EndoPredict® Test Receives Positive NICE Recommendation for Patients with Early Breast Cancer

NICE Decision is a Major Milestone in Expanding Access to Patients in the UK

SALT LAKE CITY, Dec. 19, 2018 (GLOBE NEWSWIRE) — Myriad Genetics, Inc. (NASDAQ: MYGN), a global leader in personalized medicine, today announced that the United Kingdom’s (UK) National Institute for Health and Care Excellence (NICE) has included EndoPredict^® in its recommendations for guiding adjuvant chemotherapy decisions for people with ER-positive, HER2-negative early breast cancer and who are lymph node-negative.

“I am delighted that NICE has approved the use of EndoPredict to help us decide which breast cancer patients are most likely to benefit from chemotherapy and, equally importantly, which patients can avoid it,” said Mr. Simon Marsh, M.D., FRCS, consultant breast surgeon at Colchester Hospitals University NHS Foundation Trust.  “I would envisage that using EndoPredict will increase the quality of care we can give to our patients with breast cancer and it marks another step along the road to truly personalised cancer treatment.”

After an extensive technical review, NICE concluded that the clinical evidence justifies EndoPredict for patients with intermediate risk of distant recurrence as determined by a validated tool such as PREDICT or the Nottingham Prognostic Index.  The information provided by the EndoPredict test will help patients choose, with their clinician, whether or not to pursue adjuvant chemotherapy.

“We are excited that NICE has acknowledged the clinical benefits of the EndoPredict test for people with early breast cancer,” said Ralf Kronenwett, M.D., Ph.D., director of International Medical Affairs, Myriad Genetics.  “The NICE recommendation is the result of years of hard work and research by many people to advance cancer care for patients in the UK.”

Earlier this month, Myriad presented important new data at the San Antonio Breast Cancer Symposium (SABCS) which demonstrated that EndoPredict is the only test to answer three critical questions for patients: risk of breast cancer recurrence, benefits of chemotherapy and risk of late metastasis to identify patients who can safely avoid extended endocrine therapy.  Additionally, academic researchers from the Technical University of Munich presented new prospective outcomes data at SABCS.  The key finding is that patients with a high EndoPredict test score had a better outcome with adjuvant chemotherapy compared to endocrine therapy alone.

About Breast Cancer in the United Kingdom
According to Cancer Research UK, 1 in 8 women are still predicted to get breast cancer at some point in their lives.  There are approximately 55,000 new cases of breast cancer diagnosed in the UK each year.  Of those, it is estimated that approximately 14,000 patients per year are diagnosed with intermediate risk for distant recurrence.

About EndoPredict^®
EndoPredict is a third-generation, multigene prognostic test that combines genetic information from the tumor with important clinical features to help clinicians personalize treatment plans for patients with early-stage breast cancer.  EndoPredict has been validated in approximately 4,000 patients with node-negative and node-positive disease and has been used clinically in more than 25,000 patients.  In contrast to first-generation multigene prognostic tests, EndoPredict is validated to accurately predict both early (0-5) and late (5-15 years) distant recurrence and for prediction of benefit from both adjuvant chemotherapy as well as which patients can safely forgo extended endocrine therapy beyond five years.  EndoPredict is manufactured by Myriad Genetics, Inc.
