CHARLOTTESVILLE, Va., Sept. 26, 2022 (GLOBE NEWSWIRE) -- ADial Pharmaceuticals Inc. (NASDAQ: ADIL; ADILW) (“Adial” or the “Company”), today announced that Purnovate, Inc., a subsidiary of Adial focused on developing novel molecules targeting the adenosine receptors for the treatment of major unmet medical needs, achieved positive in vivo data for PNV-5030, as a potential treatment for chronic pain.
The study was conducted in four groups of ten rats, which underwent surgical injury of the sciatic nerve. After ten days of recovery, mechanical allodynia (measured in grams of pressure) was performed using a 50% withdrawal threshold, an accepted animal model for measuring pain.
Study highlights:
- PNV-5030 treatment was administered orally with a 15mg/kg dose.
- At 30 minutes post dose, PNV-5030 reduced pain by 43% compared to the control group, while acetaminophen (APAP) doses did not have a significant effect (4.7g vs 2.7g, respectively, p<0.05). PNV-5030 also demonstrated a 49% improvement in pain reduction over acetaminophen (APAP-25mg/kg) (4.7g vs 2.4g, respectively, p<0.05).
- At 60 minutes post dose, PNV-5030 reduced pain by 76% compared to the control group (5.3g vs 1.8g, respectively, p<0.05). PNV-5030 also demonstrated a 53% improvement in pain reduction over acetaminophen (APAP-25mg/kg) (5.3g vs 2.4g, respectively, p<0.05).
- At 120 minutes post dose, PNV-5030 reduced pain by 62% compared to the control group, while acetaminophen (APAP) doses did not have a significant effect (4.7g vs 1.8g, respectively, p<0.05).
- At 180 minutes post dose, PNV-5030 reduced pain by 56% compared to the control group (3.4g vs 1.5g, respectively, p<0.05). PNV-5030 also demonstrated a 56% improvement in pain reduction over acetaminophen (APAP-25mg/kg) (3.4g vs 1.5g, respectively, p<0.05).
Dr. Julien Dimastromatteo, Purnovate’s Vice President, Research, commented, “We are encouraged by the results of this study, which demonstrated PNV-5030 reduced pain in an animal model of chronic pain, as compared to both placebo and acetaminophen. This data further reinforces prior in vivo data demonstrating similar outcomes in treating other types of pain. As a result, we look forward to advancing PNV-5030 towards first-in-human clinical trials.”
“PNV-5030 has demonstrated compelling data in animal models of both acute and chronic pain,” said William Stilley, CEO of Purnovate. “Moreover, we believe the success of PNV-5030, Purnovate’s first lead compound, validates our adenosine platform, which has already been used to generate drug candidates that have shown efficacy in pre-clinical models across a wide range of indications, from pain to ulcerative colitis, asthma and even cancer. The broad potential of the platform lends itself well to pursuing potential partnerships and other strategic opportunities.”
PNV-5030 has been tested to be more than 1000-fold selective over the adenosine A1 receptor. Historically, when selectivity has been achieved over the A1 receptor, water solubility has decreased, making biodistribution, which is the ability to achieve 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 and has shown it achieves the necessary biodistribution. Solubility is often an important characteristic of successful drug candidates, and insufficient solubility has historically been a development limitation for adenosine analogues. The solubility profiles of the new compounds under development at Purnovate provide the opportunity to unlock the potential of this class of drugs to treat a broad array of diseases.

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) in heavy drinking patients and was recently investigated in the Company’s ONWARD™ pivotal Phase 3 clinical trial for the potential treatment of AUD in subjects with certain target genotypes (estimated to be approximately one-third of the AUD population) identified using the Company’s proprietary companion diagnostic genetic test. ONWARD showed promising results in reducing heavy drinking in heavy drinking patients, and no overt safety or tolerability concerns. 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.adial.com.
