    ソース: Nasdaq GlobeNewswire / 01 4 2024 16:00:00   America/New_York

    • Fully enrolled two Phase 2 studies with data from both expected in the second half of 2024
    • First patient dosed in new Phase 2 breast cancer prevention study
    • Data from ongoing Phase 2 EVANGELINE study scheduled to be presented at 2024 AACR Annual Meeting
    • Ended 2023 with $88.5 million of cash and cash equivalents and no debt

    SEATTLE, April 01, 2024 (GLOBE NEWSWIRE) -- Atossa Therapeutics, Inc. (Nasdaq: ATOS) (“Atossa” or the “Company”), today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided an update on recent Company developments. Atossa is a clinical stage biopharmaceutical company developing proprietary innovative medicines in areas of significant unmet medical need in oncology with a focus on breast cancer and other breast conditions.

    Key developments from Q4 2023 and the year to date include:

    • Full enrollment of Phase 2 Karisma-Endoxifen Clinical Trial – the study is investigating (Z)-endoxifen in premenopausal women with measurable breast density. Participants receive daily doses of (Z)-endoxifen for six months, over the course of which mammograms are conducted to measure reduction in breast density. Full enrollment was achieved in November 2023 and data is expected in the second half of 2024.

    • Full enrollment of Phase 2 I-SPY 2 Clinical Trial – (Z)-endoxifen is being evaluated as a neoadjuvant treatment in a study arm of the ongoing I-SPY 2 clinical trial. The study arm targets patients with newly diagnosed estrogen receptor-positive breast cancer whose tumors are predicted to be sensitive to endocrine therapy but for whom chemotherapy is expected to provide little or no benefit. Full enrollment was achieved in February 2024 and data is expected in the second half of 2024.

    • First patient dosed with (Z)-endoxifen in RECAST DCIS study – the Re-Evaluating Conditions for Active Surveillance Suitability as Treatment: Ductal Carcinoma In Situ (RECAST DCIS) study is an ongoing Phase 2 platform study designed to offer women diagnosed with DCIS six months of neoadjuvant endocrine therapy with the intent of determining their suitability for long-term active surveillance without surgery.

    • Expanded access patient concluded five-years of (Z)-endoxifen treatment – the pre-menopausal, Estrogen Receptor positive (ER+) / Human Epidermal Growth Factor Receptor 2 negative (HER2-), breast cancer patient who received neoadjuvant and adjuvant (Z)-endoxifen therapy under an FDA-approved "expanded access" program completed five years of successful treatment.

    • Data from ongoing EVANGELINE study scheduled to be presented at the AACR Annual Meeting – safety and efficacy data from the 40mg pharmacokinetic run-in cohort of the ongoing Phase 2 EVANGELINE (Endoxifen Versus exemestANe GosEreLIn) study is scheduled to be presented on April 9, 2024 at the American Association for Cancer Research (AACR) Annual Meeting. The data is scheduled to be presented by Dr. Matthew Goetz, deputy director of translational research for the Mayo Clinic Comprehensive Cancer Center and co-leader of the Mayo Clinic Women's Cancer Program. Dr. Goetz is also the primary investigator of the EVANGELINE study.

    • Appointment of Tessa Cigler, M.D., M.P.H and Jonathan Finn, CFA to Atossa’s Board of Directors – Dr. Cigler is a medical oncologist and clinical investigator at the Weill Cornell Breast Center in New York City. As a member of the Weill Cornell Breast Center research team, she heads several clinical trials designed to provide her patients with access to the new promising options for therapy and supportive care. Mr. Finn has more than 25 years of experience in the financial industry with a focus on early to mid-stage biotech and technology companies. He currently serves as Executive Vice President and Chief Investment Officer at Vantage Consulting Group, an investment advisory firm. 

    "I am very proud of the progress we made in Q4 2023 and the momentum we have continued to generate in 2024,” said Steven Quay, M.D., Ph.D., Atossa’s President and Chief Executive Officer. "With important data from our EVANGELINE study being presented at AACR this month and primary data from two of our Phase 2 studies expected in the second half of this year, the remainder of 2024 will be a critical period for our Company. Our focus continues to be on accelerating our (Z)-endoxifen development program and generating additional data to support the growing body of evidence that (Z)-endoxifen has the potential to address significant unmet needs that exist in both the breast cancer prevention and treatment settings.”

    Comparison of the Year Ended December 31, 2023 and 2022

    Operating Expenses.Total operating expenses were $31.4 million for the year ended December 31, 2023, which was an increase of $3.7 million, from the year ended December 31, 2022 of $27.7 million. Factors contributing to the increased operating expenses in the year ended December 31, 2023 are explained below.

