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 patients.

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.

Platform technology

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.
