Last verified: October 2012
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.

Condition Intervention Phase
Acute Ischemic Stroke
Device: NeuroThera® Laser System
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: NeuroThera® Efficacy and Safety Trial - 3 (NEST-3) A Double-blind, Randomized, Sham-controlled, Parallel Group, Multicenter, Pivotal Study to Assess the Safety and Efficacy of Transcranial Laser Therapy With the NeuroThera® Laser System for the Treatment of Acute Ischemic Stroke Within 24 Hours of Stroke Onset

Further study details as provided by PhotoThera, Inc:

Primary Outcome Measures:
  • Disability assessed using the dichotomous modified Rankin Scale (mRS) [ Time Frame: Day 90 ]
  • Adverse event differences between transcranial laser therapy and sham [ Time Frame: Day 90 ]

Secondary Outcome Measures:
  • Distribution of scores across the ordinal mRS [ Time Frame: Day 90 ]
  • Binary outcome measure of the National Institute of Health Stroke Scale (bNIH) [ Time Frame: Day 90 ]

Estimated Enrollment: 1000
Study Start Date: September 2010
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Transcranial Laser Therapy Device: NeuroThera® Laser System
Transcranial delivery of laser therapy or sham (no laser therapy) to the scalp
Sham Comparator: Sham control procedure Device: NeuroThera® Laser System
Transcranial delivery of laser therapy or sham (no laser therapy) to the scalp

  6. Sustained hypotension (SBP <80 mmHg or DBP <50 mmHg)
  7. A presumed and/or confirmed septic embolus
  8. History of CNS vascular disease (e.g. aneurysm, AVM) or history of CNS disease or damage (e.g. neoplasm or dementia) which may influence the subject's outcome assessment.
  9. Head implant of any kind
  10. Significant skin condition of the scalp (eg. psoriasis)
  11. Use of any intravenous or intra-arterial thrombolytic medication
  12. Use of any diagnostic or therapeutic interventional neurovascular procedure
