Myriad Presents Two New Studies at the Western Section of the American Urological Association
New Data Demonstrate the Clinical Performance of the Prolaris® and myRisk® Hereditary Cancer Genetic Tests in Men with Prostate Cancer
SALT LAKE CITY, Nov. 02, 2018 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ: MYGN), a global leader in personalized medicine, today announced new data from two studies presented at the Western Section of the American Urological Association annual meeting in Maui, HI.
The key results are that the Prolaris® test is superior to adverse pathology at predicting the risk of prostate cancer biochemical recurrence after surgery, and the myRisk® Hereditary Cancer test found one in ten men with prostate cancer carry an inherited genetic mutation in a cancer-causing gene.
“Myriad Genetics is committed to advancing personalized medicine and providing urologists with genetic information to enable better care and outcomes for their patients with prostate cancer.” said Todd Cohen, M.D., vice president of Medical Affairs, Myriad Urology. “At this conference, our collaborators presented two new studies that highlight important clinical benefits of the Prolaris and myRisk Hereditary Cancer tests and provide useful information on how these tests can be used to help guide patient care.”
The key data are summarized below.
Title: Biopsy-Derived Cell Cycle Progression Score Outperforms Pathologic Upgrading or Upstaging in Predicting Biochemical Recurrence after Surgery
Poster Presenter: Daniel Canter, M.D., Oshner Health System.
Date: Sunday, Oct. 28, 2018, 7:30 a.m. - 4:30 p.m. HST.
This study compared the Prolaris® test to radical prostatectomy (RP) derived adverse pathology (i.e., upgrading or upstaging) in predicting biochemical recurrence after surgery. The analysis included 557 men with low-risk prostate cancer (Gleason ≤3+4 and clinical stage ≤T2) treated by RP. The Prolaris test score (CCP) was also combined with prostate risk assessment (CAPRA) score to generate a clinical cell-cycle risk score (CCR). Adverse pathology (AP) was defined as upgrading to a post-RP Gleason of ≥4+3 and/or upstaging to post-RP pathological stage ≥T3.
The findings show that the Prolaris test with CAPRA (CCR) was 2.5 times more predictive than adverse pathology in predicting biochemical recurrence after surgery (Chart 1). After accounting for CAPRA, the Prolaris test score (CCP) was >2 times more predictive than adverse pathology (p=0.0008 vs. p=0.018, respectively), confirming that Prolaris provided more prognostic information than AP for predicting surgical failure.

“The findings in this study are novel and appear to indicate that the Prolaris test is a superior predictor of biochemical recurrence compared to the traditional variables associated with adverse pathological features,” said Daniel Canter, M.D., lead investigator and director of Urologic Oncology and Urologic Research at the Oschner Clinic. “Importantly, these results demonstrate the clinical utility of the Prolaris test to help physicians risk stratify men with localized prostate cancer.”
Title: Inherited Germline Mutations in Men with Primary and Secondary Prostate Cancer.
Podium Presenter: Edward Uchio, M.D., University of California.
Date: Friday, November 2, 2018, 8:30 a.m. HST.
This is one of the largest-ever studies to assess hereditary cancer genetic testing for men with prostate cancer. It included 2,609 men who met guidelines for testing and were tested with the myRisk® Hereditary Cancer test from 2013 to 2018. Approximately 75 percent of men had prostate cancer only and 25 percent had prostate cancer plus one other type of cancer.
The results demonstrate that 10 percent of men with prostate cancer were found to carry a pathogenic mutation, and the most common mutations were found in the BRCA1/2, ATM, CHEK2 and the MMR genes. In men who had prostate cancer plus another cancer, the likelihood of having a deleterious mutation increased by 60 percent (p=0.013). Importantly, many of the mutations identified in this study were in genes associated with Hereditary Breast and Ovarian Cancer Syndrome and Lynch Syndrome.
“Our study found that the myRisk Hereditary Cancer gene panel identified mutations in a wide range of clinically significant genes that would be missed using a narrower gene panel that only targeted prostate cancer,” said Edward Uchio, M.D., lead investigator, department of Urology, University of California. “These findings support the clinical use of the more comprehensive myRisk Hereditary Cancer test to achieve the best possible results for patients.”
About Prostate Cancer
According the American Cancer Society, more than 165,000 men will be diagnosed with prostate cancer this year, and there are over 2.9 million men in the United States who have been previously diagnosed with prostate cancer that are alive today.
In February 2018, the National Comprehensive Cancer Network (NCCN) issued new medical guidelines for prostate cancer treatment broadly include biomarker testing in prostate cancer. Importantly, the guidelines include language supporting Prolaris as standard-of-care in treatment decision making for patients with low and favorable-intermediate risk prostate cancer. The NCCN guidelines also support an expansion of hereditary cancer testing for prostate cancer to include all patients with a family history regardless of Gleason score along with all patients with metastatic disease.
Prolaris is a novel 46-gene RNA-expression test that directly measures tumor cell growth characteristics for stratifying the risk of disease progression 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 progression in men who may be candidates for active surveillance and high gene expression is associated with a higher risk of disease progression in patients who may benefit from additional therapy.

About Myriad myRisk® Hereditary Cancer
The Myriad myRisk Hereditary Cancer test uses an extensive number of sophisticated technologies and proprietary algorithms to evaluate 28 clinically significant genes associated with the development of eight hereditary cancers including: breast, colon, ovarian, endometrial, pancreatic, prostate and gastric cancers and melanoma. The myRisk Hereditary Cancer test offers physicians several distinct advantages over other commercial tests, including unsurpassed lab accuracy, industry leading variant classification, a medical management tool and exceptional customer service. Men with prostate cancer can take the Hereditary Cancer Quiz to find out if they might be at risk for an inherited mutation and therefore eligible for myRisk Hereditary Cancer test.
