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


WARRINGTON, Pa., May 13, 2021 /PRNewswire/ -- Windtree Therapeutics, Inc. (Formerly Known As Discovery Laboratories, Inc.), Inc. (NasdaqCM: WINT), a biotechnology and medical device company focused on advancing multiple late-stage interventions for acute cardiovascular and pulmonary disorders, today reported financial results for the first quarter ended March 31, 2021 and provided key business updates.

Key Business and Financial Updates

  • Expanded the participating countries and sites in the Company's Phase 2 global clinical study of istaroxime for the treatment of Early Cardiogenic Shock in severe acute heart failure patients. Cardiogenic shock is a severe form of heart failure marked by critically low blood pressure. This study builds upon observations from the acute heart failure program and will assess the ability of istaroxime to improve blood pressure in these patients and is expected to be completed in the second half of 2021.
  • Dosed the first patient in its Phase 2 clinical trial studying lucinactant, the Company's KL4 surfactant, in acute lung injury in adults with COVID-19 associated acute respiratory distress syndrome (ARDS). The study is designed to evaluate key safety and physiological measures and is expected to be completed in Q3 2021.
  • Completed an equity financing raising approximately $30.0 million in gross proceeds during the first quarter of 2021, before deducting underwriting discounts and commissions and other estimated offering expenses. Net proceeds from the offering were approximately $27.4 million.
  • Announced pursuit of additional expedited patent protection for our lead asset istaroxime with the filing of a Track One prioritized patent application with the U.S. Patent and Trademark Office for a patent stemming from an application previously filed under the Patent Cooperation Treaty. Under the Track One program, the new istaroxime patent is expected to receive review and final disposition within a year of priority status being granted, rather than the customary three-year examination for non-prioritized examinations.
  • Extended the scientific collaboration with the University of Milan-Bicocca for further characterization and development of the Company's oral SERCA2a compounds for the potential treatment of chronic and acute human heart failure.

"With additional countries and sites opening and dosing patients in our Phase 2 global clinical study of istaroxime for the treatment of Early Cardiogenic Shock in severe acute heart failure patients and the first patient dosed in our Phase 2 study of lucinactant in acute lung injury in adults with COVID-19 associated ARDS, our first quarter was off to a very productive start," said Craig Fraser, President and Chief Executive Officer of Windtree. "As we look to the rest of the year, we see several potential value-creating milestones with data readouts anticipated in both Phase 2 trials. Additionally, we are actively engaged on the business development front, and are encouraged by the level of interest. Importantly, with the successful completion of a financing this quarter, our balance sheet provides the runway to continue to help fuel these current and planned development activities. We are focused on execution and a year of important milestones."

Select Financial Results for the First Quarter ended March 31, 2021

For the first quarter ended March 31, 2021, the Company reported an operating loss of $9.1 million, compared to an operating loss of $6.7 million in the first quarter of 2020.

Research and development expenses were $4.4 million for the first quarter of 2021, compared to $3.5 million for the first quarter of 2020. The increase in research and development expenses is primarily due to costs related to the clinical development of istaroxime.

General and administrative expenses for the first quarter of 2021 were $4.7 million, compared to $3.2 million for the first quarter of 2020.

The Company reported a net loss of $9.0 million ($0.51 per basic share) on 17.7 million weighted-average common shares outstanding for the first quarter ended March 31, 2021, compared to a net loss of $6.5 million ($0.48 per basic share) on 13.7 million weighted average common shares outstanding for the comparable period in 2020.

As of March 31, 2021, the Company reported cash and cash equivalents of $38.5 million.
