Newly Published Data from National Study Supports Interpace Diagnostics’ PancraGEN®

New Article in Peer-Reviewed Journal Highlights Important Role of PancraGEN®   Testing

PARSIPPANY, NJ, Nov. 26, 2018 (GLOBE NEWSWIRE) -- Interpace Diagnostics Group, Inc. (NASDAQ: IDXG) announced today a new scientific paper was published and the primary conclusion showed that DNA analysis using PancraGEN® has a favorable impact on patient outcomes particularly in patients with cysts that have worrisome features supporting more accurate surgery and surveillance decisions. The paper entitled “The Incremental Value of DNA Analysis in Pancreatic Cysts Stratified by Clinical Risk Factors” was published in the November edition of Gastrointestinal Endoscopy, the official peer-reviewed publication of the American Society for Gastrointestinal Endoscopy. The three DNA abnormalities examined in the study, all of which are included in the PancraGEN® assay, included: elevated DNA quantity, KRAS mutation, and loss of heterozygosity (LOH) mutations among a panel of key tumor suppressor genes.

The authors of the article included Dr. James Farrell of Yale University, Dr. Mohammad Al-Haddad of Indiana University, and Dr. Tamas Gonda of Columbia University and the study assessed a total of 478 patients. Of this cohort, 209 had surgical pathology derived outcomes and 269 had clinical follow up of 2 to 8 years. Among patients with worrisome cysts, the presence of multiple DNA abnormalities significantly increased risk of malignancy and the absence of all DNA abnormalities significantly decreased risk to very low levels. Importantly, the absence of all DNA abnormalities deescalated risk in 50% of worrisome cysts, which is consistent with other reports concluding that ancillary DNA testing alters decisions for surgery in 54% of cases in which there are intermediate levels of concern; 79% of such decisions favored observation rather than surgery (Arner DM et al, Endosc Ultrasound 2018;7:29-33).

Jack Stover, President and CEO of Interpace, stated, “This newly published study representing nearly 500 patients authored by these luminaries from such highly respected institutions in a top tier peer reviewed journal provides the most important evidence to date that the use of PancraGEN® can significantly improve outcomes in targeted patient populations.”

About PancraGEN® and PanDNA®

PancraGEN® is a molecular, cancer risk classifier for cysts, solid lesions, and biliary strictures that have potential for pancreatic or bile duct cancer and that by using a small sample of fluid or duct brush, can aid in cancer risk assessment. PancraGEN® is 90% accurate according to clinical studies, enabling effective risk stratification of patients with pancreatic cysts and has been used in over 40,000 cysts since its commercial launch. PancraGEN® utilizes integrated molecular pathology (IMP) which incorporates clinical and imaging data, Carcinoembryonic Antigen (CEA) and Amylase values, and multiple molecular markers evaluated using DNA sequencing. All elements are reviewed my molecular pathologists who assign each case a clinical risk stratification ranging from benign to malignant depending on the aggregate assessment encompassing all of these factors. The Company also now offers a ‘molecular only’ version of PancraGEN® called PanDNA® that only reports the molecular results, enabling clients to conduct their own comprehensive clinical risk assessment based on DNA abnormalities tested by PancraGEN®.
