Chemotherapy and a Donor Natural Killer Cell Infusion in Treating Patients With Relapsed or Persistent Leukemia or Myelodysplastic Syndrome After a Donor Stem Cell Transplant

• Status: Completed
• Trial end date: 2015-07-01

Summary

The goal of this study is to see if there is a benefit to giving chemotherapy and then natural killer (NK) cells. The NK cells must come from a family member who shares half of the patients HLA proteins. NK cells are a type of white blood cell. They can recognize and kill abnormal cells in the body.

Patients whose blood cancer is not cured with a stem cell transplant do not have standard treatment options. Studies have shown that NK cells from a donor can be given safely and can be helpful in treating some blood diseases. These NK cells are collected from the patients donor and purified using a separation system called CliniMACS that has been used safely in previous studies and is used in this study with the approval of the Federal Food and Drug Administration. The researchers want to find out what effects the NK cells will have on blood cancer and bone marrow function and how to maximize its benefits in treating blood cancers. The researchers hope that giving chemotherapy and then NK cells will be a better treatment for the disease than the current available treatment options.
