Genetically targeted AD04 drug candidate indicates stability at four-year point
as it moves toward Phase 3 clinical trial

CHARLOTTESVILLE, Va., Sept. 12, 2018 — Adial Pharmaceuticals, Inc. (NASDAQ: ADIL; ADILW), a clinical-stage biopharmaceutical company focused on the development of treatments for addiction, today announced successful results related to the stability testing of the clinical trial material for its lead drug candidate, AD04, a genetically targeted therapeutic agent being developed to treat alcohol use disorder (AUD). The program indicated stability at the four-year time point for both the active drug candidate and the placebo tablets that had been previously manufactured for use in clinical trials.

William Stilley, CEO of Adial Pharmaceuticals, stated, “We are pleased with the outcome of this independent drug stability testing, which demonstrated stability at four years. In fact, stability testing exceeded our expectations, and, because of these data, we believe there is a likelihood the product will remain stable through the 5th year. Given these results, we believe the clinical trial material we currently possess will be usable in the upcoming Phase 3 trial, once we update our CMC filings with the FDA. Moreover, the drug product was manufactured through a process and at a scale that we believe could be used to support a commercial product. This was an important step in moving toward commencing the Phase 3 trial on time, on budget and to eventual commercial launch.”

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 candidate, AD04, is a genetically targeted therapeutic agent for the treatment of alcohol use disorder (“AUD”). 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). The Company plans to commence a Phase 3 clinical trial using AD04 for the potential treatment of AUD in subjects with certain target genotypes, which are to be identified using the Company’s proprietary companion diagnostic genetic test. AD04 is also believed to have the potential to treat other addictive disorders such as opioid use disorder, gambling, and obesity.

About Alcohol Use Disorder

According to an article in the widely respected publication The Lancet, alcohol is the number one cause of death globally among both men and women ages 15 to 49 years. In the United States alone, approximately 35 million people have AUD resulting in significant health, social and financial costs (NIAAA Alcohol Facts & Statistics). AUD contributes to over 200 different diseases, and 10% of children live with a person that has an alcohol problem. According to the American Society of Clinical Oncologists, 5-6% of new cancers and cancer deaths globally are directly attributable to alcohol. The Centers for Disease Control (the “CDC”) has reported that AUD costs the U.S. economy about $250 billion annually, with heavy drinking accounting for greater than 75% of the social and health related costs. In addition, according to the NIAAA, the problem in the United States appears to be growing with an approximately 50% increase in AUD prevalence between 2002 and 2013.

Despite the high prevalence and high costs, according to an article in the JAMA 2015 publication, only 7.7% of patients (i.e., approximately 2.7 million people) with AUD are estimated to have been treated in any way and only 3.6% by a physician (i.e., approximately 1.3 million people). The most common treatments for AUD are directed at achieving abstinence and typical treatments include psychological and social interventions. Most therapies require abstinence even prior to initiating therapy. Abstinence requires dramatic lifestyle changes often with serious work and social consequences. Significant side effects of current pharmacologic therapies include mental side effects such as psychiatric disorders and depressive symptoms and physical side effects such as nausea, dizziness, vomiting, abdominal pain, arthritis and joint fitness. These problems with the currently available therapies appear to limit the willingness of people with AUD to seek treatment and then to limit compliance with treatment requirements and, therefore, the ultimate results for many people attempting currently available therapies.
