# Clinical Data

BACKGROUND: The purpose of this clinical study was to determine the effectiveness of the Erchonia® EVRL, manufactured by Erchonia Corporation (the Company), when both the red and violet diodes are activated simultaneously, in providing temporary relief of minor chronic neck and shoulder pain of musculoskeletal origin.

STUDY DESIGN: The study was a single (active treatment only) group non-inferiority design to evaluate equivalency or superiority of the Erchonia® EVRL in red/violet diode combination application with red diode only application in the temporary reduction of neck and shoulder pain of musculoskeletal origin. The comparative active data for the Erchonia® EVRL red diode only therapy was attained in the 2001 trial whose results successfully supported 510(k) clearance (K050672) of application of the EVRL in red diode mode only for the identical indication being sought through the results of this clinical trial.

SUBJECTS: Forty-four (44) subjects completed the study. Subjects were predominantly Caucasian (82%) males (39%) and females (61%) of average age 54.07 years with chronic neck and/or shoulder pain of musculoskeletal origin: osteoarthritis, chronic muscle spasms or cervical and thoracic spine sprain strain who rated 50 or greater on the 0 to 100 Visual Analog Pain Scale (VAS). Average subject duration of neck and shoulder pain was 76.58 months with the location of pain quite evenly distributed across the right and left sides. Average VAS pain rating at study entry was 65.00. In the 2001 comparative trial, 43 subjects received the active Erchonia® EVRL red diode only procedure administration.

STUDY PROCEDURES: Each subject received a single 13-minute active procedure administration with the Erchonia® EVRL at the investigator's test site as in the 2001 trial, differing only in dual-diode (red and violet) versus single-diode (red only) application, respectively.

STUDY RESULTS: Study primary outcome measure was change in Visual Analog Scale (VAS) neck and shoulder pain rating from baseline to study endpoint evaluation. Individual subject success criteria was established as a 30% or greater decrease in VAS rating at endpoint relative to baseline. The study was pre-established as a non-inferiority study (equivalency or superiority) of the EVRL in red/violet diode combination therapy compared to the red diode only therapy as based upon the comparative data from the 2001 trial. Overall study success criteria was established as 65±5% of individual subject successes in the current trial.

Seventy-five per cent (75%) of subjects in this study attained individual subject success compared with 65.1% of actively treated subjects in the 2001 trial, exceeding the overall study success criteria by 5%.

The 29.80-point mean decrease (from 65.00 to 35.20) in neck and shoulder VAS pain rating from study Baseline to Endpoint for subjects in the Current study is comparable to (slightly above) the respective 29.02-point mean decrease (from 60.21 to 31.19) for 2001 Active study subjects.

{8}------------------------------------------------

T-test for correlated samples found the 29.80-point mean decrease for Current study subjects to be statistically significant at p<0.0001.

Image /page/8/Figure/1 description: The image is a line graph comparing the mean neck and shoulder pain VAS ratings from baseline to endpoint evaluation for both the current and 2001 active groups. The x-axis represents the evaluation period (Baseline, Endpoint, 24 Hours Post, 48 Hours Post), and the y-axis represents the pain VAS ratings from 20 to 70. The graph shows that both groups experienced a statistically significant decrease in pain ratings from baseline to endpoint, which was maintained across the subsequent 48-hour evaluation period.

Image /page/8/Figure/2 description: The image shows the title of a chart. The title is "Chart 1: Mean neck and shoulder pain VAS ratings across study duration". The title is written in a clear, sans-serif font and is centered on the image.

The secondary measure of change in neck and shoulder range of motion (ROM) demonstrated sizable improvements. Mean shoulder ROM in Seated Passive Abduction improved 27.95 degrees on each of the right and left sides. Mean shoulder ROM measurements in relaxed position improved 30.11 degrees on the right side and 28.52 degrees on the left side. Mean neck ROM measurements improved 22.68 and 23.36 degrees for the right and left sides, respectively.

At completion of the procedure administration (endpoint) and again at 24- and 48-hours postprocedure, subjects were asked to rate satisfaction with any perceived overall change in neck and shoulder pain on a 5-point scale. Subjects who were 'Very Satisfied' with the study procedure increased from 41% at endpoint evaluation to 46% at 48 hours post-procedure evaluation. Seventyone per cent (71%) of subjects remained 'Satisfied' ('Very Satisfied' or 'Somewhat Satisfied') across the 48 hours post-procedure evaluation period.

ADVERSE EVENTS: No adverse event occurred for any subject throughout study duration.

period.

SUMMARY: These study results demonstrate that the Erchonia® EVRL in dual red/violet diode application is as effective in reducing neck and shoulder pain of musculoskeletal origin as the Erchonia® EVRL in red diode only mode.

{9}------------------------------------------------

## Conclusion

Any differences between the subject device and predicate do not render the device not

substantially equivalent, do not affect safety or effectiveness, or raise different questions of safety and effectiveness despite the fact that total light energy delivered per treatment is marginally greater to the predicate. The new and predicate device has identical technology and provides the same outputs. The predicate device treatment protocol went through a clinical trial to demonstrate that it is effective in providing relief of chronic neck and shoulder pain.
