Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The protocol treatment is to evaluate clinical effects of donor-derived natural killer cells that are given after HLA-mismatched hematopoietic cell transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Those patients with acute leukemia, which is not responding to coventional chemotherapy, will be treated. The clinical effects will be evaulated in terms of safety (side effects) and anti-leukemia effect.

donor natural killer cell infusion

* Donor NK cells will be generated at the GCP laboratory at Asan Institute of Life Science by a team from Stem Cell Research Center, Korea Research Institute of Bioscience and Biotechnology.
* The patients will receive donor NK cell infusion (DNKI) around on days 6 and 9 (generated from the first collection), and around on days 13 and 20 (generated from the second collection).
* For DNKI to be given on days 6 and 9, a 3-patient cohort each will receive escalating dose of 2x10e7/kg, 5x10e7/kg, 1x10e8/kg, and 1-4 x10e8 cells.
* The dose of DNKI to be given on days 13 and 20 will be 1-4 x10e8/kg.

Intervention Type BIOLOGICAL

Eligibility Criteria
