About

about nkarta

Nkarta seeks to improve upon the efficacy of cell therapy, making it more potent, better tolerated and more rapidly available to a broad population of patients with life-threatening cancers and autoimmune diseases.

While T-cell therapy, often known as CAR-T, has proven successful in certain cancer indications, its promise has been limited to a few hematologic malignancies and the side effects can be severe. Natural Killer cells are the immune system’s first responders against diseases and pathogens. Unlike T cells, they have an inherent ability to target tumor cells without genetic alteration, and therefore hold significant promise in the development of potent therapies that can be used more readily for diverse tumor types. Nkarta’s differentiated cell therapy approach is designed to boost and enhance the inherent power of Natural Killer cells to target and destroy tumor cells, while also offering a better tolerated safety profile.
