What this trial studies

The PRIME Study is an early feasibility assessment aimed at evaluating the safety and functionality of the Neuralink N1 Implant and R1 Robot in individuals suffering from severe quadriplegia or tetraparesis due to spinal cord injury or ALS. This innovative approach involves a wireless, rechargeable implant that connects to electrode threads inserted into the brain by a robotic device. The study seeks to determine how effectively this technology can restore communication and control for patients with significant motor impairments.

Who should consider this trial

Good fit: Ideal candidates are individuals with severe quadriplegia or tetraparesis due to spinal cord injury or ALS, who have had no improvement for at least one year.

Not a fit: Patients with moderate to high risk for serious perioperative adverse events or those with active implanted devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this technology could significantly enhance the quality of life for patients with severe paralysis by enabling them to control devices and communicate more effectively.

How similar studies have performed: While this approach is novel, similar studies involving brain-computer interfaces have shown promise in preliminary phases.

* Ability to communicate in English
* Presence of a stable caregiver

Exclusion Criteria

* Requires magnetic resonance imaging (MRI) for any ongoing medical conditions
* Acquired or hereditary immunosuppression
* Use of smoking tobacco or other tobacco products
* Psychiatric or psychological disorder
* Brain MRI demonstrating hemorrhage, tumor, distorted or adverse anatomy.
