Press Release

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)-- Veracyte, Inc. (NASDAQ: VCYT) today announced that data from five studies validating the performance of the next-generation Afirma^® Genomic Sequencing Classifier (GSC) in thyroid cancer diagnosis will be presented at the 87^th Annual Meeting of the American Thyroid Association (ATA) being held October 18-22 in Victoria, BC, Canada. Two oral and three poster presentations will demonstrate the Afirma GSC's ability to further reduce unnecessary surgeries in thyroid cancer diagnosis while providing physicians information to enable more appropriate treatment when suspicious nodules are identified.

"We believe the results of these studies highlight the Afirma GSC's unique ability to provide physicians with answers, including answers to the most challenging biological questions, as they evaluate patients for thyroid cancer," said Bonnie Anderson, Veracyte's chairman and chief executive officer. "These data reinforce our commitment to develop the extensive clinical evidence required to gain both physicians' and patients' confidence in using our genomic tests to inform important patient-care decisions."

Data from two studies evaluating the Afirma GSC's performance in two of the most challenging thyroid biologies will be shared as oral presentations at the ATA meeting:

About Afirma

The Afirma Genomic Sequencing Classifier is the next-generation version of the Afirma Gene Expression Classifier, and 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.
