EsoGuard 2.0 incorporates advanced molecular techniques and leverages improvements in sample DNA yields and processes to enhance assay performance and lower costs
Lucid Diagnostics Investor Day, where Lucid executives, key opinion leaders, and other experts will discuss Lucid's business and technologies, to be held in
"The launch of EsoGuard 2.0 is a seminal milestone for our company and the culmination of over a year of meticulous R&D work by our Chief Scientific Officer, Suman Verma, M.D, Ph.D., and her dedicated and talented team," said Lishan Aklog, M.D., Lucid's Chairman & Chief Executive Officer. "EsoGuard had previously demonstrated unprecedented cancer and precancer detection results, including detecting 100 percent of esophageal cancers and over 80 percent of precancers in a recent study from the National Cancer Institute-funded BETRNet consortium. EsoGuard 2.0 improves upon EsoGuard 1.0's already outstanding performance in multiple respects, including by enhancing DNA yield, streamlining down-stream processes that incorporate advanced molecular techniques and more efficient bioinformatics, and enabling higher-throughput testing. These improvements also lower the per-sample costs of the assay, which we expect to decrease even further in the coming months when we upgrade our NGS-sequencing platform to a higher-throughput model to accommodate increased EsoGuard testing volume. We appreciate the critical input of Sandy Markowitz, M.D., Ph.D., and his colleagues at Case Western Reserve University, the inventors of EsoGuard, in helping us reach this milestone."
The results of the analytical validation studies of the EsoGuard assay, culminating in EsoGuard 2.0, have been accepted for presentation at the upcoming Association of Molecular Pathology Annual Meeting (AMP 2023) on November 18th.
The EsoGuard assay involves first extracting DNA from esophageal cells collected by the EsoCheck® Cell Collection Device. The DNA then undergoes bisulfite conversion, which tags sites which are not methylated. Two genes, VIM and CCNA1, with 31 methylation sites that correlate with esophageal precancer and cancer, are amplified using polymerase chain reaction ("PCR") techniques and then sequenced using next-generation sequencing ("NGS") techniques. Advanced bioinformatics software analyzes the DNA sequence data and determines the proportion of the 31 target sites which are methylated, returning a positive or negative EsoGuard result. The original version of the assay used a singleplex technique, which required the DNA to be split and separately processed for each gene. EsoGuard 2.0 uses multiplexing which allows both genes to be interrogated on a single DNA sample. This breakthrough allows the laboratory to run the assay three times and call positive and negative results by consensus, blunting stochastic noise for low positive samples near the cutoff. The next-generation assay underwent rigorous analytical and clinical validation studies, including head-to-head comparisons of multiplexed triplicate consensus versus singleplex techniques, consistent with CLIA standards. Clinical validation analysis included samples from the ESOGUARD-BE-1 study and demonstrated improved sensitivity and specificity.

About Lucid Diagnostics
Lucid Diagnostics Inc. is a commercial-stage, cancer prevention medical diagnostics company, and subsidiary of PAVmed Inc. (Nasdaq: PAVM). Lucid is focused on the millions of patients with gastroesophageal reflux disease (GERD), also known as chronic heartburn, who are at risk of developing esophageal precancer and cancer. Lucid's EsoGuard® Esophageal DNA Test is performed on samples collected in a brief, noninvasive office procedure with its EsoCheck® Esophageal Cell Collection Device. EsoCheck and EsoGuard are the first and only commercially available tools designed with the goal of preventing cancer and cancer deaths through widespread, early detection of esophageal precancer in at-risk patients.
