JERUSALEM, April 03, 2023 (GLOBE NEWSWIRE) — Entera Bio Ltd. (NASDAQ: ENTX) ("Entera" or the "Company") a leader in the development of orally delivered peptides and therapeutic proteins, today announced feedback from its Type D Meeting with the U.S. Food and Drug Administration (FDA) related to EB613's [daily oral hPTH(1–34), teriparatide, tablets] proposed registrational program for the treatment of postmenopausal women with osteoporosis. Entera submitted a draft phase 3 study protocol and requested the FDA's written responses to two questions.

On the first question, "Based on the FDA's feedback provided in the Type C meeting written response August 19, 2022, and subsequent teleconference held on September 27, 2022, the Sponsor has updated the Phase 3 protocol design including the use of Total Hip Bone Mineral Density (BMD) as the primary endpoint. Does the FDA concur that the revised protocol meets its expectations?" the FDA responded that it is not opposed to the use of BMD as a surrogate for fracture, including initiating a study under the proposed Foundation for the National Institutes of Health Bone Quality Project (FNIH BQP)¹ pathway, which is undergoing review. The FNIH–BQP approach to BMD as a surrogate endpoint for fracture was first discussed with Entera during its End of Phase 2 Meeting with the FDA (as announced in July 2022). In the Type D meeting responses, the FDA confirmed to Entera that a 24–month placebo–controlled phase 3 trial with the primary efficacy analysis at 24 months is acceptable and provided some guidance on the statistical evaluation of the study.

On the second question, "Does FDA agree that the design of the population PK (pharmacokinetic) and exposure response evaluation incorporated in the draft Phase 3 study protocol meets FDA expectations?" FDA responded that the Company's proposed PK sampling scheme in the phase 3 study seems reasonable.

"We thank the FDA for our Type D Meeting and their ongoing support for our EB613 program. We are very pleased that the agency has re–affirmed its acceptance of BMD as an endpoint and our placebo–controlled design. We will continue our dialogue with the FDA and we will be ready to initiate our study once the FDA provides us with final guidance on their review of the FNIH–BQP. The ethical concerns associated with placebo–controlled fracture endpoint studies in osteoporotic patients at high risk of fracture is a critical barrier to new drug development for this common disorder. Entera is proud to be part of this incredibly significant process with FDA, which is also sponsored by the ASBMR. Our conviction that EB613, as the first potential oral osteoanabolic treatment, may help millions of women globally is unwavering; and we look forward to initiating our pivotal Phase 3 study under this critical initiative. Meanwhile, we are preparing to start the PK study for our next generation platform, which may enable us to advance our EB612 program for the treatment of hypoparathyroidism into Phase 2 in 2024," stated Miranda Toledano, Chief Executive Officer of Entera.

About Entera Bio

Entera is a leader in the development of orally delivered macromolecules, including peptides and other therapeutic proteins. The Company focuses on significant unmet medical needs where a daily mini tablet form of a peptide treatment or replacement therapy holds the potential to transform the standard of care. The Company's most advanced product candidates, EB613 for the treatment of high risk, post–menopausal osteoporosis and EB612 for the treatment of hypoparathyroidism, are in clinical development. EB613 is the first oral, once daily mini tablet presentation of synthetic hPTH (1–34), (teriparatide), consisting of the exact same 34 amino acid sequence as daily subcutaneous teriparatide injection, Forteo , which requires daily SC injections. A placebo controlled, dose ranging Phase 2 study of EB613 tablets (n= 161) met primary (PD/biomarker) and secondary endpoints (BMD) in a dose dependent manner and was presented at the ASBMR 2021 Annual Conference. A phase 1 PK study of novel PTH formulations is planned for H1 2023 to ascertain feasibility of a new hypo candidate (a prior formulation had positive Phase 2a data announced in 2015 and published in JBMR 2019) and for another potential indication.
