Windtree Therapeutics Reports Third Quarter 2021
Financial Results and Provides Key Business Updates


WARRINGTON, PA November 10, 2021 Windtree Therapeutics, Inc. (NasdaqCM: WINT), a biotechnology company focused on advancing multiple late-stage interventions for acute cardiovascular and pulmonary disorders, today reported financial results for the third quarter ended September 30, 2021 and provided key business updates.


“I am very pleased to report on another productive quarter for Windtree. We continue to make progress with istaroxime, our lead clinical product candidate, and are focused on completing our phase 2 global study for the treatment of early cardiogenic shock, where we plan to announce topline data in Q1 2022. The need for new critical care cardiovascular therapies was clearly articulated during our KOL event held in October as well as in market research, and we believe istaroxime has the potential to be a meaningful new therapeutic innovation. The team is also busy preparing for the next study in our foundational program, acute heart failure with istaroxime. Concurrently, we are advancing an open-label phase 2 study of lucinactant (KL4) in patients with COVID-19 associated acute respiratory distress syndrome (ARDS) and anticipate topline data from this study in Q1 2022,” said Craig Fraser, President and Chief Executive Officer of Windtree. “Our business development group continues to be very active as we explore opportunities and engage with potential partners. Our balance sheet provides sufficient support of our upcoming clinical and regulatory milestones as well as company operations through 2022.”


Key Business and Financial Updates


Hosted Key Opinion Leader (KOL) webinar on istaroxime for the treatment of acute heart failure and the upcoming data in early cardiogenic shock, featuring a presentation by John Teerlink, M.D., University of California, San Francisco. Dr. Teerlink presented the current treatment landscape, highlighted the unmet medical need in treating patients with acute heart failure, and discussed the potential role for istaroxime based on clinical data he presented. Management followed with a presentation covering the clinical development program for istaroxime in early cardiogenic shock, which is currently in a phase 2 global study with data expected in the first quarter of 2022.



Continued executing the Company’s lead program for istaroxime in the treatment of patients in early cardiogenic shock due to heart failure. These patients are characterized by very low blood pressure and risk for hypo-perfusion to critical organs. The ongoing phase 2 global study is designed to build upon data which showed istaroxime improved cardiac function and dose-related increases in systolic blood pressure in acute heart failure patients.



Shared results from a U.S. physician survey and market research estimating that the worldwide total market value of cardiogenic shock is $1.25 billion. In the survey results, 99 out of 100 U.S.-based cardiologists responded that there was high need for pharmacologic (drug) treatment for early cardiogenic shock patients. Additionally, 84% of the cardiologists responded that for early cardiogenic shock patients they would be “likely to extremely likely” to use a drug with the observed characteristics of istaroxime.



Announced that the United States Patent and Trademark Office (USPTO) issued a Notice of Allowance of new patent claims for istaroxime administration. A notice of allowance is issued by the USPTO to indicate that the application has passed examination. When the new patent is issued by the USPTO, it will provide new intellectual property protection for istaroxime until late 2039.



Presented a corporate overview at the Oppenheimer Fall Healthcare Life Sciences and MedTech Summit.


Select Financial Results for the Third Quarter ended September 30, 2021


For the third quarter ended September 30, 2021, the Company reported an operating loss of $8.1 million, compared to an operating loss of $8.7 million in the third quarter of 2020.


Research and development expenses were $4.7 million for the third quarter of 2021, compared to $3.9 million for the third quarter of 2020.  The increase in research and development expenses is primarily due to an increase of $0.6 million for the clinical activity and development of istaroxime in early cardiogenic shock and acute heart failure.


General and administrative expenses for the third quarter of 2021 were $3.5 million, compared to $4.8 million for the third quarter of 2020. The decrease in general and administrative expenses is primarily due to a decrease of $0.8 million in severance costs and a decrease of $0.6 million in professional fees.


The Company reported a net loss of $8.2 million ($0.31 per basic share) on 26.7 million weighted-average common shares outstanding for the quarter ended September 30, 2021, compared to a net loss of $9.0 million ($0.54 per basic share) on 16.6 million weighted average common shares outstanding for the comparable period in 2020.


As of September 30, 2021, the Company reported cash and cash equivalents of $24.5 million. During October 2021, the Company raised an additional $3.2 million through its At-The-Market (ATM) program. The Company’s cash and cash equivalents as of September 30, 2021 and the additional funding from the ATM program are expected to be sufficient to fund operations through at least the next twelve months. 


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, 2021, which will be filed with the Securities and Exchange Commission on November 10, 2021, which includes detailed discussions about the Company’s business plans and operations, financial condition and results of operations.
