NurExone Reports First Quarter 2023 Financial Results and Provides Corporate Update

TORONTO and TEL AVIV, Israel, May 24, 2023 (GLOBE NEWSWIRE) -- NurExone Biologic Inc. (the "Company" or "NurExone") (TSXV: NRX) (FSE: J90) (NRX.V), a biopharmaceutical company developing biologically-guided exosome therapy ("ExoTherapy") for patients with traumatic spinal cord injuries, has released its financial results for the quarter ended March 31, 2023.

“The Company is successfully achieving key milestones for our investigational ExoPTEN drug and, in parallel, developing an exosome therapy platform that can be widely used by the medical industry to address many other illnesses,” Dr. Lior Shaltiel, CEO of NurExone. “We believe that the hybrid product-platform model will drive revenue through partnerships, licensing, and commercialization.”

Key Business Highlights

Intellectual Property Portfolio Expansion

On January 12, 2023, the Company received a notice of allowance from the United States Patent and Trademark Office for U.S. Patent Application NO. 17/042,441. The patent that has tuned to a granted Patent in the U.S. on May 16th, covers its cutting-edge Exo-PTEN technology and its drug composition as well as methods for non-invasive intranasal administration of the Company's exosome-based treatment for treating neuronal injury or damage. NurExone currently has a portfolio of intellectual property, which includes the allowed U.S. patent, two Patent Cooperation Treaty (PCT) patent applications that cover the production and composition of matter of our exosomes, and four provisional patents that document loading techniques and siRNA target sequences. As the Company scales, NurExone intends to continue expanding its patent portfolio in order to strengthen its competitive moat.

Promising Pre-Clinical Study Results

On March 20, 2023, the Company disclosed results of an internal pre-clinical study of its proprietary ExoPTEN drug with its proprietary exosome loading technology, which demonstrated effective treatment of 75% of paralyzed rats suffering from spinal cord injuries. These rats regained hind limb reflex, some motor function, and sensory control. The results of the study suggest that ExoPTEN has the potential to generate functional recovery in the central nervous system, which enables NurExone to capitalize on the US$2.9 billion market for acute spinal cord injuriesi.

On February 17, 2023, the Company announced the first interim results of the pre-clinical study of ExoPTEN, that demonstrated significant motor, reflex and sensory improvement in rats following full transection (i.e., complete severing) of the spinal cord. In addition, the Company's pre-clinical loading efficiency study demonstrated that its proprietary loading technology has the potential to serve as an efficient process for loading therapeutic molecular cargo into exosomes, allowing NurExone to establish a cost-effective large-scale exosome production method.

Growth Outlook for 2023

The Company aims to execute the following growth initiatives to advance the Company's strategy of commercializing its ExoPTEN drug product, establishing a platform for ExoTherapy production and expanding its overall business:

  • Submit a Pre-IND meeting request with the U.S. Federal Drug and Administration
  • Obtain Orphan Drug Designation for its flagship drug product
  • File new patent applications with the U.S. Patent and Trademark Office, which cover new siRNA sequences against potential targets for addition neuronal indication in the Central Nervous Nystem (CNS)
  • Enter into new strategic collaborations or partnerships to potentially unlock business synergies and commercialize NurExone's exosome platform technology.

First Quarter Fiscal 2023 Financial Results

  • Research and development expenses were US$0.37 million in the first quarter of 2023, compared to US$0.28 million in the same quarter in 2022. The increase was largely attributable to the research and development efforts towards pre-clinical activity and development of the siRNA- PTEN technology and other siRNA targets.
  • General and administrative expenses were US$0.35 million in the first quarter of 2023, compared to US$1.95 million in the same period in 2022. The decrease was largely attributable to costs relating to the reverse takeover transaction that occurred in Q2 2022.
  • Financial (income) expenses were (US$0.01) million in the first quarter of 2023, compared to US$0.09 million in the same period in 2022. The decrease was largely attributable to costs relating to fundraising in 2022 prior to the reverse takeover transaction, financial derivatives, and exchange rate adjustments.
  • Net loss was US$0.70 million in the first quarter of 2023, compared to a net loss of US$2.31 million in the first quarter of 2022.

As of March 31, 2023, the Company had cash of US$1.59 million (December 31, 2022 - US$2.46 million) and working capital of $1.33 million (December 31, 2022 - $2.11 million). The Company had an accumulated deficit of US$11.12 million as of March 31, 2023, (December 31, 2022 - US$10.42 million).
