Lilly and Aduro Biotech Announce Research Collaboration and License Agreement to Develop Novel Immunotherapies

INDIANAPOLIS and BERKLEY, Calif., Dec. 18, 2018 (GLOBE NEWSWIRE) — Eli Lilly and Company (NYSE: LLY) and Aduro Biotech, Inc. (NASDAQ: ADRO) today announced a research collaboration and exclusive license agreement for Aduro’s cGAS-STING Pathway Inhibitor program for the research and development of novel immunotherapies for autoimmune and other inflammatory diseases.

Aduro’s cGAS-STING Pathway Inhibitor program aims to discover and develop inhibitors of the intracellular stimulator of interferon genes (STING) pathway, which can modulate the immune response associated with various autoimmune diseases. As part of the agreement, Lilly will gain access to novel molecules from Aduro that are designed to inhibit the cGAS-STING pathway. The companies will collaborate to advance these molecules, as well as others from Lilly, into clinical development.

Under the terms of the agreement, Aduro will receive an upfront payment of $12 million and will be eligible for development and commercial milestones up to approximately $620 million per product, as well as royalty payments in the single to low-double digits should Lilly successfully commercialize a therapy from the collaboration. Aduro will receive research funding during the research term and has the option to co-fund the clinical development of each product in exchange for an increase in royalty payments. Lilly will be responsible for all costs of global commercialization.

“At Lilly, we continue to explore new areas of science and are committed to developing novel immunology treatments,” said Ajay Nirula, M.D., Ph.D., vice president of immunology research at Lilly. “We are pleased to collaborate with Aduro, and hope to utilize their expertise with the cGAS-STING pathway to identify promising pathway inhibitors that could one day become breakthrough medicines.”

“As we continue to strengthen our leadership in the STING pathway at Aduro, we are thrilled to collaborate with Lilly to identify and develop novel cGAS-STING pathway inhibitors,” said Stephen T. Isaacs, chairman, president and chief executive officer of Aduro. “This partnership represents an exceptional opportunity to leverage Lilly’s expertise in immunology while expanding the potential for our technology into therapeutic approaches for autoimmune and other inflammatory diseases.”

This transaction will be reflected in Lilly’s reported results and financial guidance according to Generally Accepted Accounting Principles (GAAP). There will be no change to Lilly’s 2018 non-GAAP earnings per share guidance as a result of this transaction.

About Aduro’s cGAS-STING Pathway Inhibitor Program
Aduro’s cGAS-STING Pathway Inhibitor program is based on the inhibition of the intracellular stimulator of interferon genes (STING) pathway that leads to a reduction in the immune response associated with certain autoimmune diseases. Activation of the STING pathway is believed to play a role in the development of an immune response through the induction of proinflammatory cytokines known as type I interferons. Upon inhibition of the STING pathway, the expression of type I interferons is reduced, resulting in a diminution of cytokines and other factors responsible for the activation of the type I interferon-mediated immune response observed in autoimmune disease.

About Aduro 
Aduro Biotech, Inc. is an immunotherapy company focused on the discovery, development and commercialization of therapies that are intended to transform the treatment of challenging diseases. Aduro’s technologies, which are designed to harness the body’s natural immune system, are being investigated in cancer indications, autoimmune diseases and have the potential to expand into infectious diseases. Aduro’s STING pathway activator technology is designed to activate the STING receptor in immune cells, which may result in a potent tumor-specific immune response. ADU-S100 (MIW815) is the first STING pathway activator compound to enter the clinic and is currently being evaluated in a Phase 1 clinical trial as a single agent and in combination with ipilimumab and in a Phase 1b combination trial with spartalizumab (PDR001), an investigational anti-PD-1 monoclonal antibody. Aduro’s B-select monoclonal antibody technology, including BION-1301, an anti-APRIL antibody, is comprised of a number of immune modulating assets in research and development. Aduro is collaborating with leading global pharmaceutical companies to expand its products and technologies. For more information, please visit
