  • Company continues to expand its patent estate for EP-104IAR with patent grant in Israel

VICTORIA, BC, Sept. 16, 2021 /CNW/ - Eupraxia Pharmaceuticals Inc. ("Eupraxia" or the "Company") (TSX: EPRX), a clinical-stage biotechnology company with an innovative drug delivery platform technology, today announced an update for its lead osteoarthritis (OA) drug candidate EP-104IAR.

Publication in Osteoarthritis and Cartilage Open

Eupraxia today announced the publication of its Phase 1 EP-104IAR results in Osteoarthritis and Cartilage Open. The article, entitled, "Safety and Pharmacokinetics of EP-104IAR (sustained-release fluticasone propionate) in Knee Osteoarthritis: A Randomized, Double-Blind, Placebo-Controlled Phase 1 Trial", is available to all readers through the medical journal's website at:

"Publication in this highly regarded, peer-reviewed journal will provide a larger group of specialists and practitioners with early insight into the safety and efficacy of EP-104IAR as a potential long-acting treatment for knee OA pain," said Amanda Malone, Chief Scientific Officer of Eupraxia and lead author of the article. "We believe these data are significant in light of the medical community's current debate regarding the safety and short duration of action of existing immediate-release corticosteroids, which points toward the unmet medical need for a safer, long-acting therapeutic."

The Phase 1 data indicate that a 15 mg dose of EP-104IAR is well-tolerated, with few local or systemic adverse findings, and no signs of adrenal suppression. While the Phase 1 clinical trial was not powered to detect treatment differences, analyses of all the efficacy measures illustrate that EP-104IAR provided immediate, and substantial pain relief (similar to other intra-articular steroids) with distinct numerical separation from placebo for between eight and 12 weeks.

The Phase 1 data supported the Company's progression to its 300-patient Phase 2 trial that is currently screening patients at three sites in Denmark. Patients will be randomised to receive a single injection of 25 mg EP-104IAR or placebo, and have their pain relief measured out to a maximum of six months.

More information on the Company's Phase 2 trial is available here:

Intellectual Property Update

The Company announced today that it received a Notice of Allowance from the Israel Patent Office with respect to its patent application Injectable Sustained Release Composition and Method of using the Same for Treating Inflammation in Joints and Pain Associated Therewith.

The Company believes that the patent allowance further strengthens its intellectual property platform for EP-104IAR (the "Patent Allowance").

About EP-104IAR

Eupraxia's lead product candidate, EP-104IAR, is designed to meet the significant unmet medical need and market demand for long-lasting pain relief for knee OA. The U.S. Centers for Disease Control and Prevention estimates that knee OA affects more than 30 million people in the U.S. alone. This includes 14 million that suffer with knee pain or some form of disability. Knee OA is also associated with depression and loss of sleep, which can greatly affect quality of life.

With EP-104IAR, Eupraxia hopes to change the way knee OA pain is treated. Current therapies are challenged by poor safety, inadequate efficacy and/or limited duration of activity. Corticosteroids are one of only two drug classes strongly recommended by the American College of Rheumatology and the Arthritis Foundation for the treatment of knee OA pain. Currently approved corticosteroids are very effective at reducing pain for a short duration but can expose the body to unwanted local and systemic side effects.

EP-104IAR is being developed to provide long-term pain relief with fewer unwanted side effects. It encapsulates a highly potent corticosteroid (fluticasone propionate) within a microns-thin polymer membrane.

Injected into the knee, EP-104IAR is intended to slowly release drug at therapeutic concentrations for up to six months. This has the potential dual advantage of providing long-duration pain relief with fewer systemic side effects. An enhanced safety profile would also benefit the estimated 70% of knee OA patients that experience pain in both knees.

EP-104IAR has completed a Phase 1 trial and is currently in Phase 2 clinical development. A modified version of EP-104IAR is under development for canine and equine OA.

About Eupraxia

Eupraxia is a clinical-stage biotechnology company focused on the development of locally delivered, extended-release alternatives to currently approved drugs. Each of Eupraxia's product candidates has the potential to address therapeutic areas with high unmet medical need and strives to provide improved patient benefit by delivering targeted, long-lasting activity with fewer side effects.

Eupraxia's lead product candidate, EP-104IAR, is currently in Phase 2 development for the treatment of pain due to OA of the knee. In addition to EP-104IAR, Eupraxia is developing a pipeline of earlier-stage long-acting formulations. Potential pipeline candidates include a range of drugs for indications such as post-surgical pain (EP-105), and post-surgical site infections (EP-201), each designed to improve on the activity and tolerability of approved drugs. Eupraxia is also developing a formulation of EP-104IAR for use in canine and equine OA.
