About Gritstone Oncology
Gritstone Oncology is developing tumor-specific cancer immunotherapies to fight multiple cancer types. The company has built its tumor-specific immunotherapy approach on two key pillars—first, a proprietary machine learning-based platform, Gritstone EDGE™, which provides a powerful ability to predict from a routine tumor biopsy the tumor-specific neoantigens, or TSNA, that are presented on a patient’s tumor cells; and second, the ability to develop and manufacture potent immunotherapies utilizing patients’ TSNA to drive the patient’s immune system to attack and destroy tumors.
