Reports Second Quarter 2022 Financial Results

Reported positive topline results for ONWARD™ Phase 3 trial of AD04 for the treatment of Alcohol Use Disorder

Pursuing submission of ONWARD™ results with both European and U.S. regulatory agencies

Actively exploring potential partnership opportunities for AD04

Ended second quarter with cash and cash equivalents of $9.2 million

Charlottesville, VA – August 15, 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 provided a business update and reported its financial results for the second quarter of 2022.

William Stilley, Adial’s Chief Executive Officer, stated, “We recently reported successful results from the ONWARD trial, our Phase 3 clinical study evaluating the efficacy, safety and tolerability of AD04 in patients with Alcohol Use Disorder (“AUD”) and selected polymorphisms in the serotonin transporter and receptor genes. The results showed that AD04 achieved a statistically significant mean reduction in heavy drinking days among the pre-specified group of “heavy drinkers” (avg. <10 drinks per drinking day at baseline), which accounted for approximately two-thirds of the trial population. We did not achieve statistical significance among “very heavy drinkers” (avg. ≥10 drinks per drinking day at baseline) due to the high placebo response among this particularly challenging patient population, which resulted in us not achieving the primary efficacy analysis among the combined population. Nevertheless, given the strength of the data, especially the statistical significance among heavy drinkers, as well as the safety and tolerability of AD04, we have consulted with both key opinion leaders and our regulatory advisors. Based on the feedback, we strongly believe there is a clear path forward to regulatory submission, and we are more encouraged than ever about the potential for commercialization.”

Cary Claiborne, Chief Operating Officer of Adial, further noted, “Moving forward, we are working diligently to submit the ONWARD results to both the U.S. Food and Drug Administration (“FDA”) and the European Medicines Authority (“EMA”). Moreover, we are actively exploring potential partnership opportunities in both the U.S. and Europe. Based on just the heavy drinking population alone, which constitutes the majority of AUD patients, we estimate the addressable U.S. market for AD04 to be in the multi-billion dollar range. Overall, we are very pleased with our progress and look forward to providing updates as additional developments unfold.”
