Myriad Genetics’s Prolaris Test Significantly Improves The Risk Classification For One Third Of Men Diagnosed With Localized Prostate Cancer

Published: Feb 17, 2017

SALT LAKE CITY, Feb. 17, 2017 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ:MYGN), a global leader in personalized medicine, today announced new data demonstrating the utility of the Prolaris® test to more accurately classify mortality risk and guide the management of newly diagnosed men with prostate cancer. The data are being presented at the 2017 Genitourinary Cancers Symposium (ASCO GU) meeting in Orlando, Fla.

“Myriad is pioneering personalized medicine for prostate cancer and is committed to helping men achieve their treatment goals,” said Michael Brawer, M.D., vice president of Medical Affairs, Myriad Genetic Laboratories. “We are excited about the new data on prostate cancer reclassification being presented at ASCO GU, which adds to the growing body of evidence supporting the Prolaris test and will help urologists to match treatment options with patients’ risk profiles.”

Poster Presentation
Title: Patient NCCN Risk Classification Based on Combined Clinical Cell Cycle Risk (CCR) Score.
Presenter: Steve Stone, Ph.D.
Date: Friday, Feb. 17, 2017: 12:15-1:45 and 6:00-7:00 p.m. ET.
Location: C-17.

This study evaluated the prognostic information provided by the Prolaris test plus CAPRA (i.e., clinical features) to generate an estimate of prostate cancer mortality within 10 years of diagnosis versus NCCN risk category as determined by clinical features alone. The analysis included data from 16,442 men who received the Prolaris test. Based on clinical features alone, men were classified according to NCCN guidelines as low (n=8,695), favorable intermediate (n=3,347), intermediate (n=3,086) or high risk (n=1,224).

After recalculating the risk of prostate cancer mortality using the Prolaris test plus CAPRA, approximately one third of patients were reassigned to a different 10-year mortality risk category. The specific reclassifications by NCCN category were as follows:

  1. Low Risk: 25 percent reclassified to favorable intermediate or intermediate risk.
  2. Favorable Intermediate Risk: 24 percent reclassified to lower and 23 percent to higher risk.
  3. Intermediate Risk: 24 percent reclassified to lower and 25 percent to higher risk.
  4. High Risk: 25 percent reclassified to favorable intermediate or intermediate risk.

“Clinical features alone are useful, but as this study illustrates, and was demonstrated by our numerous prior clinical validation studies, the Prolaris test is a powerful and independent predictor of clinical outcome that can substantially improve the risk classification of newly diagnosed men with prostate cancer,” said Brawer.

About Prolaris ®
Prolaris is a novel 46-gene RNA-expression test that directly measures tumor cell growth characteristics for stratifying the risk of disease-specific mortality in patients with prostate cancer. Prolaris provides a quantitative measure of the RNA expression levels of genes involved in the progression of tumor growth. Low gene expression is associated with a low risk of disease-specific mortality in men who may be candidates for active surveillance and high gene expression is associated with a higher risk of disease-specific mortality in patients who may benefit from additional therapy.
