 2 years after UCBT.
- Determine the incidence of relapse at 1 year after UCBT.
OUTLINE: This is a nonrandomized, open-label, multicenter study.
- Preparative Regimen: Patients receive fludarabine IV over 1 hour on days -8 to -6 and cyclophosphamide IV on days -7 and -6. Patients also undergo total-body irradiation twice daily on days -4 to -1.
- Umbilical Cord Blood Transplantation (UCBT): Patients undergo 1 or 2 units of UCBT on day 0. Patients receive filgrastim (G-CSF) IV once daily beginning on day 1 and continuing until blood counts recover.
- Graft-versus-host disease (GVHD) prophylaxis: Patients receive cyclosporine IV over 2 hours 2 or 3 times daily beginning on day -3 and continuing until day 100 followed by a taper until day 180. Patients also receive mycophenolate mofetil IV or orally 2 or 3 times a day beginning on day -3 and continuing until day 30 or 7 days after engraftment in the absence of acute GVHD.
After completion of study treatment, patients are followed periodically for at least 5 years.
PROJECTED ACCRUAL: A total of 150 patients will be accrued for this study.
- Graft Criteria
- The unrelated cord blood donor(s) must be 4-6/6 HLA-A, B, DRB1 matched with the recipient (HLA matching using molecular techniques: A and B to antigen level resolution and DR to allele level resolution).
- No existing HLA-identical related donor is available.
- Suitable UCB units available according to Umbilical Cord Blood Graft (UCB) selection algorithm. The UCB graft may consist of one or two UCB units.
- Age and Disease Criteria
- Patients aged ≤ 55 years must have a hematological malignancy as described below:
- Acute myeloid leukemia (AML): high risk CR1 (as evidenced by preceding myelodysplastic syndrome [MDS], high risk cytogenetics, ≥ 2 cycles to obtain complete remission [CR], erythroblastic or megakaryocytic leukemia; CR2+. All patients must be in CR as defined by hematological recovery, AND <5% blasts by light microscopy within the bone marrow with a cellularity of ≥15%.
- Very high risk pediatric patients with AML. Patients <21 years, however, are eligible with (M2 marrow) with < or = 25% blasts in marrow after having failed one or more cycles of chemotherapy. This group of patients will be analyzed separately.
- Acute lymphocytic leukemia (ALL): high risk CR1 [t(9;22), t (1:19), t(4;11) or other MLL rearrangements] hypodiploidy, or IKZF1 abnormalities), DNA index < 0.81, > 1 cycle to obtain CR or presence minimal residual disease (MRD). Patients in CR2+ are eligible. All patients must be in CR as defined by hematological recovery, AND <5% blasts by light microscopy within the bone marrow with a cellularity of ≥15%.
- Very high risk pediatric patients with ALL. patients <21 years are also considered high risk CR1 if they had M2 or M3 marrow at day 42 from the initiation of induction or M3 marrow at the end of induction. They are eligible once they achieved a complete remission
- Chronic myelogenous leukemia (CML) excluding refractory blast crisis. To be eligible in first chronic phase (CP1) patient must have failed or be intolerant to imatinib mesylate.
- Plasma Cell leukemia after initial therapy, who achieved at least a partial remission
- Advanced myelofibrosis
- Myelodysplasia (MDS) IPSS Int-2 or High risk (i.e. RAEB, RAEBt) or refractory anemia with severe pancytopenia or high risk cytogenetics. Blasts must be < 10% by a representative bone marrow aspirate morphology.
- Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), marginal zone B-cell lymphoma or follicular lymphoma are eligible if there was disease progression/relapse within 12 of achieving a partial or complete remission. Patients who had remissions lasting > 12 months, are eligible after at least two prior therapies. Patients with bulky disease (nodal mass greater than 5 cm) should be considered for debulking chemotherapy before transplant.
- Lymphoplasmacytic lymphoma, mantle-cell lymphoma, prolymphocytic leukemia are eligible after initial therapy in CR1+ or PR1+.
- Large cell NHL > CR2/> PR2. Patients in CR2/PR2 with initial short remission (<6 months) are eligible.
- Lymphoblastic lymphoma, Burkitt's lymphoma, and other high-grade NHL after initial therapy if stage III/IV in CR1/PR1 or after progression if stage I/II < 1 year.
- Multiple myeloma beyond PR2. Patients with chromosome 13 abnormalities, first response lasting less than 6 months, or β-2 microglobulin > 3 mg/L, may be considered for this protocol after initial therapy.
- Organ function and Performance Status Criteria
- Recipients must have a Karnofsky score (adults) ≥ 80 % or Lansky score ≥ 50% (pediatrics) and have acceptable organ function defined as:
- Renal: creatinine < or = 2.0 (adults) or creatinine clearance > 40 ml/min (pediatrics)
- Hepatic: bilirubin, aspartate aminotransferase/alanine aminotransferase (AST/ALT), Alkaline phosphatase (ALP) < or = 5 x upper limit of normal
- Pulmonary function: Diffusion capacity corrected (DLCOcorr) > 50% normal
- Cardiac: left ventricular ejection fraction > or = 45%.
