Biocept announced that new data show the company’s cerebrospinal fluid assay, CNSide™, detected tumor cells and identified actionable mutations in lung cancer patients with leptomeningeal carcinomatosis, allowing for targeted treatment decisions that may improve outcomes and extend life expectancy. The study will be presented as a poster at the Third Annual Conference on Brain Metastases hosted by the Society for Neuro-Oncology (SNO), being held virtually Aug. 19-20, 2021. More than 198,000 patients are diagnosed with non-small cell lung cancer (NSCLC) each year. An estimated 3-9% of those patients will develop leptomeningeal carcinomatosis (LMC), a complication in which the cancer spreads to the membranes surrounding the brain and spinal cord. LMC is typically diagnosed through clinical evaluation, imaging and cytology, which have limited sensitivity. When left untreated, the average patient life expectancy is just four to six weeks. The retrospective study, conducted at the University of Utah Huntsman Cancer Institute, used Biocept’s CNSide assay to detect and analyze tumor cells in the cerebrospinal fluid of 15 unique patients. Of the samples analyzed, CNSide detected tumor cells in 100% of samples with LMC, while cytology detected tumor cells in just 40% of the samples. CNSide also identified actionable biomarkers in tumor cells, which allowed oncologists to make targeted treatment decisions that reduced debilitating symptoms and extended patient lives by more than three years in some cases. The study results suggest that CNSide is more sensitive than cytology, and survival of patients with LMC can be prolonged if an actionable target is identified and treated.
Biocept, Inc. is a molecular oncology diagnostics company. The Company focuses on developing and commercializing clinical diagnostic laboratory assays designed to identify rare tumor cells and cell-free tumor deoxyribonucleic acid (DNA) from blood and cerebrospinal fluid (CSF). Its product is branded and trademarked under the name CNSide. CNSide encompasses a suite of cellular and molecular technologies intended to aid medical professionals in CSF analysis and central nervous system (CNS) disease management in patients with solid tumors. It offers and conducts its commercialized diagnostic assays, which include cell capture and enumeration, immunocytochemistry, fluorescent in situ hybridization (FISH), and next generation sequencing (NGS). It has commercialized its CNSide assays for detecting and characterizing many different carcinomas and melanoma. These assays utilize its dual cellular and ctDNA technology platforms and provide biomarker analysis from a patientâs CSF sample.
