Proof-of-Concept Research Demonstrates Patients Reliably Perform Remote Self-Sampling of Concerning Moles Using DermTech’s Non-Invasive Adhesive Skin Collection Kit Under Physician Supervision via Tel

LA JOLLA, CA, US - May 11, 2020 - DermTech, Inc. (NASDAQ: DMTK) (“DermTech”), a leader in precision dermatology enabled by a non-invasive skin genomics platform, today announced that SKIN, the official journal of the National Society for Cutaneous Medicine, published proof-of-concept data demonstrating that patients are able to reliably perform remote self-sampling of concerning moles using the DermTech Pigmented Lesion Assay (the “DermTech PLA”) under physician supervision via telemedicine, enabling actionable molecular testing for accurate melanoma detection.

As part of the Institutional Review Board (IRB) approved pilot study, 258 eligible melanoma survivors were contacted, and of the 211 who expressed interest in the DermTech PLA, there were seven cases of self-identified concerning lesions, which were confirmed by a clinician to be suspicious of melanoma. These patients then conducted sample collections using DermTech’s non-invasive adhesive skin collection kit at home under the supervision of a clinician via telemedicine.

Results from the study showed that skin samples collected by patients enabled successful PLA testing to objectively rule out melanoma in all (100%) of the cases evaluated. These findings are in line with sample collection results by licensed providers. 

In addition, survey findings indicated that anxiety around skin self-examination increased during COVID-19 due to the lack of, or limited, physician access. Responses also uncovered a desire among high-risk patients for accurate melanoma detection options for circumstances such as this.

“It is critical to catch and treat melanoma early for the best chance of survival,” said the lead author of the study, Dr. June K. Robinson, a dermatologist who is a Research Professor of Dermatology at the Northwestern University Feinberg School of Medicine. “This non-invasive remote sample collection option has the potential to bring greater peace of mind to patients, especially those who are at high-risk for melanoma. During a time when physician visits are limited, this at-home mole sample collection option is a benefit to the patient, who is likely anxious or concerned about a suspicious mole. The DermTech PLA allows me to offer quick and accurate results with this easy-to-use, trusted and validated test, which helps to determine if an office visit is necessary to surgically biopsy a mole that looks suspicious clinically. In over 90% of cases, the PLA helps to avoid an unnecessary surgical biopsy.”

“These findings come at a critical time, demonstrating the clinical utility of this remote sample collection approach during the COVID-19 pandemic. The DermTech PLA provides an effective and reliable solution to empower patients and physicians to remain vigilant and attentive to suspicious lesions, especially when physician access is limited,” said Burkhard Jansen, MD, Chief Medical Officer of DermTech. “Even as we move beyond the current shelter in place restrictions, non-invasive remote collection by the patient with the DermTech PLA, under the guidance of a clinician, has potential to expand patient access to important and objective testing for this deadly disease. Skin cancer doesn’t wait, and now patients don’t have to either.”

The DermTech PLA uses a revolutionary adhesive patch technology to collect skin cells from the surface of an entire lesion without a surgical biopsy, leaving the lesion intact to offer dermatologists the option for further analyses if necessary. The skin cells extracted from the patch are analyzed for gene expression associated with melanoma. The DermTech PLA is highly validated with proven clinical utility, and has a 91% sensitivity with less than a 1% chance of missing a melanoma (99% NPV). Since its launch in 2016, the DermTech PLA has been used to assess more than 50,000 lesions and remains the first and only non-invasive gene expression test in dermatology.

About Use of DermTech PLA Adhesive Skin Collection Kit Via Teledermatology:

A clinician can assess the patient’s skin and suspicious lesion(s) via a teledermatology appointment and, if indicated, submit an order for the DermTech PLA. Once requested by the clinician, the DermTech PLA Adhesive Skin Collection Kit is shipped directly to the patient with support from DermTech customer service. During a follow-up teledermatology appointment, the clinician will instruct and supervise the patient to collect their sample with the easy-to-use DermTech PLA adhesive collection kit. The patient will then return the collected sample(s) back to DermTech for analysis. Assay results will be available to the ordering clinician within a few days. A clinician can assess the patient’s skin and suspicious lesion(s) via teledermatology where permitted by state law. Clinicians should confirm applicable laws and third party payor reimbursement rules governing telemedicine visits.
