## Performance Testing-Clinical

## Clinical Data

BACKGROUND: The purpose of this clinical study was to determine the effectiveness of the Erchonia® GVL, manufactured by Erchonia Corporation (the Company), when both the green 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 group non-inferiority design to evaluate equivalency or superiority of the Erchonia® GVL when applied in simultaneous green / violet dual diode mode to that of application of the Erchonia® EVRL when applied in simultaneous red / violet dual diode mode. The comparative data for the Erchonia® EVRL red / violet laser device was attained in the 2019 trial whose results successfully supported 510(k) clearance (K191257).

SUBJECTS: Forty-three (43) subjects completed the study.

STUDY PROCEDURES: Each subject received a single 13-minute active procedure administration with the Erchonia® GVL at the investigator's test site identical to the 2019 Erchonia® EVRL trial.

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 pre-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 of the Erchonia® GVL laser compared to the Erchonia® EVRL laser comparative data from the 2019 trial. Overall study success criteria was established as 75±5% of individual subject successes in the current trial.

Eighty-one-point four per cent (81.4%) of subjects in this study attained individual subject success compared with 75.0% of subjects treated in the 2019 Erchonia® EVRL trial.

The 37.77-point mean decrease (from 71.79 to 34.02) in neck and shoulder VAS pain rating from study Baseline to Endpoint for subjects in the current GVL study is comparable to the respective 29.80-point mean decrease for subjects in the 2019 EVRL study. T-test for correlated samples found the 37.77-point mean decrease for GVL study subjects to be statistically significant at p<0.0001.

Image /page/7/Figure/9 description: The image is a line graph titled "VAS Ratings Across Study Duration: GVL vs. EVRL". The x-axis represents the study duration, with labels for "Pre-Procedure", "Endpoint", "24 Hours Post", and "48 Hours Post". The y-axis represents the VAS ratings, ranging from 20 to 80. The graph compares the VAS ratings for GVL and EVRL over the study duration, with both lines showing a decrease in ratings over time.

Image /page/7/Figure/10 description: The image shows the title of a chart. The title is "Chart 1: Mean low back pain VAS ratings across study duration". The chart likely shows the mean low back pain VAS ratings over the course of a study.

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

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

## Substantially Equivalent Discussion

The Erchonia® GVL is substantially equivalent to the predicate device, the Erchonia® EVRL previously submitted under K191257. Both the subject device and the predicate device have identical principles of operation, power, energy source, energy delivery, mechanism of action, and treatment times. The only technological difference between the subject and the predicate device is the substitution of a red laser diode with a green laser diode of identical power, while the second diode consistently emits a violet wavelength in both devices. This difference does not render the device not substantially equivalent, does not affect the safety or effectiveness, or raise different questions of safety and effectiveness. Erchonia Corporation maintains extensive clinical data establishing safety and effectiveness for "providing temporary relief of minor chronic neck and shoulder pain of musculoskeletal origin" with low level laser diodes in the visible light spectrum, including red laser diode only (K012580, K152196), red and violet laser diode (K191257), and green and violet laser diode (this submission). The clinical data provided in this submission demonstrates simultaneously administering the combination of green and violet diode yields comparable (equivalent) or better (superior) results with respect to decrease in subjects' neck and shoulder pain, while maintaining the same safety profile as the predicate device, Erchonia EVRL (K191257) while simultaneously administering red and violet diodes, and the reference device Erchonia EVRL (K152196, K012580) while administrating red laser only. (See Table 1)

# 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. Therefore, the Erchonia® GVL (subject device) is substantially equivalent to the Erchonia® EVRL (predicate device), indicated for use while using the green and violet diode simultaneously for adjunctive use in providing temporary relief of minor chronic neck and shoulder pain of musculoskeletal origin and while using the violet diode, to treat dermatological conditions, and specifically indicated to treat moderate inflammatory Acne Vulgaris.
