Announcement
Entera Bio Ltd. announced the presentation of a poster titled "A First-in-Class Oral GLP-2 Analog for Treatment of Short Bowel Syndrome" at the 47th European Society for Clinical Nutrition & Metabolism (ESPEN) Congress in Prague, Czech Republic, highlighting pharmacokinetic (PK) data relating to its oral GLP-2 analog program.
AI Summary
Entera Bio Ltd. announced the presentation of a poster titled “A First-in-Class Oral GLP-2 Analog for Treatment of Short Bowel Syndrome” at the 47th European Society for Clinical Nutrition & Metabolism (ESPEN) Congress in Prague, Czech Republic. The poster highlighted key pharmacokinetic (PK) data for its oral GLP-2 analog program in preclinical studies with OPK-8801003.
In minipig studies, OPK-8801003 demonstrated a plasma half-life of about 15 hours—an 18-fold increase over the injectable therapy teduglutide. After a single oral dose, peak plasma levels (Cmax) reached roughly 200 ng/ml, compared with about 36.8 ng/ml for standard subcutaneous teduglutide in humans.
Systemic exposure (AUC) exceeded 2 h·μg/ml for more than 24 hours, supporting once-daily dosing. No toxicity was observed, indicating a favorable safety profile.
These results suggest the oral GLP-2 tablet could transform treatment for the 30,000 short bowel syndrome patients now dependent on daily injections, offering a less-invasive, personalized therapy option.

EB613 FDA Regulatory Timeline and Events
EB613 is a drug developed by Entera Bio for the following indication: Parathyroid hormone (1-34), or PTH for osteoporosis.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- EB613
- Announced Date:
- September 8, 2025
- Indication:
- Parathyroid hormone (1-34), or PTH for osteoporosis
Announcement
Entera Bio Ltd. 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.
AI Summary
Entera Bio Ltd. will present new results for its oral osteoporosis drug, EB613, at the ASBMR 2025 meeting in Seattle. In a Phase 2 trial of post-menopausal women, daily 2.5 mg EB613 tablets for six months boosted both the spongy (trabecular) and hard (cortical) bone. Using 3D imaging, researchers saw hip bone density rise by up to 2.6% and thickness increase by 1.7% compared to placebo. These improvements suggest EB613 may quickly strengthen bones and reduce fracture risk.
Injectable anabolic treatments help few patients, so EB613’s tablet form could fill an important gap. Preclinical data for a next-generation EB613 tablet showed the same absorption and peak levels in minipigs as the current version. After FDA agreement in July 2025, Entera plans to begin a global Phase 3 registration study for EB613, aiming to make the first daily oral anabolic therapy widely available.

Announcement
Entera Bio Ltd. announced that the Company will present data across three key programs during September 2025.
AI Summary
Entera Bio Ltd. announced it will share new clinical and preclinical data across three key programs in September 2025. These presentations highlight progress toward better oral treatments for bone and gut disorders, as well as an update for investors.
At the American Society for Bone and Mineral Research (ASBMR) meeting, researchers will present Phase 2 results on EB613, an oral PTH(1-34) tablet for osteoporosis. The data show improvements in both trabecular and cortical bone density in postmenopausal women. A second poster will cover next-generation EB613 pharmacokinetics and pharmacodynamics using the company’s N-Tab™ technology.
At the European Society for Clinical Nutrition & Metabolism (ESPEN) Congress, Entera will share PK/PD results for its oral GLP-2 analog targeting short bowel syndrome. Finally, the CEO will give a corporate overview at the H.C. Wainwright Investor Conference in early September.

- Announced Date:
- July 28, 2025
- Indication:
- Parathyroid hormone (1-34), or PTH for osteoporosis
Announcement
Entera Bio Ltd. announced that in a written response to a Type A meeting request, the U.S. Food and Drug Administration (FDA) agreed with the Company's proposal that the NDA marketing application filing for EB613 would be supported by a single multinational, randomized, double-blind, placebo-controlled, 24 month phase 3 study in women with postmenopausal osteoporosis, where change in total hip BMD is evaluated as the primary endpoint, and incidence of new or worsening vertebral fractures is evaluated as the key secondary endpoint.
AI Summary
Entera Bio Ltd. announced that the U.S. Food and Drug Administration agreed to support its plan for EB613’s marketing application. The proposal calls for one multinational, randomized, double-blind, placebo-controlled phase 3 trial in women with postmenopausal osteoporosis, running 24 months.
The primary endpoint will measure the change in total hip bone mineral density (BMD). The key secondary endpoint will track new or worsening vertebral fractures. This design marks a shift from past trials that used fracture rates as the main measure.
Miranda Toledano, Entera’s CEO, said the FDA’s agreement is a major milestone that reflects strong data and collaboration. It lets the company move forward without waiting for formal qualification of bone density as a regulatory endpoint.
EB613 is being developed as the first oral, once-daily anabolic tablet to build bone mass, improve bone structure, and reduce fracture risk in women with osteoporosis.
