## Intended Use

Rx Indications: Alevicyn SG Antimicrobial Gel is intended to moisten the wound bed and facilitate autolytic debridement of acute and chronic dermal lesions. Alevicyn SG Antimicrobial Gel is indicated to manage and relieve the burning, itching, erythema, scaling, and pain experienced with various types of dermatoses, including atopic dermatitis, radiation dermatitis, seborthea and sebortheic dermal irritation, sores, injuries, and ulcers of dermal tissue in addition to moistening and lubricating absorbent wound dressings. The Alevicyn SG Antimicrobial Gel may also be used to manage partial or full thickness wounds such as first and second degree burns, stage I - IV pressure ulcers, diabetic and stasis ulcers, abrasions and skin irritations, surgical wounds (donor and graft sites, incisions), and trauma wounds. Alevicyn SG Antimicrobial Gel helps to relieve dry waxy skin by maintaining a moist wound & skin environment, which is beneficial to the healing process. OTC Indications for Use: Alevicyn SG Antimicrobial Gel is intended for OTC use to relieve itch and pain from minor skin irritations, minor cuts, exit sites, minor abrasions and minor burns, including sunburns. Hydrogel is also intended to moisten and lubricate absorbent wound dressings and moisten the wound bed. A moist wound and skin environment facilitates autolytic debridement and is beneficial to wound management and the healing process.

## Device Story

Alevicyn SG Antimicrobial Gel is an opaque, low-viscosity, topical spray gel. It functions as a skin emollient and moisturizer to maintain a moist wound environment, facilitating autolytic debridement and relieving symptoms like pain, itching, and burning. The device is applied topically to the wound bed or skin; it can also be used to moisten absorbent wound dressings. It is intended for use by healthcare professionals (Rx) or patients (OTC) in clinical or home settings. The gel contains hypochlorous acid and sodium hypochlorite as preservatives. By maintaining moisture, it supports the natural healing process of various dermal conditions and wounds.

## Clinical Evidence

Bench testing only. Testing included biocompatibility (cytotoxicity, irritation, sensitization per ISO 10993-1), toxicological risk assessment, and antimicrobial preservative effectiveness testing against Proteus mirabilis, Serratia marcescens, MRSA, and Acinetobacter baumannii. Physical characterization included pH, viscosity, and Free Available Chlorine (FAC) analysis.

## Technological Characteristics

Opaque, semi-viscous spray gel. Ingredients: water, sodium lithium magnesium fluorosilicate, dimethicone, sodium phosphate, sodium bicarbonate, sodium chloride, sodium sulfate, hypochlorous acid, and sodium hypochlorite. Non-sterile, preserved per USP <51>. Delivered via PET bottle with finger pump sprayer.

Dear Mr. Martin:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you; however, that device labeling must be truthful and not misleading.

The geometric design is a circular shape made up of intersecting curved lines in gray and teal. The company name "Sonoma" is in gray, and the word "PHARMACEUTICALS" is in teal below it.

#### VIII. PERFORMANCE DATA

The following performance data were provided in support of the substantial equivalence determination.

# Biocompatibility Testing

The biocompatibility evaluation for the Alevicyn SG Antimicrobial Gel was conducted in accordance with the FDA biocompatibility guidance issued on June 16, 2016 and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1 : Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The Alevicyn SG Antimicrobial Gel was evaluated for cytotoxicity, irritation, sensitization. In addition, a toxicological risk assessment was conducted to support the prolonged use of the device.

# Bench Testing

The following tests were performed to support the performance of Alevicyn SG Antimicrobial Gel: visual inspection, pH, viscosity, Free Available Chlorine (FAC) and Antimicrobial Preservative Effectiveness Testing against the following bacteria in the gel while on the shelf: Proteus mirabilis, Serratia marcescens, antibiotic resistant Methicillin-Resistant Staphylococcus aureus (MRSA), and Acinetobacter baumannii. The Alevicyn SG Antimicrobial Gel meets specification and performance characteristics and is substantially equivalent to the predicate devices.

#### IX. CONCLUSION

Alevicyn SG Antimicrobial Gel is substantially equivalent in intended use, technological characteristics, safety and effectiveness to Alevicyn SG Gel (K152945), and Puracyn Plus Antimicrobial Gel (K150799). Therefore, the Alevicyn SG Antimicrobial Gel is substantially equivalent to the predicate devices.
