EktoTherix™ Regenerative Tissue Scaffold for Repair of Surgical Excision Wounds

Study Overview
=================
Brief Summary
-----------------
The purpose of study is to assess the safety and performance of EktoTherix™ Tissue Repair Scaffold in the treatment of full-thickness, dermatologic wounds created by the surgical removal of non-melanoma skin cancers. EktoTherix™ is a medical device developed by Neotherix Limited, manufactured by the polymer processing technique of electrospinning. Described as a tissue scaffold, EktoTherix is placed into the surgical wound to help the patients' own cells repair the wound, enhancing healing and improving quality (including cosmetic outcome). The tissue scaffold is completely absorbed by the body during the healing process, which means that there is no need to remove it when the wound is healed. All patients recruited into this study are treated with EktoTherix, are seen weekly until they heal and seen again at the final follow-up visit three months post-surgery. The investigators hypothesise that the use of EktoTherix will increase incidence of complete healing and result in an overall better cosmetic result of the healed wound.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Is the patient at least 18 years of age Is the patient male, or is not pregnant or lactating and is using contraception Has the patient been diagnosed with a non-melanoma skin cancer (basal cell carcinoma BCC or squamous cell carcinoma SCC) for which the chosen therapeutic option is surgical excision followed by secondary intention healing Is the excisional wound greater than 10mm x 10mm in size and less than or equal to 35mm x 35mm after any attempt at primary closure Does the patient have limited skin laxity which would make primary closure of the surgical excision difficult Is the patient able to understand the aims and objectives of the trial and are they willing to consent Exclusion Criteria: Has the patient been diagnosed with any transmittable viral diseases (HIV, Hepatitis B or C) Has the patient been diagnosed with, or is it suspected that they have metastatic disease Does the patient have a history of malignant melanoma or any concomitant disease likely to impede wound healing Has the patient been diagnosed with pre-existing wound infection Is the patient taking any medication known to interfere with skin grafts (i.e. warfarin and other anticoagulants, steroids, NSAIDs and immunosuppressants) Has the excised wound been entirely treated by primary closure Does the patient have a history of any significant cardiac, pulmonary, renal, hepatic, neurological and/ or immune dysfunction that may affect wound healing Does the patient know of any allergy to any of the device materials to be used in the trial Does the patient have a known history of poor compliance with medical treatment Has the patient participated in this trial previously and healed or been withdrawn Is the patient currently participating in any other clinical trial

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: EktoTherix<br>One application of the EktoTherix scaffold to a fresh wound resulting from a full thickness excision of skin cancer. | Device: EktoTherix<br>* The EktoTherix scaffold is applied to the fresh wound resulting from a full thickness excision of non-melanoma skin cancer and then bolstered by the application of a non-adhesive foam dressing (discontinued at the first visit); both scaffold and foam dressing are secured in place using a semi-occlusive film dressing. The EktoTherix-treated wound is assessed weekly as per standard of care.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidence of device related adverse events | The primary endpoint of the study is to demonstrate the safety of the EktoTherix Tissue Repair Scaffold through the incidence of device related adverse events identified during the study, including clinical infection, whether the wound has healed by the final clinical assessment and any clinically significant laboratory results at three month post-surgery assessment. | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cosmesis (cosmetic outcome is assessed by the Vancouver Burn Scar Assessment Scale (VBSAS) score (clinician's assessment) and by a Visual Analogue Scale (VAS) | The cosmetic outcome is assessed by the Vancouver Burn Scar Assessment Scale (VBSAS) score (clinician's assessment) and by a Visual Analogue Scale (VAS) score (patient's assessment). The VBSAS scale assigns a numerical score by summing individual ratings for pigmentation, vascularity, pliability and height or depression of the wound or scar. The VAS score is a number, between the worst (0) and the best (ten) cosmetic outcome, representing the patient's perception of the treatment. The cosmetic outcome is evaluated when the wound is healed (if prior to or on Day 42 Post-surgery Assessment) and at the 3 Month Post-surgery Assessment. | 3 months |
