Curaleaf International to Present Positive Clinical and Pre-Clincial ResearchPosted by On

LONDON–()–Curaleaf International (the “Company”) part of Curaleaf Holdings (CNSX:CURA), Europe’s largest vertically integrated cannabis company, is pleased to announce that Chief Scientific Officer, Dr Barbara Pacchetti will present research on one clinical study and three preclinical studies at a leading conference on medical cannabis on 21-22 October 2022. These papers have been peer-reviewed and selected for presentation and publication in the official Conference Proceedings Journal Medical Cannabis and Cannabinoids (Karger Publishers, Basel, Switzerland).

Research to be presented from the clinical study focuses on the delivery of a cannabidiol (CBD) preparation to patients with Vestibulodynia (VBD) which is a prevalent form of chronic genital pain in women with no standard treatment. The study, a randomized placebo control study, of 60 patients showed significant improvement of outcomes on pain, dyspareunia (genital pain before, during or after sex), pelvic muscular tone and neurometer parameters, which highlights implications for its anti-inflammatory, anti-nociceptive action and anti-neuropathic therapeutic potential. The title of the paper is: Transmucosal delivery of cannabidiol using vestibular electroporation in patients with vestibulodynia: interim analysis of a randomized, blinded prospective trial. The co-authors are F. Murina, Prof. MD., F. Vicariotto, Prof. MD and Barbara Pacchetti, Chief Scientific Officer at Curaleaf International.

Preclinical research to be presented focuses on the potential positive impact of CBD on the treatment of several psychiatric disorders and inflammatory disease, the therapeutic potential for migraine pain and trigeminal excitability related to migraine. For further information on the preclinical research to be presented, please see the footnote at the end of this announcement.*

Dr. Barbara Pacchetti, Chief Scientific Officer at Curaleaf International, commented, “We are very pleased with the findings from our clinical study on the delivery of CBD to treat patients with VBD, and that it is showing a significant improvement in pain outcomes for patients. Additionally, the preclinical research on the therapeutic potential of CBD to treat a number of other indications is also encouraging and I look forward to presenting this to the scientific community and to furthering our research into the potential for CBD. We believe the growth and understanding of medical cannabis must be underpinned by the most robust science. Curaleaf International is working with some of the world’s leading academic institutions such as Imperial College, the University of Milan and University of Insubria and we look forward to further updating all stakeholders with our progress.”

*Details on the preclinical studies

Cannabidiol (CBD) is considered a valuable potential treatment for several psychiatric disorders. This preclinical study demonstrates, for the first time, that CBD is detected in the plasma and medial prefrontal cortex (mPFC), following single or repeated treatment at therapeutical doses, with a specific dose-response profile. CBD significantly modulates brain-derived neurotrophic factor (BDNF) expression, a neurotrophin critical for synaptic plasticity, following a brain specific anatomical pattern. This modulatory effect on BDNF might be functionally relevant and represent added value for the potential therapeutic role of CBD in psychiatric disorders.

Polymorphonuclear leukocytes (PMN) are the first immune cell to be recruited into inflammatory sites, and cannabidiol (CBD) extensively affects their functions. This study confirmed the anti-inflammatory activity of CBD on some PMN functions observed in a previous study. Results indicate that CBD counteracts the effects of priming on key functions such as migration and ROS production, strengthening its therapeutic potential in inflammatory disease.

Clinical and preclinical data have suggested a deregulation of the endocannabinoid system (ECS) in migraine pain and trigeminal excitability related to migraine. This in-vivo study evaluated and found key information on the accumulation of Cannabidiol (CBD) in brain areas that are involved in migraine pain in an animal model at therapeutical doses chronically, and evidenced that a single CBD administration may reduce trigeminal hyperalgesia in an animal model for migraine pain. The results suggested the capability of CBD to modulate migraine-related nociceptive transmission via specific central and peripheral regions.
