EB612, the first long-acting oral PTH peptide replacement tablet for patients with hypoparathyroidism – final variants selected, pre-IND initiatives underway with intention to file IND in late 2026 in partnership with OPKO

EB618, the first Oral OXM (GLP-1/Glucagon) peptide tablet for patients with metabolic syndromes – PK/PD validation complete, intention to file IND pursuant to OPKO Phase 1 SAD/MAD SC injection data

TEL AVIV, March 27, 2026 (GLOBE NEWSWIRE) — Entera Bio Ltd. (NASDAQ: ENTX) (“Entera” or the “Company”), a leader in the development of oral peptides, today reported financial results and key business updates for the year ended December 31, 2025.

“2025 was a landmark year for Entera, our EB613 program and for the osteoporosis community as a whole. We are eager to initiate our important phase 3 study for EB613 and thank the investigator and patient community for their enthusiasm to take part in this mission. While current injectable anabolic or bone forming agents are accepted or accessed by a minority of osteoporosis patients in whom they should be used, our mission with EB613 is to democratize anabolic treatment. EB613 is being developed as the first oral bone building tablet so potentially, every woman and man can have the opportunity to protect their bones whether they are being treated with a primary care practitioner or a specialist,” said Miranda Toledano, Chief Executive Officer of Entera. “Throughout 2025, we also met every milestone relating to our pipeline and advanced each program with the utmost capital efficiency. Our N-Tab® oral peptide platform delivered differentiated preclinical data on LA-PTH, GLP-1/Glucagon and GLP-2 targets in partnership with OPKO Health, Inc. (“OPKO”). We believe these assets will further drive value for patients with hypoparathyroidism, metabolic syndromes and rare gastrointestinal chronic conditions.”

Key Recent Highlights

EB613: First Oral PTH(1-34) Anabolic Tablet for Osteoporosis

• Streamlined Phase 3 Protocol Submitted to FDA: In March 2026, Entera submitted a clinical amendment to the FDA providing a streamlined Phase 3 protocol, statistical analysis plan, and open-label extension synopsis under its IND 505(b)(2) for EB613. The planned Phase 3 trial is a multinational, randomized, double-blind, placebo-controlled safety and efficacy study in 750 postmenopausal women with osteoporosis, with percentage change in total hip bone mineral density (BMD) from baseline to month 12 (rather than month 24) as the primary outcome measure, significantly reducing enrollment requirements and accelerating the potential path to approval. The final single-tablet formulation (Next-Gen EB613) is intended to advance directly into Phase 3, replacing the previous multi-tablet candidate. The Company is still preparing to initiate the study in late 2026, which could translate into topline results in the second half of 2028, approximately one year earlier than previously expected. Entera also submitted a synopsis for a 12-month open-label extension study expected to run in parallel with the NDA review which will provide 12-month, 24-month and sequence data for EB613. FDA feedback is anticipated in late April 2026.
• FDA Alignment on BMD as Primary Endpoint: In July 2025, in a written response to a Type A meeting, the FDA agreed with Entera’s proposal that a single multinational, randomized, double-blind, placebo-controlled, 24-month Phase 3 study where change in total hip BMD is evaluated as the primary endpoint, and incidence of new or worsening vertebral fractures as the key secondary endpoint, would support an NDA marketing application for EB613, making Entera the first company to receive such independent alignment. Following this milestone, in December 2025, the FDA issued a broad qualification of BMD with a suggested context of use that the percentage change from baseline at 24 months in total hip BMD could serve as a validated surrogate efficacy endpoint for novel osteoporosis drug development.
• Next-Gen EB613: Preclinical PK data presented at ASBMR 2026 showed comparable pharmacokinetic exposure of the single tablet to the multitablet EB613 formulation. In late 2025, Entera conducted a Phase 1 safety and PK bridging study of the single tablet versus the multitablet and versus Forteo^®. In early 2026, Entera made the determination to advance the single tablet (the final commercial formulation) to Phase 3 based on its comparability to the multitablet and Forteo^®.
• Strong Phase 2 Data Reinforce Early Onset of EB613 Mechanism of Action to Increase Bone Formation and Decrease Bone Loss: At both IOF and ASBMR 2025 Annual Meetings, EB613 post-hoc 3D-DXA data were selected for oral presentation. The analysis demonstrated significant increases in both trabecular and cortical bone indices after just six months of EB613 treatment, comparable to those reported for injectable teriparatide and abaloparatide. Mechanistically, the findings suggest that bone strengthening and fracture resistance may occur rapidly with EB613.
• Expanded Evidence in Early Postmenopausal Women: At the NAMS 2025 Meeting, new post-hoc Phase 2 analysis showed EB613’s ability to drive significant and consistent gains in BMD at the spine, femoral neck and hip in younger women within 10 years of their last menstrual period and after more than 10 years post-last menstrual period. For younger high-risk women without a prior fracture, BMD is the single most important predictor of osteoporotic fractures.

