NLS Pharmaceutics Ltd., a Swiss clinical-stage biopharmaceutical company focused on the discovery and development of innovative therapies for patients with rare and complex central nervous system (“CNS”) disorders, announced that NLS has entered into an exclusive worldwide option agreement with Aexon Labs, Inc., a privately held U.S. company (“Aexon Labs”), under which NLS may acquire global development and commercialization rights to Aexon Labs’ Dual Orexin Receptor Agonists platform, new molecular entities, highly selective dual oral orexin-1 and orexin-2 receptor agonists (OX1R and OX2R) with potential applications in the treatment of narcolepsy and idiopathic hypersomnia, as well as neurodegenerative disorders such as Parkinson’s and Alzheimer’s disease.
This option agreement represents a potentially leading next-generation, first-in-class, oral, dual orexin receptor agonist (AEX-2) that is expected to address high unmet medical needs and has shown promising results in pre-clinical in vitro assays. Aexon Labs has plans to initiate clinical development, including Phase 1 First-in-Human and Phase 1b Proof-of-Concept (POC) studies, as early as 2024.
The transaction will be structured as an exclusive worldwide license for the development and commercialization by NLS of the Aexon Labs’ compounds and their derivatives. Under the terms of the option agreement, NLS must exercise its option by no later than March 31, 2024. NLS will pay Aexon Labs an upfront payment of $30,000 for the option exclusivity and $170,000 upon execution of the definitive agreement to exercise the option. In addition, Aexon Labs will receive 15% of all proceeds earned by NLS in any future sub-licensing agreements, which include upfront payments, regulatory milestones, commercial milestones and royalties earned during the first three years of commercialization in the U.S. and in the EU. Royalties will be payable on a country-by-country basis from the date of the first commercial sale of a product in a given country until the date of patent expiry or the entry of a generic version of the product in such country.
NLS will be the sole party responsible for the design and execution of the research and development plan, for the conduct and management of the preclinical as well as clinical studies, and for the interactions with the U.S. Food and Drug Administration and/or any other regulatory agency. NLS will pay all costs associated with executing and completing those studies, as well as those associated with the preparation and submission of a new drug application. NLS will pay for all studies in all indications and regulatory filings in the U.S. as well as outside of the U.S.
Eric Konofal, MD, PhD, who works under a part-time consulting agreement for NLS as its Chief Scientific Officer, is the president and founder of Aexon Labs, and owns 59% of Aexon Labs. Alexander Zwyer, Chief Executive Officer of NLS, owns 35% of Aexon Labs. Mr. Zwyer holds no board or executive position at Aexon Labs.
Mr. Zwyer said, “I believe the potential acquisition of this novel and unique platform which consists of over 300 compounds, bridges the present to the future treatment of sleep disorders as well as other neurodegenerative disorders. These new compounds, in addition to our current pipeline, including Mazindol ER for the treatment of narcolepsy, along with NLS-4 focused on idiopathic hypersomnia, long-COVID and chronic fatigue syndrome, and NLS-11, addressing Kleine-Levin Syndrome and neurodegenerative diseases will further complement and strengthen our hypersomnia franchise.”
Orexin receptor pathways play vital regulatory roles in many physiological processes and studies have shown that orexin receptor pathways are involved in pathological processes of neurological diseases such as narcolepsy, depression, ischemic stroke, drug addiction and Alzheimer’s disease.
