Findings Presented at ATS 2022

Veracyte, Inc. (Nasdaq: VCYT) today announced new data showing that its Percepta Nasal Swab test accurately assesses lung cancer risk among current and former smokers with lung nodules, regardless of their smoking history burden and whether they are considered high risk for lung cancer based on U.S. Preventive Services Task Force (USPSTF) screening criteria. The findings were presented today at the American Thoracic Society 2022 International Conference (ATS 2022), being held in San Francisco.

“Our analysis showed that the nasal genomic classifier performed similarly well in patients across the spectrum of tobacco-related risk," said Carla R. Lamb, M.D., a pulmonary and critical care physician and Director of Interventional Pulmonary at Lahey Hospital & Medical Center who presented the study findings. “These findings suggest that the test can be reliably used in ever-smokers whose lung nodules were found incidentally, as well as through screening.”

For the study, researchers evaluated data from a subset of 291 current and former smokers with lung nodules who were part of the original clinical validation study for the Percepta Nasal Swab test. Among these individuals, 213 (73%) met USPSTF screening criteria (pack years ≥20, years since quit <15, age 50-80 years), while 78 (27%) did not. Researchers compared the performance of the classifier in the two patient subsets and found no statistically significant differences in the classifier’s sensitivity and specificity between the two groups.

Specifically, among those who met the USPSTF criteria for lung cancer screening, the test’s sensitivity was 96% when it identified a nodule as low risk for cancer and its specificity was 94% when it identified it as high risk. Among patients who did not meet the USPSTF lung cancer screening eligibility, the test’s sensitivity was 100% when it identified nodules as low risk for cancer and its specificity was 88% when it identified them as high risk.

“The data presented today reinforce the important role that the Percepta Nasal Swab classifier may play in helping to guide next steps for current and former smokers with lung nodules – including those who may be considered low risk based on their smoking history burden,” said Giulia C. Kennedy, Ph.D., Veracyte’s global chief scientific officer and chief medical officer. “More accurate, timely diagnosis of these patients could ultimately lead to fewer unnecessary diagnostic procedures among those without lung cancer, and timelier treatment for those with the disease.”

The Percepta Nasal Swab test’s performance in classifying lung cancer risk has previously been demonstrated, and it is being made available to a limited number of sites as the company develops the clinical utility evidence to support reimbursement.

Also at ATS 2022, Veracyte will host two Learning Theater events during which leading physicians will discuss their experiences incorporating novel genomic testing into the diagnoses of interstitial lung disease (ILD) and lung cancer, respectively:
