Prolaris One of Only Two Prognostic Tests Recommended for Expanded Indications

SALT LAKE CITY, March 18, 2020 (GLOBE NEWSWIRE) — Myriad Genetics, Inc. (NASDAQ: MYGN), a global leader in molecular diagnostics and precision medicine, announced that the National Comprehensive Cancer Network (NCCN) updated its professional guidelines for prostate cancer to recommend biomarker-based testing for men with unfavorable intermediate and high-risk disease.  Myriad’s Prolaris test was one of only two prognostic tests for prostate cancer recommended by NCCN for the new expanded indications and is now broadly recommended for use in low, intermediate and high-risk disease.

“NCCN’s endorsement of Prolaris testing in unfavorable intermediate and high-risk disease is a major step forward for men and will help in expanding access to testing,” said Todd D. Cohen, M.D., vice president of Medical Affairs for Urology at Myriad Genetics.  “Recent data demonstrated the ability of Prolaris to determine which men will benefit from multi-modality therapy and who can avoid unnecessary morbidity associated with aggressive treatment.”

In a recent study of 718 men presented at the American Society of Clinical Oncology Genitourinary Cancer Symposium in San Francisco, Myriad demonstrated the ability of Prolaris to predict which prostate cancer patients with unfavorable intermediate or high-risk disease would benefit from additional treatment. In the study, patients above the high-risk threshold saw a statistically significant benefit from multi-modality therapy leading to a reduction in the risk of metastases where patients below the high-risk threshold saw no statistical benefit from additional treatment and could avoid the morbidity associated with increased therapy.

About Prolaris^®
Prolaris is a genetic test developed by Myriad that directly measures tumor cell growth.  The Prolaris test paired with both prostate-specific antigen (PSA) and Gleason provides the level of aggressiveness of a patient’s individual prostate cancer.  PSA and Gleason only have the ability to identify how far the cancer has progressed thus far.  However, when these are combined with a Prolaris test score, patients get an accurate assessment of how aggressively that cancer will progress over the next ten years.
