FOSTER CITY, CA & LEXINGTON, MA, USA I December 20, 2018 I Gilead Sciences, Inc. (NASDAQ: GILD) and Agenus Inc. (NASDAQ: AGEN) announced today the companies have entered into an immuno-oncology (I-O) partnership focused on the development and commercialization of up to five novel immuno-oncology therapies.

The agreement also includes approximately $1.7 billion in potential future fees and milestones. Gilead will receive worldwide exclusive rights to AGEN1423, which has an estimated IND filing by year-end 2018.

“Recent advances in immuno-oncology have produced unprecedented benefit to patients; however, many people with cancer still require more effective treatment options,” said John McHutchison, AO, MD, Chief Scientific Officer and Head of Research and Development, Gilead Sciences. “Our collaboration with Agenus gives us access to novel and differentiated immune modulating antibodies that will complement our growing oncology portfolio and cell therapy business.
