About
This phase I trial studies the side effects and best way to give natural killer cells and donor umbilical cord blood transplant in treating patients with hematological malignancies. Giving chemotherapy with or without total body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer 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.
Full description
PRIMARY OBJECTIVES:
I. To evaluate the feasibility and safety of ex-vivo expanded cord blood (CB) natural killer (NK) cells with double CB transplantation in patients with hematological malignancies.
SECONDARY OBJECTIVES:
I. To monitor engraftment, chimerism, graft versus host disease, and immune reconstitution in patients receiving expanded CB NK cell therapy.
II. To estimate the time to platelet recovery and the time to absolute neutrophil count (ANC) recovery.
III. To estimate overall survival and disease free survival at one year. IV. To study the in-vivo persistence of cord blood NK cells.
OUTLINE:
PREPARATIVE REGIMEN: Patients are assigned to 1 of 2 treatment plans:
TREATMENT PLAN 1: Patients receive high-dose lenalidomide orally (PO) once daily (QD) on days -8 to -2, fludarabine phosphate IV over 1 hour on days -7 to -4, and melphalan IV over 30 minutes on day -4. CD20 positive patients also receive rituximab intravenously (IV) over 6 hours on days -8 to -4.
TREATMENT PLAN 2: Patients receive high-dose lenalidomide PO QD on days -7 to -2, cyclophosphamide IV over 3 hours on day -7, and undergo total body irradiation (TBI) on day -3. Patients also receive rituximab and fludarabine phosphate as in Treatment Plan 1.
NK CELL INFUSION: All patients receive ex-vivo expanded cord blood NK cells IV over 30 minutes on day -2.
TRANSPLANT: All patients undergo allogeneic umbilical cord blood transplant on day 0.
GRAFT-VERSUS-HOST DISEASE (GVHD) PROPHYLAXIS: All patients receive tacrolimus IV or PO on days -2 to 180 followed by taper and mycophenolate mofetil IV over 2 hours or PO thrice daily (TID) on days -3 to 100.
After completion of study treatment, patients are followed up at 3, 6, and 12 months.

- Myelodysplastic syndrome (MDS): primary or therapy related
- Acute lymphoblastic leukemia (ALL): induction failure, primary refractory to treatment (do not achieve complete remission after first course of therapy) or are beyond first remission including second or greater remission or active disease; patients in first remission are eligible if they are considered high risk, defined as any of the following detected at any time: with t(9;22) or t(4;11), hypodiploidy, complex karyotype, secondary leukemia developing after cytotoxic drug exposure, and/or evidence of minimal residual disease, or acute biphenotypic leukemia, or double hit non-Hodgkin's lymphoma

- All study participants must be registered into the mandatory Revlimid Risk Evaluation and Mitigation Strategy (REMS) program, and be willing and able to comply with the requirements of the Revlimid REMS program
- Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS program
- Negative beta human chorionic gonadotropin (HCG) test in a woman with child bearing potential defined as not post-menopausal for 24 months or no previous surgical sterilization and willing to ongoing pregnancy testing while on treatment with lenalidomide
- Woman with child bearing potential must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 4 weeks before she starts taking lenalidomide
- Men must agree to use a latex condom during sexual contact with females of child bearing potential even if they have had a successful vasectomy
- Patients must have two CB units available which are matched with the patient at 4, 5, or 6/6 human leukocyte antigen (HLA) class I (serological) and II (molecular) antigens; each cord must contain at least 1.5 x 10^7 total nucleated cells/Kg recipient body weight (pre-thaw); cord blood units will be procured through the National Marrow Donor Program (NMDP)
- Have identified a backup cells source in case of engraftment failure; the source can be autologous, related or unrelated
- Patients who have had a prior autologous transplant are eligible
Exclusion criteria
- Patients with known history of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS)
- Active central nervous system (CNS) disease in patient with history of CNS malignancy
