Entera Bio Ltd.
ENTXBusiness Summary
Entera Bio Ltd. is a clinical-stage company focused on developing first-in-class oral tablet formats of peptides or protein replacement therapies for underserved, chronic medical conditions 1. The company leverages its proprietary N-Tab® platform, designed to stabilize large hydrophilic peptides in the gastrointestinal tract and promote their absorption into the bloodstream 2.
The core business model revolves around the development of oral peptide and protein replacement therapies. The company generates revenue through research services, as evidenced by $42 thousand 3 in revenue for the year ended December 31, 2025, and $181 thousand 4 for the year ended December 31, 2024, attributable to a research services agreement with an external party 5. The company has not yet generated any revenue from product sales 6.
Entera Bio's pipeline includes several differentiated oral peptide programs. The most advanced product candidate is EB613 (oral teriparatide, or oral PTH[1-34]), which is being developed as the first oral, osteoanabolic (bone building) tablet treatment for osteoporosis 7. EB613 is being developed under a 505(b)(2) application to the listed drug, Forteo® (teriparatide SC injection, Eli Lilly) 8. The company has completed a comprehensive nonclinical and clinical package for EB613, including three Phase 1 comparative studies with Forteo® and three Phase 2 clinical studies, with EB613 safely administered to a total of 270 study participants 9. The Phase 2, 6-month, 161-patient, placebo-controlled study met all biomarker and BMD endpoints without significant safety concerns in women with postmenopausal osteoporosis or low BMD 10. At 6 months of treatment, EB613 2.5mg produced comparable total hip BMD increases as those reported for Forteo® at 6 months 11. The company retains global rights to EB613 12.
Another product candidate, EB612, is being developed as the first oral PTH(1-34) tablet peptide replacement therapy for patients with hypoparathyroidism 13. EB612 has been granted orphan drug designation by the FDA and EMA for this indication 14. In December 2025, new in vivo PK/PD data supported the development of a proprietary long-acting PTH (LA-PTH) analog, utilizing the N-Tab® platform, demonstrating a markedly prolonged plasma half-life and sustained elevation of serum calcium levels for more than three days following a single oral administration 15. This supports the development of a once-daily oral PTH tablet for hypoparathyroidism 16. Entera and OPKO each own 50% of the rights related to the LA-PTH hypoparathyroidism EB612 program 17.
The EB618 program focuses on developing the first oral dual agonist GLP-1/Glucagon peptide as a potential once-daily tablet treatment for patients with obesity, metabolic, and fibrotic disorders, also utilizing the N-Tab® platform 18. In September 2024, topline PK/PD results for the OXM program showed significant systemic exposure across two in vivo models, a favorable PK profile, and bioavailability, with high plasma concentrations consistent with semaglutide (Rybelsus®) 19. Oral OXM also showed a statistically significant reduction in plasma glucose levels compared with placebo 20. Under a collaboration and license agreement with OPKO, Entera and OPKO will retain 40% and 60%, respectively, of all proceeds deriving from the Program, and will be responsible for 40% and 60% of the Program’s development costs, respectively 21.
The Oral GLP-2 program aims to develop the first glucagon-like-peptide 2 (GLP-2) peptide tablet alternative for patients suffering from short bowel syndrome (SBS) and other disorders involving mucosal inflammation and nutrient malabsorption 22. In late 2023, a proof of concept single dose pharmacokinetic study in rodents showed oral GLP-2 tablets exhibited significant systemic exposure, with plasma levels approximately 10-fold higher than therapeutic plasma concentrations reported for subcutaneously administered teduglutide (Gattex® label) 23. Pharmacokinetic data from a mini-pig study in September 2025 demonstrated a plasma half-life of approximately 15 hours, supporting once-daily oral dosing 24.
For the fiscal year ended December 31, 2025, the company reported total revenues of $42 thousand 25, with a gross profit of $0 26. Operating expenses totaled $11.529 million 27, leading to an operating loss of $11.529 million 28. Net loss for the year was $11.439 million 29, resulting in a basic and diluted EPS of $0.25 30. Cash and cash equivalents were $7.108 million 31, with restricted cash of $7.775 million 32, and total assets of $15.993 million 33. Total liabilities were $2.892 million 34. The company had an accumulated deficit of $125.4 million 35 as of December 31, 2025.
