First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tests whether a single dose of CRIS100 is safe for people with a recent spinal cord injury in the upper back. Only 5 adults with severe injuries will receive the drug directly at the injury site within 72 hours. The study focuses on side effects and lab changes, not on curing the injury.
