Gritstone bio brings together a group of distinguished scientific founders and advisors, a highly experienced and diverse leadership team and a seasoned and successful board of directors to develop the next-generation of vaccines for cancer and infectious disease. With our unique approach to immuno-oncology and infectious diseases, we seek to generate a therapeutic immune response by leveraging insights into the immune system’s ability to recognize and destroy diseased cells by targeting select antigens. We started with a focus on tumor-specific neoantigens and more recently extended our programs to include viral antigens displayed on the surface of virus-infected cells. The biology underlying immune system recognition of targets on the surface of abnormal cells is common to both anti-tumor and anti-viral immunity. Consequently, we believe that activating and directing the immune system to these targets could offer an important opportunity to extend the benefits of immunotherapy for more patients.
