TORONTO and HAIFA, Israel, June 11, 2024 (GLOBE NEWSWIRE) -- NurExone Biologic Inc. (TSXV: NRX), (OTCQB: NRXBF), (Germany: J90) (the "Company" or "NurExone"), a pioneering biopharmaceutical company developing regenerative medicine therapies, is pleased to announce that the Japan Patent Office recently issued a Notice of Allowance for an ExoPTEN patent, covering innovative Extracellular Vesicles (EVs) comprising a phosphatase and tensin homolog ("PTEN") inhibitor and their application use. The Company's ExoPTEN drug, currently under development, aims to promote nerve growth and regeneration after acute spinal cord injury by inhibiting the PTEN protein.

The patent, titled "Vesicles Comprising a PTEN Inhibitor and Uses of Same", was originally submitted by the Technion Research and Development Foundation Ltd. ("Technion") and Ramot at Tel Aviv University Ltd. It is the first patent licensed by NurExone from Technion and describes a fundamental element of the Company's ExoPTEN nanodrug under development for acute spinal cord injury.

Dr. Bat-Ami Gotliv, Patent Attorney for NurExone, stated, "The allowance of this patent application in Japan safeguards NurExone's technology in a vital Asian market. This approval, alongside the corresponding patents granted in the United States of America and Russia, underscores the novelty and inventive step of NurExone's technology."

Dr. Lior Shaltiel, CEO of NurExone, explained, "This patent, which belongs to the ExoPTEN family in our extensive IP portfolio, is included in the exclusive worldwide licensing from the Technion. We are making progress using ExoPTEN, our first nanodrug, and other newly developed technologies as we move towards clinical trials in humans and commercialization."

Mr. Yoram Drucker, Co-Founder, Chairman and VP Strategic Development, elaborated, "We see Japan as an important territory for our products and technology. This expands our potential market to the Far East, and if we succeed in showing benefits in other Central Nerve System indications, we may dramatically increase our market potential."

A Notice of Allowance represents the final stage prior to the grant, pending the Company's payment of the registration fees.
