On July 11, 2016 Myriad Genetics, Inc. (NASDAQ:MYGN), in collaboration with researchers from the Institute of Cancer Research in London, reported positive results for EndoPredict, a second-generation prognostic gene expression test for breast cancer (Press release, Myriad Genetics, JUL 11, 2016, View Source [SID:1234513812]). The study achieved its primary endpoint by demonstrating that EndoPredict (EPclin) was superior to the first-generation Oncotype DX Breast Recurrence Score (RS) in predicting the long-term recurrence of ER+, HER2- primary breast cancer. The study was published in the Journal of the National Cancer Institute (JNCI).

"This important study demonstrated that EndoPredict more accurately predicted the recurrence of breast cancer up to 10 years after diagnosis in patients with ER+, HER2- breast cancer than the other test studied," said Jack Cuzick, Ph.D., FRS, director of the Wolfson Institute of Preventive Medicine in London, and an investigator of the study. "These findings will help physicians identify patients who do not need adjuvant chemotherapy following surgery, resulting in a more personalized treatment for their patients."

The analysis included 928 women from the TransATAC study and compared the prognostic power of EndoPredict versus the first-generation test. The primary endpoint of the study was distant relapse-free survival. This analysis showed that EndoPredict markedly outperformed Oncotype DX across the 10-year follow-up period with prognostic power more than four times higher (EPclin: LRX2= 139.3; RS: LRX2=29.1). Using pre-defined cutoffs, EndoPredict and Oncotype DX identified 58.8 percent and 61.7 percent of patients as low risk with hazard ratios for low- versus non-low-risk of 5.9 and 2.7, respectively. Importantly, the authors noted that "EPclin’s superior ability to classify patients as low risk was further demonstrated by the similar number of patients classified as low risk by RS coupled with a substantially lower 10-year recurrence rate (5.8% for EPclin vs 10.1% for RS)."

"EndoPredict significantly outperformed the first-generation prognostic test in this head-to-head study, especially for late distant recurrences and in node-positive patients" said Ralf Kronenwett, M.D., chief scientific and medical officer, Sividon. "Additionally, EndoPredict did not classify any patients as intermediate risk, while Oncotype DX classified 28 percent of as intermediate risk which can be confusing for clinicians trying to make treatment decisions."

About EndoPredict
EndoPredict is a next-generation, multigene prognostic test for patients diagnosed with breast cancer. The test provides physicians with information to devise personalized treatment plans for their patients. EndoPredict has been validated in approximately 4,000 patients with node-negative and node-positive cancer and has been used clinically in over 13,000 patients. In contrast to first-generation multigene prognostic tests, EndoPredict detects the likelihood of late metastases (i.e., metastasis formation after more than five years) and, therefore, can guide treatment decisions regarding the need for chemotherapy, as well as extended anti-hormonal therapy. Accordingly, therapy decisions backed by EndoPredict confer a high level of diagnostic safety.
