WARRINGTON, Pa., Nov. 27, 2024 (GLOBE NEWSWIRE) -- Windtree Therapeutics, Inc. (“Windtree” or “the Company”) (NasdaqCM: WINT), a biotechnology company focused on advancing early and late-stage innovative therapies for critical conditions, today reported financial results for the third quarter ended September 30, 2024 and provided key business updates.

“The third quarter of 2024 was marked with significant progress. We were very pleased with the SEISMiC B study results in early cardiogenic shock showing significant improvement in many measures of cardiac function and blood pressure along with a favorable safety profile in patients with heart failure and cardiogenic shock. There have been four positive Phase 2 studies with over 300 patients treated with istaroxime resulting in a consistent, unique and attractive drug profile across a wide range of severities,” said Craig Fraser, Chairman and CEO. “With trial execution and active operations comes the need for capital and we successfully completed transactions providing resources for our near-term needs as well as secured an equity line of credit to potentially support future requirements,” Mr. Fraser added. “Looking forward, we plan to accelerate enrollments in the istaroxime SCAI Stage C cardiogenic shock study with a planned interim data read out in early Q2 2025 as well as providing guidance on our strategy and planned activities with our oncology preclinical aPKCi inhibitor assets. Given what we believe to be strong data and market need, the Company is turning attention to business development activities to secure additional licenses and partnerships for our multi-asset cardiovascular platform with the objective to secure non-dilutive capital and partner resources to advance the assets to potential commercialization.”

Key Business Updates

  • Announced positive Phase 2b topline clinical results with istaroxime significantly improving cardiac function and blood pressure in heart failure patients with early cardiogenic shock. The study met its primary endpoint in significantly improving systolic blood pressure over six hours (SBP AUC) for the combined Part A and Part B SEISMiC istaroxime group compared to placebo as well as for SEISMiC Part B alone. The improvements in SBP AUC at 24 hours were also significantly increased by istaroxime and the improvements were sustained through 96 hours of measurement. Cardiac output (the amount of blood pumped by the heart over a minute) and filling pressures in the heart significantly improved as did measured kidney function. Heart failure severity as assessed by the NYHA classification decreased significantly up to 72 hours compared to placebo. A favorable safety and tolerability profile, including risk for cardiac arrythmias, was also observed. The clinical study data was presented in a late-breaker session at the Heart Failure Society of America conference and the Company reviewed the clinical results along with the program strategy and plans at a virtual Investor Meeting which has been posted to the Company website.

  • Completed two private placements in July 2024 for aggregate proceeds of approximately $13.9 million, which consisted of approximately $4.4 million of new funding (with $2.3 million of net proceeds) and a $9.5 million payment through the full cancellation and extinguishment of certain holders outstanding senior notes, including secured notes, and shares of the Company’s Series B Convertible Preferred Stock.

  • Entered into a Common Stock Purchase Agreement with an equity line investor, whereby the Company has the right, but not the obligation, to sell such investor, and, subject to limited exceptions, the investor is obligated to purchase for up to $35 million of newly issued shares of the Company’s common stock.

  • Announced initiation of the SEISMiC C study of istaroxime in SCAI Stage C cardiogenic shock to complete Phase 2b and advance the transition to Phase 3. This is a global trial including sites in the U.S., Europe and Latin America. It is a placebo-controlled, double-blinded study with istaroxime being added to current standard of care with inotropes and/or vasopressors. The effect of istaroxime in addition to these therapies will be assessed for 6 hours and based on the patient’s condition, the ability to remove standard of care therapies while on istaroxime will also be assessed. The primary endpoint of the study is assessment of systolic blood pressure (SBP) profile over the first 6 hours of treatment.

  • Expanded patent estate with new patents with istaroxime in cardiogenic shock and acute heart failure. Cardiogenic shock national phase filings were completed for patent applications around the world, including in the United States, Germany, France, Italy, Japan and China. A patent was issued for istaroxime for Japan entitled, “Istaroxime-containing intravenous formulation for the treatment of heart failure and it has been accorded Patent No. 7560134. A patent was issued for istaroxime for Hong Kong, and it is entitled, “Istaroxime-containing intravenous formulation for the treatment of heart failure (AHF).” The claims are directed formulations comprising istaroxime, pharmaceutically acceptable salts thereof, and methods of use, alone, or in combination with other agents useful for the treatment and management of acute heart failure.
