SUFFERN, NY--(Marketwired - April 30, 2014) - CDx Diagnostics today announced that five studies examining the WATS3D biopsy will be presented at Digestive Disease Week 2014 (DDW), taking place from May 3-6, 2014 in Chicago. Among the highlights is a presidential plenary session reviewing results from the largest WATS3D clinical study conducted to date.

The WATS3D biopsy collects a wide area, disaggregated tissue specimen of the entire thickness of the suspect epithelium. This unique tissue specimen is then subjected to specialized, computer-assisted 3-dimensional analysis to pinpoint potentially abnormal cells for presentation to a pathologist. In clinical trials, adjunctive use of WATS3D significantly increased the detection rate of both Barrett's esophagus and esophageal dysplasia. DDW attendees can visit booth # 2711 to learn more about WATS3D.

In addition to the presidential plenary session presentation, other key WATS3D data being presented at DDW include:

  • An oral presentation examining inter-observer agreement among pathologists using WATS3D
  • The first study examining the ability of WATS3D to detect gastric intestinal metaplasia
  • A study examining the benefits of WATS3D in patients with short segment Barrett's esophagus
  • A systematic review and meta-analysis comparing WATS3D to standard endoscopic biopsy alone for detection of Barrett's esophagus and dysplasia

"Our goal is to put esophageal adenocarcinoma on the list of preventable cancers along with cervical cancer, colorectal cancer and skin cancer," said Mark Rutenberg, Chairman and CEO of CDx Diagnostics. "Ten years ago this would have been unthinkable, but new advances in the diagnosis and treatment of the disease are rapidly creating a new paradigm. We believe the data being presented this year at DDW demonstrates the vital role that WATS3D can play in the diagnostic pathway for pre-cancer of the esophagus."

About CDx Diagnostics and the WATS3D Biopsy
CDx Diagnostics' mission is to provide doctors with the most powerful diagnostic technology to help prevent cancer before it can start.

CDx Diagnostics' WATS3D biopsy addresses the sampling error inherent in random forceps biopsy testing of the esophagus. In just a few minutes, gastroenterologists can easily obtain a wide area, full-thickness transepithelial tissue sample for computer-assisted 3D laboratory analysis. In clinical trials, adjunctive use of CDx Diagnostics' WATS3D biopsy significantly increased the detection rate of both Barrett's esophagus and esophageal dysplasia. The high sensitivity of WATS3D is due to the large tissue area sampled, and the proprietary 3-Dimensionial computer imaging system that is based on an algorithm developed as part of the U.S. Strategic Defense Initiative missile defense program.
