OPKO Health and Entera Bio Announce Abstract on PK/PD of Oral GLP-2 Tablet for the Treatment of Short Bowel Syndrome Selected for 2025 ESPEN Congress

MIAMI and JERUSALEM, July 08, 2025 (GLOBE NEWSWIRE) -- OPKO Health, Inc. (NASDAQ: OPK) (“OPKO”) and Entera Bio Ltd. (NASDAQ: ENTX) (“Entera”) today announced that their abstract “First-in-Class Oral GLP-2 Analog for Treatment of Short Bowel Syndrome” has been selected for a poster presentation at the 47^th European Society for Clinical Nutrition & Metabolism (“ESPEN”) Congress, taking place September 13–16, 2025, in Prague, Czech Republic.

Abstract Title: First-in-Class Oral GLP-2 Analog for Treatment of Short Bowel Syndrome

Poster Viewing Date & Time: September 13, 2025, 3:30 - 4:00 p.m. local time & Welcome Reception

Poster Topic: Poster Session 1 - Liver and gastrointestinal tract

Location of Display: Forum Hall Foyer 3

The oral GLP-2 tablet program combines a proprietary long acting GLP-2 agonist developed by OPKO with Entera’s proprietary N-Tab™ technology for patients suffering from short bowel syndrome and additional disorders involving gastrointestinal mucosal inflammation and nutrient malabsorption. Currently, the only approved GLP-2 agonist, which is marketed under the brand GATTEX^® (teduglutide), requires daily subcutaneous injections.

“Given the heterogeneity of patients with SBS and challenging compliance rates attributed to injectable GLP-2 therapy, we believe a daily tablet format may enable more personalized care of this peptide and individualize titration,” said Miranda Toledano, Entera Chief Executive Officer.

About Short Bowel Syndrome

Short bowel syndrome (SBS) is a rare and potentially life-threatening malabsorptive condition caused by a significant loss of functional bowel mass (secondary to congenital defects or disease-associated loss of absorption) or physical bowel mass (secondary to extensive intestinal resection). Approximately 30,000 patients across the US and EU are living with SBS, and current annual sales of GATTEX^® (teduglutide), the only approved therapy for SBS, total roughly $800 million. SBS patients have a reduced ability to absorb nutrients and fluids and are at risk of malnutrition, unintended weight loss and additional symptoms due to the loss of essential vitamins and minerals¹. SBS is the most common cause of chronic intestinal failure, accounting for approximately 75% of chronic intestinal failure cases in adults and 50% of such events in children.²

About Entera Bio

Entera is a clinical stage company focused on developing oral peptide and protein replacement therapies for significant unmet medical needs where an oral tablet form holds the potential to transform the standard of care. The Company leverages a disruptive and proprietary technology platform (N-Tab™) and its pipeline of first-in-class oral peptide programs targeting PTH(1-34), GLP-1 and GLP-2. The Company’s most advanced product candidate, EB613 (oral PTH(1-34)), is being developed as the first oral, osteoanabolic (bone building) once-daily tablet treatment for post-menopausal women with low BMD and high-risk osteoporosis. A placebo controlled, dose ranging Phase 2 study of EB613 tablets (n=161) met primary (PD/bone turnover biomarker) and secondary endpoints (BMD). Entera is preparing to initiate a Phase 3 registrational study for EB613 pursuant to the FDA’s qualification of a quantitative BMD endpoint. The EB612 program is being developed as the first oral PTH(1-34) tablet peptide replacement therapy for hypoparathyroidism. Entera is also developing the first oral oxyntomodulin, a dual targeted GLP1/glucagon peptide, in tablet form for the treatment of obesity; and the first oral GLP-2 peptide tablet as an injection-free alternative for patients suffering from rare malabsorption conditions such as short bowel syndrome in collaboration with OPKO Health.
