Earlier this month, Cernostics received notification from the European Patent Office that claims will be issued for its patent entitled "Systems and Compositions for Diagnosing Barrett’s Esophagus and Methods for Using the Same." This notice comes on the heels of a recent issuance of a corresponding U.S. patent (U.S. Patent No. 10,018,631).
Cernostics’ recent patent claims relate to the company’s clinical test for predicting disease progression in patients with BE and assessment of the likelihood that BE may further develop into esophageal adenocarcinoma (EAC). The patents support a multiplexed evaluation of how protein biomarkers are expressed in various gastrointestinal tissue specimens obtained from BE patients.
Cernostics’ CEO, Mike Hoerres, says, "Our TissueCypher Barrett’s Esophagus Assay was developed as a Laboratory Developed Test for the US market and can be developed as an In Vitro Diagnostic for ex-U.S. markets to assess progression of Barrett’s to esophageal cancer. This technology may help clinicians determine personalized care pathways – establishing which BE patients will likely benefit from endoscopic eradication therapies and what are optimal surveillance intervals for future endoscopies."
About Barrett’s
BE affects more than three million Americans, occurring when chronic exposure to stomach acid causes the esophageal cell lining to deteriorate and undergo changes that can create an environment for cancer. Without treatment, Barrett’s can lead to EAC, with a poor 5-year survival of less than 20%[1]. Today, Barrett’s is commonly managed by surveillance, involving regular endoscopic procedures with biopsy, monitoring disease progression, and GERD-related drug therapy to control symptoms and prevent esophageal injury.
