Gritstone Oncology is a clinical-stage biotechnology company developing the next generation of cancer immunotherapies to fight multiple cancer types. Gritstone develops its products by leveraging two key pillars— first, a proprietary machine learning-based platform, Gritstone EDGETM, which is designed to predict, from a routine tumor biopsy, the tumor-specific neoantigens (TSNA) that are presented on a patient’s tumor cells; and second, the ability to develop and manufacture potent immunotherapies utilizing patients’ TSNA to potentially drive the patient’s immune system to specifically attack and destroy tumors. The Company’s individualized neoantigen-based immunotherapy, GRANITE, and its “off the shelf” shared neoantigen-based immunotherapy, SLATE, are being evaluated in clinical studies. Novel tumor-specific antigens can also provide targets for bispecific antibody (BiSAb) therapeutics for solid tumors, and Gritstone’s BiSAb program is currently in lead optimization.
