Adial Pharmaceuticals Issued Second Patent Covering AD04 as a Treatment for Opioid Use Disorder
CHARLOTTESVILLE, VA / ACCESSWIRE / April 15, 2020 / Adial Pharmaceuticals, Inc. (NASDAQ:ADIL; ADILW), a clinical-stage biopharmaceutical company focused on the development of treatments for addiction, today announced that U.S. Patent Number 10,619,209, titled "Serotonin Transporter Gene and Treatment of Opioid-Related Disorders" issued on April 14, 2020. This patent covers the treatment of Opioid Use Disorder by administering the Company's investigational new drug product, AD04, an antagonist of the serotonin-3 receptor (5-HT3), to patients with the LL and TT genotypes, which may be identified by Adial's proprietary genetic test.
The gene responsible for encoding the serotonin transporter (SERT), SLC6A4, located on the chromosome 17q11.1-q12, is the only known gene encoding the serotonin transporter and has a functional polymorphism at the 5'-regulatory promoter region, which results in two forms, long (L) or short (S). The LL-genotype is hypothesized to play a key role in the early onset of alcohol use. The issued patent discloses the differences in treatment and diagnosis based on the LL or SS genotypes as well as on a single nucleotide polymorphism of the SERT gene, the TT genotype of the 3' UTR SNP rs1042173. It relates to the efficacy of using the drug ondansetron (AD04 is ondansetron repurposed at a lower dose than currently approved by the Food and Drug Administration for other indications) based on variations in the polymorphisms of the SERT gene as well as methods for diagnosing susceptibility to abuse of alcohol and other addiction-related diseases and disorders including Opioid Use Disorder.
"This is our second issued patent covering AD04 for the treatment of Opioid Use Disorder," said William Stilley, CEO of Adial Pharmaceuticals. "Importantly, as with the earlier issued patent, the author of this patent is Adial's Chief Medical Officer, Dr. Bankole Johnson. Adial's patent estate around AD04 is robust; we expect market exclusivity for AD04 through 2032, plus potential Hatch-Waxman extensions through 2037. This new patent reaffirms Adial's capacity to address Opioid Use Disorder if efficacy is demonstrated in clinical trials, which we expect to conduct in parallel with advancement of our landmark ONWARD™ Phase 3 pivotal clinical trial for the treatment of Alcohol Use Disorder."
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™ Phase 3 Pivotal 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. www.adialpharma.com
