Memory-like natural killer cells(Washington University School of Medicine)

This phase I/II pilot study aims to enhance the effectiveness of stem cell transplant for children and young adults with high-risk acute myeloid leukemia (AML). Patients will undergo a stem cell transplant from a half-matched family donor. One week later, patients will receive an additional infusion of immune cells and a drug called interleukin-2.
To mitigate the potential complications associated with graft-versus-host-disease, the donated stem cell product undergoes a process that removes a specific type of immune cell. After transplant, recipients are administered additional immune cells known as memory-like natural killer (ML NK) cells. These cells are derived by converting conventional natural killer cells obtained from the donor.
The infusion of a modified stem cell product, along with administration of ML NK cells may help prevent the development of GvHD while simultaneously improving the efficacy of the treatment.
