IRVINE, Calif., Dec. 04, 2024 (GLOBE NEWSWIRE) -- Oncocyte Corp. (NASDAQ: OCX), a diagnostics technology company, today announced the publication of favorable data regarding its DetermaCNI™ assay.
In a paper recently published in the journal Acta Neuropathologica Communications, DetermaCNI showed promise as a liquid biopsy method for diagnosing and profiling central nervous system tumors by measuring somatic copy number aberrations (SCNAs) in cerebrospinal fluid.
For context, copy number instability (CNI) is a scientifically well-known hallmark of cancer. DetermaCNI™ is a patented approach to measuring CNI for the diagnosis and monitoring of cancer. Nearly 300,000 patients in the U.S. each year face primary brain tumors or brain metastasis1. The current standard of care for the confirmation and classification of brain tumors often involves high-risk, highly invasive biopsy of brain tissue. Thus, a liquid biopsy method for diagnosing brain tumors could offer significant benefits over currently available methods, representing a potential $300 million U.S. market opportunity.
Among the study authors were Oncocyte Chief Science Officer Ekke Schuetz and Senior R&D Director Julia Beck.
"This was a proof of principle study to assess whether copy number instability could be measured in the cerebrospinal fluid of patients with brain cancer. The findings suggest that a significant number of the nearly 300,000 patients diagnosed with brain tumors every year in the U.S. could benefit from DetermaCNI,” Dr. Schuetz said. "We congratulate the research team in Frankfurt on the publication of this study in an area of high unmet need.”
As noted in the paper, the gold standard for precise diagnostic classification of brain tumors requires a biopsy, with risks including limited sensitivity and failing to measure the diverse potential regions of the tumor. SCNAs were observed in the cerebrospinal fluid of ten out of the 12 patients with confirmed central nervous system cancers. SCNAs were not observed in any of the 11 patients with benign or unclear central nervous system lesions. The detection of SCNAs is highly specific for tumor-derived cell-free DNA (cfDNA).
Overall, this new study demonstrates DetermaCNI's potential for providing a molecularly informed diagnosis of central nervous system cancers, mapping tumor heterogeneity, tracking tumor evolution, and surveilling tumor patients through a liquid biopsy of cerebrospinal fluid.
Oncocyte believes this study validates the future clinical potential for DetermaCNI, as well as the direction of the company's research and development pipeline, which is designed to drive sustained rapid growth over the next decade. Oncocyte's mission is to democratize access to molecular diagnostic testing to improve patient outcomes. The company is investing in developing products to serve the separate verticals of organ transplant testing and oncology. Oncocyte is presently commercializing its transplant product line, which includes the VitaGraft™ and GraftAssure™ tests. It expects to commercialize its oncology assays over the next two years.
