• Candidate RIPK1 inhibitor molecules have the potential to treat Alzheimer鈥檚 disease, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and systemic inflammatory diseases
• Denali to receive $125 million upfront payment and future milestone payments that could exceed $1 billion
• Denali and Sanofi plan to jointly develop and commercialize programs for neurological indications, and Sanofi will develop and commercialize programs for systemic inflammatory indications

SOUTH SAN FRANCISCO, Calif., Nov. 01, 2018 (GLOBE NEWSWIRE) -- Denali Therapeutics Inc. (NASDAQ: DNLI), a biopharmaceutical company developing a broad portfolio of therapeutic candidates for neurodegenerative diseases, today announced that it will collaborate with Sanofi on the development of multiple RIPK1 inhibitor molecules with the potential to treat a range of neurological and systemic inflammatory diseases.

The two lead molecules DNL747 and DNL758 target a critical signaling protein known as the receptor-interacting serine/threonine-protein kinase 1 (RIPK1) in the TNF receptor pathway, which regulates inflammation and cell death in tissues throughout the body. The companies plan to study DNL747 in Alzheimer鈥檚 disease, amyotrophic lateral sclerosis and multiple sclerosis, and DNL758 in systemic inflammatory diseases such as rheumatoid arthritis and psoriasis.

Under the terms of the agreement, Sanofi will make an upfront cash payment to Denali of $125 million, with future development and commercial milestone payments that could exceed $1 billion. Sanofi and Denali will share commercial profits and losses from DNL747 in the U.S. and China equally, while Denali will receive a royalty from Sanofi for other territories for DNL747 and worldwide for DNL758.

Phase 1b and 2 clinical development costs for DNL747 will be fully funded by Sanofifor MS, ALS, and other neurological indications, except in Alzheimer鈥檚 disease, which will be funded by Denali. Phase 3 trials for all neurological indications will be jointly funded by Sanofi (70%) and Denali (30%). Sanofi will fully fund the clinical development costs for DNL758 in systemic inflammatory diseases.

鈥淭his collaboration with Denali is yet another example of Sanofi鈥檚 commitment to accelerate the development of transformative and best-in-class treatments for patients living with serious illnesses,鈥� said Rita Balice-Gordon, Ph.D., Global Head of Rare and Neurologic Diseases Research at Sanofi. 鈥淲e look forward to working with Denali on the RIPK1 program as we explore the potential of this mechanism in neurologic and inflammatory diseases.鈥�

鈥淩IPK1 is a promising target with the potential to bring disease modifying medicines to patients suffering from neurodegenerative diseases as well as systemic inflammatory diseases. We are very excited to partner with Sanofi and expand our RIPK1 program into new indications,鈥� said Ryan Watts, Ph.D., CEO of Denali. "With its considerable infrastructure and experience in both clinical development and commercial functions, Sanofi is an ideal partner for Denali to maximize the clinical and commercial success of our RIPK1 program.鈥�

RIPK1 Inhibitor Molecules

• DNL747 is a brain-penetrant small molecule inhibitor of RIPK1. It is currently being evaluated in early clinical stage trials, known as Phase 1. Phase 1b studies in Alzheimer鈥檚 disease and ALS patients are expected to commence in the near-term. Denali will lead Phase 2 clinical trials in Alzheimer鈥檚 disease while Sanofi will lead Phase 2 clinical trials in MS and ALS, as well as future Phase 3 trials in all neurological indications.
  
• DNL758 is a small molecule inhibitor of RIPK1 that does not penetrate the brain. Sanofi will lead clinical development activities for all systemic inflammatory diseases. The clinical trials are expected to begin in 2019.

The collaboration also includes additional pre-clinical RIPK1 inhibitor molecules.

The transaction is expected to close in the coming months in accordance with customary regulatory approvals.
