Adial Pharmaceuticals Announces Completion of Last Patient, Last Visit in its ONWARD™ Phase 3 Trial of AD04 for the Treatment of Patients with Alcohol Use Disorder
CHARLOTTESVILLE, Va., Feb. 24, 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 the final patient has completed the last dose and last clinical visit in the Company’s ongoing ONWARD™ Phase 3 trial. ONWARD is evaluating the efficacy, safety and tolerability of AD04 as a therapeutic agent for the treatment of Alcohol Use Disorder (AUD) in persons with certain target genotypes related to the serotonin transporter and receptor genes.
William Stilley, Adial’s Chief Executive Officer, stated, “Last patient, last visit in the ONWARD trial is a major milestone for the Company. As previously announced, we had enrolled 302 patients across 25 clinical sites, exceeding our prior enrollment targets and, therefore, enhancing the statistical power of the trial. The safety data and trial retention rate also suggest a well-tolerated therapy, in contrast to conventional therapies. We are now turning our attention to safety follow-up protocols and close-out activities with the expectation that topline results will be available in the second quarter.”
“Patients suffering from AUD remains a significant yet underserved market, accounting for over 3 million deaths worldwide. Sadly, AUD is also the number one risk factor for death and disability in the U.S., and globally among men and women ages 15 to 49. Given the magnitude of this public health crisis, which has only increased since the start of the pandemic, it is more important than ever to bring AD04 to market for the patients. My sincerest gratitude goes to the patients and clinicians that participated in this important trial,” continued Mr. Stilley. “While the last patient, last visit has occurred, the study will remain blinded until the completion of all safety protocol follow-up activities, site inspections, protocol review and other trial closing procedures and activities. Then the database will be locked and analysis of the data will take place. The goal is to show a statistically significant reduction in the number of days of heavy drinking over the course of the study in patients on active AD04 as compared to the placebo group.”
About the Landmark ONWARD™ Pivotal Phase 3 Clinical Trial
The ONWARD trial is a 24-week, multicenter, randomized, double-blind, placebo-controlled, parallel group, pivotal Phase 3 clinical study to evaluate the efficacy, safety and tolerability of AD04 in patients with Alcohol Use Disorder (AUD) and selected polymorphisms in the serotonin transporter and receptor genes. Patients are genetically screened prior to enrollment in the ONWARD trial so that only genetically positive patients are enrolled. The primary endpoint for analysis of efficacy is the change from baseline in the monthly number of heavy drinking days during the last 8 weeks of the 24-week treatment period. ONWARD is currently being conducted in 25 clinical sites in six countries in Scandinavia and Central and Eastern Europe (Sweden, Finland, Poland, Latvia, Bulgaria and Croatia). The Coordinating 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 is currently being investigated in the Company’s landmark ONWARD™ pivotal Phase 3 clinical trial 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. 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 through its wholly owned subsidiary, Purnovate, Inc.
