DermTech Presents New Data on the Pigmented Lesion Assay

VERITAS Vision System Is Introduced by Johnson & Johnson

The company will offer live demos of the new system in a wet lab at the Johnson & Johnson booth (#2813) this weekend at the 2021 American Society of Cataract and Refractive Surgery and American Society of Ophthalmic Administrators Annual Meeting.

FoodMarble AIRE Shown to Exceed the Performance of ‘Gold Standard’ SIBO Testing in Clinical Trial

SIBO is a very common disorder where there are excessive bacteria present in the small intestine. The true prevalence of SIBO in the general population is largely unknown, with some studies estimating its occurrence in up to 15% of healthy individuals. It is also largely associated with many other common clinical conditions, including irritable bowel syndrome, where 40-80% of IBS patients have SIBO.

Dr. Stephanie R. Jackson, MD, PhD, Department of Dermatology, University of Pittsburgh, presented, “Risk Stratification of severely dysplatic nevi (SDN) by non-invasively obtained gene expression and mutation data.” Using the DermTech Pigmented Lesion Assay (PLA), RNA gene expression and DNA mutation positivity were evaluated in pigmented lesions concerning for early melanoma. Dr. Jackson found that the addition of TERT mutation status increases the sensitivity of the PLA from 91% to 97%. TERT is a driver mutation found in many cancers, including early stage melanoma, that maintains the growth and survival of cancer cells. In addition, 61% of PLA gene expression positive lesions that were not diagnosed as melanoma were found to have severe histologic atypia. Because some clinicians prefer to treat lesions with severe histologic atypia with a full excision, identifying these lesions with the PLA provides important clinical utility and risk stratification of pigmented lesions. These data further validate the PLA in enhancing early melanoma detection based on genomic atypia. The addition of TERT mutation analyses to the test may further improve performance. Dr. Jackson was selected for the Rising Derm Star Competition for this work, placing second overall for her presentation.

“Genetic insight provided by the non-invasive PLA provides an objective basis for defining malignant potential, and the addition of TERT mutation analysis helps distinguish pigmented lesions with more aggressive biology,” said Dr. Jackson.

DermTech’s PLA was also included in CME sessions, “Genetic Expression Profiling Beyond Melanoma Prognosis” and “Integrating New Technologies into Dermatology Practice.”
