Veracyte Also Previews Next-Generation Afirma GEC

SOUTH SAN FRANCISCO, Calif., April 3, 2017 /PRNewswire/ -- Veracyte, Inc. (NASDAQ: VCYT), a genomic diagnostics company

focused on reducing unnecessary surgeries and healthcare costs by resolving diagnostic uncertainty, today announced that multiple studies supporting the use of the company's Afirma Gene Expression Classifier (GEC) in thyroid cancer diagnosis were presented by external researchers at ENDO 2017, the annual conference of The Endocrine Society, taking place April 1-4 in Orlando, Florida.

In one study, researchers found that use of the Afirma GEC supports current recommendations for managing patients with thyroid nodules designated as "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP). This relatively recent pathology designation is intended to consolidate a group of thyroid tumors that have a good outcome provided they are surgically removed. Using a comprehensive bio-repository of thyroid nodule samples with paired cytology, genomic testing and histopathology results, the authors found that the Afirma GEC pre-operatively identified 24 of 25, or 96 percent, of nodules that turned out to be NIFTP as "suspicious." This designation helps physicians guide patients with "suspicious" Afirma GEC results to surgery.

"NIFTP is a biologically indolent lesion, yet its diagnosis and distinction from malignant tumors still requires surgical excision, and use of the Afirma GEC reinforces this approach," said Peter M. Sadow, M.D., Ph.D., an associate professor of pathology at Harvard Medical School and director of head and neck pathology at Massachusetts General Hospital and Massachusetts Eye and Ear Infirmary. Dr. Sadow presented the findings in a poster at the meeting.

Other Afirma GEC-related data presented at the ENDO 2017 conference included a poster showing a significant overall discordance (15%) between local pathologists and a central, expert panel in assigning a diagnosis of benign or malignant on surgically resected thyroid nodules. The findings reinforce the challenges in thyroid nodule diagnosis when cytology results are indeterminate and point to the role of genomic testing in enabling a more accurate diagnosis earlier in the clinical pathway, before surgery is performed. Additionally, researchers from the University of Nebraska reported in an oral presentation that use of the Afirma GEC during a five-year period led to a significant reduction (32.2%) in surgery for indeterminate nodules.

Veracyte also previewed an enhanced version of its Afirma Gene Expression Classifier (GEC) in a Product Theater event featuring presentations by Giulia C. Kennedy, Ph.D., the company's chief scientific officer, Richard T. Kloos, M.D., senior medical director – endocrinology, and leading external researchers. The next-generation Afirma GEC will incorporate significantly more genomic information on a single RNA-sequencing platform to further increase the number of patients who can potentially avoid unnecessary thyroid surgery. The company plans to begin making the test available to physicians later this year.

"The evidence presented at the ENDO conference further underscores the value that the Afirma GEC is delivering to thyroid patients, physicians and the healthcare system," said Bonnie Anderson, Veracyte's chief executive officer and chairman of the board. "We believe our enhanced Afirma GEC will enable us to uniquely combine comprehensive RNA sequencing data and machine learning to push the boundaries of what is possible in genomic diagnostics and help even more patients avoid unnecessary thyroid surgery."

About the Afirma GECThe Afirma GEC is used to identify patients with benign thyroid nodules among those with indeterminate cytopathology results in order to preserve the thyroid. Each year in the United States, more than 525,000 fine needle aspiration biopsies are performed to assess patients with potentially cancerous thyroid nodules. Up to 30 percent of the results are indeterminate (not clearly benign or malignant) and physicians have traditionally recommended thyroid surgery for a more definitive diagnosis. Following surgery, however, 70 to 80 percent of patients' nodules are diagnosed as benign, meaning the surgery was unnecessary. Such surgery is invasive, costly and often leads to the need for lifelong daily thyroid hormone replacement drugs.
