Clinical trial expected to commence in 2022

CHARLOTTESVILLE, Va., Oct. 21, 2021 (GLOBE NEWSWIRE) —  Adial Pharmaceuticals, Inc. (NASDAQ: ADIL; ADILW), a clinical-stage biopharmaceutical company focused on developing therapies for the treatment and prevention of addiction and related disorders, today announced positive data in a pre-clinical model of pain reduction. Based on this positive data, Purnovate, Inc., a wholly owned subsidiary of Adial Pharmaceuticals, Inc., has selected PNV-5030 as the lead compound for its program to develop a drug for the treatment of pain.

PNV-5030 has been tested to be more than 1000-fold selective over the adenosine A1 receptor, which is known to have cardiovascular and central nervous system effects across several 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. However, PNV-5030 has demonstrated solubility more than 50 times greater than other known selective adenosine compounds of the same class. Solubility is often an important characteristic of successful drug candidates, and Purnovate believes solubility is a particularly important characteristic in determining the drug development potential of molecules of this class.

In the most recent study, PNV-5030 was tested in a mouse model of somatic nociceptive pain where discomfort was initiated using a laser focused on the mouse’s tail, with the time before the mouse flicked its tail away being measured by a sensor. Response groups of 12 mice were analyzed with a control group receiving vehicle alone (i.e., liquid dosing solution without any drug) and other groups receiving either 1mg/kg or 2mg/kg doses of morphine, a common opioid pain relief medication, alone; PNV-5030 alone; or morphine plus PNV-5030.

PNV-5030 alone exhibited a significant pain reduction as compared to the control group and a similar effect to 1mg/kg morphine. Importantly, PNV-5030 demonstrated a significant effect when administered with 1 mg/kg morphine as compared to administering 1 mg/kg morphine alone. Interestingly, when combined with 1 mg/kg morphine, PNV-5030 achieved a similar level of pain reduction to the reduction obtained with 2mg/kg morphine. These results could indicate the possibility of lowering the opioid dose to achieve a similar pain reduction level by combining an opioid with PNV-5030 or even eliminating the use of an opioid for pain relief in favor of a higher dose of PNV-5030.

Notably, certain mice in both the PNV-5030 plus morphine groups achieved results at the maximum time allowed under the study (15 seconds), and, therefore, may have shown even greater pain reduction results had the protocol allowed continuation of the test beyond the time limit. The data are shown in the following chart:

Dr. Julien Dimastromatteo, Purnovate’s Vice President, Research, commented, “We are highly encouraged by what we consider to be robust pre-clinical data demonstrating that PNV-5030 should be advanced as a drug candidate for treating somatic nociceptive pain. We have conducted an additional battery of both in vitro and in vivo screening and believe that PNV-5030 has the characteristics to successfully complete the required toxicity and toxicology studies to allow us to proceed with testing in humans. With our lead compound selection made, we expect to efficiently advance PNV-5030 into clinical trials in 2022.”

William Stilley, Adial’s Chief Executive Officer, stated, “The Purnovate adenosine platform continues to exceed expectations, and PNV-5030’s success in an oral model of pain, after demonstrating pain reduction effects when administered interperitoneally, is a validation of our belief that the platform has the ability to underpin a drug development program addressing pain and a number of other prevalent ailments such as diabetes, asthma, cancer, Parkinson’s Disease, inflammatory bowel disease, and infectious diseases where a cytokine storm is a significant contributing factor, including COVID-19. We are highly encouraged by this data, which suggests PNV-5030 may help reduce the need for morphine and perhaps other opioids when used as either a standalone or combination therapy or eliminate the need for the use of an opioid altogether.”

About Adial Pharmaceuticals, Inc.

Adial Pharmaceuticals is a clinical-stage biopharmaceutical company focused on developing therapies for the treatment and prevention of addiction and related disorders. 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. Additional information is available at www.adialpharma.com.
