Adial Announces Positive Pre-Clinical Data for its Adenosine Pain Platform
Data merits further testing for pain reduction as a possible alternative to opioids
Validation of Purnovate acquisition
CHARLOTTESVILLE, Va., July 14, 2021 — Adial Pharmaceuticals, Inc. (NASDAQ: ADIL; ADILW), a clinical-stage biopharmaceutical company focused on the development of treatments for addictions, today announced advancements related to its adenosine analog development platform being developed by Purnovate, Inc., a division of Adial Pharmaceuticals, Inc.
- Compounds have been developed that are potent against specifically targeted adenosine receptors while being selective over the adenosine A1 receptor, which is known to have cardiovascular and central nervous system effects that can be problematic for many therapeutic indications. Historically, when selectivity has been achieved over the A1 receptor, water solubility has decreased, making effective tissue distribution in the human body (made largely of water) difficult to achieve and the compounds difficult or impossible to develop as drugs.
- Solubility more than 50 times greater than other known selective adenosine compounds of the same class has been demonstrated.
- Testing to date indicates good oral bioavailability so that oral administration (e.g., tablets) is likely to be one of the options for dosing these compounds.
- Initial animal studies indicate the compounds to be pharmacologically active.
- Multiple compounds have demonstrated a meaningful in vivo reduction in pain (rodents).
- All tested compounds appear synergistic with morphine.
- Certain compounds with higher solubility appear synergistic with acetaminophen (Tylenol).
- In vivo studies suggest that certain compounds may have effects against insulin insensitivity, which makes them potential candidates for licensing or partnership.
- Purnovate is establishing relationships to test its compounds in models of asthma, cancer, and inflammation, also with the intent of licensing products that show initial success or advancing partnerships.
Dr. Robert D. Thompson, Adial’s Vice President, Chemistry, commented, “We are highly encouraged by the latest preclinical data related to our adenosine platform as a potential therapy for pain relief. Based on these data, we are proceeding with development of our compounds to determine if they may have broad implications as a replacement therapy for opioids or, when used in combination, as a way to support lower dose administration of opioids. Importantly, our latest solubility data may be the key to unlocking the potential of adenosine analogs as a therapy. Specifically, while adenosine analogs have been studied extensively over the past five decades, poor solubility has limited the usefulness of this class of compounds as drugs. We believe our proprietary chemistry and solubility technology may also allow for effective oral administration of these compounds, and that our assessment is further supported by the data. Also noteworthy, we studied our adenosine compounds in combination with Tylenol and demonstrated enhanced pain reduction and duration of pain relief in vivo.”
William Stilley, Adial’s Chief Executive Officer, commented, “We believe there may be a number of potential lead compounds in the current inventory of novel chemical entities further bolstered by patent applications. Our unique chemistry and solubility technology may provide a broad, novel and patentable approach that could firmly establish our position as a leader in the field of pain management. We have also identified other potential physiological benefits, including increased insulin sensitivity, which could result in licensing or partnership opportunities. We are excited to advance these programs and view this latest data as a strong validation of our Purnovate acquisition, which we believe helps further advance our goal of becoming the leading biopharmaceutical company in the addiction space. Our mission is not only treating addiction, but addressing the root causes of addiction, including the systemic overuse of opioids, which has contributed to the current addiction pandemic.”
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. Purnovate, Inc., a division of Adial Pharmaceuticals, is developing adenosine analogs for the treatment of pain and other disorders. Additional information is available at www.adialpharma.com.
About the Landmark ONWARD™ Pivotal Phase 3 Clinical Trial
The ONWARD trial is a 24-week, multicenter, randomized, double-blind, placebo-controlled, parallel group, 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 seven countries in Scandinavia and Central and Eastern Europe (Sweden, Finland, Poland, Latvia, Estonia, Bulgaria and Croatia). The principal investigator is Professor Hannu E.R. Alho, Emeritus Professor of Addiction Medicine at the University of Helsinki.
