Entera Bio Presents Positive Effects of EB613 on Both Trabecular and Cortical Bone in Postmenopausal Women with Osteoporosis at ASBMR 2025
EB613 Demonstrates Significant Effects on Both Trabecular and Cortical Bone Compartments After Just 6 Months of Treatment in Phase 2 Study; Cortical Improvements Comparable to Injectable Teriparatide and Abaloparatide
Company Plans to Initiate Global Registrational Phase 3 Study Following July 2025 FDA Concurrence
Entera also Presented Promising Pharmacokinetic Data for Next-Gen EB613 Single Tablet Candidate as Potential Future Franchise Extension
JERUSALEM, Sept. 08, 2025 (GLOBE NEWSWIRE) -- Entera Bio Ltd. (NASDAQ:ENTX), a leader in the development of oral peptides and proteins replacement therapies, today announced data selected for presentation at the American Society for Bone and Mineral Research ("ASBMR") 2025 Annual Meeting in Seattle, Washington, for its lead program EB613 which is in late stage clinical development for post-menopausal women with osteoporosis. It is estimated that 50 percent of women and 20 percent of men over the age of 50 are at risk of a fragility fractures and less than 30% of patients are adequately treated with available medications.
"The data presented at ASBMR this year marks important progress for our EB613 program," said Miranda Toledano, Chief Executive Officer of Entera. "Available injectable anabolic treatments, while efficacious and recommended across medical guidelines, are only accessible to a minority of patients globally. Our EB613 program is being developed to address the treatment chasm in osteoporosis care with a viable anabolic treatment in tablet format for patients to adequately protect their bones."
In the oral presentation titled "Effects of EB613 Tablets [Oral PTH(1-34)] on Trabecular and Cortical Bone Using 3D-DXA: Results from Phase 2 Study," Rachel B. Wagman, MD presented data using 3D-DXA modelling in a post-hoc analysis of EB613 Phase 2 results to look at the treatment's impact on trabecular and cortical bone. After 6 months of treatment, EB613 2.5 mg demonstrated significant increases in both trabecular and cortical bone parameters as compared with placebo. Mechanistically, the findings suggest that bone strengthening, and fracture resistance may occur rapidly with EB613.
"The improvements across multiple parameters, including integral volumetric BMD, cortical thickness, and cortical surface BMD, suggest that there is an early strengthening effect with EB613 and a deterioration with placebo," said Dr. Wagman. "We look forward to studying the safety and efficacy of EB613 in Phase 3."
- Increases in integral volumetric BMD of the TH and FN by 1.7% (p<0.08) and 2.6% (p<0.03), respectively
- Increases in FN trabecular volumetric BMD by 4.4% vs. placebo (p<0.03) and increases in TH trabecular volumetric BMD by 2.8% (p=0.05 vs. baseline, NS compared with placebo)
- Increases in cortical thickness at the TH and FN by 1.3% (p=0.04) and 1.7% (p=0.056), respectively Improvements in cortical surface BMD at the TH and FN by 1.5% and 2.1%, respectively (both p<0.05)
In a poster presentation titled "Advancing Oral Anabolic Treatments for Osteoporosis: Pre-Clinical Data for Next-Gen EB613 Tablet Utilizing N-Tab™ Proprietary Technology," Entera presented preclinical data for its Next-Gen EB613 candidate. In a cross-over pharmacokinetic study in minipigs, a single 1.5 mg Next-Gen EB613 tablet demonstrated comparable PK to the current formulation of EB613, with identical AUClast and Tmax values (1.2 min*ng/ml and 20 min, respectively), and comparable Cmax. A Phase 1 clinical trial of Next-Gen EB613 is planned to begin in late 2025.
About EB613
Substantial evidence supports the efficacy of anabolic treatments over anti-resorptive drugs for lowering fracture risk in osteoporosis patients. However, all available anabolic therapies are administered by subcutaneous (SC) injection and used in a minority of eligible patients. EB613 (oral PTH (1-34)), is being developed as the first oral, once-daily anabolic tablet treatment for osteoporosis. EB613 completed a phase 2, 6-month, 161-patient, placebo-controlled study that met all biomarker and BMD endpoints without significant safety concerns in women with postmenopausal osteoporosis or low BMD (JBMR 2024). EB613 produced rapid dose-proportional increases in biochemical markers of bone formation, reductions in markers of bone resorption, and increased lumbar spine, total hip, and femoral neck BMD.
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 on 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), teriparatide), 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). 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 metabolic syndromes; and first oral GLP-2 peptide as an injection-free alternative for patients suffering from rare malabsorption conditions such as short bowel syndrome in collaboration with OPKO Health.
