BOCA RATON, Fla., May 20, 2024 (GLOBE NEWSWIRE) — Entero Therapeutics, Inc., (NASDAQ: ENTO), (“Entero Therapeutics” or the “Company”), a clinical-stage biopharmaceutical company specializing in the development of targeted, non-systemic therapies for gastrointestinal (GI) diseases, yesterday presented two posters on celiac disease research at the 2024 Digestive Disease Week (DDW 2024) Conference in Washington, D.C. The presentations draw upon research from the robust clinical program investigating latiglutenase, an oral biotherapeutic being developed as a potentially first-in-class, targeted, oral biotherapeutic for celiac disease (CeD). The results from these presentations demonstrate potential for improved CeD diagnostics and clinical trial design.

“These findings will enable us to better monitor celiac disease and refine the tools we use in its diagnosis,” said Jack Syage, Ph.D., President and Chief Scientific Officer of Entero Therapeutics. “The data that indicates significantly higher levels of gluten are required to revert serology to positive in CeD patients underscores a fundamental gap in our diagnostic capabilities. This discovery, combined with the introduction of the VCIEL scale, offers a more nuanced approach to assessing mucosal health, ultimately enhancing the accuracy of our diagnostic criteria and paving the way for more effective targeted therapies.”

“This research is foundational to better understanding the triggers and intestinal damage of celiac disease through a quantitative lens,” stated James Sapirstein, Chief Executive Officer of Entero Therapeutics. “By quantifying the amount of gluten required to elicit an adverse immune response and measuring the underlying tissue alterations that lead to celiac symptoms, we can better design our phase 3 clinical trial and determine what constitutes meaningful change in disease severity in response to latiglutenase, our investigational therapeutic.”

The first presentation, titled, “A Composite Mucosal Scale for Celiac Disease Encompassing both Morphology and Inflammation,” highlights VCIEL, a novel quantitative composite scale, combining the histologic scales of villus height to crypt depth ratio (Vh:Cd) and density of intraepithelial lymphocytes (IEL). As there is currently no broadly accepted measure of mucosal injury, the VCIEL scale is designed to improve the sensitivity and accuracy of indicators measuring small intestinal mucosal health in CeD patients. As described in the poster, the VCIEL scale consistently showed improvements over the individual Vh:Cd and IEL measures across multiple studies, suggesting that VCIEL provides better statistical precision and may be more sensitive to histological changes than the traditional measures.

The second presentation, titled, “Dynamics of Serologic Change to Gluten in Celiac Disease Patients,” details research examining the threshold of gluten intake required to elicit a positive serological response after a period of adherence to a gluten-free diet. Results from the study, which involved the largest database of CeD research, including data from two Phase 2 clinical trials for latiglutenase, determined that a higher gluten exposure level than previously estimated is necessary to induce seropositivity. These findings indicate that the reintroduction of gluten into the diet does not immediately manifest a positive serological response and underscores the potential inadequacy of the gluten quantities traditionally used in diagnosis. The research provides a more precise gauge of how much gluten intake is needed for an accurate diagnosis.

About Latiglutenase
Latiglutenase is an orally administered mixture of two minimally systemically absorbed gluten-specific recombinant proteases being developed as an oral biotherapeutic for celiac disease. It has demonstrated efficacy in alleviating GI symptoms of celiac disease and protecting against intestinal damage in three Phase 2 trials. The Phase 3 clinical development plan for latiglutenase has been reviewed by the GI Division of the U.S. Food and Drug Administration (FDA) at the End of Phase 2 meeting with an agreed plan forward, with initiation of the Phase 3 trials expected in early 2025.

About Celiac Disease
Celiac disease is a chronic, hereditary autoimmune and inflammatory disease triggered by gluten consumption. Celiac disease is characterized by damage to the lining of the small intestine, causing malabsorption, gastrointestinal dysfunction, and debilitating symptoms. Over the course of a lifetime, untreated or poorly managed celiac disease is often associated with deteriorating general health, multiple serious intestinal and extra-intestinal medical complications, and increased morbidity and mortality. Celiac disease is a global disease and affects approximately 1% of the population worldwide and is increasing in prevalence with improved diagnostic tools and improved awareness.

About Digestive Disease Week^®
Digestive Disease Week^® (DDW) is the largest international gathering of physicians, researchers and academics in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery. Jointly sponsored by the American Association for the Study of Liver Diseases (AASLD), the American Gastroenterological Association (AGA), the American Society for Gastrointestinal Endoscopy (ASGE) and the Society for Surgery of the Alimentary Tract (SSAT), DDW is an in-person and online meeting from May 18-21, 2024. The meeting showcases more than 5,600 abstracts and hundreds of lectures on the latest advances in GI research, medicine and technology. More information can be found at www.ddw.org
