Natural Killer Cells KDS-1001 to Decrease Disease Relapse in Patients with High-Risk Myeloid Malignancies Undergoing Donor Stem-Cell Transplants
This phase II trial studies the safety and effectiveness of giving natural killer cells KDS-1001 in combination with a standard donor stem cell transplant to patients with acute myeloid leukemia, myelodysplastic syndrome MDS, or chronic myeloid leukemia (high-risk meyloid malignancies). KDS-1001 is created using certain immune cells called natural killer (NK) cells, collected from a third party donor. Adding KDS-1001 to a standard donor stem cell transplant may help control myeloid malignancies.

Patients with intermediate-1 features should have failed to respond to hypomethylating agent therapy, or patients with treatment-related MDS. Patients must have less than 10% bone marrow blasts * Chronic myeloid leukemia (CML): ** Failed to achieve cytogenetic remission or have cytogenetic relapse after treatment with at least 2 tyrosine kinase inhibitors, or ** Accelerated phase or blast phase at any time. ** Intolerant of available tyrosine kinase inhibitors (TKIs)

PRIMARY OBJECTIVE:
I. Assess the safety and effectiveness of “off the shelf” third party natural killer (NK) cells in combination with allogeneic stem cell transplantation (SCT) in patients with myeloid malignancies.
SECONDARY OBJECTIVES:
I. To assess NK cell related toxicities.
II. To estimate the proportion of patients with engraftment/graft failure.
III. To assess the rate of leukemia relapse, disease-free survival (DFS), overall survival (OS), and graft-versus-host disease (GVHD)-free, relapse-free survival (GRFS) after transplantation by one year.
IV. To estimate the non-relapse mortality (NRM) at day 100, day 180 and 1 year post-transplant.
V. To estimate the cumulative incidence of grade 2-4 and grades 3-4 acute (a)GVHD at day 100.
VI. To assess the rate of chronic GVHD within the first-year post transplantation.
VII. To assess rate of BK virus (BK), cytomegalovirus (CMV), and adenovirus infections.
VIII. To assess minimal residual disease (MRD).
IX. To assess immune reconstitution post-transplant.
OUTLINE:
CONDITIONING REGIMEN: Patients receive melphalan intravenously (IV) over 30 minutes on days -6 and -7, fludarabine phosphate IV over 60 minutes on days -7 to -4, total body irradiation (TBI) on day -3 (receipt of TBI dependent on type of transplant), and KDS-1001 IV over 30 minutes on day -2.
TRANSPLANT: Patients undergo donor SCT on day 0.
POST-TRANSPLANT TREATMENT: Patients receive cyclophosphamide IV over 3 hours on days 3 and 4. Patients may also receive KDS-1001 IV over 30 minutes on days 7 and 28.
GVHD PROPHYLAXIS: Patients receive mycophenolate mofetil orally (PO) three times daily (TID) until day 35 and tacrolimus IV once daily (QD) until able to take PO until day 180, tapering off over at least 3 weeks. Patients also receive filgrastim subcutaneously (SC) QD starting on day 7 until neutrophil recovery.
After completion of study treatment, patients are followed up for 1 year.
