Making good on ambitions to increase its say in the development of drug candidates from its AI-driven discovery platform, as well as the breadth of roles the system serves, Exscientia plc said Jan. 7 it will work with longtime partner Sanofi SA to develop up to 15 new small-molecule candidates for oncology and immunology indications. Sanofi will pay Exscientia $100 million up front and up to $5.2 billion in total milestones, plus tiered royalties, it said.
