Firm’s evaluation signifies the profitable achievement of its proprietary loading expertise for producing exosome-based therapies
Calgary, Alberta–(Newsfile Corp. – November 30, 2022) – NurExone Biologic Inc. (TSXV: NRX) (FSE: J90) (the “Firm” or “NurExone”), a biopharmaceutical firm growing biologically-guided exosome remedy (“ExoTherapy”) for sufferers with traumatic spinal cord accidents, reported at present outcomes of a pre-clinical loading effectivity research that was accomplished by the Firm displaying that its progressive and proprietary loading expertise has the potential to function an environment friendly course of for loading of therapeutic molecular cargo into exosomes. In exosome-based therapies, loaded exosomes are biologically guided to focus on infected tissues to “dock” and unload their therapeutic cargo, making a therapeutic atmosphere.
The Firm’s platform for exosome-based remedy manufacturing is deliberate to incorporate: (i) a large-scale exosome manufacturing, (ii) a therapeutic cargo and (iii) a novel expertise to load the therapeutic cargo. Earlier scientific analysis outcomes and initiatives have demonstrated the effectivity of the Firm’s large-scale exosome manufacturing course of and the effectiveness of the Firm’s proprietary small-interfering RNA (“siRNA”) sequences as a therapeutic cargo. This latest research analyzes the Firm’s expertise for loading therapeutic cargo into exosomes.
The research outcomes indicated that NurExone’s proprietary loading expertise achieved the specified loading effectivity with out compromising the performance of the loaded molecular cargo. Determine 1 reveals a visible inspection of utilizing gold-standard hydrophobic loading moiety because the optimistic management group versus NurExone’s loading expertise, which makes use of a proprietary hydrophilic moiety linked to its molecular cargo. Determine 2 demonstrates the loading share equivalency, measured by co-localization of the exosome and its therapeutic cargo, which is an ordinary metric, permitting the corporate to have its personal proprietary patent-pending expertise. Performance was additionally assessed by measuring PTEN inhibition of the siRNA cargo after loading into the exosomes as highlighted in Determine 3. Inhibition of the protein PTEN promotes axon regeneration and neural restore[1], key parts for regeneration of neurons after a traumatic spinal cord injury.
NurExone intends to monetize its proprietary expertise platform and can discover potential licensing alternatives for this loading method as soon as it’s finalized.
Dr. Lior Shaltiel, CEO of NurExone, commented, “Realizing the promise of exosome-based therapies requires environment friendly expertise for loading therapeutic molecules into the exosome nanocarriers. We imagine that our progressive and unique loading expertise overcomes this trade hurdle, which allows us to capitalize on potential expertise platform licensing alternatives and the commercialization of our ExoTherapy merchandise produced thereby.”
For the potential remedy of sufferers with traumatic spinal cord injury sufferers, NurExone intends to make use of its ExoTherapy’s proprietary exosomes as biologically-guided nanocarriers to ship specialised siRNA therapeutic compounds to focus on areas. The delivered molecules promote an atmosphere that induces a therapeutic course of on the goal location.

The research used EVs (exosomes) remoted from bone marrow-derived Mesenchymal Stem Cells MSCs (violet) loaded with Cy3-labeled siRNA (inexperienced) for each processes. The siRNA-loaded exosomes are noticed utilizing super-resolution microscopy (Mild Sheet, Zeiss Z7). Evaluation of colocalization (white) reveals ~60% loading effectivity with the NurExone loading course of, much like the outcomes achieved by the management group.

The above determine compares the loading share of conjugated si-PTEN utilizing NurExone’s proprietary expertise in comparison with a management. NurExone’s expertise achieves 62.3% loading effectivity, displaying substantial equivalence to the management course of (59.5%).

The graph above signifies that NurExone’s proprietary loading moiety conjugated to siRNA doesn’t have an effect on the effectivity of NUR001 siRNA to knock down PTEN expression (RNA) following transfection in HEK293 cells. There isn’t any statistical distinction between the processes – NUR001, NUR001 + hydrophobic loading moiety as commonplace and NUR001 +NureExo-Load (proprietary loading expertise) by way of PTEN inhibition in HEK293 cells