EB612: First-in-Class Oral Long-Acting PTH(1-34) Replacement Tablet for Hypoparathyroidism

• Positive Preclinical Data Validates Long-Acting PTH Tablet Candidate: In December 2025, Entera announced positive in vivo pharmacokinetic and pharmacodynamic data for proprietary long-acting PTH (LA-PTH) analogs developed by OPKO and formulated with Entera’s N-Tab® platform. In these studies, a single oral tablet achieved a markedly longer plasma half-life compared to unmodified PTH(1-34) controls, with sustained serum calcium elevation for over three days.
• Expanded OPKO Collaboration Accelerates Path to Clinic, Fully Funded Through Phase 1: In February 2026, Entera and OPKO expanded their 2025 collaboration agreement to co-develop the oral LA-PTH tablet for hypoparathyroidism as a priority program, with each party holding a 50% pro-rata ownership interest and sharing development costs equally. The companies have jointly decided to accelerate the program and expect to file an IND application in late 2026. Importantly, Entera’s expenses related to development of the LA-PTH program into Phase 1 are expected to be funded with existing cash on the balance sheet.

EB618: First-in-Class Oral Dual GLP-1/Glucagon (OXM) Tablet for Obesity and Metabolic Disease

• Oral OXM PK/PD Validation Completed; Phase 1 Sequencing Established: Following successful completion of in vivo PK/PD validation for both the subcutaneous and oral formulations of OPK-88006 in 2025, preclinical data presented at ENDO 2025 demonstrated plasma levels consistent with those reported in humans for the highest approved dose of Wegovy® (semaglutide). Entera and OPKO have jointly determined that Phase 1 data from the injectable formulation, expected by year-end 2026, will catalyse the initiation of the oral OXM tablet to Phase 1.

GLP-2 Program for Short Bowel Syndrome 

• PK data presented at ESPEN 2025: The joint Entera-OPKO abstract highlighted a plasma half-life of approximately 15 hours, representing an 18-fold improvement over teduglutide (Gattex®), the only approved GLP-2 therapy for the treatment of short bowel syndrome, which requires a daily injection. The daily GLP-2 tablet candidate could fundamentally change how SBS patients are treated, offering a less-invasive administration that can be titrated to enable personalized dosing in this rare and heterogeneous condition.

Financial Results for the Year Ended December 31, 2025

Cash and cash equivalents were $14.9 million as of December 31, 2025, including $7.8 million in restricted cash designated to fund the OPKO collaboration, inclusive of LA-PTH for hypoparathyroidism (EB612). Cash on hand (not including restricted cash) is expected to support operations through the middle of the third quarter of 2026.

Net loss was $11.4 million, or $0.25 per ordinary share, for the year ended December 31, 2025, compared to $9.5 million, or $0.25 per ordinary share, for the year ended December 31, 2024.

Research and development expenses were $6.0 million for the year ended December 31, 2025, compared to $4.5 million for the same period in 2024, an increase of $1.5 million, primarily reflecting continued regulatory and Phase 3 preparation activities for EB613 and costs related to our internal programs and collaboration programs.

General and administrative expenses for the year December 31, 2025 were $5.5 million as compared to $5.1 million for year ended December 31, 2024, an increase of $0.4 million, primarily due to increase in consultants’ fees and compensation.

Total operating expenses were $11.5 million for the year ended December 31, 2025, compared to $9.6 million for the year ended December 31, 2024.

Net Cash used in operating activities for the year ended December 31, 2025 was $7.4 million.
