Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Lesions suspected for melanoma will be tape stripped via the EGIR tape stripping method prior to biopsy. The tape will be applied to the site and briskly rubbed for a minimum of 15 circular motions and then removed. This process will be repeated 4 times so that 4 tape strips are collected altogether. Participants will have only one study visit in which this will be conducted. After the tape stripping procedure is completed, the lesion will be biopsied according to local standard procedure.

Comparator / control treatment
All participants will have tape stripping procedure on a site of normal skin to act as the control group. The same tape stripping process will apply, collecting a total of 4 strips from a site of normal skin.

Summary
Brief summary
This study evaluates a new non-invasive technique for early diagnosis of melanoma.
Who is it for? You may be eligible to join this study if you are at least 18 years old and have a pigmented lesion that is suspected of being a melanoma which requires surgical removal.
Trial details: This research study proposes to use a novel non-invasive method called Epidermal Genetic Information Retrieval or EGIR to assess skin lesions that are suspicious for melanoma. The method of retrieval is via tape stripping. Tape stripping allows recovery of cells of the upper epidermis (superficial most skin layer). These skin cells will be studied to identify markers capable of distinguishing between melanoma and benign (harmless) pigmented lesions. Unlike standard biopsies, tape stripping is non-invasive, rapid, easy to perform and painless. Therefore, the identification of such markers by this method could help physicians determine the nature of suspicious lesions of the skin without having to perform a biopsy. Tape stripping has been tested previously and has shown promise in identifying markers for other skin disorders and is now being tested through this research study for melanoma. All participants in this study will undergo collection of skin samples via the tape stripping procedure. The tape (0.7inches in diameter), similar to a band-Aid will be applied to the skin lesion and rubbed in circular motions. 4 skin tapes will be placed on the same skin lesion. A normal looking skin area (an area that does not have a lesion) will be used as a comparator. After the skin taping procedure is completed, the skin lesion will be biopsied or removed as per the normal clinical practice. The tape strips will be couriered to the Sponsor DermTech International where they will be analysed. The Biopsy specimen will be sent to a nominated pathologist for this study and results will be sent back to the investigator. The tissue slides will be sent to an independent pathologist for a second review.
