  • Further Analysis from PROPHECY Multi-Center Trial
  • Data supports AR-V7 as a prognostic and predictive biomarker
  • Expands clinical utility of CTC-based biomarkers for patient stratification

SAN DIEGO, Calif., February 6, 2020 – Epic Sciences, Inc. announced today it will present two abstracts at the 2020 American Society of Clinical Oncology Genitourinary Cancers Symposium to be held in San Francisco, February 13 – 15, 2020. The abstracts feature two analyses of the PROPHECY trial cohort. One abstract evaluates the androgen-receptor splice variant 7 (AR-V7) in circulating tumor cells (CTCs) as a predictor of resistance to anti-androgen therapy. The second abstract reports new data on CTC-based biomarkers of chromosomal instability and small-cell neuroendocrine transformation and their association to resistance to anti-androgen therapy.

 “This analysis of PROPHECY builds on previous evidence demonstrating AR-V7 as a predictive biomarker, reinforcing the clinical utility of AR-V7 to guide treatment decisions for patients with metastatic prostate cancer and improve patient outcomes,” said Rick Wenstrup, MD, chief medical officer at Epic Sciences. “Further, the research also demonstrated that CTC phenotypes of both chromosomal instability and small-cell neuroendocrine identify AR-V7 negative patients who are resistant to anti-androgen therapy. We believe patient selection strategies based on CTC phenotypes to identify patients more or less likely to respond to the various drug classes in prostate cancer will help in optimizing drug sequencing and associated treatment outcomes for patients.”

Epic demonstrated its expertise in the development of blood-based tests that predict therapy response with the launch of the Oncotype Dx© AR-V7 Nucleus Detect™ test, commercially available and reimbursed by Medicare. The test, which is offered in the U.S. through Epic’s partnership with Exact Sciences for patients with mCRPC, assists physicians in choosing between androgen receptor-directed therapies or taxane chemotherapy.
