Myriad Will Present Three New Hereditary Cancer Studies at the ASCO Annual Meeting

SALT LAKE CITY, June 05, 2016 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ:MYGN), a leader in molecular diagnostics and personalized medicine, today announced that results from three studies with the Myriad myRisk® Hereditary Cancer test will be featured in podium presentations at the 2016 American Society of Clinical Oncology annual meeting. These presentations demonstrate the expanding benefits of gene panel testing and underscore the need for gene panel testing to become the standard-of-care for hereditary cancer risk evaluation.

“We’re very excited to have several podium presentations that feature the myRisk Hereditary Cancer test and advance the state-of-the-art of hereditary cancer testing and risk assessment,” said Johnathan Lancaster, M.D., Ph.D., chief medical officer, Myriad Genetic Laboratories. “There are three important findings at this year’s meeting. First, the myRisk test identified a significant number of deleterious mutations that would otherwise have been missed by syndrome-directed testing. Second, among patients with suspected hereditary colon cancer, myRisk identified twice as many deleterious mutations in non-Lynch Syndrome genes as in Lynch genes. Third, the use of the myRisk test did not result in inappropriate patient care or increased distress among patients with an uncertain or negative test result.”

The results of the studies to be presented are described below and abstracts are available at: abstracts.asco.org. Follow Myriad on Twitter via @MyriadGenetics to stay informed about news and updates from the Company.

myRisk Hereditary Cancer Podium Presentations
Title: Yield of multiplex panel testing exceeds expert opinion and validated prediction models.
Presenter: Gregory Idos, Stanford University Cancer Institute.
Date: Sunday, June 5, 2016, 9:45 - 9:57 a.m.
Location: S404, Abstract 1509.

This study evaluated the diagnostic yield and clinical utility of panel testing using the myRisk Hereditary Cancer test in 1,000 patients undergoing hereditary cancer-risk assessment. Before testing, differential diagnoses (DDx) were generated after clinical genetics assessment. After testing, the results showed that 11.6 percent of patients tested positive for a deleterious mutation. The most frequently identified mutations were in BRCA1 (18 percent) and BRCA2 (18 percent), MUTYH (17 percent), APC (7 percent), CHEK2 (6 percent) and ATM (5 percent). Importantly, 70 percent of the mutations were included in the DDx before testing. However, 26 percent of the deleterious mutations were not clinically suspected before testing, which demonstrates the value of gene panel testing in hereditary cancer risk assessment.

Title: Safety of multiplex gene testing for inherited cancer risk: interim analysis of a clinical trial.
Presenter: Allison Kurian, Stanford University Cancer Institute.
Date: Tuesday, June 7, 2016, 8:36 - 8:48 a.m.
Location: S102, Abstract: 1503.

This study evaluated the safety of gene panel testing among patients who were undergoing cancer-risk assessment. The interim analysis of the first 1,000 patients found that 11.6 percent had a deleterious mutation in a cancer susceptibility gene. Overall, self-reported surgery rates were low and there was no difference between patients who had a deleterious mutation and those with a variant of uncertain significance (VUS). Most patients never/rarely had thoughts of cancer affecting their daily activities, did not regret testing and wanted to know the results. Patients with a deleterious mutation reported higher distress and uncertainty scores than those with a VUS or negative result. There was no difference in distress or uncertainty among patients with a VUS or negative result. Based on these findings, gene panel testing did not result in inappropriate medical management or increased distress/uncertainty among VUS and negative patients.

Title: Prevalence of germline mutations in cancer risk genes among unselected colorectal cancer (CRC) patients (pts).
Presenter: Matthew Yurgelun, Dana-Farber Cancer Institute.
Date: Tuesday, June 7, 2016, 8:12 - 8:24 a.m.
Location: S102, Abstract: 1501.

This study evaluated the prevalence of deleterious mutations in 1,100 patients with colorectal cancer (CRC) who were treated at the Dana-Farber Cancer Institute. The results showed that 10 percent of patients had a deleterious mutation: 3.1 percent in Lynch Syndrome (LS) genes and 7.1 percent in non-LS genes. Importantly, only 35 percent of high-penetrance non-Lynch mutation carriers had clinical histories suggesting their syndrome. Patients with non-LS mutations were more likely to have more than one CRC, family history of ovarian cancer, and somatic KRAS G12C mutations relative to patients with no deleterious mutations.
