Scientific presentations at SABCS15 highlight new data on myRisk Hereditary Cancer test

Data support expanding the role of multi-gene panel testing in breast cancer

Myriad Genetics, Inc.

SALT LAKE CITY, Utah, Dec. 9, 2015 - Myriad Genetics, Inc. (NASDAQ: MYGN), a leader in molecular diagnostics and personalized medicine, today announced it will highlight three scientific presentations related to its myRisk Hereditary Cancer test at the 2015 San Antonio Breast Cancer Symposium (SABCS) in San Antonio, Texas. Data include results from studies that advance the understanding of hereditary cancer testing using multi-gene panels to evaluate patients at risk for or diagnosed with breast cancer.

"Our collaborators will present data at SABCS this year that show multi-gene panel testing with myRisk Hereditary Cancer provides clinically significant results that drive appropriate changes in patient care," said Johnathan Lancaster, M.D., Ph.D., chief medical officer, Myriad Genetic Laboratories. "Importantly, there are new data that demonstrate the positive perceptions from patients after they receive a multi-gene test result. Furthermore, as we expand our testing to broader gene panels and share scientific outcomes from our research collaborations, important new questions are being asked that will expand our thinking about exactly which patients should be tested for hereditary cancer."

myRisk Hereditary Cancer Poster Presentations

  • Title: Interim analysis of multiplex gene panel testing for inherited susceptibility to breast cancer.
    Date: Friday, Dec. 11, 2015: 5:00 to 7:00 p.m. CT.
    Location: Poster Discussion PD7-01.
    Presenter: Dr. Gregory Idos, Stanford University Cancer Institute.

    This multi-center prospective study was designed to analyze data from 2,000 patients undergoing cancer-risk assessment using the myRisk Hereditary Cancer 25-gene panel test. The objective was to determine the benefits of multi-gene panel testing versus traditional genetic testing. The interim analysis of the first 332 patients tested found that 11 percent were positive for a deleterious mutation. Among participants testing negative for BRCA1 and BRCA2 mutations, the myRisk test identified deleterious mutations in 14 patients, representing a 61 percent increase over BRCA testing alone and prompting clinically appropriate risk reduction recommendations and enhanced cancer surveillance. These findings demonstrate the ability of the myRisk Hereditary Cancer test to identify a subset of patients with deleterious mutations who historically would have been missed by traditional genetic testing for BRCA1/2 alone, and who could receive appropriate medical management as a result.

  • Title: The patient experience in a prospective trial of multiple-gene panel testing for cancer risk.
    Date: Thursday, Dec.10, 2015: 7:30 to 9:00 a.m. CT.
    Location: Poster P2-09-07.
    Presenter: Dr. Allison Kurian, Stanford University Cancer Institute

    In this study, 2,000 diverse patients at risk for hereditary breast/ovarian cancer syndrome were evaluated to determine the patient experience following genetic testing with the myRisk Hereditary Cancer test. Patients were surveyed at entry and three months after testing using the Multidimensional Impact of Cancer Risk Assessment (MICRA) scale. An interim analysis of the first 332 patients found that 87 percent said they did not regret learning about the results and 81 percent wanted all their genetic test results for all 25 genes tested. Although the study is ongoing, these interim results suggest there is no evidence of an increase in cancer- or testing-related distress/uncertainty after patients received their test results.

  • Title: Predisposing germline mutations in an unselected academic breast cancer (BC) cohort.
    Date: Wednesday, Dec. 9, 2015: 5:00 to 7:00 p.m. CT.
    Location: Poster P1-08-07.
    Presenter: Dr. Judy Garber, Dana-Farber Cancer Institute

    In this study, 456 patients newly diagnosed with breast cancer were evaluated for mutations in 25 cancer genes using the myRisk Hereditary Cancer test. The results show that 11 percent of the patients in a single academic institution had a germline mutation in a breast cancer predisposition gene. Approximately 7 percent were in BRCA1/2 genes and 4 percent were in other cancer genes. Of the 49 women with deleterious mutations associated with breast cancer, 21 (43 percent) were diagnosed after age 45. This finding suggests that patients diagnosed with breast cancer at older ages may benefit from genetic testing with the myRisk Hereditary Cancer gene panel test.
