Epic Sciences to Present New Data Demonstrating Expanded Clinical Utility of Circulating Tumor Cell (CTC) Count at 2021 ASCO Genitourinary (GU) Cancers Symposium

Epic Sciences, Inc. announced today it will present two abstracts at the 2021 American Society of Clinical Oncology Genitourinary Cancers Symposium virtual meeting on February 11 – 13, 2021. The abstracts feature analysis on the prognostic and predictive value of CTC enumeration in men with progressing mCRPC starting a standard-of-care therapy.

The first abstract presents data on CTC enumeration prior to treatment. “The primary focus of this analysis was to clinically validate CTC number, defined as any cytokeratin positive CD45 negative epithelial cell, enumerated on the Epic Sciences platform, as a prognostic biomarker in men with progressing mCRPC being treated with abiraterone or enzalutamide. Further, we also observed that, using this base definition, CTC count showed strong correlation and comparable associations with overall survival and progression free survival to counts determined using the FDA-cleared CellSearch® predicate device in time-matched samples” said Howard Scher, MD FASCO at Memorial Sloan Kettering Cancer Center.

The second abstract presents the pre-planned CTC biomarker analysis portion of the phase IV CARD trial which randomized cabazitaxel versus AR-signaling inhibitors in 3rd line mCRPC patients.  Professor Johann de Bono at The Institute of Cancer Research, London and lead author of the study commented “We observed that CTC counts pre-treatment were independently prognostic and that patients who maintained low counts at 3-weeks on-therapy had longer survival and a higher rate of RECIST response.”

Epic has demonstrated its expertise in the development of blood-based biopsies that predict therapy response with the launch of the Oncotype DX AR-V7 Nucleus Detect® test, commercially available and reimbursed by Medicare. That test assists physicians in choosing between androgen-receptor-directed therapies and taxane chemotherapy and is offered in the U.S. through Exact Sciences.

Following are the details for the two poster sessions:
