Interpace Biosciences Announces Collaborative Study with University of North Carolina to Assess the Use BarreGEN® after Ablation of Dysplastic Barrett’s Esophagus

Parsippany, NJ, Jan. 06, 2020 (GLOBE NEWSWIRE) -- Interpace Biosciences, Inc. (Nasdaq: IDXG), a leader in enabling personalized medicine, today announced that the Company’s wholly-owned subsidiary, Interpace Diagnostics has entered into a collaborative study aimed at exploring the potential use of BarreGEN® in patients undergoing radiofrequency ablation (RFA). RFA is typically known as a cancer preventative therapy that either delays or arrests the progression of Barrett’s Esophagus to esophageal cancer. Evidence to date suggests that BarreGEN® may identify non-dysplastic Barrett’s Esophagus patients in need of ablation, making targeted ablation a potentially cost-effective treatment option. This new collaborative study performed in partnership with the University of North Carolina Division of Gastroenterology under the direction of Nick Shaheen, MD MPH, using the BarreGEN® assay developed by Interpace aims to target the potential for molecular changes to predict resistance or relapse following RFA.

The study is a prospective, single site study which will be performed using BarreGEN® and targeted to evaluate approximately 60 patients with dysplastic Barrett’s undergoing RFA. Use of BarreGEN® may allow clinicians to adjust ablative protocols providing optimal treatment response and improved patient outcome. The assay may also aid in recognition of patients at risk for recurrence of Barrett’s after initially successful ablation. The study is expected to begin enrolling patients early in the first quarter of 2020 with the hope of readout later in the year.

Historically, BarreGEN® has been evaluated under a Clinical Experience Program (or CEP) and has been used only by patients with non-dysplastic Barrett’s Esophagus to help physicians assess the risk of progression to esophageal cancer to enable optimal management decisions. This new study will evaluate the ability of BarreGEN® results to predict RFA treatment resistance in patients with dysplastic Barrett’s and the need for additional or alternative intervention.

“We look forward to reporting the results of this novel study that will combine Interpace’s molecular expertise in Barrett’s with UNC’s clinical and research expertise” said Jack Stover, CEO of Interpace Biosciences. He continued “We believe this is another important step in bringing our BarreGEN® test more broadly to the market to potentially modify treatment plans that can improve patient outcomes. Defining the value of BarreGEN® in this new patient population may give clinicians a new use for this powerful assay.”

About BarreGEN®

BarreGEN® is a molecular based assay performed on esophageal specimens from patients with Barrett’s esophagus to help assess risk of progression to esophageal cancer. Barrett’s esophagus, often diagnosed in patients with long standing gastroesophageal reflux disease, is a known risk factor for esophageal cancer. BarreGEN® analysis quantifies mutational load providing an indication of cumulative genomic instability. Understanding future risk of progression to esophageal cancer based on genomic changes can help limit unnecessary repeat endoscopies in patients with low risk and justify more aggressive management, such as ablative therapy or surgery, in patients with higher risk.

About Dr. Nicholas Shaheen

Nicholas Shaheen, MD MPH is Chief of the Division of Gastroenterology & Hepatology University of North Carolina School of Medicine, Chapel Hill. As a prominent gastroenterologist and epidemiologist, Dr. Shaheen has been awarded the Bozymski-Heizer Distinguished Professorship at the University of North Carolina School of Medicine. He has authored more than 400 papers and book chapters with focus on pre-cancerous and cancerous conditions of the esophagus, as well as esophageal motility disorders and reflux disease.

Dr. Shaheen is well known for his groundbreaking research on Barrett’s esophagus. A major theme of his research has been developing and testing new endoscopic methods for treatment of patients with Barrett’s. He was the principal investigator of a 19 center U.S. trial of radiofrequency ablation for dysplastic Barrett’s esophagus, demonstrating the efficacy and safety of this procedure. The paper was published in the New England Journal of Medicine. He was also the lead investigator of a 10-center study defining the efficacy of cryotherapy in subjects with Barrett’s and high-grade dysplasia. These endoscopic technologies have fundamentally changed the care of patients with early esophageal neoplasia. He is also a member of several consortia that are conducting translational studies of Barrett’s patients.
