Intended Use

Sebacia Microparticles are indicated for use as an accessory to 1064 nm lasers to facilitate photothermal heating of sebaceous glands for the treatment of mild to moderate inflammatory acne vulgaris.

Device Story

Sebacia Microparticles are a non-sterile, single-use topical suspension containing silica-core, gold-shell, polyethylene glycol-coated microparticles. Applied to the face and massaged into the skin, the particles act as an accessory to commercially available 1064 nm Nd:YAG lasers. The laser energy is absorbed by the microparticles, inducing localized selective photothermolysis of sebaceous glands. Used in a clinical setting by a healthcare provider, the device allows for effective acne treatment using lower laser fluences and fewer treatment sessions compared to laser-only therapy. The procedure aims to reduce inflammatory lesion counts, providing a therapeutic benefit for patients with acne vulgaris.

Clinical Evidence

Randomized, controlled, parallel-group clinical study (n=168) comparing Sebacia Microparticles + 1064 nm laser vs. laser alone. Primary endpoint: % reduction in inflammatory lesion count (ILC) at Week 12. Results: SM + Laser (mean 40.17%, median 53.33%) vs. Laser Alone (mean 41.89%, median 45.45%). Secondary endpoints (e.g., IGA clear/almost clear) were supportive. SM + Laser group required fewer treatment sessions (median 3.0 vs 6.0) and lower mean fluence (29.44 J/cm² vs 48.93 J/cm²). Safety profile was positive with no severe or serious treatment-related adverse events.

Technological Characteristics

Microparticles consist of a silica core, gold shell, and polyethylene glycol coating. Designed for use with 1064 nm Nd:YAG lasers meeting specific parameters: fluence 20-35 J/cm², 30 ms pulse duration, and 5-15 mm spot size. Biocompatibility tested per ISO 10993-1. Non-sterile, single-use topical suspension. Shelf-life: 2 years.

Indications for Use

Indicated for patients with mild to moderate inflammatory acne vulgaris.

#### Predicate Devices

Sebacia Microparticles are an accessory to legally marketed 1064 nm medical lasers intended for dermatologic use, and specifically for the treatment of mild to moderate inflammatory acne vulgaris, such as the 1064 nm Nd:YAG Cutera CoolGlide Aesthetic Lasers (K153671).

The predicate device is the 1064 nm Nd:YAG Cutera CoolGlide Aesthetic Lasers (K153671). This device is one example of a legally marketed device meeting the specifications for use with the Sebacia Microparticles.

#### Device Description

Sebacia Microparticles are a non-sterile, single-use product that is topically applied to the face for the purpose of supporting and supplementing the performance of legally marketed 1064 nm medical lasers for dermatologic use. The liquid suspension contains microparticles comprised of a silica core wrapped in a gold shell and coated with polyethylene glycol. The Sebacia Microparticles are topically applied to the face followed by gentle agitation of the skin surface using a mechanical massager and irradiated with a commercially available 1064 nm laser that heats the microparticles resulting in localized selective photothermolysis. The legally marketed 1064 nm medical laser used with the Sebacia Microparticles must meet the following specifications:

{4}------------------------------------------------

- o Fluence ranging from 20 J/cm2 to 35 J/cm²
- o Pulse duration of 30 ms
- At least 5-15mm spot size

# Intended Use / Indications for Use

Sebacia Microparticles are indicated for use as an accessory to 1064 nm lasers to facilitate photothermal heating of sebaceous glands for the treatment of mild to moderate inflammatory acne vulgaris.

## Performance Data

# Nonclinical Testing

Sebacia Microparticles were tested ex vivo for photothermal heating ability, biocompatibility (in accordance with ISO 10993-1) and shelf life. All results met predetermined performance criteria. The established shelf-life for the product is two (2) years based on real-time stability testing data. Three animal studies in a porcine model were performed to evaluate formulation and laser parameters, as well as safety, prior to the commencement of clinical testing. The results of animal testing demonstrate that Sebacia Microparticles meet prospective product requirements for functionality and safety.

### Clinical Studies

A randomized, controlled, parallel group, clinical study with blinded assessment was conducted in the U.S. to evaluate the Sebacia Microparticles when used with a 1064 nm Nd:Yag laser in facial mild to moderate inflammatory acne vulgaris. A total of 168 subjects received treatment, with approximately half of the subjects receiving the Sebacia Microparticles with laser ("SM + Laser") treatment and the other half receiving Laser Alone. Results are summarized in the table below:

| | SM + Laser<br>(n = 86) | Laser Alone<br>(n = 82) |
|-------------------------------------------------------|------------------------|-------------------------|
| PRIMARY ENDPOINT | | |
| % reduction in ILC (Baseline to Week 12); mean | 40.17 | 41.89 |
| % reduction in ILC (Baseline to Week 12); median | 53.33 | 45.45 |
| SECONDARY ENDPOINTS | | |
| % with ≥ 40% ILC reduction at Week 12 | 64.4 | 56.5 |
| % with IGA clear/almost clear at Week 12 | 30.1 | 31.9 |
| absolute reduction in ILC (Baseline to Wk 12); mean | 8.4 | 8.5 |
| absolute reduction in ILC (Baseline to Wk 12); median | 11.0 | 9.0 |
| TREATMENT PARAMETERS | | |
| laser fluence (J/cm²); mean | 29.44 | 48.93 |
| laser fluence (J/cm²); median | 30.00 | 49.79 |
| number of treatment sessions (All Patients); mean | 2.9 | 5.3 |
| number of treatment sessions (All Patients); median | 3.0 | 6.0 |
| number of treatment sessions (Completers); mean | 3.0 | 5.8 |
| number of treatment sessions (Completers); median | 3.0 | 6.0 |

# EFFECTIVENESS AND TREATMENT PARAMETER RESULTS

ILC = inflammatory lesion count

Percentage reduction in inflammatory lesion count from Baseline to Week 12 was assessed, revealing similar acne treatment effects for each group. Analyses of the secondary endpoints were supportive of the primary effectiveness analyses with results indicative of similar acne treatment effects for

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

SM + Laser when compared to Laser Alone. Summary results for subject satisfaction revealed that more subjects reported "Complete Improvement" or "Marked Improvement" in the SM + Laser treatment group than in the Laser Alone group. Analyses of overall mean fluence and the number of treatment sessions clearly demonstrated that use of fewer treatments and lower laser fluences in the SM + Laser Group resulted in equivalent reduction in mild to moderate inflammatory acne lesions when compared to the reduction in the Laser Alone Group.

Treatment with the Sebacia Microparticles also demonstrated a positive safety profile. The most frequent adverse events reported in both treatment groups were primarily general illnesses and complaints that were unrelated to study treatment. Furthermore, over 90% of the AEs reported in each treatment group were unrelated to study treatment. All reported AES, regardless of study treatment were of mild to moderate intensity. There were no severe AEs nor were there any serious and/or unanticipated adverse events related to study treatment.

# Conclusions

Sebacia Microparticles are indicated for use as an accessory to 1064 nm lasers to facilitate photothermal heating of sebaceous glands for the treatment of mild to moderate inflammatory acne vulgaris. In sum, the non-clinical and clinical data support the substantial equivalence of the Sebacia Microparticles to the predicate device for the proposed indications.
