Cyclophosphamide, Fludarabine Phosphate, and Total-Body Irradiation with or without Anti-Thymocyte Globulin before Donor Umbilical Cord Blood Transplant in Treating Patients with Hematologic Cancer

Trial Status: Active

This phase II trial studies the side effects of cyclophosphamide, fludarabine phosphate, and total-body irradiation with or without anti-thymocyte globulin before donor umbilical cord blood transplant and to see how well they work in treating patients with hematologic (blood) cancer. Giving chemotherapy and total-body irradiation before donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer 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 (called graft-versus-host disease). Giving sirolimus and mycophenolate mofetil before and after the transplant may stop this from happening.

  • Lymphoplasmacytic lymphoma, mantle-cell lymphoma, prolymphocytic leukemia are eligible after initial therapy if chemotherapy sensitive
  • Relapsed multiple myeloma that is chemotherapy sensitive and has failed or ineligible for an autologous transplant
  • Plasma Cell Leukemia after initial therapy if achieved at least in partial remission; or relapsed and achieved subsequent remission (CR/PR)
  • Acquired bone marrow failure syndromes, except for Fanconi anemia
  • Myeloproliferative neoplasms/myelofibrosis
  • Additional criteria for bulky disease (lymphomas): *If stable disease is best response, the largest residual nodal mass must < 5 cm (approximately) *If response to previous therapy, the largest residual mass must represent a 50% reduction and be < 7.5 cm (approximately)
  • Absence of decompensated congestive heart failure, or uncontrolled arrhythmia and left ventricular ejection fraction >= 40%; for children that are not able to cooperate with multi-gated acquisition scan (MUGA) and echocardiography, such should be clearly stated in the physician’s note

  • Transaminases =< 5 x upper limit of normal (ULN) and total bilirubin =< 2.5 mg/dL except for patients with Gilbert’s syndrome or hemolysis
  • Creatinine =< 2.0 mg/dl (adults) and creatinine clearance >= 40 mL/min (pediatrics); adults with a creatinine > 1.2 mg/dl or a history of renal dysfunction must have estimated creatinine clearance >= 40 ml/min/1.73m^2

OUTLINE: Patients are assigned to 1 of 2 arms.


ARM I: Patients who have received a previous autologous transplant or >= 2 courses of chemotherapy within 3 months, receive fludarabine phosphate intravenously (IV) over 1 hour on days -6 to -2 and cyclophosphamide IV over 2 hours on day -6. Patients also undergo total body irradiation (TBI) on day -1.

ARM II: Patients who have not received a previous autologous transplant or =< 1 course of chemotherapy within 3 months, receive fludarabine phosphate, cyclophosphamide, and undergo TBI as in Arm I. Patients also receive anti-thymocyte globulin IV every 12 hours on days -6 to -4 for a total of 6 doses.

UMBILICAL CORD BLOOD (UCB) INFUSION: In both arms, patients undergo unrelated donor umbilical cord blood transplant on day 0.

GVHD PROPHYLAXIS: In both arms beginning on day -3, patients receive sirolimus orally (PO) with a taper starting on day 100 and completed by day 180. Beginning day -3, patients also receive mycophenolate mofetil IV or PO for up to day 30.

After completion of study treatment, patients are followed up for 2 years after transplantation.
