Tizona Therapeutics, Inc., is a privately held immunology company harnessing the power of the immune system to develop treatments for cancer and autoimmune disorders. A healthy immune system integrates information from pro-inflammatory and anti-inflammatory cells that regulate the immune system’s function. In cancer, tumor cells evade recognition by controlling cells that suppress the proper function of the immune system. In autoimmune disease, the immune system attacks “self” tissues in the body due to insufficient regulation. Tizona’s therapies are designed to regulate these suppressive cells, thereby either activating the body’s ability to fight cancer or preventing the immune system from attacking healthy tissues in autoimmune diseases.
