Lucid Diagnostics , a commercial-stage cancer prevention diagnostics company and subsidiary of PAVmed Inc. (Nasdaq: PAVM), announced it has received a Notice of Allowance from the U.S. Patent and Trademark Office (USPTO) for a key patent application. The patent covers Lucid’s proprietary method using methylation of the cyclin-A1 (CCNA1) gene to detect esophageal precancer and cancer, a core feature of the EsoGuard® Esophageal DNA Test.
“This patent enhances our already strong intellectual property portfolio and provides robust protection for the CCNA1 methylation assay, a critical component of the EsoGuard test,” said Lishan Aklog, M.D., Lucid’s Chairman and CEO. “It validates our strategic focus on the laboratory methods of the assay, a path we will continue to pursue for other components.”
The EsoGuard test applies next-generation sequencing (NGS) technology to assess DNA methylation at 31 sites on two genes—vimentin (VIM) and cyclin-A1 (CCNA1). While VIM methylation had been linked to gastrointestinal neoplasias, the association between CCNA1 methylation and esophageal neoplasia is novel and demonstrates higher specificity for conditions like Barrett’s Esophagus (BE) and esophageal adenocarcinoma.
The technology behind EsoGuard and the EsoCheck® Esophageal Cell Collection Device was developed by faculty from Case Western Reserve University (CWRU) with support from the National Institutes of Health (NIH). Lucid holds exclusive global licensing rights to commercialize the technology, which was transferred from research to market through close collaboration with CWRU.
Lucid focuses on patients with chronic GERD, aiming to prevent esophageal cancer through early detection using noninvasive tools like EsoGuard and EsoCheck.
