A Sample Collection Study Utilizing DermTech's Non-invasive Adhesive Patch Biopsy Kits

• Conditions: Dermatologic Diseases

• Registration Number: NCT04668846
• Lead Sponsor: DermTech

Brief Summary

This sample collection study will recruit subjects with a variety of skin conditions from up to 15 geographically dispersed sites in the United States. Skin samples will be collected with the DermTech Adhesive Patch Kit from both lesional and non-lesional skin. Subjects may also be asked to return at a future data for additional collections. Collected skin samples will be analyzed for gene expression information, DNA and the microbiome.

Detailed Description

This is a multi-center, sample collection study to obtain skin tissue for gene expression, DNA mutation, microbiome and related analyses from subjects with dermatologic conditions. After subjects are consented for the study, site staff will collect skin tissue from the subject using DermTech's non-invasive skin collection kit. Skin samples will be collected from both lesional and non-lesional skin as applicable.

Additional skin tissue may be collected from the lesion and non-lesional area with the DermTech non-invasive skin collection kit at a later time point as directed by DermTech to track the dermatologic condition for progression, improvements or lack of response to standard of care therapy.

Each Dermtech non-invasive skin collection kit will consist of the sequential application of up to 24 individual patches to lesional and non-lesional areas. Sites should apply the DermTech patches to the most severe lesion(s).

Dermatologic conditions include but are not limited too; atopic dermatitis, atopic asthma, skin cancers (i.e., basal, and squamous carcinoma, melanoma, etc.), lupus, rheumatoid and psoriatic arthritis, gutate and plaque psoriasis, palmoplantar psoriasis, palmoplantar contact dermatitis, fungal infections and cutaneous T cell Lymphoma. Skin tissue will be collected using DermTech's proprietary adhesive patch skin biopsy kit and extracted for analysis at DermTech's CLIA and CAP Laboratory. Analysis of the samples will include gene expression signatures and DNA mutation as well as microbiome analyses associated with the medical conditions of interest.
