NK Cell Infusion for Patients With Acute Myeloid Leukemia

Status Not yet recruiting

Clinical Trial Summary

Natural killer (NK) cells exert antitumor effects via their cytotoxic and cytokine-secreting capacity without present of clinical symptoms. In recent years, with the continuous advancement of in vitro expansion methods, the application of good quality management technology, NK cells could be clinical grade expanded without the need for pre-purification, feeder-free, and serum-free culture. In this clinical trial the investigators want to demonstrate the safety and efficacy chemotherapy combined with donor-derived in vitro activated NK cells infusion for high risk AML patients.

Clinical Trial Description

Despite improvements in new drugs and allogeneic stem cell transplantation (allo-SCT), relapse remains a problem for patients with acute myeloid leukemia (AML). Natural killer (NK) cells exert antitumor effects via their cytotoxic and cytokine-secreting capacity without present of clinical symptoms.

In recent years, with the continuous advancement of in vitro expansion methods, the application of good quality management technology (GMP technology), NK cells could be clinical grade expanded without the need for pre-purification, feeder-free, and serum-free culture. Preclinical studies have confirmed that adoptive infusion expanded and activated NK cells can specifically recognize and kill tumor cells in mice without causing GVHD, which is a safe and effective treatment.

Therefore, in this clinical trial the investigators want to enroll patients with acute AML (excluding APL) who are continued to be unresolved, or relapsed after remission, or continued to be MRD-positive after induction and consolidation according to NCCN standard chemotherapy regimen. Chemotherapy was combined with donor-derived in vitro activated NK cells infusion to evaluate the safety and effectiveness effect of NK cells and to explore the dynamics of NK in vivo after adoptive infusion. ;
