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

Condition or disease Intervention/treatment Phase
Acute Myelogenous Leukemia Acute Lymphoblastic Leukemia Biological: donor natural killer cell infusion Phase 1 Phase 2

Detailed Description:
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.

Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: HLA-Haploidentical Hematopoietic Cell Transplantation and Subsequent Donor Natural Killer Cell Infusion in Refractory Acute Leukemia - A Phase 1-2a STUDY
Study Start Date : February 2013
Actual Primary Completion Date : May 2015
Actual Study Completion Date : May 2015



Intervention Details:
  • Biological: 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.


Primary Outcome Measures :
  1. occurrence and severity of side effects of donor natural killer cell infusion [ Time Frame: 1 year ]

Secondary Outcome Measures :
  1. anti-leukemia effect of donor natural killer cell infusion [ Time Frame: 2 years ]
