About ENTX
Entera Bio Ltd is an Israel-based clinical-stage biopharmaceutical company focused on the development and commercialization of orally delivered large molecule therapeutics for use in areas with unmet medical need and where adoption of injectable therapies is limited due to cost, convenience and compliance challenges for patients. The Company developed a platform that enables the oral delivery of injectable proteins and large molecules. Entera Bio candidates are EB613 for the treatment of osteoporosis and EB612 for the treatment of hypoparathyroidism. Both EB613 and EB612 are oral formulations of human parathyroid hormone (1-34), or Parathormon (PTH). The products are administered via injection.

Entera Bio Receives Positive FDA Feedback for EB613 Phase 3 Trial Approval
- Regulatory Breakthrough: Entera Bio announced that the FDA has provided positive feedback on its EB613 registrational Phase 3 trial protocol, marking a significant step in the development of oral osteoporosis treatments, with the potential to become the first oral anabolic therapy in the market.
- Clinical Design Approval: The FDA accepted Entera Bio's proposed design for a randomized, double-blind, placebo-controlled Phase 3 study involving approximately 750 postmenopausal women, with total hip bone mineral density at 12 months as the primary endpoint, laying the groundwork for a future New Drug Application.
- Significant Market Potential: With around 200 million women affected by osteoporosis globally and over 2 million fractures occurring annually in the U.S., Entera Bio's EB613 aims to address the low adoption rates of existing injectable therapies, potentially expanding the patient base significantly.
- Diversified Product Pipeline: In addition to EB613, Entera Bio is advancing multiple oral peptide drugs, including EB612 and EB618, showcasing its robust platform capabilities in oral peptide technology, which enhances the company's competitive position in the market.

Entera Bio's Bone Density Treatment Trial Progress
- FDA Support for New Trial: The U.S. FDA has approved Entera Bio's EB613 for a single large late-stage clinical trial, aiming to enroll approximately 750 postmenopausal women, which is a significant advancement in the treatment of osteoporosis and supports the company's path toward FDA approval.
- Accelerated Timeline: Entera expects to begin the trial in late 2026 and report top-line results in the second half of 2028, about a year earlier than previously planned, which will expedite the product's market entry and enhance its competitive position.
- Significant Early Study Results: The company's earlier mid-stage study involving 161 postmenopausal women demonstrated meaningful increases in bone density at the spine and hip, indicating the potential of EB613 in osteoporosis treatment and likely attracting more patients to its use.
- Market Sentiment Shift: ENTX shares surged 52% following FDA feedback, with retail investor sentiment jumping from 'bullish' to 'extremely bullish', while analysts rated the stock a 'Buy' with a price target of $9, suggesting a potential upside of about 643%, reflecting strong market confidence in the drug.

Entera Bio Reports Preclinical Data for EB612 and EB618
- EB612 Clinical Data: Entera Bio's EB612 demonstrated robust bioavailability and sustained calcium increases across three preclinical models, with an IND application expected by late 2026, marking a significant advancement in treating hypoparathyroidism.
- Good Tolerability: In non-human primate models, a single oral dose of EB612 significantly raised serum calcium levels for three days without safety concerns, laying a solid foundation for its future clinical applications.
- EB618 Efficacy: As the first dual GLP-1/glucagon receptor agonist, EB618 exhibited dose-proportional pharmacokinetics in non-human primates and showed good tolerability even at doses exceeding the anticipated clinical range, supporting its potential in obesity and metabolic disorder treatments.
- Collaborative Development Strategy: Entera's partnership with OPKO Health has expanded, with both companies advancing EB612 on a 50/50 basis, showcasing Entera's strong R&D capabilities and market prospects in the oral peptide drug sector.

Entera Bio Hosts KOL Roundtable on EB613 for Osteoporosis
- Significant Treatment Gap: Approximately two million osteoporotic fractures occur annually in the U.S., and while 92% of gynecologists would prescribe anabolic therapy if an oral option were available, only 12% currently use injectable anabolic agents, highlighting a substantial treatment gap.
- Clinical Potential of EB613: As the first oral anabolic agent, EB613 stimulates bone formation while suppressing bone breakdown, with six-month bone density increments comparable to injectable PTH, potentially transforming the current treatment paradigm.
- Clinical Trial Plans: Entera Bio intends to advance EB613 into Phase 3 trials imminently, designed to evaluate its efficacy both as a monotherapy and in combination with anti-resorptive agents, further validating its application in osteoporosis treatment.
- Increased Patient Acceptance: The oral formulation of EB613 is expected to reduce patient resistance to injectable therapies, significantly enhancing treatment adherence and thereby improving bone health and quality of life.
