Atossa Therapeutics Announces Second Quarter 2022 Financial Results and Provides Corporate Update

SEATTLE, Aug. 08, 2022 (GLOBE NEWSWIRE) — Atossa Therapeutics, Inc. (Nasdaq: ATOS), a clinical-stage biopharmaceutical company seeking to develop innovative proprietary 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, 2022, and provides an update on recent company developments.

Key developments from Q2 2022 and to date include:

  • Completed dosing in both Part B and Part C (of four parts) of Phase 1/2a Clinical Trial of AT-H201 in healthy volunteers, which the Company was developing as an inhalation therapy for moderately to severely ill hospitalized COVID-19 patients and for “long-haul” patients with post-infection pulmonary disease.
  • Announced plans to shift the development of AT-H201 to more closely align with its oncology focus by continuing the development in patients with compromised lung function due to the damaging effects of cancer treatment.
  • Entered into an agreement with a venture-capital backed, private company based in the United States that is in the pre-clinical stage of developing novel Chimeric Antigen Receptor (CAR) T-cell therapies based on technology licensed from a leading U.S. adult and pediatric cancer treatment and research institution. The agreement requires that up until November 1, 2022 the CAR-T company will negotiate exclusively with Atossa for Atossa to acquire the CAR-T company, and address certain matters related to personnel, operations and intellectual property.
  • Filed an investigational new drug application with the FDA to initiate a Phase 2 neoadjuvant clinical study of Atossa’s proprietary Endoxifen in premenopausal women with early-stage estrogen receptor positive and Human Epidermal Growth Factor Receptor 2 negative breast cancer in the United States. The FDA has issued a clinical hold letter requesting additional information which Atossa plans to submit by the end of the third quarter 2022 and to initiate enrollment in the fourth quarter 2022.

“We continue to make steady progress with our Endoxifen programs: one to reduce tumor cell activity in breast cancer patients in the neoadjuvant setting; and another to reduce dense breast tissue in women. Our work on AT-H201 demonstrated valuable outcomes, not the least of which was an understanding of how to pursue its development in the field of oncology. With the widespread availability of SARS-CoV-2 vaccines and other therapies now approved to treat COVID-19, we believe that altering the development pathways for AT-H201 in cancer patients with compromised lung-function resulting from radiation treatment may fill a compelling unmet medical need and create additional value for our stockholders. Lung injury caused by radiation treatment affects 30-40% of lung cancer patients, and ~35% of esophageal cancer patients. In non-small cell cancer patients receiving concurrent chemotherapy and radiation therapy the incidence of lung injury is estimated to be greater than 60%. As we previously announced, rather than proceeding with Part D of the AT-H201 study in COVID-19 patients, we plan to quickly initiate a clinical study of patients with compromised lung function caused by radiation treatment and we anticipate announcing next steps in the coming months,” commented Dr. Steven Quay, Atossa’s President and Chief Executive Officer.

Quarter Ended June 30, 2022 Financial Results (in thousands):

As of June 30, 2022, the Company had cash, cash equivalents and restricted cash of approximately $125,647.

For the quarter ended June 30, 2022, Atossa had no source of sustainable revenue and no associated cost of revenue.

Operating Expenses: Total operating expenses were $6,595 for the three months ended June 30, 2022, which is a decrease of $409 or 6%, from the three months ended June 30, 2021, of $7,004. Operating expenses for 2022 consisted of research and development (R&D) expenses of $3,433 and general and administrative (G&A) expenses of $3,162. Operating expenses for 2021 consisted of R&D expenses of $3,799, and G&A expenses of $3,205.

Research and Development Expenses: R&D expenses for the three months ended June 30, 2022, were $3,433, a decrease of $366 or 10% from total R&D expenses for the same period in 2021 of $3,799. Clinical and non-clinical trial costs as well as drug formulation and analysis for our clinical trials were consistent quarter over quarter. Total R&D compensation expense increased primarily due to an increase in stock-based compensation of $270 and increased salaries, bonus and benefits of $123. In addition, the Company paid a no-shop fee of $300 to negotiate the potential acquisition of a company focused on the pre-clinical stage of developing novel Chimeric Antigen Receptor (CAR) T-cell therapies based on technology licensed from a leading U.S. cancer treatment and research institution. Included in 2021 R&D expenses is an increase of $1,000 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.

