BOSTON and JERUSALEM, Feb. 25, 2021 (GLOBE NEWSWIRE) -- Entera Bio Ltd. (NASDAQ: ENTX), a leader in the development of orally delivered large molecule therapeutics, announced today the publication of the results of its previously completed Phase 2a study of EB612 in the Journal of Bone and Mineral Research. The article, titled “Safety and Efficacy of Oral Human Parathyroid Hormone (1-34) in Hypoparathyroidism: An Open-Label Study,” discussed the results of the four-month study in which EB612 was evaluated in 2015 as an adjunct to standard calcium and vitamin D supplement treatment in patients with hypoparathyroidism (HypoPT). EB612, an oral human parathyroid hormone (1-34) (PTH), has received Orphan Drug designation from the U.S. Food and Drug Administration and the European Medicines Agency for the treatment of HypoPT.
The Phase 2a study demonstrated the safety and tolerability of EB612 administered four times daily for 16 weeks to patients with HypoPT. The study achieved its primary and secondary endpoints, including a reduction in calcium supplements, reductions in serum phosphate and 24-hour urine calcium excretion, maintenance of albumin-adjusted serum calcium (ACa) within the reference range, and an improvement in quality of life. Specific results of this trial included:
- A significant reduction of 42% (p=0.001) from baseline in median calcium supplement use;
- Maintenance of median ACa levels above the lower target level for HypoPT patients (>7.5 mg/dL) throughout the study;
- A rapid decline of 23% (p=0.0003) in median serum phosphate levels 2 hours following the first dose that was maintained within the normal range for the duration of the study;
- A notable median decrease of 21% (p=0.07) in 24-hour urine calcium excretion between the first and last treatment days; and
- An increase in quality of life score of 5% (p=0.03) from baseline by the end of the treatment period.
In this study, patients were titrated up to a maximum of 12 EB612 0.75 mg tablets a day (total daily dose of 9 mg) by the investigator, according to each subject’s ACa, and supplement treatment regimen. Of the 19 enrolled subjects, 17 completed the trial (of which 15 were per protocol). No drug-related serious adverse events were reported and most of the adverse events were not considered study drug-related.
“The publication of our Phase 2a EB612 study results in this leading peer-reviewed journal support our HypoPT development program and the value of our platform technology. The availability of an oral PTH is expected to improve compliance, as well as therapeutic impact and may offer patients with HypoPT a much-needed alternative to the currently available parathyroid hormone replacement therapy options which are administered via daily injections. We are currently working on improved formulations of EB612 and the design of the next clinical trial which we expect to initiate in 2022,” stated Entera CEO Spiros Jamas. “In addition, through the use of our previously announced at-the-market equity program, we have continued to strengthen our balance sheet in the first quarter of 2021, and we are now funded into the fourth quarter of 2021.”
The full peer-reviewed publication will be available on Entera’s website once the final article is released for publication and can be found here.
About Hypoparathyroidism
Hypoparathyroidism (HypoPT) is a rare condition in which the body produces insufficient amounts of parathyroid hormone. Individuals with HypoPT typically exhibit abnormally low levels of calcium in the blood (hypocalcemia), and high levels of phosphate in the blood (hyperphosphatemia). They also develop increased urine calcium (hypercalciuria). HypoPT is estimated to affect approximately 77,000 individuals in the United States. Historically, the treatments for HypoPT have been calcium supplements and active vitamin D (calcitriol or alfacalcidol). Phosphate binders that inhibit phosphate absorption and thiazide diuretics that reduce urine calcium are occasionally added. It is often difficult to titrate the dose of both calcium supplements and active vitamin D to reduce symptoms of hypocalcemia without producing increased urine calcium or hypercalcemia with tissue calcification during chronic use, which can result in kidney injury and significant healthcare costs. Moreover, the high doses of calcium supplements may produce stomach and gastrointestinal symptoms as well as other symptoms that negatively affect a patient’s quality of life. A once-daily, injectable form of parathyroid hormone has been approved by the FDA and EMA for the treatment of hypocalcemia in patients with HypoPT.
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.
