Randomized Study of Haploidentical Hct and Subsequent Donor nk Cell Infusion in High-risk AML and MDS

"Patients in the study arm will receive donor NK cell infusion around days 13 and 20. A permissible range of infusion time will be +/- 3 days.~For DNKI to be given on day 13 (DNKI-1), the cell dose is 1-2 x108/kg or about the half of amount generated. For DNKI to be given on day 20 (DNKI-2), the cell dose is up to 5x108/kg.~Avil 1 ampoule will be given intravenously 30 minutes prior to each NK cell infusions."
