  Purpose

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
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, 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 ] [ Designated as safety issue: No ]
  • Adverse event differences between transcranial laser therapy and sham [ Time Frame: Day 90 ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Distribution of scores across the ordinal mRS [ Time Frame: Day 90 ] [ Designated as safety issue: No ]
  • Binary outcome measure of the National Institute of Health Stroke Scale (bNIH) [ Time Frame: Day 90 ] [ Designated as safety issue: No ]

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

Criteria

Inclusion Criteria:
