Windtree Therapeutics Reports Second Quarter 2019 Financial Results and Provides Key Business Updates

WARRINGTON, Pa., Aug. 14, 2019 /PRNewswire/ -- Windtree Therapeutics, Inc. (OTCQB: WINT), a biotechnology and medical device company focused on developing drug product candidates and medical device technologies to address acute cardiovascular and pulmonary diseases, today reported financial results for the second quarter ended June 30, 2019 and provided key business updates. 

Key Business and Financial Updates

During the second quarter of 2019, the Company continued to advance development activities to potentially transition its lead programs – istaroxime for acute heart failure and AEROSURF® for respiratory distress syndrome (RDS) in premature infants – towards phase 3 clinical trials; in addition, the Company continued to progress product development activities for rostafuroxin.


  • In May 2019, the Company presented new safety and efficacy data from a phase 2b study of istaroxime in patients hospitalized with acute heart failure (AHF) at a late-breaker session of the European Society of Cardiology (ESC) 2019 Heart Failure Congress. The study achieved its primary endpoint by demonstrating a significant improvement (p<0.05) in cardiac function at both istaroxime study doses and the Company observed a well characterized safety profile for istaroxime.
  • In June 2019, the Company engaged with the U.S. FDA and gained alignment on the direction of the istaroxime clinical development plan and continues to work with its advisors in preparing for the next clinical trial.
  • In August 2019, the Company announced that the U.S. FDA has granted Fast Track Designation for istaroxime for the treatment of acute heart failure.


  • In May 2019, the Company announced the results of a post-hoc, pooled analysis of previously released phase 2 data suggesting that AEROSURF may reduce the overall incidence and severity of bronchopulmonary dysplasia (BPD) in premature infants with RDS, regardless of whether the infant was ultimately intubated. These data were recently presented at the Pediatric Academic Societies (PAS) Meeting, the leading event for academic pediatrics and child health research.

Other Pipeline

  • The Company continued to advance its preclinical follow-on oral and intravenous SERCA 2a heart failure compounds.
  • In June 2019, the Company and Eleison Pharmaceuticals LLC announced positive results of a feasibility study using the Company's Aerosol Delivery System (ADS) aerosolization technology to deliver Eleison's inhaled lipid cisplatin (ILC). The results demonstrate the feasibility to aerosolize ILC for potential use in thoracic oncology treatment.


  • As of June 30, 2019, the Company had cash and cash equivalents of $6.1 million and $2.5 million of available-for-sale marketable securities.
  • The Company believes that it has sufficient cash, cash equivalents and available-for-sale marketable securities to fund its development activities, business operations and debt service through October 2019.

"Through the second quarter of 2019, we continued to make meaningful advancements in our lead programs – istaroxime and AEROSURF," commented Craig Fraser, President and Chief Executive Officer. "With the CVie acquisition, we met our goal to create a company with numerous, short- to mid-term value-creating opportunities in important disease areas. I am pleased with the continued strong progress made to advance istaroxime and AEROSURF, as we focus on executing our programs in a thoughtful and rigorous manner. We believe we have favorably positioned the Company with multiple clinical development and business milestones that could potentially be catalysts for value creation. We look forward to keeping our stakeholders updated on our plans, clinical execution and milestone achievements."

Select Financial Results for the Second Quarter ended June 30, 2019

For the quarter ended June 30, 2019, the Company reported an operating loss of $6.5 million compared to $3.0 million for the second quarter of 2018. The increase was primarily due to increases of $2.0 million in general and administrative expenses and $0.5 million in research and development expenses.

Research and development expenses were $3.4 million for the second quarter of 2019 compared to $2.9 million for the second quarter of 2018.

General and administrative expenses for the second quarter of 2019 were $3.2 million compared to $1.2 million for the second quarter of 2018. The increase was primarily due to a $1.1 million increase in non-cash stock compensation expense as a result of employee stock option grants in the fourth quarter of 2018 and during 2019. There were no employee stock option grants in the first half of 2018.  Also, there were increases of $0.5 million related to professional fees and $0.3 million related to employee incentive bonuses.

For the quarter ended June 30, 2019, the Company reported a net loss of $6.4 million ($0.20 per share) compared to a net loss of $3.1 million ($0.81 per share) for the second quarter of 2018.

As of June 30, 2019, the Company had cash and cash equivalents of $6.1 million and available-for-sale marketable securities of $2.5 million. In addition, as of June 30, 2019, the Company had current liabilities of $15.5 million (including $8.0 million in debt). The Company anticipates that its cash, cash equivalents and marketable securities are sufficient to fund its planned development activities, business operations and debt service through October 2019.  The Company plans, and is currently actively engaged in discussions with various parties, to secure additional capital, potentially through a combination of public or private equity offerings and strategic transactions, including potential alliances and drug product collaborations focused on specified geographic markets; however, none of these alternatives are committed at this time.

Readers are referred to, and encouraged to read in its entirety, the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2019 which is expected to be filed with the Securities and Exchange Commission on or before August 14, 2019 and includes a discussion of the Company's business plans and operations, financial condition and results of operations.
