ENTERA BIO ISSUES LETTER TO SHAREHOLDERS
BOSTON, Massachusetts & JERUSALEM,
Israel (January 11, 2021) – Entera Bio Ltd. (NASDAQ: ENTX), a leader in the development of orally delivered large molecule therapeutics, today issued a
Letter to Shareholders from Spiros Jamas, Sc.D its newly appointed Chief Executive Officer and a member of its Board of Directors.
We hope you and your family have fared well and been healthy during a difficult 2020. As we begin the new year, we are hopeful the
global community, with a little help from the biopharmaceutical industry, will overcome the most significant pandemic in a century. Personally, I am thrilled to start 2021 leading Entera and its highly promising oral protein drug delivery platform
through advanced clinical trials with the hope of giving patients a much-needed oral alternative to treatments currently delivered via injection. I believe that Entera’s platform can be used to establish multiple partnering opportunities to
generate funding and allow the Company to share in the future value of de-risked assets. Working with the talented team here, there is much we will accomplish together from both a clinical and corporate perspective.
Strong balance sheet to drive business objectives
Entera strengthened its balance sheet at December 31, 2020 to approximately $8.6 million in cash and cash equivalents with the
addition of $3.2 million in proceeds raised in the fourth quarter through a previously filed at-the-market equity program. This funds the Company’s clinical programs and operations into the third quarter of 2021. At December 31, 2020, Entera had
21.1 million primary shares outstanding.
EB613 – Oral PTH to treat patients with osteoporosis
We recently completed enrollment in the Israeli Phase 2 clinical trial and received U.S. Food and Drug Administration approval for our
Investigational New Drug (IND) application for our lead program EB613, an orally delivered human parathyroid hormone (1-34) (PTH), for the treatment of osteoporosis.
The FDA’s approval of our IND clears Entera to proceed with our initial planned U.S. clinical trial of EB613, which is positioned as the first potential drug
candidate that could provide a patient friendly, once daily, oral, bone building (anabolic) treatment for osteoporosis patients.
Having announced positive interim bone mineral density (BMD) data in the Phase 2 EB613 study, we anticipate reporting interim
biomarker data; and final biomarker, BMD and safety results; in the first and second quarters of 2021, respectively. Assuming positive final results from the current Phase 2 trial, we plan to advance EB613 into a pivotal Phase 3 trial that could
commence patient enrollment in 2022. Our current plan is to utilize the 505(b)(2) regulatory pathway for EB613 requiring a single pivotal non-inferiority study compared to Forteo®, the leading daily injectable PTH with an estimated $1.4
billion in annual sales.
Today’s osteoporosis market is characterized by high prevalence that is greatly underdiagnosed and undertreated. Only an estimated 5%
of osteoporosis patients, those with severe disease, receive treatment today. As a result, the current global market for injectable PTH, the standard of care for severe osteoporosis, is $4 billion. Based on a recent market analysis, we are highly
encouraged about EB613’s potential to improve the quality of life for many of the estimated 200 million people living with osteoporosis worldwide. If we are able to demonstrate that EB613 is as safe and effective as injectable PTH, we believe we
will increase the market size by offering a more patient friendly, pain-free, and lower cost alternative to currently marketed injectable products and potentially grow the total addressable market to $20 billion by treating all osteoporosis
A vast majority of doctors surveyed in the U.S., Europe, and Japan indicated oral PTH would be their preferred method of treatment for
severe osteoporosis patients relative to other options. Moreover, they indicated they would likely increase prescribing levels for osteoporosis patients if an effective oral PTH treatment is available. Data from the market analysis show the
potential of EB613 to have a transformative impact on the treatment of osteoporosis by serving as a possible first line therapy that enables doctors to treat patients with moderate to severe osteoporosis who are currently untreated due to the
constraints associated with injectable PTH.
Beyond the convenience of oral administration and the elimination of pain associated with needles, EB613 also delivers a cost
advantage that may be particularly important to insurers and patients alike. Entera has refined its scalable drug production process, reducing the cost per pill to enable a price point considerably lower than currently marketed injectable products.
Oral PTH to treat hypoparathyroidism, an orphan disease
EB612, an oral PTH for the treatment of hypoparathyroidism, successfully met the primary and secondary endpoints in a Phase 2a
clinical trial. Hypoparathyroidism, for which EB612 was granted orphan drug designation in the U.S. and Europe, is a rare condition in which a person produces an abnormally low level of PTH, causing a heavy disease burden due to its impact on a
patient’s cardiovascular, neurologic, renal, and skeletal systems. There is a clear unmet medical need for a safe and effective treatment for the estimated 60,000 insured hypoparathyroidism patients in the U.S., as Natpara®, the one drug
currently approved by the FDA for this indication was recalled in 2019 and has only recently been reintroduced to a limited number of those patients due to supply issues. Furthermore, this drug is likely to be used in only the most severe patients
due to its potential risk of bone cancer in animal studies.
We believe our platform technology has the potential for use in approximately one third of all large molecule therapeutics. Our
platform involves the simulation of the pharmacokinetic profile of target molecules, the development of specific formulations using our proprietary 2-component system and subsequent confirmation of activity in preclinical studies. Our product
candidates, EB613 and EB612, serve as the initial validation of the platform and we are evaluating additional research programs that have potential applications in a number of indications that are either currently treated via injectables or
untreated. Additionally, our highly productive collaboration with Amgen involving an undisclosed anti-inflammatory target is continuing and Amgen has completed several studies to evaluate different formulations of its drug using Entera’s technology.
As a substantial percentage of FDA approved drugs each year are injectable biologics, we see a significant opportunity for Entera’s
platform technology to deliver these approved products in oral form. While we work to execute on these opportunities, I look forward to a highly productive year with frequent communications with our shareholders. We thank all of you for your
ongoing support of Entera as we continue our focused pursuit to improve patients’ lives. We wish you a healthy, prosperous, and happy 2021.

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 Phase 2 clinical development. Entera also
licenses its technology to biopharmaceutical companies for use with their proprietary compounds and, to date, has established a collaboration with Amgen Inc. For more information on Entera Bio, visit www.enterabio.com.
