Summary

RATIONALE: Drugs used in chemotherapy, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill cancer cells. An umbilical cord blood transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and radiation therapy. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving sirolimus and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation followed by an umbilical cord blood transplant, sirolimus, and mycophenolate mofetil works in treating patients with hematologic cancer.

Detailed description: OBJECTIVES: Primary

- Determine the one- and two-year survival of patients with hematologic malignancies

treated with a nonmyeloablative conditioning regimen comprising fludarabine, cyclophosphamide, and total-body irradiation followed by umbilical cord blood transplantation and post-transplant immunosuppression comprising sirolimus and mycophenolate mofetil. Secondary

- Determine the six-month nonrelapse mortality of patients treated with this regimen.

- Determine the presence of chimerism in patients treated with this regimen at days 21,

60, 100, 180, and 365.

- Determine the incidence of neutrophil engraftment by day 42 in patients treated with

this regimen.

- Determine the incidence of platelet engraftment by six months in patients treated with

this regimen.

- Determine the incidence of grade II-IV and grade III-IV acute graft-versus-host disease

(GVHD) at day 100 in patients treated with this regimen.

- Determine the incidence of chronic GVHD at one year in patients treated with this

regimen.

- Determine the probability of overall survival within one or two years in patients

treated with this regimen.

- Determine the probability of progression-free survival within one or two years in

patients treated with this regimen.

- Determine the incidence of relapse or disease progression within one or two years in

patients treated with this regimen. OUTLINE: This is a nonrandomized study. Patients are stratified into five disease groups: 1. acute myeloid leukemia, myelodysplastic syndromes, chronic myelogenous leukemia [CML] in first chronic phase and second chronic phase [CP2] after myeloid blast crisis; 2. acute lymphoblastic leukemia, Burkitt's lymphoma, CML CP2 post lymphoid blast crisis, 3. large-cell B and T-cell lymphoma, mantle cell lymphoma; 4. chronic lymphocytic leukemia/small lymphocytic lymphoma, prolymphocytic leukemia, marginal zone B-cell lymphoma, follicular lymphoma; 5. Hodgkin's lymphoma and multiple myeloma.

- Nonmyeloablative conditioning: Patients receive fludarabine intravenously on days -6

to - 2 and cyclophosphamide IV on day -6. Patients who did not undergo prior autologous

transplant or who received ≤ 1 course of prior multiagent chemotherapy or no severely immunosuppressive therapy in the past 3 months also receive anti-thymocyte globulin IV

on days - 6 to -4. All patients also undergo total-body irradiation on day -1.

- Umbilical cord blood transplant: Patients undergo umbilical cord blood transplantation

on day 0.

- Post-transplant immunosuppression: Sirolimus will be administered starting at day -3

with 8mg-12mg mg oral loading dose followed by single dose 4 mg/day with a target serum concentration of 3 to 12 mg/mL. Levels are to be monitored 3 times/week in the first 2 weeks, weekly until day +60, and as clinically indicated until day +100 post-transplantation. In the absence of acute GVHD sirolimus may be tapered starting at day +100 and eliminated by day +180 post-transplantation. Patients also receive

mycophenolate mofetil IV on days - 3 to 5 and then orally on days 6-30.

After completion of study treatment, patients are followed periodically for 5 years. PROJECTED ACCRUAL: A total of 320 patients will be accrued for this study.

Eligibility

Minimum age: N/A. Maximum age: 75 Years. Gender(s): Both.

Criteria:

Inclusion Criteria: Age, Graft Cell Dose and Graft HLA Criteria

- Subjects must be <70 years old. Subjects ages ≥ 70 and ≤ 75 may be eligible if they

have a Co-Morbidity Scoring (HCT-CI) score ≤ 2.

- The UCB graft is matched at 4-6 HLA-A, B, DRB1 antigens with the recipient.

- Patients co-enrolled in MT-2006-01 Phase I Study of Infusion of Umbilical Cord Blood

Derived CD25+CD4+ T-Regulatory (Treg) Cells after Non-Myeloablative Cord\Blood Transplantation will receive grafts composed of 2 UCB units. Disease Criteria:

- Acute Leukemias:

- Acute myeloid leukemia: high risk complete remission 1 (CR1) (as evidenced by

preceding myelodysplastic syndrome (MDS), high risk cytogenetics such as those associated with MDS or complex karyotype, > 2 cycles to obtain CR or erythroblastic and megakaryocytic); second or greater CR.

- Acute lymphoblastic leukemia/lymphoma: high risk CR1 as evidenced by high risk

cytogenetics (e. g. t(9;22), t(1;19),t(4;11), other myeloid/lymphoid or mixed lineage leukemia [MLL] rearrangements, hypodiploidy or Ikaros family zinc finger 1 [IKZF1]), > 1 cycle to obtain CR or evidence of minimal residual disease (MRD). Patients in second or greater CR are also eligible.

B-cell lymphoma, follicular lymphoma, which have progressed within 12 months 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 should be considered for debulking chemotherapy before transplant. Patients with refractory disease are eligible, unless has bulky disease and an estimated tumor doubling time of less than one month.

- Lymphoplasmacytic lymphoma, mantle-cell lymphoma, prolymphocytic leukemia are
