Intended Use

The AviClear Laser System is indicated for the long-term treatment of mild to severe inflammatory acne vulgaris.

Device Story

The AviClear Laser System is an infrared diode laser (1726 nm) used in dermatology clinics by trained operators. The device targets sebum within sebaceous glands to reduce sebum production and improve acne. It features a console with a touchscreen interface and a handpiece with an integrated scanner, sapphire cooling window (0°C to 5°C), and skin-contact pressure sensors. The operator selects treatment parameters via the touchscreen; the system delivers laser energy in a pattern while the cooling window protects the epidermis and superficial dermis. Laser activation requires both footswitch depression and verified skin contact. The thermal injury to sebaceous glands provides a therapeutic effect for acne vulgaris. The device is a non-sterile, reusable system.

Clinical Evidence

Prospective, multi-center clinical study (n=104; 57% female, 43% male; age 16-40). Primary endpoint: Treatment success (≥50% reduction in inflammatory lesions) at 12 weeks post-final treatment. Long-term effectiveness: 91.5% of subjects achieved treatment success at 52 weeks (p<0.001). Secondary endpoints: 66.2% of subjects achieved 'Clear' or 'Almost Clear' skin at 52 weeks; non-inflammatory lesion counts reduced by 57.6% at 52 weeks (p<0.001). Safety: No SAEs or SUADEs reported. Common AEs included transient erythema, edema, mild acne purging, and dryness. Average discomfort score 5.23 ± 1.15.

| Classification Name: | Powered Laser Surgical Instrument, GEX, 21 CFR 878.4810 |
| Legally Marketed<br>Predicate Device: | AviClear Laser System (K213461) |
| Indications for Use: | The AviClear Laser System is indicated for the long-term treatment of mild<br>to severe inflammatory acne vulgaris. |
| Device Description: | The AviClear Laser System is an infrared diode laser device with a nominal<br>wavelength of 1726 nm. Similar to other well-established infrared laser<br>devices, the device uses a combination of the treatment spot size, beam<br>characteristics, and tissue absorption and scattering coefficients at the |

e output wavelength to deliver energy to tissues at depth. The wavelength of the laser energy, when combined with the pre, parallel (during energy delivery), and post cooling of epidermal and superficial dermal structures, causes selective heating of dermal tissue at different depths. The 1726 nm laser enerqy heats the chromophore, sebum within sebaceous glands, which results in controlled thermal injury of the sebaceous glands, the ultimate treatment target, thus reducing or eliminating sebum production and causing an improvement in acne vulgaris.

> The diode laser and associated beam delivery optics, laser and electronics power supplies, control electronics, and cooling system are housed inside a console equipped with a touchscreen user interface. The laser treatment parameters are selected using the touchscreen.

> The treatment handpiece has an integrated scanner for delivering treatment spot(s) in an operator-selected pattern; a temperature-controlled skincontact cooling window to provide thermal protection for the epidermis and superficial dermis and through which energy is delivered to the patient; and skin-contact pressure sensors that enable laser energy delivery when the system is in Ready mode and the footswitch is depressed.

- Data for the clinical study was previously submitted under K213461, Results of Clinical Study: resulting in FDA 510k clearance for the treatment of mild to severe inflammatory acne vulqaris. This is a prospective, multi-center, clinical study to assess the safety and effectiveness of the Cutera AviClear Laser System for the treatment of mild to severe acne vulgaris. The study's primary effectiveness objective was to show more that than 50% of subjects enrolled were Responders who achieved Treatment Success, where Treatment Success was defined as a subject with ≥50% fewer inflammatory acne lesions with respect to baseline. Safety was assessed by a review of the totality of all reported adverse events and their resolutions, including assessments of treatment discomfort.

104 subjects, 57% female and 43% male, 16 to 40 years (avg. 22.2 ± 5.5), diagnosed with mild, moderate, and severe acne vulgaris were enrolled. Subjects received up to 3 treatments and were followed up through 52weeks post final treatment, with 12-weeks being primary end-point.

Details surrounding the Primary, Secondary Effectiveness as well as Safety Analysis have been outlined in the previous 510(K) summary submitted under K213461.

- . Long Term Effectiveness Analysis: At the 52-week post-finaltreatment follow-up visit, 91.5% of subjects achieved treatment success (p<0.001); thereby showing durable and efficacious results from the 12week post-final-treatment follow-up visit.
#### Secondary Effectiveness Analyses: ●

Improvement in Investigator's Global Assessment

- By the 52-week follow-up visit, the number of subjects had O increased to 66.2% for the Clear or Almost Clear skin categories.

{5}------------------------------------------------

## Section 7 510(k) Summary

Improvement from Baseline in Non-Inflammatory Lesion Counts

- The non-inflammatory lesion counts reduced from 25% (p=0.001) o at 12-week mark to 57.6% reduction from Baseline at the 52week follow-up assessment (p<0.001).
Subject Satisfaction

- Approximately 70% of subjects reported they were either "Very O likely" or "Likely" to have the laser treatment aqain at both the 12and 52-week follow-up visits.
- Safety Variable Analysis: All treatment sessions were well tolerated ● with an average discomfort score of 5.23 ± 1.15. No treatment sessions ended prematurely due to excessive treatment discomfort. No reports of serious adverse events (SAEs) and unanticipated adverse device effects of any severity (SUADEs/UADEs).

There were no residual adverse events at the 52-week mark. Adverse events through 12-week follow-up can be found outlined in previous 510(K) summary submitted under K213461. Most commonly reported adverse events from the 12-week mark are summarized below:

- As is expected with laser procedures, all subjects experienced o mild, transient erythema, while 98.1% of subjects experienced edema. Erythema self-resolved within minutes to hours, while edema self-resolved within hours to days.
- 45.2% of subjects experienced mild acne purging / flare-up; O typically resolving with no medical intervention.
- 18.3% of subjects experienced mild dryness; typically resolving O with application of topical skin moisturizers.
- There were no reports of blistering, hyper- or hypopigmentation, O or scarring adverse events in any subjects.

As demonstrated by the results of the clinical study, the AviClear Laser System continues to demonstrate safe and effective performance at the oneyear follow-up, thus supporting the claim for long-term treatment of mild to severe inflammatory acne vulgaris.

The technical specifications of the previously cleared AviClear Laser System and the subject device are identical, as tabulated below. However, the following minor design modifications were made to the subject device:

- . Slimmer handpiece body (no change to patient contact end of handpiece)
- Updated touchscreen user interface ●
