Entera Bio Presents Positive New Clinical Data from EB613 Phase 2 Trial Demonstrating Significant Bone Density Improvements in Early Postmenopausal Women
Consistency of BMD gains presented at NAMS 2025 demonstrate EB613’s efficacy in both young postmenopausal women and in women 10 years post-menopause
Data further support EB613 potential as a first-in-class oral anabolic treatment option that could dramatically expand patient access to bone-building therapy
Entera Plans to Initiate Global Registrational Phase 3 Study Following
EB613, Entera’s once-daily oral PTH(1-34) anabolic tablet, is being developed as the first oral bone-building therapy for postmenopausal women at high risk for fracture. Despite clear clinical guidelines recommending anabolic agents for their superior benefits, these therapies remain significantly underutilized due to injectable administration and high costs. In this new analysis of the Phase 2 trial, EB613 demonstrated its effect at the 2.5 mg dose (the regimen selected for the upcoming Phase 3 study) by producing significant and consistent gains in bone mineral density (BMD) at the spine, femoral neck and hip in women within 10 years of menopause, with improvements comparable to those observed in women more than 10 years post-menopause.
"These findings demonstrate that EB613 produces significant BMD improvements in early postmenopausal women, a critical population for fracture prevention," said
Key Findings
In early postmenopausal women (≤10 years since last menstrual period), EB613 (n=8) versus placebo (n=19), statistically significant BMD increases were observed at six months:
- Lumbar spine: 3.1% increase vs placebo at six months (p=0.05), demonstrating significant bone density gains at a key fracture site.
- Total hip: 2.3% increase vs placebo (p=0.03), reflecting meaningful improvements in overall bone strength.
- Femoral neck: 2.0% increase, consistent with gains observed in later postmenopausal women.
These results were comparable to BMD improvements seen in women more than 10 years post-menopause, where EB613 increased femoral neck BMD by 3.2% (p=0.02) and lumbar spine BMD by 2.5% (p=0.08).
“EB613 has the potential to transform how osteoporosis is treated by bringing anabolic therapy into earlier stages of care, where it is rarely used today," said
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 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.
