Since 1986, Woerly has transitioned from working with natural polymers like collagen to synthetic hydrogels due to their inert nature and reduced immune response as well as the possibility of adjusting their physico-chemical properties and adding novel functionalities to the polymer network targeting neuronal biological functions. His fellowship with the Medical Research Council of Canada and studies at the Institute of Macromolecular Chemistry in Prague refined his skills in hydrogel design. Upon returning to Canada, Woerly advanced hydrogel systems with improved physical properties and geometry, reinforcing his role as a pioneer in neurorestorative science.

Revolutionizing Spinal Cord Regeneration

Woerly has concentrated on a critical challenge: tuning the physical and chemical properties of hydrogels to match the nervous system’s biology for effective regeneration. His innovative approach focuses on axonal regeneration, angiogenesis, and the recruitment of endogenous stem cells to heal volumetric tissue defects. NeuroBioMat’s hydrogel acts as an extracellular matrix, promoting the self-healing ability of the spinal cord and supporting long-term repair as it enables tissue remodeling. The key challenge is to restore the translesional spinal network and connectivity across the lesion. With extensive preclinical experience, Woerly’s team has developed a hydrogel suitable for human applications, set for its first trials in 2025.

Given its patient-targeted specificity, NeuroBioMat’s technology has received FDA Breakthrough Device Designation in 2022.

Woerly’s expertise merges polymer chemistry with nervous system regeneration, providing a unique tissue engineering solution. Unlike temporary relief methods like neurostimulation and exoskeletons, Woerly’s approach aims for permanent regeneration of both motor and sensory systems, as the most promising way to promote functional recovery in people with spinal cord injuries. While only two companies, NeuroBioMat and InVivo Therapeutics, are pursuing this type of solution, NeuroBioMat’s non-degradable hydrogel stands out as a semi-solid system with a dynamic structure that allows it to adapt to cell dynamics during tissue repair. It supports longer-term tissue remodeling, essential for the lengthy spinal cord regeneration process, unlike rapidly absorbed biodegradable hydrogels. NeuroBioMat’s hydrogel exhibits sufficient physicochemical and structural properties to support neuronal tissue regeneration.

Progress in Preclinical Trials

While the first human study is slated for 2025, the success stories to date come from extensive preclinical trials using spinal cord injury models in animals. These trials have involved both transection and compression models, which mimic human spinal cord injuries. Woerly highlighted a series of experiments conducted in Canada and the U.S., where NeuroBioMat’s hydrogel was implanted into the spinal cords of animals. 

These experiments, performed in collaboration with academic institutions like UCLA, the University of Kentucky, and the University of Alabama, showed promising results. Using techniques such as immunocytochemistry and behavioral studies, researchers observed significant regeneration of nerve fibers within the hydrogel. Additionally, the trials showed mobilization of endogenous stem cells, microvascularization, and partial recovery of locomotor functions.

Though not 100% recovery was achieved, Woerly emphasized that even a 10% regeneration of motor system axons could lead to significant improvements in patients’ quality of life. The potential to restore minimal motor functions offers hope to individuals suffering from spinal cord injuries, whose lives are often marked by chronic pain and limited mobility. 

The success of these preclinical trials, conducted over several years, has laid the foundation for human trials. NeuroBioMat is actively working with the FDA to prepare for the first-in-human study, which represents the next critical step toward bringing this neurorestorative technology to patients.

One key factor in the prioritization of this research is the simplicity of the hydrogel application. Neurosurgeons prefer straightforward technologies, particularly in operating rooms where time and ease of use are critical. NeuroBioMat’s hydrogel, designed specifically for spinal cord injuries, offers several attractive properties for surgeons. The gel, known as SPINEREP is bioadhesive, meaning it sticks immediately to neural tissue without the need for sutures. Additionally, it has hemostatic properties, helping to stop microbleeding, a common challenge in spinal cord surgeries, and maintaining a clear operating field. Furthermore, the polymer scaffold has elasticity and mechanical strength properties similar to the neural parenchyma, facilitating its surgical implantation and integration into spinal tissue. 

Woerly’s focus on hydrogel technology stems from its ease of use and effectiveness. SPINEREP can be easily cut to fit the lesion cavity and, once applied, stays in place to help reconstitute the anatomical continuity of the spinal cord. While the current focus is on spinal cord injuries, Woerly noted that future research could extend this technology to brain injuries, requiring further study to explore its potential in reconstructing parts of the brain using hydrogel systems.

Future of NeuroRestorative Biotechnology

Woerly envisions significant advancements in neurorestorative biotechnology, particularly in the realm of hydrogel technologies by modifying the chemical structure of polymer networks to give them specific properties or enhance their performance. Thus, he sees the future focusing on chemically attaching growth factors, such as BDNF (Brain-Derived Neurotrophic Factor), to hydrogels to enhance their biocompatibility/biofunctionality couple within the nervous system. This approach could accelerate tissue regeneration and improve outcomes for patients suffering from neurological injuries.

Additionally, Woerly foresees the potential for combining hydrogels with stem cells to address volumetric tissue defects in the brain. This combination could prepare new tissue that could be transplanted into the brain or spinal cord, further expanding the capabilities of neurorestorative technology.
