MELBOURNE, Australia, July 3, 2025 /PRNewswire/ -- Neurizon Therapeutics Limited (ASX: NUZ & NUZOA) ("Neurizon" or "the Company"), a clinical-stage biotech company dedicated to advancing innovative treatments for neurodegenerative diseases, is pleased to announce it has executed an exclusive global license agreement with Elanco Animal Health Incorporated (Elanco; NYSE: ELAN) and affiliates for Monepantel, the active pharmaceutical ingredient in NUZ-001, Neurizon's lead investigational therapy in development for Amyotrophic Lateral Sclerosis (ALS) and other neurodegenerative diseases in humans.

This license agreement represents a critical inflection point for Neurizon, further strengthening the Company's strategic outlook for the development, manufacturing and potential future commercialisation of NUZ-001. It also significantly supports the Company's regulatory foundations, providing ongoing access to critical animal safety data and manufacturing data, key pillars required to support future clinical trials, potential regulatory approvals and global market entry.

Dr. Michael Thurn, Managing Director and Chief Executive Officer, commented: "This license agreement with Elanco marks a watershed moment in Neurizon's journey to become a leader in the accelerated development of treatments for neurodegenerative diseases. This strategic milestone provides exclusive access to a comprehensive package of non-clinical studies and manufacturing data, dramatically reducing near-term development costs and accelerating development timelines. All of this is in exchange for a nominal up-front payment, small back-ended regulatory approval and commercial sale milestones and single-digit royalty payments on future global net sales. Neurizon is now well-positioned to accelerate the path to market and advance new treatment options for people affected by devastating neurodegenerative diseases."

Mr. Sergio Duchini, Non-Executive Chairman, commented: "On behalf of the Board, I am pleased to endorse this landmark agreement with Elanco, which represents a strategically significant step forward for Neurizon. This agreement not only strengthens our clinical and regulatory position but also reflects our strong commitment to accelerating the development of meaningful therapies for people living with neurodegenerative diseases. We are also very happy to be making this important step in formalising our relationship with Elanco and look forward to building on this foundation as we progress towards finalising a supply agreement later this year."

Key Terms of the Licensing Agreement:

• Exclusive Global Rights: Neurizon is granted exclusive global rights to Elanco's data package and related intellectual property for monepantel to develop and commercialise NUZ-001 and its related compounds for the treatment, palliation, prevention, or cure of neurodegenerative diseases in humans.
• Upfront Payment: A nominal upfront licensing fee is payable to Elanco upon execution of the agreement^[2].
• Milestone Payments: Total Development milestone payments for the initial and subsequent licensed products, indications, or presentations of US$9.75 million and US$5.2 million, respectively. Elanco will also be eligible for milestone payments of up to US $65 million based on sales milestones^[3].
