Griffith University – Human Clinical Trial Update – September 2026

An important update on the human clinical trial.

Perry Cross recently visited Professor James St John and the Spinal Injury Project team at Griffith University to discuss the latest progress on the world-first Nerve Bridge Transplantation and Rehabilitation Human Clinical Trial.

In this video, Perry and Professor St John provide a transparent update on the delays the team has been working through, the progress being made and the important steps ahead.

This Phase I study will combine participants’ own specialised olfactory cells—formed into cellular nerve bridges—with intensive rehabilitation for people with chronic spinal cord injury.

There is encouraging news: the team is approaching completion of the final cell-manufacturing requirements. One final engineering run is needed to test the entire manufacturing process under strict human-grade standards. Once this process has been successfully completed and approved, the team will be ready to proceed with the first two participants.

The initial trial will primarily assess the safety and feasibility of transplanting cellular nerve bridges into people with chronic spinal cord injury. It represents the culmination of more than a decade of research and builds on the pioneering work of the late Professor Alan MacKay-Sim.
Watch the video to hear directly from Perry and Professor St John about the progress being made towards our shared vision: translating this extraordinary research into a potential treatment for spinal cord injury.
