Entera Bio Provides Business Highlights and Financial Results for the Second Quarter 2022

JERUSALEM, Aug. 11, 2022 (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 its financial and operating results for the quarter ended June 30, 2022.

"We have reset our thesis and executed on several critical milestones in the first half of 2022. On July 18th, we announced the submission of our proposed registrational protocol for EB613 to the U.S. Food and Drug Administration (FDA). We are simultaneously finalizing the validation of an optimized formulation of EB612, while expanding our pre–clinical pipeline with additional anti–inflammatory and metabolic protein candidates. Lastly, we finished the quarter with $17.3 million in cash which, given our revised Phase 3 schedule, is projected to fund our current operations through the first half of 2023," commented Ms. Miranda Toledano, Chief Executive Officer of the Company. "I am incredibly energized by the opportunities ahead. By continuing to carry forward our internal clinical programs and strategic dialogues, we are poised to deliver tremendous value to patients and our shareholders as we reshape the future of Entera. We look forward to providing a comprehensive update to the investment community later this year."

Business Highlights:

Entera expects to hold a Type C Meeting with the FDA to discuss the potential registrational study for its lead clinical asset, EB613 in the second half of 2022. The Phase 3 is designed as an 18 month double blind placebo–controlled study using FNIH–BQP¹ total hip Bone Mineral Density (BMD) thresholds as the primary endpoint to evaluate fracture risk, followed by a 6–month open label transition to alendronate. EB613 is the first oral formulation of PTH (1–34), teriparatide, and the first proposed oral anabolic (bone forming) drug candidate to treat post–menopausal women with osteoporosis. EB613 has the same amino acid sequence as Forteo which requires daily subcutaneous injections and reported peak sales surpassing $1.7 billion in 2017, prior to patent expiry. According to early commercial assessments and clinician surveys, it is estimated that less than 10% of osteoporosis patients use current anabolic drugs (including PTH receptor activators currently available such as Forteo and Tymlos ). Despite the validated mechanism of action of these treatments, patients are deterred by their high cost and injectable mode of administration. As the first oral PTH receptor activator EB613 is expected to address this significant unmet clinical need.

Additionally, Entera is finalizing the development of an optimized formulation for EB612 which may enable twice a day administration (versus the previous 4 times a day) to patients with hypoparathyroidism. The Company anticipates conducting a first–in–human PK study of the new formulation in the first half of 2023. Entera previously conducted a pilot 4–month Phase 2 study, results of which were presented (ASBMR 2015) and published in a peer–reviewed journal (JBMR 2021), as well as a Phase 2 PK–PD study versus Natpara, whose findings have also been publicly presented (ASBMR 2019). These studies demonstrated that EB612 induced a rapid decline in median serum phosphate levels and maintenance of target calcium levels throughout the study, even as patients were able to meaningfully reduce their calcium and active vitamin D supplementation which is key to reducing common comorbidities of this disease.

Finally, Entera announced the formation of its Clinical and Scientific Advisory Board (CSAB), comprising world class experts in bone diseases, endocrinology, and metabolic disorders and will be presenting incremental data from its 6–month Oral PTH (EB613) Phase 2 Study in postmenopausal women with low bone mass, at the 2022 Annual Meeting of the American Society for Bone and Mineral Research (ASBMR), which will take place in Austin, Texas from September 9–12, 2022.

Financial Results for the Six–Month Period Ended June 30, 2022

Revenues for the six months ended June 30, 2022 were $112,000 compared to $226,000 for the six months ended June 30, 2021. In this period, the majority of our revenues were attributable to research and development, or R&D services provided to Amgen under our 2018 collaboration agreement. The cost of revenues for the six months ended June 30, 2022 were $87,000 compared to $172,000 for the six months ended June 30, 2021 and were primarily attributed to salaries and related expenses in connection with the R&D services provided to Amgen.

Operating expenses for the six months ended June 30, 2022 were $7.1 million compared to $5.0 million for the six months ended June 30, 2021. Entera's operating loss was $7.1 million for the six months ended June 30, 2022, compared to $4.9 million for the six months ended June 30, 2021.

Research and development expenses for the six months ended June 30, 2022 were $3.1 million, compared to $2.4 million for the six months ended June 30, 2021, an increase of $0.7 million. The increase was primarily due to an increase of $0.7 in materials and production costs and pre–clinical activity as part of the preparation for our Phase 3 clinical trial for EB613 and an increase of $0.4 million in employee's compensation. The increase was partially offset by a decrease of $0.4 million in other clinical trial expenses related to our Phase 2 trial for EB613 that was completed in June 2021.

General and administrative expenses for the six months ended June 30, 2022 were $4.1 million, compared to $2.7 million for the six months ended June 30, 2021, an increase of $1.4 million. The increase of $1.4 million was mainly attributable to an increase of $0.8 million in share–based compensation granted to non–executive directors and employees, an increase of $0.4 million in legal, accounting fees and others consultants and an increase of $0.2 million in D&O insurance costs.

The net comprehensive loss was $7.0 million or $0.24 per ordinary share (basic and diluted) for the six months ended June 30, 2022, compared to $4.9 million, or $0.21 per ordinary share (basic and diluted) for the six months ended June 31, 2021.

As of June 30, 2022, Entera had cash and cash equivalents of $17.3 million, compared to $20.1 million as of March 31, 2021.

Entera expects that the current cash is sufficient to fund the operations through the second quarter of 2023.

About EB613 (a.k.a. EBP05)

Parathyroid hormone (PTH) is an 84–amino acid hormone and the primary regulator of calcium and phosphate metabolism in bone and kidney. EB613 is an oral formulation of synthetic hPTH (1–34), (teriparatide), a peptide consisting of the first 34 amino acids of PTH which represent the functional region. Subcutaneous Forteo (teriparatide injection) has been the leading anabolic treatment of osteoporosis since 2002. EB613 utilizes Entera's oral drug delivery platform which promotes enteric absorption and stabilizes teriparatide in the gastrointestinal tract. Entera's Oral PTH formulations have been administered collectively to a total of 225 subjects in two Phase 1 studies and 3 phase 2 studies (including 35 in 2 phase 2 hypoparathyroidism studies). The most recent study was a dose ranging Phase 2 study in postmenopausal women with low bone mass. This study met primary and key secondary endpoints and was presented in a late–breaker oral presentation at the ASBMR 2021 conference. For the primary efficacy endpoint: a statistically significant increase in P1NP (a bone formation marker) at 3 months was achieved. A significant dose response was observed for 0.5, 1.0, 1.5 and 2.5 mg oral PTH doses on P1NP, Osteocalcin and bone mineral density (BMD). Subjects receiving the 2.5 mg dose of EB613 showed significant increases in dose–related BMD at the lumbar spine, total hip, and femoral neck at 6 months. Subjects receiving the 2.5 mg dose of EB613 daily for 6 months had a significant placebo adjusted increase of 3.78% in lumbar spine BMD (p<0.008) which is similar to the 3.9% increase in lumbar spine BMD seen with Forteo in clinical studies reported in the literature. Increases in total hip and femoral neck BMD were greater than those previously reported with Forteo . EB613 exhibited an excellent safety profile, with no drug related serious adverse events. The most common adverse events included mild nausea, moderate back pain, moderate headache, and moderate upper abdominal pain.
