Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-blind, Placebo-controlled Randomized Evaluation of the Effect of the Erchonia® HLS Laser Device on Children and Adolescents With Autistic Disorder
Actual Study Start Date : July 2, 2017
Actual Primary Completion Date : October 28, 2017
Actual Study Completion Date : November 28, 2017

Arm Intervention/treatment
Experimental: Erchonia HLS Laser
The Erchonia HLS Laser is administered 8 times across 4 weeks for 5 minutes each time to the skull at the base of the brain and temporal areas.
Device: Erchonia HLS Laser
The Erchonia HLS Laser emits a 640 nm (nanometer) wavelength with a tolerance of ±10 nm from each of two 7.5 mw (milliwatt) laser diodes.

Placebo Comparator: Placebo Laser
The Placebo Laser is administered 8 times across 4 weeks for 5 minutes each time to the skull at the base of the brain and temporal areas.
Device: Placebo Laser
The Placebo Laser emit the same visible light output as the active HLS Laser but without therapeutic effect.

Primary Outcome Measures :
  1. Mean Change From Baseline to Study Endpoint in the Aberrant Behavior Checklist (ABC) Irritability & Agitation Subscale Score. [ Time Frame: Baseline and 4 weeks (Study Endpoint) ]
    Primary outcome measure in this study is defined as the mean change from baseline to 4 weeks of intervention (study endpoint), in the Aberrant Behavior Checklist (ABC) Irritability Subscale score. The ABC Irritability Subscale contains 15 items relating to aggression, self-injury, tantrums, agitation and unstable mood in individuals with developmental disorders. Each item is rated from 0 (not at all a problem) to 3 (the problem is severe in degree). The individual scores are summed for a total score from 0 to 45, with higher scores indicating greater severity. A negative (-) change indicates a decrease in symptom severity and is positive for improvement. A positive (+) change indicates an increase in symptom severity and is negative for improvement. Study success is established as the detection of a minimum mean difference of -8.5 points between test and placebo groups in the change in ABC Irritability Subscale score.