    The following table provides a breakdown of major categories within R&D expense for the years ended December 31, 2023 and 2022, together with the dollar change in those categories (in thousands):

      Year Ended
    December 31,
    2023
     Year Ended
    December 31,
    2022
     Increase
    (decrease)
     
    Research and Development Expense       
     Clinical and non-clinical trials$12,722 $10,225 $2,497 
     Compensation$3,474  4,268  (794)
     Professional fees and other$1,138  590  548 
     Research and Development Expense Total$17,334 $15,083 $2,251 


    R&D Expenses.
    R&D expenses for the year ended December 31, 2023, were $17.3 million, an increase of $2.3 million from total R&D expenses for the year ended December 31, 2022 of $15.1 million. Key changes were as follows:

    • The increase in R&D expense was in part due to increased spending on clinical and non-clinical trials of $1.1 million compared to the prior year due to increased spending on (Z)-endoxifen trials, including drug development costs. The additional increase of $1.4 million was due to a change in estimate of the amount that no longer met the reasonably assured threshold to be sustained under a potential ATO audit related to R&D expenditures under the Australian R&D tax incentive program as a result of recent Australian Taxation Office guidance.

    • The decrease in R&D compensation expense for the year ended December 31, 2023 compared to the prior year was primarily due to a decrease in non-cash stock-based compensation of $0.8 million. Non-cash stock-based compensation decreased compared to the prior year due to the weighted average fair value of options amortizing in the year ended December 31, 2023 being lower year over year.

    • The increase in R&D professional fees and other was due in part to the refund in the prior year of $1.0 million from a research institution with which we had an exclusive right to negotiate for the acquisition of worldwide rights of two oncology programs. No exclusivity payments were made or refunded during the year ended December 31, 2023.

    The following table provides a breakdown of major categories within General and Administrative (G&A) expenses for the years ended December 31, 2023 and 2022, together with the dollar change in those categories (in thousands):

      Year Ended
    December 31,
    2023
     Year Ended
    December 31,
    2022
     Increase
    (decrease)
     
    General and Administrative Expense       
     Compensation$7,388 $7,429 $(41)
     Professional fees and other$5,367  3,539  1,828 
     Insurance$1,288  1,640  (352)
     General and Administrative Expense Total$14,043 $12,608 $1,435 


    G&A Expenses.
    G&A expenses for the year ended December 31, 2023 were $14.0 million an increase of $1.4 million from total G&A expenses for year ended December 31, 2022 of $12.6 million. Key changes were as follows:

    • The decrease in G&A compensation expense of $41 thousand for the year ended December 31, 2023 compared to the prior year was partially due to an increase in cash compensation expense of $1.3 million, offset by a decrease in non-cash stock-based compensation of $1.4 million. The increase in cash compensation expense compared to the prior year was primarily driven by salary and bonus severance costs for former executives of $0.6 million, an increase of $0.4 million due to compensation for new employees as well as an overall increase in salaries, bonuses and benefits of $0.3 million. Non-cash stock-based compensation decreased by $1.4 million due to the weighted average fair value of options amortizing in 2023 being lower year over year.
        
    • The increase in G&A professional fees of $1.8 million for the year ended December 31, 2023 compared to the prior year was primarily due to an increase in legal fees for higher patent-related activity of $0.7 million and an increase in professional fees of $0.8 million primarily due to higher investor relations costs and accounting fees. The additional increase of $0.4 million was due to a change in estimate related to the Australian R&D tax incentive program.

    • The decrease in G&A insurance expense of $0.4 million for the year ended December 31, 2023 compared to the prior year was due to lower negotiated insurance premiums for the same or better coverage year over year.

    Impairment Charge on Investment in Equity Securities. For the year ended December 31, 2023, we wrote down our investment in DCT by $3.0 million due to an impairment charge. For the year ended December 31, 2022 there were no impairment charges related to our equity securities.

    Interest Income. Interest income was $4.3 million for the year ended December 31, 2023, an increase of $3.5 million from interest income of $0.9 million for the year ended December 31, 2022. The increase was due to the higher average balance invested in money market funds of $26.5 million and higher average interest rates for the year ended December 31, 2023 compared to the prior year.

    About (Z)-Endoxifen
    (Z)-endoxifen is the most potent Selective Estrogen Receptor Modulator (SERM) for estrogen receptor inhibition and also causes estrogen receptor degradation. It has also been shown to have efficacy in the setting of patients with tumor resistance to other hormonal treatments. In addition to its potent anti-estrogen effects, (Z)-endoxifen has been shown to target PKCβ1, a known oncogenic protein, at clinically attainable blood concentrations. Finally, (Z)-endoxifen appears to deliver similar or even greater bone agonistic effects while resulting in little or no endometrial proliferative effects compared with standard treatments, like tamoxifen.

    Atossa is developing a proprietary oral formulation of (Z)-endoxifen that does not require liver metabolism to achieve therapeutic concentrations and is encapsulated to bypass the stomach, as acidic conditions in the stomach convert a significant proportion of (Z)-endoxifen to the inactive (E)-endoxifen. Atossa’s (Z)-endoxifen has been shown to be well tolerated in Phase 1 studies and in a small Phase 2 study of women with breast cancer. (Z)-endoxifen is currently being studied in four Phase 2 trials: one in healthy women with measurable breast density, one in women diagnosed with ductal carcinoma in situ, and two other studies including the EVANGELINE study in women with ER+/HER2- breast cancer. Atossa’s (Z)-endoxifen is protected by three issued U.S. patents and numerous pending patent applications.