General and Administrative Expenses: G&A expenses were $3,162 for the three months ended June 30, 2022, a decrease of $43, or 1% from the total G&A expenses for the three months ended June 30, 2021, of $3,205. G&A expenses for the three months ended June 30, 2022, increased $454 primarily due to an increase in non-cash stock-based compensation expense of $287 and an increase in other compensation of $167 due to the addition of a new employee quarter over quarter as well as salary, bonus and benefits increases. This increase was offset by a decrease of $533 in professional fees primarily due to a decrease in proxy costs in 2022.

Six Months Ended June 30, 2022 Financial Results (in thousands):

For the six months ended June 30, 2022, Atossa had no source of sustainable revenue and no associated cost of revenue.

Operating Expenses: Total operating expenses were $11,348 for the six months ended June 30, 2022, which is an increase of $814 or 8%, from the six months ended June 30, 2021 of $10,534. Operating expenses for 2022 consisted of R&D expenses of $4,937 and general and G&A expenses of $6,411. Operating expenses for 2021 consisted of R&D expenses of $5,177, and G&A expenses of $5,357.

Research and Development Expenses: R&D expenses for the six months ended June 30, 2022, were $4,937, a decrease of $240 or 5% from total R&D expenses for the same period in 2021 of $5,177. R&D expenses decreased because of a refund of $1,000 from the research institution that the Company had an exclusive right to negotiate for the acquisition of the world-wide rights to two oncology R&D programs. In February 2022, the other party did not honor its obligation to negotiate with us which lead to a cancellation of the agreement and refund of the $1,000 previously paid. Included in 2021 R&D expenses is an increase of $1,000 attributable the same one-time fee paid in June 2021. Additionally, on June 27, 2022, this decrease was offset by increased spending on clinical and non-clinical trials of $434 over the same period in 2021 due to additional drug manufacturing costs. Stock-based compensation, which is a non-cash charge, also increased $703 period over period, and other R&D compensation was up $202 due to salary, bonus and benefit increases. Professional expenses also increased $100 during the six months ended June 30, 2022 as compared to the same period in 2021. Finally, we paid $300 for the exclusive right to negotiate with a CAR-T Company for us to acquire the company.

General and Administrative Expenses: G&A expenses were $6,411 for the six months ended June 30, 2022, an increase of $1,054 or 20% from the total G&A expenses for the six months ended June 30, 2021, of $5,357. The increase in G&A expenses for the six months ended June 30, 2022, is primarily attributable to the increase in non-cash stock-based compensation expense of $1,020. Compensation expense also increased $431 due to the addition of a two new employees year over year as well as salary, bonus and benefit increases. Legal fees also increased $147 period over period due to increased patent activity. These increases are offset by the decrease in professional fees of $532 due primarily to the reduction of proxy costs period over period.

Dosing Completed in Part C of Atossa’s Phase 1/2a Study of AT-H201 in Healthy Volunteers
Atossa Plans to Initiate a New Development Path in Patients with Compromised Lung-Function Resulting from Cancer Treatment

SEATTLE, July 28, 2022 (GLOBE NEWSWIRE) — Atossa Therapeutics, Inc. (Nasdaq: ATOS) a clinical stage biopharmaceutical company seeking to develop innovative medicines in areas of significant unmet medical need in oncology and infectious diseases with a current focus on breast cancer and COVID-19, today announces it has completed dosing participants in Part C of its Phase 1/2a clinical study of its proprietary inhalation therapy (or, AT-H201) in Australia.

AT-H201 consists of two drugs previously approved by the FDA to treat other diseases. AT-H201 is intended to be inhaled via nebulizer with the goal of preventing or reducing lung injury that may be caused by fibrin deposition, fluid build-up and secondary infection.

Part C of the study involved administering the two drugs in succession in healthy volunteers. The study originally included a Part D which was designed to assess the effects of the treatment regimen in hospitalized COVID-19 patients with moderate illness. However, due to the rapidly shifting COVID-19 treatment landscape and the introduction of effective vaccines limiting hospitalizations, Atossa has evaluated indications for AT-H201 beyond COVID-19 patients, including treating and/or preventing lung injury in patients undergoing certain cancer treatments.

