SOUTH SAN FRANCISCO, Calif., May 11, 2017 /PRNewswire/ -- Veracyte, Inc. (NASDAQ: VCYT), a genomic diagnostics company focused on reducing unnecessary surgeries and healthcare costs by resolving diagnostic uncertainty, announced that data demonstrating the cost-effectiveness of the Percepta Bronchial Genomic Classifier were published for the first time today in the Journal of Thoracic Oncology (JTO). These data suggest that use of the Percepta classifier in lung cancer screening and diagnosis can meaningfully reduce invasive procedures and associated costs, and is cost-effective across a range of assumptions.
The Percepta classifier is used to resolve inconclusive bronchoscopy results in patients undergoing evaluation for potentially cancerous lung nodules or lesions. Among the estimated 350,000 patients who undergo such a bronchoscopy each year, up to 70 percent receive results that are inconclusive. This frequently leads to patients undergoing potentially risky, expensive and unnecessary invasive procedures, including transthoracic needle biopsy (TTNB) and surgical lung biopsy (SLB), to obtain a more definitive diagnosis.
"Unnecessary invasive procedures in lung cancer diagnosis can expose patients to procedural risks and discomfort, and create an additional cost burden to the healthcare system," said David Feller-Kopman, M.D., associate professor of medicine at the Johns Hopkins School of Medicine, and lead author on the JTO paper. "Our findings suggest that use of the Percepta classifier can significantly reduce unnecessary procedures in a cost-effective manner, making it a high-value strategy for the diagnostic work-up of patients with possible lung cancer."
To conduct their analysis, Dr. Feller-Kopman and colleagues evaluated data for 101 lung-nodule patients from the multicenter, prospective AEGIS-1 and -2 studies, which investigated the clinical performance of the Percepta classifier. All patients had a pre-test intermediate risk of lung cancer based on clinical factors. Using a commonly accepted health economics framework (a Markov model), they found that use of the Percepta classifier following an inconclusive bronchoscopy reduced invasive procedure rates by 28 percent at one month and 18.3 percent at two years, compared to use of bronchoscopy alone. They also found that the incremental cost-effectiveness ratio (ICER) – the primary metric used in health economics to assess the value of an intervention – was $15,052 per quality-adjusted life years (QALY). According to the authors, ICER values up to $50,000 per QALY are considered "good value."
"These new data underscore the tremendous value that the Percepta classifier brings to patients and the healthcare system by reducing unnecessary invasive procedures in lung cancer screening and diagnosis," said Bonnie Anderson, chief executive officer and chairman of Veracyte. "They also reinforce our commitment to providing genomic tests that answer clear clinical questions and have a direct impact on physicians' patient-care decision making."
The Percepta Bronchial Genomic Classifier is the first genomic test to receive Medicare coverage for improved safety and accuracy in lung cancer screening and diagnosis. The 23-gene classifier identifies patients with lung nodules who are at low risk of cancer following an inconclusive bronchoscopy result, making it possible to monitor these patients with CT scans in lieu of invasive diagnostic procedures. The Percepta classifier's performance is proven in clinical validation studies enrolling more than 1,000 patients, including strong data published in The New England Journal of Medicine. The 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 classifier is performed at Veracyte's CLIA-certified laboratory in South San Francisco, California. For more information, view the Percepta video.
