Epic Sciences and Genomic Health Announce Favorable Draft Local Coverage Determination (LCD) on Medicare Coverage for Use of the Oncotype DX® AR-V7 Nucleus Detect™ Test in Patients with Metastatic Castration-Resistant Prostate Cancer

SAN DIEGO and REDWOOD CITY, Calif., March 30, 2018 /PRNewswire/ -- Epic Sciences, Inc. (Epic) and Genomic Health, Inc. (Nasdaq: GHDX) announced today that Palmetto GBA, a Medicare Administrative Contractor (MAC) that assesses molecular diagnostic technologies, has issued a draft local coverage determination (LCD) for the Oncotype DX® AR-V7 Nucleus Detect™ test. The draft LCD recommends Medicare coverage for use of the test throughout the United States to help determine which patients with metastatic castration-resistant prostate cancer (mCRPC) may benefit from androgen receptor signaling inhibitor (ARSi) therapy and which may benefit from chemotherapy. The Oncotype DX AR-V7 Nucleus Detect test is a circulating tumor cell (CTC)-based, liquid biopsy test that is commercially available in the United States through Epic's partnership with Genomic Health.

"The Oncotype DX AR-V7 Nucleus Detect test is the first and only predictive and prognostic test in prostate cancer that can identify which patients will no longer benefit from ARSi therapies, such as enzalutamide and abiraterone, and need to switch to chemotherapy or start another type of therapy in order to extend life," said Murali Prahalad, Ph.D., president and CEO of Epic Sciences. "The rapid issuance of the draft LCD recommending Medicare coverage highlights the clinical utility and value of this new test in prolonging survival for men with metastatic castration-resistant prostate cancer."

Prior to the Oncotype DX AR-V7 Nucleus Detect test, there was no clear consensus on therapeutic sequencing after initial exposure to an ARSi therapy, and the most common clinical decision in mCRPC was whether to start a second ARSi or taxane chemotherapy. Detection of AR-V7-positive tumor cells indicates that the patient will no longer benefit from commonly prescribed ARSi therapies but can still benefit from chemotherapy, which has been shown to prolong survival. An estimated 50,000 men in the United States with advanced prostate cancer could benefit from knowing their AR-V7 status prior to selecting further treatment.

Epic's proprietary No Cell Left Behind® technology is delivering a portfolio of blood-based tests predictive of drug response in cancer that are clinically proven, personalized, and focused on improving healthcare economics worldwide.

The draft LCD, posted on the Medicare Coverage Database on the Centers for Medicare and Medicaid Services (CMS) website, will go through Medicare's review process, including a public comment period that started on March 26, followed by finalization and notification. LCDs are subject to annual review by MACs.
