NurExone (OTCQB: NRXBF) reported preclinical data showing its lead candidate ExoPTEN produced a reproducible, dose-dependent recovery of visual function in an optic nerve crush (ONC) glaucoma model.
Higher ExoPTEN doses restored scotopic threshold response (STR) amplitudes to levels comparable to uninjured eyes. The study used low (4E+8 particles) and high (4E+9 particles) extrachoroidal doses given twice and measured STR by ERG; responses >5µV were considered detectable.
The company also accelerated expiry of September 2023 and January 2024 warrants, setting a new expiry of 5:00 p.m. (Calgary) on Nov 7, 2025, and noted potential gross proceeds of approximately C$3.2 million if all warrants are exercised. POSITIVE Communications agreement extended to July 10, 2026 with added monthly expense reimbursement.
NurExone Biologic (OTCQB: NRXBF) has announced plans to establish its first U.S. commercial exosome production facility in Indianapolis, Indiana through its subsidiary Exo-Top Inc. The company has secured an incentive offer of up to $255,000 for this expansion.
The planned GMP-compliant facility will serve as Exo-Top's U.S. manufacturing base, producing exosomes for both NurExone's therapeutic pipeline and business-to-business opportunities in regenerative aesthetics. The expansion aligns with Indiana's robust life sciences sector, which generates over $99 billion in annual economic output and has attracted more than $1.5 billion in venture investments since 2019.
This strategic move supports NurExone's progress toward first-in-human clinical trials of ExoPTEN and its plans to uplist to a major U.S. stock exchange.
NurExone Biologic (OTCQB: NRXBF), a biopharmaceutical company focused on exosome-based regenerative therapies, announced several corporate updates. The company received a patent grant in Israel for "Production of Extracellular Vesicles from Stem Cells", complementing their recent U.S. patent allowance.
The company completed a non-brokered private placement raising C$632,655.68 through the issuance of 930,376 units at C$0.68 per unit. Each unit includes one common share and a half warrant exercisable at C$0.88 for 36 months. The proceeds will support preclinical pipeline and U.S. manufacturing initiatives.
Additionally, NurExone announced upcoming presentations at two major U.S. conferences: the 7th Annual Exosome-Based Therapeutic Development Summit and the Bioprocess International Conference in Boston, where company executives will showcase their ExoTherapy technology.
NurExone Biologic (OTCQB: NRXBF) has received a Notice of Allowance from the U.S. Patent and Trademark Office for its proprietary exosome manufacturing process. The patent covers the company's 3D scaffold and shear-stress based bioreactor system for producing stem cell-derived exosomes.
This milestone, combined with the company's GMP-grade Master Cell Bank acquisition in December 2024, strengthens NurExone's supply chain readiness. The technology, developed at the Technion, enables scalable and reproducible exosome production for regenerative therapies. The patent is part of a broader international patent family and is exclusively licensed worldwide to NurExone from the Technion Research and Development Foundation.
NurExone Biologic (OTCQB: NRXBF), a preclinical-stage biotech company developing exosome therapies for central nervous system injuries, reported Q2 2025 financial results and corporate updates. The company raised C$2.3 million through a private placement in April 2025. Key financial metrics show a net loss of US$1.85 million, with R&D expenses of US$0.70 million and G&A expenses of US$1.13 million.

NurExone Biologic (OTCQB: NRXBF) has reported promising preclinical imaging results for its ExoPTEN treatment in spinal cord injury repair. MRI-DTI analysis revealed that ExoPTEN-treated animals showed improved structural integrity and tissue organization in injured spinal cords compared to untreated controls.
The imaging data complements previous functional studies where 100% of animals in a higher-dose group regained motor function. The analysis demonstrated higher Fractional Anisotropy values and lower Mean Diffusivity values near injury sites, indicating better structural preservation.
Additionally, the company has closed a private placement of C$0.78 million, issuing 1,258,072 units at C$0.62 per unit. Each unit includes one common share and a half warrant exercisable at C$0.80 for 36 months.
NurExone Biologic (OTCQB: NRXBF) announced that an independent study by TAmiRNA laboratory revealed their exosomes significantly outperformed commercial industry standards in key healing capabilities. The company's exosomes demonstrated approximately 1.8x higher neurological potential, 2x higher tissue-regeneration and wound-healing signals, and nearly double the anti-inflammatory activity compared to benchmark products.
The analysis, conducted on exosomes produced from NurExone's proprietary master cell bank, validates the company's core technology for therapeutic nerve repair and aesthetic applications. The exosomes will be manufactured by NurExone's U.S. subsidiary, ExoTOP Inc., using their patent-pending 3D production process.

NurExone Biologic (OTCQB: NRXBF) has announced promising preclinical results for its ExoPTEN treatment for spinal cord injury. The study demonstrated that 100% of animals in the high-dose group regained motor function, compared to 50% in the medium-dose group and only 1 out of 6 rats in the control group.
Using the advanced CatWalk XT system for precise measurements, researchers observed significant improvements in multiple walking parameters. High-dose treated animals showed enhanced balance, strength, coordination, and weight bearing during walking, with larger paw print areas, greater maximal contact area, wider base of support, and extended paw contact duration. Importantly, the high dose was well-tolerated with no observed side effects.
The company plans to conduct additional studies exploring alternative dosing regimens while advancing manufacturing process optimization as it prepares for regulatory submissions and first-in-human clinical trials.