Comparing 2025 to 2024, revenues decreased by $139 thousand 36, or 77% 37, from $181 thousand 38 in 2024 to $42 thousand 39 in 2025 40. Cost of revenues also decreased by $130 thousand 41, or 76% 42, from $172 thousand 43 in 2024 to $42 thousand 44 in 2025 45. Research and development expenses increased by $1.5 million 46, or 33% 47, from $4.5 million 48 in 2024 to $6.0 million 49 in 2025 50. General and administrative expenses increased by $0.4 million 51, or 8% 52, from $5.1 million 53 in 2024 to $5.5 million 54 in 2025 55. The operating loss increased by $1.944 million 56, or 20% 57, from $9.585 million 58 in 2024 to $11.529 million 59 in 2025 60. Net loss increased by $1.898 million 61, or 20% 62, from $9.541 million 63 in 2024 to $11.439 million 64 in 2025 65. Financial income, net, increased from $58 thousand 66 in 2024 to $90 thousand 67 in 2025 68.
During 2025, Entera Bio issued and sold to OPKO an aggregate of 3,685,226 69 Ordinary Shares for a purchase price of $8.0 million 70 in connection with the 2025 Collaboration Agreement 71. The proceeds of $8.0 million 72 are designated solely to fund development cost obligations under the A&R Collaboration Agreement 73. In February 2026, the company submitted a clinical amendment to the FDA, including the EB613 Phase 3 protocol, statistical analysis plan, and open-label extension synopsis 74.
Business Outlook
Management anticipates that existing cash and cash equivalents will be sufficient to fund ongoing operations through the middle of the third quarter of 2026 75, excluding the initiation of the Phase 3 study for EB613 in osteoporosis 76. The ability to commence the Phase 3 study of EB613 in osteoporosis will require additional funding 77.
A major growth area for Entera Bio is the advancement of EB613 into Phase 3 for the treatment of osteoporosis. Building on FDA alignment in July 2025 and the FDA's December 2025 broad qualification of BMD as a regulatory endpoint for anti-osteoporosis drugs, the company submitted a streamlined Phase 3 protocol to the FDA in February 2026 78. The planned multinational, randomized, double-blind, placebo-controlled Phase 3 study is expected to enroll approximately 750 79 postmenopausal women with osteoporosis and will evaluate the percentage change in total hip BMD from baseline to month 12 as the primary endpoint 80. An open-label extension study is also planned to provide safety and efficacy data for EB613 at 24 months as monotherapy and evaluate the sequence of 12 months of EB613 treatment followed by a standard anti-resorptive drug for an additional 12 months 81. Entera currently retains global rights to EB613 82.
Another significant growth vector is the advancement of a proprietary long-acting PTH (LA-PTH) analog as a once-daily tablet for patients with hypoparathyroidism, as part of a collaboration with OPKO 83. Preclinical findings in 2025 demonstrated a markedly prolonged plasma half-life and sustained elevation of serum calcium levels for more than three days following administration of a single oral tablet 84, supporting once-daily oral dosing 85. The collaboration with OPKO was expanded in February 2026 to jointly advance this LA-PTH program 86. Entera and OPKO each own 50% of the rights related to this program 87, and development expenses through Phase 1 are expected to be funded from the $8 million 88 in proceeds received from OPKO's equity investment in Entera in 2025 89. The company currently expects to submit an IND application to the FDA in late 2026 90.
The company also aims to identify and develop additional high-value oral peptides in collaboration with strategic partners, such as the Oxyntomodulin (Oral GLP-1/Glucagon) and Oral GLP-2 programs 91. In collaboration with OPKO, the company is focusing on developing the first oral OXM, a dual-targeted GLP-1/glucagon peptide, in tablet form for metabolic disorders 92. Entera and OPKO own 40% and 60%, respectively, of the rights related to the OXM EB618 program 93. OPKO is planning to initiate a single ascending dose (SAD) and multiple ascending dose (MAD) Phase 1 clinical study with the subcutaneous injection formulation of OXM, with data expected by the end of 2026 94. Entera plans to file an IND for the oral OXM tablet formulation thereafter 95. For the Oral GLP-2 program, proof of concept has been completed for an oral GLP-2 peptide tablet as an injection-free alternative for patients suffering from rare malabsorption conditions like short bowel syndrome 96.
