Aiming to promote neural regeneration after spinal cord injury

Aiming to promote neural regeneration after spinal cord injury

Caution: Investigational device. Limited by federal law to investigational use.

Our investigational Neuro-Spinal Scaffold™ is implanted at the site of damage within one week of spinal cord injury with the goal of supporting neural regeneration and cell growth.

If left untreated, a cavity will typically develop at the injury site, cutting off transmission of neural signals from the brain to all body parts below the injury. The scaffold is designed to encourage functional cells to fill in that cavity. If achieved, this structural change within the spinal cord has the potential to improve sensory and motor function and lead to a better quality of life for patients.

Our investigational Neuro-Spinal ScaffoldTM

Our proprietary and investigational Neuro-Spinal Scaffold technology is composed of two biocompatible and bioresorbable polymers which together form a highly porous framework that is conducive to cellular attachment and growth.

The scaffold is surgically implanted into the gap in the spinal column that arises at the site of injury, aiming to create a neuropermissive matrix that allows cells which are critical to neuronal health to respond to the injury site and begin filling the cavity. The scaffold breaks down in the body over several weeks and is resorbed.

How the scaffold is designed to facilitate recovery

If achieved, a robust response can lead to improved outcomes for spinal cord injury patients by:

development of an empty cavity at the injury site

an environment conducive to neural regeneration and tissue remodeling

white matter and allowing for potential remyelination of axons

Visualizing improvement in an animal model

This image shows the effect of the investigational Neuro-Spinal Scaffold implanted after acute spinal cord injury in an animal model.

An empty cavity develops at the site of an untreated injury, cutting off communication from the brain.

Treatment with the scaffold has encouraged tissue remodeling and neuronal growth.

The architecture of the spinal cord has not been restored to pre-injury status. However, the cyst is now filled with a neuropermissive matrix that allows cells, which are critical to neuronal health, to respond to the injury site and begin filling the cavity.

Existing Clinical Results

In its first human clinical study (INSPIRE 1.0), the Neuro-Spinal Scaffold was studied in 19 patients with acute thoracic spinal cord injury.

For more information on our clinical data, please see our corporate deck here.

Clinical trial underway

Based on the INSPIRE 1.0 data, InVivo has initiated the INSPIRE 2.0 clinical study. INSPIRE 2.0 is a 20-patient clinical study designed to assess the potential benefit of the Neuro-Spinal Scaffold in comparison to current standard of care by measuring improvement on the American Spinal Injury Association (ASIA) Impairment Scale (AIS Scale) at six months post-injury.
