Summary
Brief summary (as posted)
The purpose of this research study is to determine if the GM-K562/leukemia cell vaccine can be safely given soon after allogeneic marrow or blood stem cell transplant. The GM-K562/leukemia cell vaccine is composed of a cultured cell line that has been genetically modified to secrete GM-CSF, a naturally occuring substance in the body that stimulates the immune system. The vaccine is a mixture of the GM-K562 cells (radiated to prevent them from growing in the participants body) with the participant's previously frozen and killed leukemia cells. By mixing the GM-K562 with the leukemia cells, we would like to study whether this vaccine combination will stimulate the participant's new immune system to recognize and fight against their MDS/AML cancer cells.
