Adial Pharmaceuticals to Announce Topline Results of ONWARD™ Phase 3 Trial for AD04 in Patients With Alcohol Use Disorder

Company to host conference call on Wednesday, July 20, 2022, at 1 PM ET

CHARLOTTESVILLE, Va., July 18, 2022 — Adial Pharmaceuticals, Inc. (NASDAQ: ADIL; ADILW) (“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 that it plans to report topline results from the Company’s ONWARD™ Phase 3 clinical trial on Wednesday, July 20, 2022. The Company plans to host a conference call at 1 PM Eastern Time on Wednesday (dial-in instructions to follow).

About the ONWARD™ Trial

The ONWARD Phase 3 clinical trial is a 24-week, multicenter, randomized, double-blind, placebo-controlled, parallel group, clinical study to evaluate the efficacy, safety and tolerability of AD04 in patients with Alcohol Use Disorder and selected polymorphisms in the serotonin transporter and receptor genes. Patients were genetically screened prior to enrollment in ONWARD so that only genetically positive patients were enrolled. Approximately one-third of the screened patients tested genetically positive for the targeted genetics, and patients were stratified by the severity of drinking into heavy drinkers and very heavy drinkers (determined by whether they averaged less than ten, or greater than or equal to ten drinks per drinking day, respectively, prior to enrollment). Approximately, two-thirds of the patients in the ONWARD trial were in the heavy drinking group and one-third in the very heavy drinker group.

ONWARD was conducted in 25 clinical sites in six countries in Scandinavia and Central and Eastern Europe (Sweden, Finland, Poland, Latvia, Bulgaria and Croatia). The principal investigator is Professor Hannu E.R. Alho, Emeritus Professor of Addiction Medicine at the University of Helsinki.

About Adial Pharmaceuticals, Inc.

Adial Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development of treatments for addictions. 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) and was recently investigated in the Company’s landmark ONWARD™ Phase 3 clinical trial for the potential treatment of AUD in subjects with certain target genotypes (estimated to be approximately one-third of the AUD population) identified using the Company’s proprietary companion diagnostic genetic test. A Phase 2b clinical trial of AD04 for the treatment of AUD showed promising results in reducing frequency of drinking, quantity of drinking and heavy drinking (all with statistical significance), and no overt safety concerns (there were no statistically significant serious adverse events reported). AD04 is also believed to have the potential to treat other addictive disorders such as Opioid Use Disorder, gambling, and obesity. The Company is also developing adenosine analogs for the treatment of pain and other disorders. Additional information is available at
