Actual (reported)This phase I trial studies the side effects of donor natural killer (NK) cell therapy in treating patients with acute myeloid leukemia that has come back (recurrent) or has not responded to treatment (refractory). Natural killer cells are a type of immune cell. Immunotherapy with genetically modified NK cells from donors may induce changes in the body's immune system and may interfere with the ability of cancer cells to grow and spread.

Actual (reported)Maximum tolerated dose (MTD) of membrane-bound interleukin-21-expanded haploidentical natural killer (NK) cells
The MTD will be defined as the highest safely tolerated dose where at most one patient in six experiences dose-limiting toxicity (DLT) during DLT observation period. DLT is defined as any steroid refractory acute graft versus host disease.
Up to 63 days
Incidence of adverse events
Toxicities will be assessed by type and grade using Common Terminology Criteria for Adverse Events version 5.0 and displayed in summary form by cohort and overall. Toxicities will be summarized and reported regardless of attribution and also only those attributed to NK cells.
Up to day 28
Fludarabine 30 mg/m2/day (day -6 to day -2) and Cytarabine 2g/ m2/day (days -6 to day -2)
Six doses of third-party-donor mbIL-21 expanded (KDS-1001) cells given thrice weekly for two weeks. Days may vary and KDS-1001 can be given from days 0 to 21
