Windtree Therapeutics Reports Third Quarter 2022 Financial Results and Provides Key Business Updates

WARRINGTON, Pa., Nov. 14, 2022 (GLOBE NEWSWIRE) — Windtree Therapeutics, Inc. (NasdaqCM: WINT), a biotechnology company focused on advancing multiple late-stage interventions for cardiovascular disorders, today reported financial results for the third quarter ended September 30, 2022 and provided key business updates.

“The Company had several notable deliverables this quarter and continues to focus on progressing its planned development of istaroxime. The positive results of the SEISMiC study of istaroxime in early cardiogenic shock have been well received in many scientific forums. At the same time, our team has been active in working to advance istaroxime into the next clinical trial in early cardiogenic shock. To support development and company operations, we are addressing our resources by exploring options for financing, as well as actively engaging in business development activities, both licensing and strategic,” said Craig Fraser, President and Chief Executive Officer of Windtree. “Additionally, the out-licensing of our acute pulmonary KL4 surfactant platform this quarter supports our portfolio and resource prioritization strategy as we focus on istaroxime and the significant opportunity in the major markets of cardiogenic shock and heart failure. With all that we are executing, we look forward to providing our shareholders with updates on our plans and progress.”

Key Business Updates

  • Announced a Global License Agreement with Lee’s Pharmaceutical (HK) Limited (Lee’s (HK)) and its affiliate Zhaoke Pharmaceutical (Hefei) Co. Ltd. (Zhaoke), for the development and commercialization of Windtree’s acute pulmonary pipeline treatments, KL4 surfactant and drug/device combination, AEROSURF®, for the treatment of preterm infants with respiratory distress syndrome and other potential applications. Under terms of the global license agreement, Lee’s (HK) and Zhaoke received a global license to develop and commercialize Surfaxin®, lyophilized lucinactant, and AEROSURF for any potential indications and applications. Lee’s (HK) and Zhaoke will be responsible for funding all development, intellectual property, manufacturing, and commercialization activities and provide developmental, regulatory, and eventual commercial sales milestones for Windtree of up to $78.9 million plus potential double-digit royalties. Windtree had previously granted a regional license to Lee’s (HK) and Zhaoke for KL4 and AEROSURF for the territory of Greater China, for which Windtree received an upfront payment, and this new agreement expands that territory globally. With the execution of this agreement, Windtree no longer has ongoing maintenance and operating costs for the KL4 surfactant platform.
  • Announced a Late Breaker presentation of the Company’s positive Phase 2 SEISMiC study at the Heart Failure Society of America Annual Scientific Meeting in Washington, D.C. The presentation described dose response data from the trial, where the primary endpoint was the improvement in systolic blood pressure over the first six hours of study drug infusion. Both doses improved the blood pressure profile through 24 hours.
  • Announced the publication of positive results of the Company’s Phase 2 istaroxime study in early cardiogenic shock in the European Journal of Heart Failure. The study entitled, “Safety and efficacy of istaroxime in patients with acute heart failure-related pre-cardiogenic shock – a multicentre, randomized, double-blind, placebo-controlled, parallel group study (SEISMiC)” showed significant improvement in blood pressure profiles that persisted through 24 hours.
  • Announced a Notice of Allowance from the U.S. Patent and Trademark office (USPTO) for a new istaroxime patent. A notice of allowance is issued by the USPTO to indicate that the application has passed its examination. The U.S. Patent, titled: “Istaroxime-containing Intravenous Formulation for the Treatment of Acute Heart Failure (AHF)” is a continuing patent application of the expedited U.S. Track One filing by Windtree. The claims cover longer infusion durations of istaroxime for improved outcomes in the treatment of acute heart failure. In particular, the claims are directed to an improvement in diastolic heart function following administration of istaroxime by intravenous infusion for six hours or more, which Windtree attributes to the SERCA2a mechanism of action of istaroxime and its metabolites.
  • Presented at two Wall Street investor conferences, including the Ladenburg Thalmann Healthcare Conference and H.C. Wainwright’s 24th Annual Global Investment Conference.
  • Held an Oppenheimer virtual fireside chat on istaroxime in heart failure and cardiogenic shock. The fireside chat featured perspectives from Alexandre Mebazaa, MD, PhD, of Hôpital Lariboisière, Paris, France on the immense need for pharmacologic innovation in cardiogenic shock.

Select Financial Results for the Third Quarter ended September 30, 2022

For the third quarter ended September 30, 2022, the Company reported an operating loss of $4.7 million, compared to an operating loss of $8.1 million in the third quarter of 2021. Included in operating loss for the third quarter of 2022 is non-cash expense of $0.5 million related to the impairment of goodwill

Research and development expenses were $1.5 million for the third quarter of 2022, compared to $4.7 million for the third quarter of 2021. The decrease in research and development expenses is primarily due to (i) a decrease of $1.9 million related to the KL4 surfactant platform as we continue to focus our resources on the development of our istaroxime pipeline; (ii) a decrease of $0.5 million in non-cash stock-based compensation expense; (iii) a decrease of $0.5 million for expenditures related to the development of istaroxime for AHF; and (iv) a decrease of $0.3 million following the completion of enrollment in the SEISMiC study in March 2022.

General and administrative expenses for the third quarter of 2022 were $2.7 million, compared to $3.5 million for the third quarter of 2021. The decrease in general and administrative expenses is primarily due to (i) a decrease of $0.4 million in professional fees; and (ii) a decrease of $0.4 million in non-cash stock-based compensation expense.

The Company reported a net loss of $4.1 million ($0.13 per basic share) on 31.1 million weighted-average common shares outstanding for the quarter ended September 30, 2022, compared to a net loss of $8.2 million ($0.31 per basic share) on 26.7 million weighted average common shares outstanding for the comparable period in 2021.

As of September 30, 2022, the Company reported cash and cash equivalents of $8.4 million, which is expected to be sufficient to fund operations into the second quarter of 2023.

Readers are referred to, and encouraged to read in its entirety, the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2022, which will be filed with the Securities and Exchange Commission on November 14, 2022, and includes detailed discussions about the Company’s business plans and operations, financial condition, and results of operations.
