AD-04

AD04 Program Aligned with NIAAA's New Inclusion of Non-Abstinence Solutions, Validating Commercial and Government Market PotentialGLEN ALLEN, Va., Oct. 15, 2024 (GLOBE NEWSWIRE) -- Adial Pharmaceuticals, Inc. (NASDAQ: ADIL) (“Adial” or the “Company”), a clinical-stage biopharmaceutical company focused on developing therapies for the treatment and prevention of addiction and related disorders, today applauded the National Institute on Alcohol Abuse and Alcoholism (NIAAA) for its newly updated definition of recovery. The new definition, outlined and emphasized in NIAAA’s 2025 Professional Judgement Budget (PJB) as reported to the U.S. Congress following an original introduction in an NIAAA PJB, emphasizes a broader, non-abstinence approach to recovery, which aligns directly with Adial’s AD04 program, which has the potential to offer patients the flexibility of reducing drinking and/or abstinence. NIAAA’s updated definition underscores a growing clinical outcome goal and recognition that effective recovery solutions need not be solely abstinence based, opening the door to therapeutic options that focus on harm reduction and improved quality of life. AD04, Adial’s lead investigational product for alcohol use disorder (AUD), is designed to support patients seeking flexible treatment that could offer reduction in drinking and/or abstinence recovery paths, making it a promising candidate to meet the evolving market needs. This recognition and further emphasis in the FY 2025 Professional Judgement Budget by NIAAA is validation of Adial’s approach as meeting the NIAAA’s new standard for recovery, broadening Adial’s significant commercial and government market potential. “AD04 is uniquely positioned to provide a therapeutic option for those seeking a reduction in alcohol use and/or complete abstinence,” said Cary Claiborne, CEO of Adial Pharmaceuticals. “With NIAAA’s focus shifting to include non-abstinence recovery approaches, we are optimistic that this will stimulate additional support for programs like AD04, not only within commercial markets but also from government initiatives. The alignment of AD04’s development and the NIAAA’s updated perspective offers a promising future for those suffering from AUD, providing them with more personalized, flexible treatment options.” About Adial Pharmaceuticals, Inc. Adial Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development of therapies for the treatment and prevention of addiction and related disorders. The Company’s lead investigational new drug product, AD04, is a genetically targeted, serotonin-3 receptor antagonist, therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in heavy drinking patients and was recently investigated in the Company’s ONWARD™ pivotal Phase 3 clinical trial for the potential treatment of AUD in subjects with certain target genotypes identified using the Company’s proprietary companion diagnostic genetic test. ONWARD showed promising results in reducing heavy drinking in heavy drinking patients, and no overt safety or tolerability concerns. AD04 is also believed to have the potential to treat other addictive disorders such as Opioid Use Disorder, gambling, and obesity. Additional information is available at www.adial.com.