The company plans to establish select global and regional development and commercial partnerships to diversify and shorten preclinical and clinical development in a capital-efficient manner 97. This includes pursuing research and clinical development partnerships with biopharmaceutical companies with specific domain expertise and those with proven commercial footprints to de-risk late-stage programs 98.
Planned capital allocation includes continued investment in research and development. For the year ended December 31, 2025, research and development expenses were $6.0 million 99, an increase from $4.5 million 100 in 2024 101. This increase was primarily due to $0.7 million 102 in other consulting fees, including regulatory fees for the Type A meeting with the FDA and optimization for the EB613 Phase 3 program, $0.5 million 103 for internal and collaboration programs, $0.4 million 104 in compensation, and $0.1 million 105 in other expenses 106. The company expects research and development expenses to increase significantly in future periods as clinical candidates advance and investments are made in additional preclinical candidates 107.
Risk Factors
Entera Bio faces substantial risks, including significant recurring losses from operations and negative cash flows, leading to substantial doubt about its ability to continue as a going concern 108. The company had an accumulated deficit of $125.4 million 109 as of December 31, 2025 110. Its current cash and cash equivalents of $12.6 million 111 as of March 23, 2026, with $7.8 million 112 designated for the OPKO collaboration, are only sufficient to fund operations through the middle of the third quarter of 2026, excluding the initiation of the EB613 Phase 3 study 113. Additional funding is required for the Phase 3 study and future operations, which may not be available on acceptable terms or at all, potentially leading to delays, curtailment, or cessation of product development 114. All product candidates are in preclinical or clinical development, with no successful completion of development or regulatory approval for any product candidate to date 115. Clinical trials are expensive, time-consuming, and uncertain, with potential for delays, unsatisfactory results, or failure to obtain regulatory approvals 116. The company is also subject to manufacturing risks, as it relies on third parties for clinical and commercial supply, and any issues could increase costs or limit supply 117. Competition from larger pharmaceutical companies with greater resources and existing products for osteoporosis, hypoparathyroidism, and short bowel syndrome could negatively affect commercial opportunities 118. The company is highly dependent on its ability to secure and maintain collaborations for product development and commercialization, and any failure to do so or issues with existing collaborations could adversely affect its business 119. Data privacy regulations, including HIPAA, GDPR, and the Israeli Privacy Protection Law, impose strict requirements, and non-compliance could result in significant fines or reputational harm 120. Global economic conditions, including inflation and geopolitical tensions like the Israel-Hamas conflict, could increase operating costs, disrupt supply chains, and affect the company's ability to raise capital 121. The company's intellectual property, including its N-Tab® platform, is crucial, and failure to establish, maintain, defend, or enforce patent rights could erode competitive advantages 122. Intellectual property litigation is costly and time-consuming, and the company may face claims of infringement from third parties 123.
Management Priorities
Management's message to shareholders emphasizes the company's focus on developing first-in-class oral tablet formats of peptides or protein replacement therapies for underserved, chronic medical conditions, leveraging its N-Tab® platform. They anticipate that existing cash and cash equivalents will be sufficient to fund ongoing operations through the middle of the third quarter of 2026 124, excluding the initiation of the Phase 3 study for EB613 in osteoporosis 125. The company's strategic priorities include advancing EB613 into Phase 3 for osteoporosis, with a planned multinational, randomized, double-blind, placebo-controlled Phase 3 study expected to enroll approximately 750 126 postmenopausal women with osteoporosis 127. Another key priority is advancing a proprietary long-acting PTH (LA-PTH) analog as a once-daily tablet for hypoparathyroidism in collaboration with OPKO, with an IND application to the FDA currently expected in late 2026 128. Finally, management is focused on identifying and developing additional high-value oral peptides in collaboration with strategic partners, such as the Oxyntomodulin (Oral GLP-1/Glucagon) and Oral GLP-2 programs 129.
