DateStageInvestorsRaisedDeal Summary
Jun 2018Series CRedmile Group (lead)$21MGritstone Bio is a biotechnology company founded in 2015 and based in Emeryville, California, that develops immunotherapies for cancer and infectious diseases. The company's approach centers on personalized tumor-specific neoantigen immunotherapies, leveraging its proprietary EDGE machine learning platform to identify T-cell targets and employing unique delivery systems combining adenovirus-based vectors with self-replicating RNA-based vectors to enhance immune response. Gritstone Bio raised a total of $194.7 million across multiple funding rounds from investors including Redmile Group, Gilead Sciences, Frazier Life Sciences, Versant Ventures, The Column Group, Casdin Capital, Lilly Asia Ventures, Trinitas Capital, GV, Alexandria Venture Investments, and Bay City Capital. The company's lead product candidate GRANITE-001 underwent clinical evaluation for advanced solid tumors in collaboration with Bristol-Myers Squibb, combining Gritstone's personalized neoantigen immunotherapy with Bristol-Myers Squibb's PD-1 immune checkpoint inhibitor. In October 2024, Gritstone Bio filed for bankruptcy after the clinical stage company was unable to advance its pipeline to generate revenue-generating approvals.
Sep 2017Series BBay City Capital (lead); Lilly Asia Ventures (lead); Trinitas Capital; The Column Group; Redmile Group; GV; Alexandria Venture Investments; Versant Ventures; Frazier Healthcare Partners; Clarus Ventures$93MGritstone Oncology (now Gritstone bio), a California-based biotech company founded in 2015, develops personalized cancer immunotherapies using deep learning to identify tumor-specific neoantigens for treatments targeting lung and gastric cancer. The company's platform, Gritstone EDGE, analyzes human tumor molecular data to optimize neoantigen selection for synthetic vaccines designed to prime the immune system, often in combination with checkpoint inhibitors. Their lead program was set to enter clinical trials in mid-2018 for non-small cell lung cancer and gastric cancer. In September 2017, Gritstone closed a $92.7 million Series B financing round, following a $102 million Series A, bringing total funding to nearly $200 million. The round was co-led by Lilly Asia Ventures and Bay City Capital, with participation from GV (formerly Google Ventures), Trinitas Capital, Alexandria Venture Investments, and existing investors Versant Ventures, The Column Group, Clarus Funds, and Frazier Healthcare Partners. Judith Li from Lilly Asia Ventures joined the board post-round. Proceeds were allocated to advance the tumor antigen identification platform, pipeline development, and construction of a personalized immunotherapy manufacturing facility. The experienced team includes CEO Andrew Allen, CTO Roman Yelensky (ex-Foundation Medicine), CSO Karin Jooss (ex-Pfizer), and CMO Raphaël Rousseau (ex-Genentech). The financing reflects investor enthusiasm for Gritstone's AI-driven approach to neoantigen-targeted vaccines amid rising interest in personalized cancer therapies, comparable to FDA-approved cell therapies like Kymriah. GV highlighted the revolutionary potential of Gritstone's deep learning for patient-specific therapeutics.
Oct 2015Series AClarus Ventures (lead); The Column Group (lead); Versant Ventures (lead); Redmile Group; Casdin Capital; Frazier Healthcare Partners; Transformational Healthcare Opportunity$102MGritstone Oncology closed a Series A financing round of $102 million in October 2015, led by Versant Ventures and The Column Group, with additional participation from Clarus Ventures, Frazier Healthcare Partners, Redmile Group, Casdin Capital, and Transformational Healthcare Opportunity. The company was founded by Andrew Allen, former chief medical officer and co-founder of Clovis Oncology, who served as CEO, with Clovis CEO Patrick Mahaffy taking the chairman role. The company's scientific co-founders were Drs. Tim Chan and Naiyer Rizvi, researchers at Memorial Sloan Kettering Cancer Center who had pioneered neoantigen analysis for checkpoint inhibition, alongside Professor Jean-Charles Soria of Institut Gustave Roussy, Professor Graham Lord of King's College London, and Dr. Mark Cobbold of Massachusetts General Hospital. Gritstone developed personalized, tumor-specific neoantigen immunotherapies, creating patient-specific cancer vaccines based on individual neoantigens identified through tumor analysis using its proprietary Gritstone EDGE platform. The company initially focused on non-small cell lung cancer and operated offices in San Francisco and Cambridge, Massachusetts. The $102 million Series A was noted as the third-largest Series A for a biotech company in 2015 and positioned Gritstone as a new entrant in the emerging neoantigen-based cancer vaccine field, competing with other startups like Neon Therapeutics that had launched around the same time with similar approaches.
