Veracyte Announces Presentation of Percepta™ Bronchial Genomic Classifier Clinical Validation Data at the 16th World Conference on Lung Cancer
SOUTH SAN FRANCISCO, Calif., Sept. 9, 2015 /PRNewswire/ -- Veracyte, Inc. (NASDAQ: VCYT), a molecular diagnostics company pioneering the field of molecular cytology, announced the presentation of data supporting the use of the Percepta Bronchial Genomic Classifier to help reduce unnecessary, invasive biopsies as part of lung cancer diagnosis. The findings will be presented today at the 16th World Conference on Lung Cancer, being held in Denver, Colo., September 6-9, 2015.
The multicenter study involved 163 current or former smokers who were undergoing bronchoscopy to evaluate lung nodules or lesions that were suspicious for cancer. Among the 123 patients whose bronchoscopy results were inconclusive – meaning that cancer could not be ruled out – the Percepta test identified patients at low risk of cancer with a high level of accuracy (negative predictive value of 94 percent). The genomic test and bronchoscopy had a combined ability to detect cancer (i.e., sensitivity) of 96 percent, compared to 51 percent for bronchoscopy alone. The findings being presented today appeared previously in a journal article describing the Percepta test's development.1
"Bronchoscopy is among the most common methods for evaluating suspicious lung nodules or lesions, but it frequently produces inconclusive results. This leaves physicians with the dilemma of whether to subject patients to invasive, expensive and potentially unnecessary diagnostic procedures or just monitor them, with the chance that they may have cancer," said Anil Vachani, M.D., associate professor of medicine at the Perelman School of Medicine at the University of Pennsylvania and an author of the study. "These data suggest that the Percepta test can potentially help physicians determine which patients are at low risk of cancer and can thus be followed with CT scans."
Through this study, along with the AEGIS I and II trials,2 the Percepta test has been validated on more than 1000 patients at over 30 medical centers.
"We believe that, collectively, data from these three, rigorous clinical studies support the use of the Percepta Bronchial Genomic Classifier to help patients with suspicious lung nodules avoid unnecessary invasive procedures, while also reducing healthcare costs," said Bonnie Anderson, Veracyte's president and chief executive officer. "The need for improved lung cancer diagnosis has become even more critical as millions of Americans recently became eligible for annual CT screening through their insurers."
Lung cancer is the leading cause of cancer deaths in the United States, killing nearly 160,000 Americans each year. An estimated 250,000 patients currently undergo a bronchoscopy for suspected lung cancer each year in the United States, with approximately 40 percent producing inconclusive results. This outcome can lead to invasive procedures, such as transthoracic needle biopsy (TTNB) and surgical lung biopsy (SLB), which are risky and expensive.
About the Percepta Bronchial Genomic Classifier
The Percepta Bronchial Genomic Classifier is designed to identify patients with lung nodules who are at low risk of cancer following an inconclusive bronchoscopy result, to enable these patients to be safely monitored with CT scans in lieu of invasive diagnostic procedures. The 23-gene molecular classifier uses proprietary genomic technology to detect molecular changes that occur in the epithelial cells lining the lung's respiratory tract in current or former smokers with lung cancer. These changes can be detected in cells obtained from standard cytology brushings taken during bronchoscopy from the mainstem bronchus and indicate the presence of malignancy or disease processes from distant sites in the lung. Thus, the test is designed to determine a lung nodule's or lesion's likelihood of cancer, without the need to sample the nodule or lesion directly. The Percepta test is performed at Veracyte's CLIA-certified laboratory in South San Francisco, Calif. The company began making the Percepta classifier available to a limited number of institutions around the United States in April 2015.
About Veracyte
Veracyte (NASDAQ: VCYT) is pioneering the field of molecular cytology, offering genomic solutions that resolve diagnostic ambiguity and enable physicians to make more informed treatment decisions at an early stage in patient care. By improving preoperative diagnostic accuracy, the company aims to help patients avoid unnecessary invasive procedures while reducing healthcare costs. Veracyte's Afirma® Thyroid FNA Analysis centers on the proprietary Afirma Gene Expression Classifier (GEC) and is becoming a new standard of care in thyroid nodule assessment. The Afirma test is recommended in leading practice guidelines and is covered for approximately 150 million lives in the United States, including through Medicare and many commercial insurance plans. Veracyte is expanding its molecular cytology franchise to other clinical areas, beginning with difficult-to-diagnose lung diseases. In April 2015, the company launched the Percepta™ Bronchial Genomic Classifier, a test to evaluate patients with lung nodules that are suspicious for cancer. Veracyte is developing a second product in pulmonology, targeting interstitial lung diseases, including idiopathic pulmonary fibrosis. For more information, please visit www.veracyte.com.
