Safety, Tolerability and Performance of SmartMatrix Dermal Replacement Scaffold

Proof of Concept Study Assessing Safety, Tolerability and Performance of SmartMatrix Dermal Replacement Scaffold

SmartMatrix™ is a single layer dermal replacement scaffold for full thickness skin replacement. The scaffold consists of a porous matrix of cross-linked human fibrin plus alginate that has been designed and optimised to facilitate wound closure and healing through cellular ingress and rapid growth of new blood vessels.

This proof of concept study will involve patients with surgical wounds resulting from the excision of basal cell carcinoma (BCC) and squamous cell carcinoma SCC).

Inclusion Criteria:

• Expected defect following surgery ≥3cm, ≤6cm in diameter
• Patient or authorised representative able to comprehend and sign the Informed Consent prior to enrolment in the study

Exclusion Criteria:

• Aged <18 years of age
• Pregnant or lactating females
• Skin lesion >4cm in diameter or size that will result in post-surgical defect >6cm in diameter
• Lesion located over joint, i.e. ankle or knee
• Patient who are smokers
• Diabetic patients
• Patients diagnosed with peripheral vascular disease or venous stasis
• Patients receiving regular systemic steroids
• Patients who are immuno-compromised (either acquired or congenital)
• Patients with a known coagulopathy (either acquired or congenital) but not including patients on aspirin or other anti-platelet therapy
• Patients who have received radiotherapy treatment to the area about to be treated with Smart Matrix
• Concurrent participation in another experimental intervention or drug study
• Unwilling or unable to provide informed consent
