Pre-clinical &
Clinical Testing
- Completed healthy human subjects trial establishing safety, tolerability, and dose response.
- Clinical data in cerebral vasospasm patients showed a reduction of death-and-disability rates from 50% to 0% in a six-subject study when used to reverse vasospasm in the Neuro-ICU.
- 10 peer-reviewed scientific papers published to date.


Increase in brain perfusion index after one stimulation in blue; and after two stimulations 120 minutes apart in red.
