DermTech Unveils DermTech Stratum, an Expanded Translational Medicine Service Offering for Non-invasive Biomarker Analysis

DermTech, Inc. (NASDAQ: DMTK) (“DermTech” or the “Company”), a leader in precision dermatology enabled by a non-invasive skin genomics platform, announced today the expansion and branding of its translational medicine service offering, DermTech Stratum™, which utilizes DermTech’s non-invasive technology and precision biomarker approaches to bring heightened precision and personalization to dermatologic disease diagnosis and treatment development. This broadened service offering leverages DermTech’s proprietary platform technology for biomarker analysis of RNA, DNA, protein and microbiome.

DermTech’s non-invasive Smart Sticker™ is used to painlessly collect cellular material from the surface of a patient’s skin for precision genomic and proteomic analysis. DermTech Stratum offers the opportunity for research partners and collaborators to non-invasively collect skin samples for analysis to identify biomarkers of disease and subgroups of disease, stratify patients based on genomic and proteomic profiles, enrich for responders in a population and predict and track responses to therapeutic intervention.

DermTech Stratum includes expert services such as biomarker identification, new target identification, patient segmentation and stratification, and bioinformatics support. The DermTech Stratum service offering is appropriate for indications where skin is the target or a surrogate target organ and are being used to support drug discovery and development programs focused on cancers and inflammatory diseases in clinical research studies.

“DermTech is continuing to pave the way for continued innovation in precision and personalized dermatology,” said Michael Howell, chief scientific officer of DermTech. “With a goal of helping to advance diagnostic tools and treatments to improve skin health, we are proud to introduce DermTech Stratum to the market.”

The DermTech Smart Sticker™ provides a 19mm collection area for lesional and non-lesional samples, collecting 1.5mg of stratum corneum tissue, eliminating the need for surgical biopsies in clinical research studies. Once collected, the sample does not require fixation or refrigeration and preserves genomic and proteomic material from the skin for up to 10 days at room temperature and more than a year when stored at -80 C.
