ECRI Completes Evaluation of the Pigmented Lesion Assay (PLA), the Foundational Assay for the DermTech Melanoma Test (DMT)

- Health insurance plans and health systems use ECRI’s technology reviews to formulate coverage policies and clinical protocols

DermTech, Inc. (NASDAQ: DMTK) (“DermTech” or the “Company”), a leader in precision dermatology enabled by a non-invasive skin genomics platform, today announced that ECRI completed its evaluation of the Pigmented Lesion Assay (PLA), the foundational assay for the DermTech Melanoma Test (DMT), and changed its rating from ‘Inconclusive’ to ‘Somewhat Favorable’. ECRI is an independent, nonprofit organization focused on healthcare technology evaluation and safety to improve quality, reduce cost and achieve better outcomes across all healthcare settings.

“ECRI recently concluded an unbiased assessment of our clinical data for the DMT,” said Chris Murphy, senior director of payer access, DermTech. “ECRI determined that our test may inform clinician decision-making to recommend surveillance rather than biopsy for uncertain lesions with low melanoma risk. As health insurance plans and health systems rely on the independence and precision of ECRI’s technology evaluations to inform coverage policies and clinical protocols, we believe this is another important step that encourages payers to recognize the value of our test and resulting benefits to their membership and network providers.”

About The DermTech Melanoma Test

DermTech originally marketed its foundational assay under the name Pigmented Lesion Assay (PLA). The PLA assesses pigmented skin lesions, moles or dark skin spots for melanoma. In particular, the PLA detects expression of the LINC00518 (LINC) and preferentially expressed antigen in melanoma (PRAME) genes using reverse transcription-polymerase chain reaction (RT-PCR). The Company introduced its second-generation test in 2021 as an add-on assay to PLA, which is designed to identify the presence of mutations in TERT gene promoter region using DNA sequencing. The Company has since branded its PLA and TERT add-on-assay as the DermTech Melanoma Test (DMT). The DMT may be ordered with or without the add-on test for TERT. Positive results for LINC, PRAME or TERT correlate with a lesion at higher risk for melanoma. If none of the biomarkers are detected, this result indicates a greater than 99% probability that the mole being tested is not melanoma.
