Efficacy and Safety Trial of Transcranial Laser Therapy Within 24 Hours From Stroke Onset (NEST-3) "NEST-3"


Phase 3 Results N/A

Trial Description

The purpose of this pivotal study is to demonstrate safety and efficacy of transcranial laser therapy (TLT) with the NeuroThera® Laser System in the treatment of subjects diagnosed with acute ischemic stroke. The initiation of the TLT procedure must be feasible for each subject between 4.5 and 24 hours of stroke onset.
