Adial Pharmaceuticals, Inc. announced the U.S. Patent and Trademark Office (USPTO) has mailed a Notice of Allowance for US Patent Application No. 16/784,051, a patent application for the treatment for opioid use disorder (OUD) using AD04. This patent application covers treatment of patients with a specific genetic biomarker for the serotonin-3 receptor.

AD04 is currently being evaluated in the Company's ONWARD trial, which is designed as a Phase 3 clinical study to evaluate the efficacy, safety and tolerability of AD04 in patients with alcohol use disorder (AUD). The Company believes AD04 may also hold significant potential for the treatment of OUD since the physiology and neurotransmitters involved in opioid addiction are similar to alcohol and could be expected to be modulated by a serotonin-3 receptor antagonist.
