BOSTON and JERUSALEM, March 08, 2022 (GLOBE NEWSWIRE) -- Entera Bio Ltd. (NASDAQ:ENTX), a leader in the development of orally delivered large molecule therapeutics, today announced financial and operating results for the year ended December 31, 2021, and provided an update on its clinical and pre-clinical programs.

2021 and Recent Highlights

• Successful End of Phase 2 Meeting with FDA: Entera met with the U.S. Food and Drug Administration (FDA), presented Phase 2 results, and reviewed the development plan of EB613 including the design of a Phase 3 registration trial expected to commence in 2022. Entera believes that the meeting was positive and confirmed the use of bone mineral density (BMD) as the primary endpoint. The study design is being adjusted to incorporate FDA's input and we intend to maintain close communication with the FDA to support our EB613 Osteoporosis program.
  
  
• Osteoporosis Phase 2 study meets endpoints: Entera effectively executed the clinical development of EB613 for osteoporosis, as the Company's lead drug candidate met its Phase 2 primary and key secondary endpoints. EB613 significantly increased lumbar spine BMD, in addition to the femoral neck, and total hip BMD when compared to placebo after six months of treatment. EB613 demonstrated a safety profile consistent with Forteo^®, a drug that has generated peak worldwide sales of $1.9 billion. Study results were shared with the osteoporosis community in two presentations including being selected for a prestigious Late Breaking Oral Presentation at the American Society for Bone and Mineral Research (ASBMR) Annual Meeting in October 2021.
  
  
• Entera engaged Torreya Capital, LLC, a global investment bank, to serve as their exclusive financial advisor for Entera's business development activities to secure non-dilutive funding through strategic alliances for our lead asset, EB613 for Osteoporosis.
  
  
• EB612 Hypoparathyroidism Successful Phase 2a Data Published, Next Trial Expected to Commence in 2022: Entera's Phase 2a clinical results from its EB612 program, an oral parathyroid hormone (PTH) for the treatment of hypoparathyroidism, were published in February 2021 in the Journal of Bone and Mineral Research. The trial achieved its primary and secondary endpoints with published data showing that when added to the standard of care, EB612 led to a statistically significant decrease in supplemental calcium usage. EB612 has the potential to have a major impact on compliance, adherence, therapeutic impact, and quality of life for patients living with Hypoparathyroidism, a rare condition in which a person produces an abnormally low level of PTH. It also causes a heavy disease burden due to its impact on a patient's cardiovascular, neurologic, renal, and skeletal systems. Entera is currently working on an improved formulation of EB612 and is designing its next clinical trial, which it expects to commence in 2022. EB612 has Orphan Drug status with both the FDA and the European Medicines Agency for Hypoparathyroidism.
  
  
• Advanced Platform Technology: As a leader in the oral delivery of large proteins, Entera further advanced its platform technology in 2021 by identifying potential new treatment indications, filing new patents, and receiving a foundational patent in the European Union, representing new intellectual property with an extended patent life. Entera's platform technology continues to gain recognition for its applications in transforming injectable biologics into oral pills. A study in collaboration with researchers at the University of East Anglia in the UK, describing the platform's dual mechanism of action, was published in the peer-reviewed International Journal of Pharmaceutics: X in October 2021. Additionally, new data were announced¹ suggesting Entera's platform orally delivers human growth hormone, and these data were shared in a poster presentation at the 31st Annual European Pharma Congress in London in 2021.
  
  
• Biopharma Collaborations Continue: While Entera continues its long-term collaboration with Amgen, the Company entered additional new material transfer agreements in 2021 with other companies in the biopharma industry. Working closely with the new collaborators, Entera has been generating proof of principle data on its platform's applications to large molecules, which may lead to additional new deals.
  
  

"We expect multiple milestones in 2022, including commencing patient enrollment in our pivotal Phase 3 EB613 osteoporosis trial, commencing a clinical study to support EB612, and further developing our platform technology for new indications to be advanced in-house and in conjunction with pharma partners," stated Entera CEO, Spiros Jamas, Sc.D. "Heading into our pivotal trial, the prospect of EB613 receiving approval and being available on the market is particularly exciting. We believe our oral bone building product can transform the osteoporosis space by offering a patient-friendly and cost-efficient early treatment to reduce the severity of disease over the long term, potentially leading to improved quality of life. Based on our analysis, EB613 has a multi-billion dollar opportunity to grow the current addressable market by treating patients not on injectables and the 50,000 patients who are on injectables today."

Financial Results for the 12-Months Ended December 31, 2021

Revenues for the twelve months ended December 31, 2021 were $571,000 compared to $365,000 for the twelve months ended December 31, 2020. In this period, the majority of the Company's revenues were attributable to research and development, or R&D, services provided to Amgen under Entera's 2018 collaboration agreement. Cost of revenues for the twelve months ended December 31, 2021 were $373,000 compared to $300,000 for the twelve months ended December 31, 2020, and were primarily attributed to salaries and related expenses in connection with the R&D services provided to Amgen and other material transfer agreements.

Operating expenses for the twelve months ended December 31, 2021 were $12.4 million compared to $11.2 million for the twelve months ended December 31, 2020. Entera's operating loss was $12.2 million for the twelve months ended December 31, 2021, compared to $11.2 million for the twelve months ended December 31, 2020.

Research and development expenses were $6.8 million for the twelve months ended December 31, 2021, compared to $6.4 million for the twelve months ended December 31, 2020, an increase of $0.4 million. The increase was primarily due to an increase in materials and pre-clinical activity as part of the preparation for our Phase 3 clinical trial for EB613.

General and administrative expenses for the twelve months ended December 31, 2021 were $ 5.7 million, compared to $4.9 million for the twelve months ended December 31, 2020. The increase was primarily due to an increase in share-based compensation expenses, D&O insurance costs, and legal expenses.

Net loss was $12.2 million or $0.47 per ordinary share (basic and diluted) for the twelve months ended December 31, 2021, compared to $11.2 million, or $0.67 per ordinary share (basic and diluted) for the twelve months ended December 31, 2020.

At December 31, 2021, Entera had cash and cash equivalents of $24.9 million, compared to $8.6 million at December 31, 2020, and, at March 1, 2022, Entera had $21.7 million in cash and cash equivalents.

Entera expects an operating loss of between $25 and $30 million for the year ending December 31, 2022, and believes its current cash position will be sufficient to fund its operations into the fourth quarter of 2022.

About Entera Bio

Entera is a leader in the development of orally delivered large molecule therapeutics for use in areas with significant unmet medical need where adoption of injectable therapies is limited due to cost, convenience and compliance challenges for patients. The Company's proprietary, oral drug delivery technology is designed to address the technical challenges of poor absorption, high variability, and the inability to deliver large molecules to the targeted location in the body through the use of a synthetic absorption enhancer to facilitate the absorption of large molecules, and protease inhibitors to prevent enzymatic degradation and support delivery to targeted tissues. The Company's most advanced product candidates, EB613 for the treatment of osteoporosis and EB612 for the treatment of hypoparathyroidism are in clinical development. The Company recently completed the phase 2 study for EB613. Entera also licenses its technology to biopharmaceutical companies for use with their proprietary compounds and, to date, has established a collaboration with Amgen Inc.