Rather than conducting Part D of the Phase 1/2a clinical study, Atossa now plans to shift the development of AT-H201 to closely align with its oncology focus by continuing the development in patients with compromised lung-function due to the damaging effects of cancer treatment. For example, radiation treatment can lead to radiation induced lung injury, which is poorly treated with current therapies and is often irreversible. Furthermore, radiation damage can limit the overall success of lung cancer treatment leading to a reduction in efficacy and poor disease control. AT-H201 has pharmacological properties to potentially curtail excessive radiation-induced lung injury without compromising standard of care cancer therapy for cancer patients. AT-H201 is designed to prevent and reduce dose-limiting toxicities, and enable a more durable therapeutic tumor response for cancer patients receiving pulmonary radiation.

“We are happy to have completed Parts A, B and C of the clinical trial and look forward to evaluating the results,” said Steven Quay, M.D., Ph.D., CEO and President of Atossa. “With widespread availability of SARS-CoV-2 vaccines and other therapies now approved to treat COVID-19, we believe that altering the development pathways for AT-H201 in patients with compromised lung-function resulting from radiation may fill a compelling unmet medical need and create more value for our stockholders.” Based on our work to date with AT-H201, we believe we can quickly initiate a clinical study in this setting and we plan to announce our next steps in the fourth quarter,” concluded Dr. Quay.

Radiation Induced Lung Injury (RILI)

RILI is damage to the lungs caused by ionizing radiation administered to treat cancer. RILI is a significant issue for patients undergoing radiation treatment for various forms of cancer and is often irreversible. For instance, RILI affects 30-40% of lung cancer patients, and ~35% of esophageal cancer patients. In non-small cell cancer patients receiving concurrent chemotherapy and radiation therapy the incidence of RILI is estimated to be greater than 60%. Although Atossa has not finalized the protocol for this new trial we believe RILI affects a significant number of patients across multiple cancer types and there is a meaningful need for new treatments.

About AT-H201

AT-H201 is a proprietary sequential dosing regimen of two previously approved by the FDA to treat other diseases, and by other administration routes. AT-H201 is intended to be inhaled via nebulizer to improve compromised lung function.

The Phase 1/2a study in Australia and other clinical studies must be successfully completed and regulatory approvals must be obtained before AT-H201 can be commercialized. No assurance can be given that the studies will be successful or that regulatory approvals will be obtained.

Atossa Therapeutics Announces First Quarter 2022 Financial Results and Provides Corporate Update

SEATTLE, May 09, 2022 (GLOBE NEWSWIRE) — Atossa Therapeutics, Inc. (Nasdaq: ATOS), a clinical-stage biopharmaceutical company seeking to develop innovative proprietary 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, 2022, and provides an update on recent company developments.

Key developments from Q1 2022 and to date include:

  • Received issuance of key U.S. patent covering Endoxifen directed to compositions of storage-stable Endoxifen and methods of treating hormone-dependent breast disorders using the storage-stable Endoxifen.
  • Announced planned U.S. Phase 2 clinical study of Endoxifen in the neoadjuvant setting (prior to surgery) to compare Endoxifen to standard of care in premenopausal women with breast cancer. A CRO has been engaged to work on this study and the Company also intends to retain a leading U.S. research institution to help manage the study. The Company anticipates submitting an IND to the FDA in the second quarter of 2022.
  • Completed Part B (second of four parts) of Phase 1b/2a clinical study of AT-H201 in Australia

“We continue to make steady progress with our Endoxifen programs: one to reduce tumor cell activity in breast cancer patients in the neoadjuvant setting; and another to reduce dense breast tissue in women,” commented Dr. Steven Quay, Atossa’s President and Chief Executive Officer. “Our Phase 2 study in women with measurable breast density continues to enroll participants in Stockholm and we have been preparing to submit a request (IND) to the FDA this quarter to open a Phase 2 study in the neoadjuvant setting here in the Unites States. We began 2022 with significant progress in our COVID-19 program, both initiating and completing key parts of our Phase1b/2a trial in Australia for AT-H201, and we have now completed the first two parts of that study.”

Quarter Ended March 31, 2022 Financial Results (in thousands):

For the quarter ended March 31, 2022, Atossa has no source of sustainable revenue and no associated cost of revenue.

As of March 31, 2022, the Company had cash, cash equivalents and restricted cash of approximately $131,596.

