New Additions to Leadership Team

The Company added Dr. Gadi Riesenfeld as an independent director to the Company’s Board, replacing Mr. Ron Mayron, a member of the Board since 2021, effective July 6, 2023. Mr. Riesenfeld was the former president of Pharmos Corporation, a publicly traded biotech company listed on NASDAQ, and president of several bio-pharmaceutical companies, including Kamapharm Ltd., Galisar Ltd., and OticPharma.

Research and Development

The Company reported positive imaging results from an internal preclinical study of its investigational drug ExoPTEN, confirming successful nerve regeneration following traumatic full transection of the spinal cord in rats. These results align with previous results showing a remarkable recovery of motor function in 75% of paralyzed rats suffering from spinal cord injuries that were treated with the new therapy. The drug is being developed using NurExone’s proprietary ExoTherapy platform for producing and loading exosomes with pharmaceutical cargo targeting central nervous system injuries.

Furthermore, the Company announced significant advancements in extracellular vesicles (EVs) functionality, leveraging its proprietary and patented 3D-Flow production. These achievements include an amplified immuno-modulatory response, which means the immune system is more capable to respond to injury and achieved a reduction of inflammation activity. In addition, there was significantly improved cellular uptake, allowing NurExone’s EVs to penetrate cells better, holding great promise for the Company’s future EVs-based therapies. The Company is committed to further exploring the potency and therapeutic benefits of EVs produced through the 3D-Flow process using rigorous preclinical and clinical studies.

Overall, these studies underscore the significant potential of the Company’s exosome-based technology and NurExone intends to continue implementing new scientific initiatives to enhance its intellectual properties.

Strategic Collaboration and Partnerships

On June 1, 2023, the Company announced a collaboration with Particle Metrix, a leading provider of particle analysis devices. In connection with the collaboration, a highly-advanced Nanoparticle Tracking Analysis instrument (NTA) has been placed at the Company’s laboratory. The Company plans to leverage the capabilities of the advanced NTA to validate its methodology for analysis of loaded exosomes, a vital part of the development process of its ExoPTEN drug, targeted at the US$2.9 billion global market for patients with acute spinal cord injury.¹

Growth Outlook for 2023

As part of the Company’s strategy to commercialize its exosome-based technology portfolio, enhancing its ExoTherapy production, and scaling its overall business, NurExone intends to implement the following growth initiatives:

• Advance scientific development of NurExone’s ExoPTEN drug and exosome-based technology through preclinical studies;
• Receive written response on the request for a Pre-IND meeting with the U.S. Food and Drug Administration;
• Secure Orphan Drug Designation status for its primary drug product
• Expand intellectual property and file new patent applications with the U.S. Patent and Trademark Office; and
• Establish new strategic collaborations or partnerships looking to unlock business synergies and license NurExone’s exosome platform technology.

Second Quarter Fiscal 2023 Financial Results

• Research and development expenses were US$0.46 million in the second quarter of 2023, compared to US$0.30 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$0.60 million in the second quarter of 2023, compared to US$1.18 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.
• There were no listing expenses incurred in the second quarter of 2023, compared to US$2.04 million in the second quarter of 2022. Listing expenses were recognized, as follows: US$1.61 million at a fair value for the reverse takeover acquisition of 2,536,000 EnerSpar Corp. shares at a share price of CAD $0.80, US$0.24 million for net liabilities of EnerSpar Corp., US$0.19 million for legal costs as associated with the completed reverse takeover transaction in the second quarter of 2022.
• Financial (income) expenses were (US$0.02) million in the second quarter of 2023, compared to US$0.28 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$1.04 million in the second quarter of 2023, compared to a net loss of US$3.80 million in the second quarter of 2022.

As of June 30, 2023, the Company had cash of US$0.88 million (December 31, 2022 – US$2.46 million) and working capital of $0.63 million (December 31, 2022 – $2.11 million). The Company had an accumulated deficit of US$12.16 million as of June 30, 2023, (December 31, 2022 – US$10.42 million).

“We believe our cash position as of June 30, 2023, together with the cash received from the Private Placement, will be sufficient to fund operating expenses and capital expenditure requirements into early 2024”, said Eran Ovadya, CFO of NurExone.
