Atossa Therapeutics Announces Second Quarter 2021 Financial Results - Provides Corporate Update and Information about Upcoming Stockholder Meeting

SEATTLE, Aug. 13, 2021 (GLOBE NEWSWIRE) -- Atossa Therapeutics, Inc. (NASDAQ:ATOS), a clinical-stage biopharmaceutical company seeking to discover and develop innovative medicines in oncology and infectious disease with a current focus on breast cancer and COVID-19, today announces financial results for the fiscal quarter ended June 30, 2021, and provides an update on recent company developments.

Key developments from Q2 2021 and to date include:

• Atossa received final data from its open-label Phase 2 clinical study of oral Endoxifen administered in the "window of opportunity" between diagnosis of breast cancer and surgery, which showed that the primary endpoint of the study was achieved: Ki-67, a common measure of tumor cell activity, was reduced from an average of 25.6% at screening to 6% on the day of surgery, a 65.1% reduction. Ki-67 was reduced below 25% for all patients, which is potentially clinically meaningful because studies by others have shown that a reduction below 25% improves long term survival.
  
  
  
  
• Received authorization from Swedish regulators to initiate a Phase 2 clinical study of Endoxifen to reduce mammographic breast density (MBD).
  
  
  
  
• Received authorization from Australian regulators to initiate a clinical study of AT-H201 which is being developed for the treatment of patients with COVID-19 and "long haul" respiratory illness.
  
  
  
  
• Announced final results from its Phase 1 double-blinded, randomized, placebo-controlled clinical study using Atossa's proprietary drug candidate AT-301 administered by nasal spray. AT-301 was considered safe and well tolerated in healthy male and female participants in this study at two different dose levels over 14 days. AT-301 is being developed for at home use for patients recently diagnosed with COVID-19.
  
  
  
  
• Completed treatment of oral Endoxifen in an ovarian cancer patient under the FDA's Expanded Access Pathway. The patient has recurring, metastatic, late-stage ovarian cancer and had not improved on other therapies. Although organoid testing conducted by a third party had previously shown a strong response to Endoxifen in combination with Apelisib, she has unfortunately continued to experience disease progression and is not expected to continue treatment with Endoxifen.
  
  
  
  
• Through the completion of capital raising transactions and the exercise of warrants, Atossa has grown its cash balances quarter over quarter for the past three quarters, ending the second quarter 2021 with $142.4 million in cash and cash equivalents.
  
  
  
  
• Scheduled a special stockholder meeting for September 7, 2021 for the purpose of approving an increase in authorized shares of common stock. If the proposal is approved by the stockholders, Atossa does not intend to issue any of the newly authorized shares of common stock for the purpose of raising capital in the nine months following approval of the proposal at a price less than $10 per share. The newly authorized shares of common stock are intended to be used at any time to complete and/or support acquisitions, collaborations, partnerships and licensing transactions.

"We continue to experience encouraging progress in our MBD and COVID-19 programs, with new regulatory approvals being granted in Sweden for a Phase 2 trial in MBD and authorization in Australia to commence a Phase 2 study of AT-H201 for respiratory illness associated with COVID-19," said Dr. Steven Quay, Atossa's President and Chief Executive Officer.

"In the meantime, we continue to enjoy a strong balance sheet, which we have significantly expanded over the last three quarters and will facilitate our development plans over the near term. As we actively explore the possibility for strategic expansion into other areas where we might see near-term milestones and results, we also urge all of our shareholders to exercise their right to vote at our special stockholder's meeting on September 7, 2021. We urge a vote in favor of the proposal to increase authorized shares, which will provide the Company with the flexibility to issue shares as part of these potential acquisitions, collaborations and partnerships, a common strategy successful biotech companies seeking to grow shareholder value employ in order to create a more attractive opportunity for all. We look forward to continuing to update our stockholders on these opportunities as they develop," concluded Dr. Quay.

Quarter Ended June 30, 2021, Financial Results

For the quarter ended June 30, 2021, Atossa has no source of sustainable revenue and no associated cost of revenue.

As of June 30, 2021, the Company had cash, cash equivalents and restricted cash of approximately $142.5 million.

Operating Expenses

Total operating expenses were approximately $7,004,000 and $10,534,000 for the three and six months ended June 30, 2021, respectively, consisting of research and development ("R&D") expenses of approximately $3,799,000 and $5,177,000 respectively, and general and administrative ("G&A") expenses of approximately $3,205,000 and $5,357,000, respectively. Total operating expenses were approximately $3,936,000 and $6,873,000, respectively for the three and six month ended June 30, 2020, and consisted of R&D expenses of approximately $1,653,000 and $2,592,000, respectively, and G&A expenses of approximately $2,283,000 and $4,281,000 respectively. Total operating expenses for the three and six months ended June 30, 2021, as compared to the same period in 2020 increased approximately $3,068,000 and $3,661,000 or 78% and 53%, respectively.

Research and Development Expenses

R&D expenses for the three months ended June 30, 2021, were approximately $3,799,000, an increase of approximately $2,146,000 or 130% from total R&D expenses for the three months ended June 30, 2020, of approximately $1,653,000. R&D expenses for the six months ended June 30, 2021, were approximately $5,177,000, an increase of approximately $2,585,000 or 100% from total R&D expenses for the six months ended June 30, 2020, of approximately $2,592,000. The increase in R&D expense is attributed primarily to an increase in clinical trial expense of approximately $1,309,000 and an increase in compensation of approximately $211,000 due to the addition of two employees, as compared to the same period in 2020. Also included in R&D expenses is an increase of $1,000,000 attributable to a one-time fee we paid in June 2021 to a U.S. leading research institution for the exclusive right to negotiate for the acquisition of the world-wide rights to two oncology R&D programs. We expect our R&D expenses to continue to increase into 2021 as we seek to commence a clinical study of AT-H201, complete studies of AT-301, launch a Phase 2 clinical trial of Endoxifen in women with high breast density, and continue the development of other indications and therapeutics.

General and Administrative Expenses

G&A expenses were $3,205,000 for the three months ended June 30, 2021, an increase of approximately $922,000, or 40% from the total G&A expenses for the three months ended June 30, 2020, of approximately $2,283,000. G&A expenses for the six months ended June 30, 2021, were approximately $5,357,000, an increase of approximately $1,076,000 or 25% from total R&D expenses for the six months ended June 30, 2020, of approximately $4,281,000. The increase in G&A expenses for the three and six months ended June 30, 2021, is attributed to an increase in insurance costs of approximately $387,000 due to the addition of the COVID-19 clinical trials, professional fees of approximately $703,000 due primarily to increased proxy costs and increased compensation of approximately $170,000, offset by a reduction in legal fees of approximately $301,000 compared to the same period in 2020. G&A expenses consist primarily of personnel and related benefit costs, facilities, professional services, insurance, and public company related expenses.