Operating Expenses:
Total operating expenses were $4,747 for the three months ended March 31, 2022, which is an increase of $1,216 or 34%, from the three months ended March 31, 2021. Operating expenses for 2022 consisted of research and development (R&D) expenses of $1,499 and general and administrative (G&A) expenses of $3,248. Operating expenses for 2021 consisted of R&D expenses of $1,379, and G&A expenses of $2,152.

Research and Development Expenses:
R&D expenses for the three months ended March 31, 2022, were $1,499, an increase of $120 or 9% from total R&D expenses for the same period in 2021 of $1,379. The increase in R&D expense is attributed to increased spending on clinical and non-clinical trials of $584 over 2021 due to additional drug manufacturing costs. Stock-based compensation, which is a non-cash charge, also increased $433 quarter over quarter, and other R&D compensation was up $79 due to salary bonus and benefit increases quarter over quarter. The increase in R&D was offset by a refund of $1,000 from the research institution that the Company had an exclusive right to negotiate for the acquisition of the world-wide rights to two oncology R&D programs. In February 2022, the other party did not honor its obligation to negotiate with us which lead to a cancellation of the agreement and refund of the $1,000 we paid them.

General and Administrative Expenses:
G&A expenses were $3,248 for the three months ended March 31, 2022, an increase of $1,096, or 51% from the total G&A expenses for the three months ended March 31, 2021, of $2,152. The increase in G&A expenses for the three months ended March 31, 2022, is primarily attributable to non-cash stock-based compensation expense of $734. Other compensation also increased $264 due to the addition of a new employee quarter over quarter as well as salary, bonus and benefit increases. Legal fees also increased $124 quarter over quarter due to increased patent activity.

Atossa Therapeutics Announces Completion of Part B of Clinical Study of AT-H201

NEBULIZED FORMULATION BEING DEVELOPED TO IMPROVE LUNG FUNCTION IN BOTH ACTIVE-DISEASE COVID-19 PATIENTS AND “LONG HAUL” PATIENTS WITH POST-INFECTION PULMONARY DISEASE

SEATTLE, April 20, 2022 (GLOBE NEWSWIRE) — Atossa Therapeutics, Inc. (Nasdaq: ATOS), a clinical stage biopharmaceutical company seeking to develop innovative medicines in areas of significant unmet medical need in oncology and infectious diseases with a current focus on breast cancer and COVID-19, today announces it has completed enrolling participants in Part B of its Phase 1/2a clinical study of AT-H201 in Australia, consisting of multiple ascending dose cohorts in healthy participants. AT-H201 is being developed as an inhalation therapy for moderately to severely ill hospitalized COVID-19 patients and for “long-haul” patients with post-infection pulmonary disease.

“Part B of the study was successfully completed and, subject to approval from the ethics committee, we will now proceed to enroll the next group of participants,” said Steven Quay, M.D., Ph.D., Atossa’s CEO and President. “Despite widespread availability of vaccines, many areas of the world are seeing a recent surge in COVID-19 cases. There continues to be a strong need for additional therapies to combat COVID-19.”

The Phase 1/2a placebo-controlled study will enroll a total of 60 healthy participants and moderately-ill hospitalized COVID-19 patients. The study has four parts: Part A – a single ascending dose part; Part B – a multiple ascending dose part; Part C – a combination part in healthy individuals; and Part D – a combination in COVID-19 infected patients. Parts A, B and C of the study are being conducted by Avance Clinical Pty Ltd., a leading Australian clinical research organization. Commencing Parts C and D of the study is subject to additional approvals from the Australian Human Research Ethics Committee.

AT-H201 is a proprietary combination of two drugs previously approved by the FDA to treat other diseases and by other administration routes. AT-H201 is intended to be inhaled via nebulizer to improve compromised lung function for moderately to severely ill, hospitalized COVID-19 patients, and for “long-haul” patients with post-infection pulmonary disease. In May 2020, we completed in vitro testing of AT-H201, which showed that the components of AT-H201 inhibit SARS-CoV-2 infectivity of VERO cells, a standard cell type being used to study infectivity of the coronavirus.

The Phase 1/2a study in Australia and other clinical studies must be successfully completed and regulatory approvals must be obtained before AT-H201 may be commercialized. No assurance can be given that studies will be successful or that regulatory approvals will be obtained.
