Eli Lilly Inks $856M Deal with Gate Bioscience for Novel Small-Molecule Drug Class

Eli Lilly has entered into a significant partnership with California-based biotech Gate Bioscience, potentially worth up to $856 million, to develop a new class of small-molecule drugs. The collaboration, announced on July 24, 2025, aims to leverage Gate's proprietary discovery engine to identify and develop "molecular gates" - selective small-molecule drugs designed to eradicate harmful extracellular proteins.

Deal Structure and Financial Details

The agreement includes an undisclosed upfront payment and equity investment in Gate Bioscience, with the remainder of the potential $856 million tied to milestone payments and royalties. This partnership marks Gate's first publicly announced collaboration since its founding in 2021.

Technological Focus and Potential Applications

Gate's innovative approach focuses on creating small-molecule drugs capable of eliminating difficult-to-drug proteins. This technology has the potential to address diseases with high unmet medical needs, including inflammatory conditions, neurodegenerative diseases, and various cancers.

Dr. Jordi Mata-Fink, CEO and co-founder of Gate Bioscience, emphasized the significance of the collaboration, stating, "This collaboration fuels our vision to make molecular gates into medicines. Our drugs eliminate disease-causing proteins at their source with a convenient pill."

Lilly's Strategic Investment in Emerging Biotechs

The partnership with Gate Bioscience is part of Lilly's broader strategy to engage with innovative early-stage biotechs. Gate will receive preclinical R&D support from Lilly ExploR&D, an arm of the pharma giant's Lilly Catalyze360 program. This initiative has previously established partnerships with other cutting-edge biotechs, including siRNA-focused Insitro and antibody specialist Oblique Therapeutics.
