Patent No. US 11,998,632 B2 (“Patent”) covers Avicanna’s self-emulsifying drug delivery system (“SEDDS”) oral cannabinoid composition and methods of treating neuropathic pain

TORONTO, June 19, 2024 (GLOBE NEWSWIRE) — Avicanna Inc. (“Avicanna” or “Company”) (TSX: AVCN) (OTCQX: AVCNF) (FSE: 0NN), a biopharmaceutical company focused on the development, manufacturing, and commercialization of plant-derived cannabinoid-based products, is pleased to announce the United States Patent and Trademark Office (“USPTO”) issuance of the Patent covering Avicanna’s SEDDS oral cannabinoid compositions and methods for treating neuropathic pain.

“We are delighted to announce the USPTO’s issuance of the Patent covering our SEDDS drug delivery technology. Research, development, and evaluation of the potential role of cannabinoids in advanced drug delivery systems for therapeutic benefit have been at the core of the Company’s mission since inception. We are appreciative of the work done by our scientists that have brought us to this milestone, and we are excited about the possibilities of further clinical applications for cannabinoid treatments in neuropathic pain and working closely with healthcare providers to support patients in need,” stated Aras Azadian, CEO.

About the SEDDS Technology

Due to the highly lipophilic nature and poor water-solubility of cannabinoids, the formulations currently available in the Canadian market have been generally described as having poor absorption and high variability of onset. SEDDS oral delivery systems offer a route for non-invasive and non-inhalation administration of cannabinoids.1-4 

Avicanna’s SEDDS technology demonstrated shelf-life stability with more than 90% of the total cannabinoid(s) remaining after 6 months in accelerated conditions. CBD and THC dissolution profiles were also tested in biorelevant media which mimic human intestinal fluid and demonstrated more than 90% dispersion within one hour with continued stabilization of the emulsion.
