“High dose, uninformed, toxic chemotherapy damages the immune system and induces what is known as tolerogenic cell death," said Doctor Patrick Soon-Shiong, the Chair and CEO of NantKwest.
"Natural killer cells are the core innate immuno-protective mechanism against cancer. By developing a system of activating the patient’s own natural killer cells and T cells, as well as augmenting the patient’s NK killing ability with engineering off-the-shelf NK transfusions, we hypothesize that resistant cancer can be overcome," he added.
NantKwest is a clinical-stage immunotherapy company focused on harnessing the power of the innate immune system by using the natural killer cell to treat cancer, infectious diseases and inflammatory diseases.
The company is based in Culver City, California.
