NurExone Biologic Receives FDA Orphan-Drug Designation, Accelerating Development of ExoPTEN therapy for Acute Spinal Cord Injury Treatment

TORONTO and HAIFA, Israel, Oct. 30, 2023 (GLOBE NEWSWIRE) -- NurExone Biologic Inc. (TSXV: NRX) (FSE: J90) (NRX.V) (the “Company” or “NurExone”), a pioneering biotechnology company, is thrilled to announce that the U.S. Food and Drug Administration (FDA) has granted Orphan-Drug Designation (ODD) for its ExoPTEN therapy, recognizing the potential of this groundbreaking regenerative therapy for acute spinal cord injury, a condition where effective treatments are limitedi.

The orphan drug designation provides significant benefits to pharmaceutical companies developing drugs for rare diseases, i.e. those impacting fewer than 200,000 people in the United Statesii. These benefits include market exclusivity, financial incentives, regulatory assistance, and support with drug development. Overall, the designation incentivizes and supports the development of certain treatments, increasing access to therapies for patients.

Earning orphan-drug designation is a significant milestone for the Company. The designation covers the use of mesenchymal stem cell (MSC) derived small extracellular vesicles (EVs) loaded with short and modified interfering RNA (siRNA) targeting the phosphatase and tensin homolog (PTEN) protein for acute spinal cord injury, as implemented in the Company’s ExoPTEN drug under development.

“Orphan-drug designation is expected to streamline our go-to-market, shorten our regulatory process saving the Company millions of dollars, and provide valuable market exclusivity. We appreciate the formal recognition of the potential impact of our therapy on the lives of patients suffering from acute spinal cord injuries,” said Dr. Shaltiel, CEO of NurExone Biologic, Ltd.
