bluebird bio and Gritstone Oncology Announce Strategic Collaboration to Develop Novel Cancer Cell Therapies

CAMBRIDGE, Mass. & EMERYVILLE, Calif.--(BUSINESS WIRE)--Aug. 23, 2018-- bluebird bio, Inc. (Nasdaq: BLUE) and Gritstone Oncology, Inc. today announced a collaboration to research, develop and commercialize products for the treatment of cancer using cell therapy. Gritstone Oncology will leverage its proprietary EDGE™ artificial intelligence platform to analyze specific tumor types to identify tumor-specific targets and natural T-cell receptors (TCRs) directed to those targets for use in bluebird bio’s established cell therapy platforms. bluebird bio will conduct all development, manufacturing and commercial activities. Gritstone Oncology will utilize its proprietary technology platform to enable patient selection for clinical development of such therapies.

“By combining our expertise in gene and cell therapy with Gritstone Oncology’s unique target identification and TCR technology, we hope to bring the power of cell therapy to a broader set of newly-validated targets, enabling us to treat previously unaddressable patient populations,” said Philip Gregory, D.Phil., chief scientific officer of bluebird bio. “As we expand our immuno-oncology focus and portfolio, this collaboration with Gritstone Oncology is highly complementary to our goal of rapidly advancing novel cellular therapies with the potential to transform the lives of people with cancer, particularly in solid tumor indications.”

“As the field of immuno-oncology has evolved, it has become clear that targeting T-cell therapeutics to solid tumors in a highly specific manner is vital to enable potent tumor cell killing with sparing of normal tissues,” said Andrew Allen, M.D., Ph.D., president and chief executive officer of Gritstone Oncology. “We believe that our artificial intelligence-based approach to identifying tumor-specific targets and corresponding, naturally occurring TCRs, combined with bluebird bio’s expertise in gene and cell therapy, will allow us to develop cellular immunotherapies against differentiated oncology targets. We look forward to collaborating with the bluebird bio team in order to develop innovative treatments for patients in need.”

Under the terms of the agreement, Gritstone Oncology will provide 10 tumor-specific targets across several tumor types and, in certain cases, TCRs directed to those targets to bluebird bio. Gritstone Oncology will receive $20 million in an upfront payment and an additional $10 million in the form of a Series C preferred equity investment. In addition, Gritstone Oncology is eligible for significant development, regulatory and commercial milestones on any therapies, and tiered royalties on certain approved therapies.

About Gritstone Oncology, Inc.
Gritstone Oncology is developing tumor-specific cancer immunotherapies to fight multiple cancer types. The company has built its approach on two key pillars—first, a proprietary machine learning-based platform, Gritstone EDGE™, which provides the 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. Gritstone brings together distinguished scientific founders, an experienced and diverse management team, a seasoned and successful board of directors and deep financial backing from Versant Ventures, The Column Group, Clarus Funds, Frazier Healthcare Partners, Redmile Group, Casdin Capital, Lilly Asia Ventures, Trinitas Capital, GV, Alexandria Venture Investments and Bay City Capital.
