Biocept Comments on Updated Consensus Medical Guidelines Recommending Liquid Biopsy for Profiling of Tumor Biomarkers to Assist with the Treatment of Patients with Lung Cancer

SAN DIEGO, Jan. 30, 2018 /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, comments on the recently updated consensus clinical guidelines from four major societies considered authorities in pathology and oncology that recommend the use of liquid biopsy testing for patients newly diagnosed with lung cancer as well as those progressing on first-line targeted therapy.

The evidence-based guidelines were developed in collaboration by the College of American Pathologists (CAP), the International Association for the Study of Lung Cancer (IASCL), the Association for Molecular Pathology (AMP) and the American Society for Investigative Pathology (ASIP), and jointly published in the Archives of Pathology & Laboratory Medicine, Journal of Thoracic Oncology and The Journal of Molecular Diagnostics. The published guidelines can be found on the IASLC's website.

"These leading medical associations clearly see that liquid biopsy can be critical for obtaining actionable molecular information to improve treatment outcomes of patients diagnosed with lung cancer," said Veena Singh, M.D., Senior Vice President and Senior Medical Director at Biocept. "We believe the updated medical guidelines are likely to increase the use of liquid biopsy technology by pathologists and oncologists.  This could lead to more patients benefitting from Biocept's assays, which focus specifically on validated actionable biomarkers, offer industry-leading performance, and are reimbursed by many health plans."

Key guideline updates with regard to the use of liquid biopsy include the following:

• Recommendation 16:In some clinical settings in which tissue is limited and/or insufficient for molecular testing, physicians may use a cell-free plasma DNA assay to identify EGFR mutations.
• Expert Consensus Opinion 17:Physicians may use cell-free plasma DNA methods to identify EGFR-T790M mutations in lung adenocarcinoma patients with progression or secondary clinical resistance to EGFR-targeted tyrosine kinase inhibitors; if the plasma result is negative, testing of the tumor sample is recommended.

Michael Nall, Biocept's President and CEO, added, "The promise of liquid biopsy is beginning to be realized broadly, given the ability to use a simple blood sample to access the same information found with an invasive tissue biopsy. Inclusion in the medical guidelines is a major milestone and demonstrates that liquid biopsy truly has potential to become part of standard practice. At Biocept, we believe that our patented and proprietary liquid biopsy technologies used to provide cutting-edge molecular assays offer additional benefits that no one else in the industry can deliver. We intend to focus on these new guidelines to increase adoption of our Target Selector™ platform as oncologists and pathologists make the most appropriate treatment decisions for their patients."
