Avicanna Files US Patent Application for a Novel Cannabinoid Formulation in Reducing Incidence of Seizures and Sudden Unexpected Death in Epilepsy

• Research findings originated from cannabinoid-based collaboration with leading epilepsy researcher, Dr. Peter Carlen, at UHN that is also supported by a Mitacs Accelerate program grant.
  
• Avicanna's proprietary formulation showed promising pre-clinical results in reducing seizures and will be developed through the company's pharmaceutical development pipeline as an epilepsy drug candidate.

Avicanna Inc. (" Avicanna " or the " Company ") (TSX: AVCN) (OTCQX: AVCNF) (FSE: 0NN) a biopharmaceutical company focused on the development, manufacturing and commercialization of plant-derived cannabinoid-based pharmaceuticals is pleased to announce that it has filed a provisional patent application with the United States Patent and Trademark Office, entitled "Methods for Reducing or Eliminating Incidence of Seizures and Sudden Unexpected Death in Epilepsy", on the use of a novel cannabinoid formulation (the " Formulation Candidate ").

The research findings originated from the ongoing multi-level cannabinoid-based collaboration with leading epilepsy researcher Dr. Peter Carlen at the world-renowned Krembil Research Institute at the University Health Network ("UHN"). Preliminary electrophysiological studies on seizure induced wildtype mouse cortical slices determined that treatment with the Formulation Candidate produced significant anti-convulsant effects as compared to treatment with cannabidiol ("CBD") or tetrahydrocannabinol ("THC") alone. These results, obtained in a well-established in vitro model, suggest that, in addition to anti-convulsant properties, the Formulation Candidate demonstrates strong potential to treat patients diagnosed with intractable forms of epilepsies and at risk of seizure-induced Sudden Unexpected Death in Epilepsy ("SUDEP"). Further studies on the mechanism of action of the cannabinoids in the Formulation Candidate confirmed that the cannabinoids acted as selective 5-HT1A receptor agonists similar to established 5-HT1A receptor agonists in seizure-like events.

Aras Azadian, Chief Executive Officer of Avicanna, stated: "Understanding the anti-convulsant properties of our proprietary formulation in seizure disorders is important particularly since this combination drug has potential to reduce the likelihood of seizure-induced sudden death in epilepsy. The exceptional research conducted by Dr. Carlen's team with support from our R&D team, and the resulting patent submission will be a major driver for guiding our long-term drug and clinical development plans, particularly since its in the area with an existing FDA approved cannabinoid-based drug."

Avicanna intends to conduct in vivo studies in the coming months in order to formalize this provisional application. If granted, this patent application will provide Avicanna with protection on the use of the Formulation Candidate within a specified ratio of cannabinoids, alone or in combination with other anti-epileptic agents.
