DEVON, Pa., March 26, 2018 (GLOBE NEWSWIRE) -- Zynerba Pharmaceuticals, Inc. (NASDAQ:ZYNE), a clinical-stage specialty neuropsychiatric pharmaceutical company dedicated to developing and commercializing innovative pharmaceutically-produced transdermal cannabinoid treatments for rare and near-rare neurological and psychiatric disorders with high unmet medical needs, today announced that researchers at The Scripps Research Institute and the University of Maryland have generated preclinical data from a study funded by NIH grants that suggest potential value in using transdermal cannabidiol (CBD) (ZYN002) to reduce the risk of relapse among recovering drug and alcohol addicts. ZYN002, which was provided by the Company for use in the study, is the first and only pharmaceutically-produced CBD formulated as a patent-protected permeation-enhanced transdermal gel. The results have been published in a paper entitled, ‘Unique Treatment Potential of Cannabidiol for the Prevention of Relapse to Drug Use: Preclinical Proof of Principle’ (Gonzalez-Cuevas, G et al.) in Neuropsychopharmacology, the official publication of the American College of Neuropsychopharmacology (ACNP).
“Remaining drug-free is a constant battle for former substance abusers, and their susceptibility to stress and anxiety can increase their vulnerability for relapse,” said Dr. Friedbert Weiss, investigator for this study and Professor, Department of Neuroscience at The Scripps Research Institute in La Jolla, California. “These preclinical data are interesting as they show that we may be able to use transdermally-delivered CBD to impact multiple dimensions of relapse, namely benefit across a number of vulnerability states and effects that are maintained beyond the brief treatment period. CBD is broadly active and these data provide continued evidence that transdermal CBD may have therapeutic potential in a number of neurological disorders and conditions, including prevention of relapse.”
In summary, according to the authors, the findings in this publication provide proof of principle supporting the potential of transdermal CBD for relapse prevention along two dimensions: beneficial actions across several vulnerability states, and long-lasting effects with only brief treatment.
The publication noted that the clinical potential of CBD when administered orally is constrained to some extent by low bioavailability and potential for conversion into psychoactive cannabinoids in gastric fluid. The authors identified the transdermal route of administration as an effective delivery method that eliminates both of these limitations and produces stable and sustained plasma CBD levels. The researchers utilized a rat model of drug addiction (alcohol, cocaine) and addiction-like behavior to test ZYN002 administered once daily for one week. In this study, ZYN002 reduced relapse provoked by stress and drug cues, and reduced anxiety and impulsivity in the drug-experienced rats without sedative and nonspecific effects on motivation. Five months after therapy ended, treated animals still showed reduced relapse induced by stress or drug cues. According to the authors of the publication, the mechanisms by which CBD impacts these behaviors is not yet understood, but may be related to its ability to modulate the endocannabinoid system or its proneurogenic activity, both of which may explain the long-lasting attenuation of drug seeking and relapse and experimental anxiety.
