Biocept Broadens Commercial Focus of its Target Selector Liquid Biopsy Platform to Include Urology Market Segment

Expansion of Biocept's EmpowerTC™ offering now includes predictive and prognostic biomarker testing to aid pathologists and urologists in the management of patients diagnosed with prostate cancer

SAN DIEGO, March 26, 2019 /PRNewswire/ -- Biocept, Inc. (NASDAQ: BIOC), a leading commercial provider of liquid biopsy tests designed to provide physicians with clinically actionable information to improve the outcomes of patients diagnosed with cancer, announces that it will begin commercializing its recently expanded pathology partnership platform, EmpowerTC, to urology and uropathology practices. Biocept has expanded the capability of EmpowerTC to perform biomarker tests that can aid physicians and pathologists in the management of patients diagnosed with prostate cancer. Such tests include the androgen receptor splice variant, AR-V7, PTEN, and other cancer biomarker tests, which can help physicians determine treatment pathways and provide prognostic information with regards to aggressiveness of disease.

"The new uro-oncology biomarkers included in Biocept's EmpowerTC service enables my pathology team to use cutting-edge liquid biopsy technologies, which can be useful in our practice when making treatment decisions for our patients with prostate cancer," said Michael P. Zahalsky, MD, Founder and President of Z Urology in Coral Springs, Florida. "Liquid biopsy testing is becoming an important tool for personalizing cancer treatment, and we look forward to utilizing EmpowerTC to harness predictive and prognostic biomarker information from a simple blood sample."

"We are excited to expand our commercial offering into the urology market segment with the new biomarkers incorporated into our EmpowerTC service," said Michael Nall, President and CEO of Biocept. "We believe that our pathology partnership platform offers urologists and uro-pathologists a unique solution to evaluate and treat their patients diagnosed with prostate cancer, which further distinguishes Biocept from other commercial liquid biopsy services."

About Liquid Biopsy Biomarker Detection for Prostate Cancer

Prostate cancer is a leading cause of cancer death in the United States with 31,620 deaths and 174,650 new cases estimated for 2019.1 The disease is diagnosed from pathologic evaluation (Gleason score) of needle-based tissue biopsies, and biopsy tissue is used to determine prognosis and guide treatment. However, prostate cancer is a multifocal disease and a needle biopsy often misses a potentially relevant tumor; there can also be significant variation within pathologic evaluation of a specific tumor.2,3 Liquid-based biopsy biomarker detection may address tumor heterogeneity and enable more-informed prognosis.

Patients who present with advanced disease typically receive chemical castration with androgen deprivation therapy (ADT) or surgical castration as initial treatment to reduce androgen-driven tumor growth. However, most prostate cancer patients acquire resistance to the initial treatment, thus progressing to a castration-resistant disease state.4 Prognostic markers can help suggest the patient's overall outcome, such as the probability of biochemical recurrence or metastasis, and prognostic markers may be useful to guide patient management. Predictive markers aim to evaluate the likelihood of benefit from a specific clinical intervention.  Liquid biopsy provides the ability to assess both prognostic and predictive biomarkers such as androgen receptor (AR) overexpression, circulating tumor cell (CTC) enumeration, the genomic biomarkers PTEN, MYC, C-met, EGFR amplification and AR splice variant-7 (AR-V7), which offer promise in meeting this important medical need.
