Veracyte Achieves Major Medicare Milestone for the Envisia Genomic Classifier

First Test for Improved IPF Diagnosis Receives Draft Local Coverage Determination Through the MolDx Program

Veracyte, Inc. VCYT announced that it has received a draft Medicare local coverage determination (LCD) for the Envisia Genomic Classifier through the MolDx program. WPS Health Solutions posted a draft policy today, and the three other MACs (CGS, Noridian Health Solutions and Palmetto GBA) that participate in the Palmetto GBA-administered MolDx program are expected to issue similar LCDs. The Envisia classifier, which is built on next-generation RNA sequencing and machine learning technology, is the first test to achieve this significant Medicare coverage milestone for use in diagnosing idiopathic pulmonary fibrosis (IPF). Upon anticipated finalization, Envisia will become Veracyte's third genomic test to gain Medicare coverage since the company's founding in 2008.

Veracyte estimates that each year in the United States and Europe, up to 200,000 patients are evaluated for suspected interstitial lung diseases (ILD), including IPF, which is among the most common, deadly and difficult to diagnose of these lung-scarring diseases. Veracyte estimates that half of the patients evaluated in the United States are covered by Medicare.

"We applaud the MolDx program for taking this important step to make the Envisia classifier widely available to Medicare patients," said Bonnie Anderson, Veracyte's chairman and chief executive officer. "The evidence supporting use of the Envisia classifier met MolDx's high bar for coverage and strongly positions us to expand commercialization of the test in 2019."

The draft policy is open to a 45-day comment period and Veracyte anticipates that the final policy will go into effect in early 2019. Veracyte's tests for improved diagnosis of thyroid cancer (Afirma) and lung cancer (Percepta) received Medicare coverage in 2012 and 2016, respectively.

"Timely, accurate diagnosis of IPF is essential so that patients can receive optimal treatment, including new therapies that can slow progression of this deadly disease," said Fernando J. Martinez, M.D., chief of the Division of Pulmonary and Critical Care Medicine at Weill Cornell Medicine, who is also a scientific advisor for Veracyte (the Envisia test maker). "Alas, IPF remains difficult to diagnose, with a challenge in distinguishing it from other interstitial lung diseases that can lead to diagnostic delay and, potentially, inappropriate therapy."

The Envisia Genomic Classifier helps differentiate IPF from other ILDs without the need for surgery. The test is used as a complement to high-resolution computed tomography (HRCT) to enable clinicians to make a more confident diagnosis. Envisia evaluates patient samples that are obtained through transbronchial biopsy, a nonsurgical procedure that is commonly used in lung evaluation. The 190-gene test detects a genomic pattern of usual interstitial pneumonia (UIP), a hallmark of IPF, with high accuracy (88 percent specificity and 70 percent sensitivity).

In May 2018, Veracyte launched an Early Access Program to begin making the Envisia Genomic Classifier available to patients through select institutions around the country. The company estimates that the market opportunity for the Envisia classifier in the United States and Europe is approximately $525 million.

About Interstitial Lung Disease

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 along with a clinical work-up 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.
