Veracyte Announces New Clinical Utility Data Suggesting Envisia Genomic Classifier Enables as Confident a Diagnosis in IPF as Surgical Pathology

- Interim CATALYST Study Findings Presented at PFF Summit -

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Veracyte, Inc. (NASDAQ: VCYT) announced that new data for the Envisia™ Genomic Classifier were presented today and demonstrate that the test - in real-world clinical scenarios - can enable diagnosis of idiopathic pulmonary fibrosis (IPF) by a central multidisciplinary team (MDT), without the need for surgery. The findings are important because IPF is often challenging to distinguish from other interstitial lung diseases (ILDs) without invasive, costly and risky surgery. The new data were shared during the Pulmonary Fibrosis Foundation's biannual PFF Summit, being held November 9-11 in Nashville, Tenn.

In the interim report from the CATALYST clinical utility study, researchers found that two central MDTs - each comprised of a pulmonologist, radiologist and pathologist - diagnosed patients with suspected IPF similarly (92 percent agreement) when they were randomly assigned to review either the patients' surgical pathology or Envisia classifier results, along with clinical information and high-resolution computed tomography (HRCT). The study also showed that the Envisia classifier enabled the MDTs to agree on a diagnosis (94 percent agreement) based on Envisia classifier results, even when surgical pathology results were inconclusive. The findings are from a retrospective analysis involving 71 patients who were evaluated for potential IPF using HRCT, surgical pathology and genomic testing with the Envisia classifier.

"These findings signal a real potential for a shift in the current diagnostic evaluation of patients undergoing evaluation for ILD," said Neil M. Barth, M.D., chief medical officer of Veracyte. "Prior to the introduction of the Envisia classifier, clinicians and patients were limited to surgery for confirming a diagnosis of IPF, if the HRCT was inconclusive. Many patients are not willing or medically eligible to undergo such an invasive procedure. Envisia has now been shown to enable as confident a diagnosis in IPF as surgical pathology. This removes many of the previous barriers to achieving a timely and accurate diagnosis."

About Interstitial Lung Disease and Idiopathic Pulmonary Fibrosis

Each year in the United States and Europe, up to 200,000 patients are evaluated for suspected ILD, including IPF, which is among the most common, deadly and difficult to diagnose of these lung-scarring diseases. Physicians routinely use HRCT to help identify IPF, but this approach frequently provides inconclusive results, leading many patients to undergo invasive and potentially risky surgery for a more definitive diagnosis. Other patients are too frail to undergo surgery and may never receive an accurate diagnosis, which can result in suboptimal - and potentially harmful - treatment.

About the Envisia Genomic Classifier

The Envisia Genomic Classifier is designed to improve physicians' ability to differentiate IPF from other ILDs without the need for surgery. The 190-gene classifier uses machine learning coupled with powerful, deep RNA sequencing to detect the presence or absence of usual interstitial pneumonia (UIP), a classic diagnostic pattern whose presence is essential for the diagnosis of IPF, using patient samples obtained through less-invasive transbronchial biopsy.
