“We were very pleased with the 3-month efficacy data for EB613 in the treatment of osteoporosis and look forward to announcing final 6 month BMD data this quarter. Despite the challenges of COVID, I am grateful to the patients, investigators and team’s focus to successfully executing the study. A safe and effective oral PTH alternative is expected to substantially increase patient compliance and participation, thereby expanding the treatment market and offering a higher quality of life for people living with osteoporosis,” stated Entera CEO Spiros Jamas. “Having identified new indications in which our formulations are showing preclinical efficacy, we are expanding the value of our platform and assets.”

Financial Results for the Quarter Ended March 31, 2021

Revenues for the quarter ended March 31, 2021 were $157,000 compared to $42,000 for the quarter ended March 31, 2020, with revenues in both years attributable to R&D services provided to Amgen. The cost of revenues for quarter ended March 31, 2021 and 2020 were $58,000 and $42,000 respectively and were comprised of salaries and related expenses in connection with the R&D services provided to Amgen.

Operating expenses were $2.5 million for the quarter ended March 31, 2021, compared to $2.9 million for the quarter ended March 31, 2020. Entera’s operating loss was $2.4 million for the quarter ended March 31, 2021, compared to $2.9 million for the quarter ended March 31, 2020.

Research and development expenses were $1.2 million for the quarter ended March 31, 2021, compared to $1.6 million for the quarter ended March 31, 2020. The decreasewas primarily due to a decrease of $0.2 million in professional and consulting services expenses due to submission of the IND in 2020 and a decrease of $0.2 million in EB613 clinical trial related expenses, including materials and production costs.

General and administrative expenses were $1.3 million for the quarter ended March 31, 2021, compared to $1.3 million for the quarter ended March 31, 2020. The quarter ended March 31, 2021 saw a decrease of $0.2 million in professional fees which was offset by an increase of $0.1 million in legal fees and $0.1 million in insurance and investor relations expenses.

Net comprehensive loss was $9.5 million or $0.43 per ordinary share (basic and diluted) for the quarter ended March 31, 2021 compared to $2.9 million, or $0.16 per ordinary share (basic and diluted) for the quarter ended March 31, 2020. The change in net loss was primarily due to the increase in the fair value of the warrants classified as financial liability, due to an increase in our market share price.

As of March 31, 2021, Entera had cash and cash equivalents of $16.4 million, compared to $8.6 million as of December 31, 2020. The increase was primarily due to sales under our ATM facility with Canaccord Genuity LLC.

Entera expects an operating loss of approximately $13.0 million for the year ending December 31, 2021 and believes its current cash position will be sufficient to fund its operations into the second quarter of 2022.

The Company’s Board of Directors has decided to accelerate the termination date of its outstanding warrants, upon satisfaction of the sale price condition and in accordance with the terms of the warrants.

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.
