DermTech Presents New Research Differentiating Atopic Dermatitis and Psoriasis at the Society for Investigative Dermatology’s Annual Meeting

May 18, 2022 at 16:30 PM EDT

DermTech, Inc. (NASDAQ: DMTK) (“DermTech” or the “Company”), a leader in precision dermatology enabled by a non-invasive skin genomics platform, announced today its presentation at the Society for Investigative Dermatology’s (SID) annual meeting, held from May 18-21, 2022 in Portland, OR.

Michael Howell, Ph.D., chief scientific officer at DermTech, presented new research that enables the differentiation of the inflammatory signatures of atopic dermatitis from psoriasis in potential clinical trial participants. Howell presented the research during a live podium lecture at the International Psoriasis Council’s (IPC) symposium, titled “Getting real (world) with psoriasis: Advances in registries and real-world data in psoriasis.” A recording of the lecture is available here.

Titled “A Novel Expression Based, Non-Invasive Method to Differentiate Atopic Dermatitis and Psoriasis,” the presentation focused on the viability of conducting non-invasive skin sampling with the DermTech Smart Sticker™ to differentiate atopic dermatitis from psoriasis. By non-invasively collecting stratum corneum tissue, the Smart Sticker captures genomic material to objectively quantify changes that cannot be seen visually.

DermTech collected epidermal skin samples from patients with moderate to severe atopic dermatitis and psoriasis for this research study. RNA was isolated and analyzed for expression of specific biomarkers associated with atopic dermatitis and psoriasis, with IL-13, CCL17/TARC, CCL26/Eotaxin-3, IL-17A, CXCL9, CXCL 10, and NOS2 exhibiting the greatest differences. Using a machine-learning approach, DermTech identified a unique ratio that stratified patients into atopic dermatitis versus psoriasis.

Among the most diagnosed inflammatory skin conditions, atopic dermatitis and psoriasis affect up to 10% and 3% of the U.S. population, respectively. Dermatologists typically rely on visual assessment to diagnose and differentiate the two diseases. While the early symptoms of atopic dermatitis and psoriasis can overlap, long-term treatment plans and overall treatment costs do not. The ability to distinguish these two diseases through precision genomic analysis provides physicians with a valuable asset for clinical decision-making.

“We are honored to have been a part of the IPC’s symposium and to share our new research, which has the potential to enhance personalized treatment options for atopic dermatitis and psoriasis patients,” said Howell. “We are committed to being a resource to our research and development partners and bringing precision medicine to dermatology to help ensure the right patient is getting the right treatment at the right time.”
