Atossa Therapeutics Announces First Quarter 2021 Financial Results and Provides Corporate Update

SEATTLE, May 14, 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 March 31, 2021, and provides an update on recent company developments.

Key developments from Q1 2021 and to date include:

• Atossa concluded its open-label Phase 2 clinical study of oral Endoxifen administered in the “window of opportunity” between diagnosis of breast cancer and surgery based on positive results allowing acceleration of the Endoxifen program in the United States
• Announced updated findings following 24 months of an Expanded Access (or “compassionate use”) single-patient study of Endoxifen for breast cancer. The patient in the study had no cancer recurrence and suffered no side effects. Endoxifen did not cause other safety and tolerability concerns in this patient
• Received a “Safe to Proceed” letter under the Expanded Access Pathway from the FDA permitting the use of Atossa’s oral Endoxifen as a treatment in an ovarian cancer patient and began treatment
• 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 to be 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 financing transactions with net proceeds of approximately $136 million beginning in December 2020 through the end of Q1

Atossa’s 2021 Annual Stockholder Meeting is scheduled for today, May 14, 2021 at 1 p.m. Pacific Time. As part of the meeting, Atossa management has decided to withdraw from consideration the proposal to increase authorized shares of common stock by 325 million.

“During the first quarter of 2021 we continued our two key development programs, namely our Phase 2 study of oral Endoxifen for the ‘window of opportunity’ between diagnosis of breast cancer and surgery and our Phase 1 study of AT-301 nasal spray for at-home use for patients recently diagnosed with COVID-19,” said Dr. Steven Quay, Atossa’s President and Chief Executive Officer. “In addition, we continued our ongoing expanded access program with Endoxifen in which the drug continues to be well tolerated and breast cancer recurrence has not been seen clinically. We also received an important authorization from the FDA for an additional expanded access treatment program in an ovarian cancer patient. Combined with very encouraging results in our COVID-19 program with AT-301 nasal spray, we continued to make great progress over the quarter.”

“In the meantime, we leveraged favorable conditions in the capital markets to strengthen our balance sheet over the last few months placing Atossa in a good position to execute on these and potential additional business opportunities during the remainder of 2021. As a result, we are diligently moving our existing programs forward, while actively exploring the possibility for strategic expansion into other areas where we might see near-term milestones and results. We look forward to continuing to update our stockholders on these opportunities as they develop,” concluded Dr. Quay.

Quarter Ended March 31, 2021 Financial Results 

For the quarter ended March 31, 2021, Atossa has no source of sustainable revenue and no associated cost of revenue.

As of March 31, 2021, the Company had cash, cash equivalents and restricted cash of approximately $137.7 million.

Operating Expenses Total operating expenses were $3,531,000 for the quarter ended March 31, 2021, compared to $2,937,000 during the same period of 2020, an increase of $594,000 or approximately 20%. Operating expenses for 2021 consisted of research and development ("R&D") expenses of $1,379,000 and general and administrative ("G&A") expenses of $2,152,000. Operating expenses for 2020 consisted of R&D expenses of $939,000, and G&A expenses of $1,998,000.

Research and Development ExpensesR&D expenses for the three months ended March 31, 2021, were $1,379,000, an increase of $440,000 or 47% from total R&D expenses for the same period in 2020 of $939,000. The increase in R&D expense is attributed primarily an increase in clinical trial expense of approximately $319,000 and an increase in salaries of approximately $118,000 due to the addition of employees, as compared to the same period in 2020. We expect our R&D expenses to continue to increase into 2021 as we seek to commence a 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 ExpensesG&A expenses were $2,152,000 for the three months ended March 31, 2021, an increase of $154,000, or 8% from the total G&A expenses for the three months ended March 31, 2020, of $1,998,000. The increase in G&A expenses for the three months ended March 31, 2021, is mainly attributed to an increase in insurance and professional fees of approximately $286,000 offset by a reduction in legal fees and compensation of approximately $152,000 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.
