## Device Story

NeoMatriX is a sterile wound dressing derived from axolotl dermal extracellular matrix; provided as sheets for placement on wound beds. Device acts as an adherent covering to protect wound from environment; manages wound environment. Used in clinical settings by healthcare providers; applied directly to patient skin surface for 3-7 days. Provides physical barrier to support healing. Benefits include wound protection and management of various chronic and acute wound types.

## Clinical Evidence

Clinical evidence includes immunogenicity testing in healthy human subjects: Human Repeated Insult Patch Test (HRIPT) (n=68) and Skin Prick Test (SPT) (n=22). No reactions observed in either study. Animal testing (porcine model) compared NeoMatriX to predicate, showing no inhibition of wound healing, comparable re-epithelialization rates, and no necrosis.

## Technological Characteristics

Sterile, decellularized collagen sheet derived from axolotl dermal extracellular matrix. Terminally sterilized via gamma irradiation (ISO 11137, VDmax methodology). Biocompatibility per ISO 10993-1; endotoxin testing per AAMI ST72.

# Description

NeoMatriX Wound Matrix is a sterile, wound dressing fabricated from the dermal extracellular matrix of axolotl. This device is derived from an amphibian farm-raised hybrid axolot! source from a closed herd in a dedicated facility. NeoMatriX is provided as sheets of various sizes for placement on wound beds to help manage the wound environment. This device is terminally sterilized using gamma irradiation.

NeoMatriX wound matrix provides an adherent covering that protects the wound from the environment. The device is intended for one time use.

### Indications for Use

NeoMatriX® Wound Matrix is intended for management of wounds, including:

- Partial and full-thickness wounds,
- . Pressure ulcers,

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

- Venous ulcers, ●
- Diabetic ulcers,
- Chronic vascular ulcers,
- . Tunneled / undermined wounds,
- Surgical wounds (donor sites / grafts, Moh's surgery, post-laser surgery, podiatric, and . wound dehiscence),
- . Trauma wounds (abrasions, lacerations, second-degree burns, and skin tears),
- . Draining wounds.

The device is intended for one-time use.

# Substantial Equivalence

NeoMatriX Wound Matrix has the same intended use as the predicate devices, which are all for management of wounds. The indications for use are also the same as the predicates. The technological characteristics of NeoMatriX Wound Matrix are substantially similar to the predicates, as all are provided in the form of sheets of decellularized collagen (extracellular matrix) that are placed on the surface of the patient's skin. Each of the collagen materials is obtained from animal tissue. All of the materials are processed to remove cellular material and for viral inactivation, and all are terminally sterilized. The NeoMatriX™ Wound Matrix and its predicates are applied directly to the wound, on the surface of the patient's skin for a specified time period (3 to 7 days). The main difference between the NeoMatriX Wound Matrix and the identified predicates is the animal source of collagen, which is the axolot for NeoMatriX. However, this difference does not raise different questions of safety or effectiveness, as the key questions of biocompatibility, mechanical/physical properties, and safety for use in healing wounds are common to all devices. Furthermore, biocompatibility, performance testing, animal testing, and human clinical testing demonstrates that the device has appropriate properties for its intended use.

# Performance Data

#### . Biocompatibility Testing

NeoMatriX Wound Matrix was subjected to the following biocompatibility testing per the ISO-10993-1 standard: cytotoxicity, sensitization, irritation/intracutaneous reactivity, acute systemic toxicity, pyrogenicity, subacute and subchronic toxicity, and genotoxicity. The results showed that NeoMatriX Wound Matrix meets biocompatibility requirements of the ISO standard. Endotoxin testing was conducted according to AAMI ST72. Viral inactivation testing was also performed.

#### Sterilization Validation ●

NeoMatriX Wound Matrix is sterilized using gamma radiation to a sterility assurance level of 10°. In addition to application of the VDmax methodology, the gamma sterilization cycle is designed and validated per ISO 11137.

#### Bench Testing .

In vitro physio-chemical testing was conducted to demonstrate the chemical composition and physical characteristics of NeoMatriX Wound Matrix.

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

#### Animal Testing .

NeoMatriX Wound Matrix was subjected to porcine testing to demonstrate the performance of the device. Results showed that NeoMatriX did not inhibit wound healing when compared to the predicate device. No evidence of adverse effects was observed for either the NeoMatriX or predicate wound dressings. The two devices resulted in no inhibition or difference in the rate of re-epithelization. Histopathology revealed no necrosis observed in the superficial or deep wound beds treated with the NeoMatriX or the predicate device. Epithelialization was comparable between the treatment groups.

### Clinical Testing ●

Immunogenicity testing was conducted in human subjects to further support the device. The clinical testing included a Human Repeated Insult Patch Test (HRIPT) in 68 healthy subjects and a Skin Prick Test (SPT) in 22 healthy human subjects. No reaction to NeoMatriX Wound Matrix was observed at any site in either clinical investigations, indicating that NeoMatriX Wound Matrix does not raise immunogenicity concerns when used in humans.

# Conclusions

NeoMatriX Wound Matrix and its predicate devices have intended use and similar technological characteristics. The differences do not raise different questions of safety or effectiveness. Performance testing further demonstrates that the device is substantially equivalent to the predicate for its intended use.
