(<strong>NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/ADIL">ADIL</a></strong>) ("Adial" or the "Company"), a clinical-stage biopharmaceutical company focused on developing therapies for the treatment and prevention of addiction and related disorders, today announced the filing of a new U.S. utility application with the United States Patent and Trade Office (USPTO) directed to AD04, the Company's lead investigational genetically targeted, serotonin-3 receptor antagonist, therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in heavy drinking patients. Once the patent is granted, it is expected to protect Adial's core assets through at least 2045.</p>  <p align="justify">The application is being filed with a Request for Track One Prioritized examination to expedite examination. The advantages of a Track One Prioritized examination include a substantially shorter examination time that will assist Adial with early patentability insights to refine strategy and a condensed prosecution.</p>  <p align="justify">Cary Claiborne, President and Chief Executive Officer of Adial, commented, "As we advance the AD04 program toward its next clinical phase, this patent application represents a meaningful step in strengthening and extending the long-term value of our intellectual property portfolio. If the patent is granted, it is expected to secure protection for our core assets through at least 2045, reinforcing the durability of our potential commercial opportunity."</p>  <p align="justify">"This application reflects a comprehensive post hoc analysis of our data and demonstrates our disciplined approach to maximizing asset value. It enhances our strategic positioning as we approach potential commercialization—both by supporting early enforcement capabilities and by increasing the attractiveness of AD04 in ongoing licensing discussions. We believe the potential for extended exclusivity meaningfully strengthens our negotiating position with prospective partners and enhances the overall value proposition of AD04 for U.S. and global commercialization opportunities."</p>  <p><strong>About Adial Pharmaceuticals, Inc.</strong></p>  <p>Adial Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development of treatments for addictions and related disorders.
