Gritstone Oncology Opens New State-of-the-Art Personalized Cancer Immunotherapy Manufacturing Facility

First Investigational Products Expected to be Manufactured for Clinical Trials by Mid-2018

Emeryville, CA, November 28, 2017 – Gritstone Oncology, a next-generation personalized cancer immunotherapy company, announced today the opening of a new 43,000 square-foot manufacturing facility in Pleasanton, CA.

This fully-operational biomanufacturing facility, which includes multiple clean rooms, each to be deployed for producing therapeutics on an individualized basis, will be the center of Gritstone’s personalized cancer immunotherapy manufacturing efforts. With capacity for further expansion, the Pleasanton facility has been built in compliance with current Good Manufacturing Practices (cGMP) standards. This complements the cGMP-compliant, next-generation sequencing capability based in Cambridge, MA., where Gritstone’s sequencing, informatics and deep learning teams are focused.

The company expects to manufacture its first investigational products at the Pleasanton facility for use in human clinical trials by mid-2018, and will ramp-up its dedicated staff at the facility over the next six months.

“Our team at Gritstone Oncology is focused on a unique vision within cancer immunotherapy development – leveraging the power of deep learning to guide the development of cancer immunotherapies tailored for each patient. We are excited to launch the core of our manufacturing capabilities in Pleasanton (a well-known Bay Area biomanufacturing hub) as we move closer towards the initiation of human clinical trials next year,” said Andrew Allen, M.D., Ph.D., co-founder, president and chief executive officer of Gritstone Oncology.
