Safety and Efficacy of Allogeneic NK Cell Infusions in Patients With Relapsed/Refractory AML and High Risk MDS

This study involves the use of an investigational cell therapy known as DVX201. DVX201 is an investigational cell therapy that contains a type of white blood cell called natural killer (NK) cells. NK cells are a normal part of your immune system and have a lifespan of only about two weeks. They are called natural killer cells because they have the natural ability to identify and kill cells in the body that are abnormal, like cancer cells or virally infected cells. But fighting cancer can also lead to exhaustion and abnormal function of NK cells. It can also result in a significant decrease in the number of NK cells in the blood, making it more difficult for the immune system to control the disease. We believe that infusion of healthy, functional NK cells into patients with AML or MDS may boost the immune system and help by killing cancer cells that remain after chemotherapy. DVX201 is an investigational NK cell therapy that may provide a rapid and temporary source of healthy NK cells that are better able to fight those cancer cells.
