TSX runs higher on rate cut expectations
WARRINGTON, Pa. – Windtree Therapeutics, Inc. (NASDAQ:WINT), a biotech company specializing in therapies for critical conditions, announced today positive topline results from its Phase 2b SEISMiC Extension Study of istaroxime in heart failure patients. The study showed that istaroxime significantly improved systolic blood pressure, cardiac output, and renal function without increasing heart rate or causing significant arrhythmias.
The study, which included patients in early cardiogenic shock—a condition characterized by low blood pressure due to heart failure—tested istaroxime against a placebo. The drug is designed to enhance both systolic contraction and diastolic relaxation of the heart while maintaining renal function. The SEISMiC Part B Extension Study randomized 30 subjects across the United States, Europe, and Latin America.
Istaroxime's primary endpoint was to improve systolic blood pressure over six hours, which was achieved with statistical significance in the combined Part A and Part B analysis compared to placebo. The study also noted improvements in cardiac output by approximately 15%, reductions in heart rate, and significant reductions in pulmonary capillary wedge pressure, which is associated with worsening heart failure and pulmonary edema.
Additionally, mixed venous oxygen saturation, an indicator of organ perfusion, was significantly improved, suggesting better tissue oxygen delivery. Renal function, measured by estimated glomerular filtration rate, also showed improvement. The New York Heart Association (NYHA) classification, which assesses heart failure severity, decreased significantly in the istaroxime group up to 72 hours, with a similar rate to placebo at 96 hours.
Serious adverse events were less frequent in the istaroxime group compared to placebo, with a safety profile generally consistent with previous clinical trials. Treatment-emergent adverse events were more common in the istaroxime group, mainly due to symptoms like nausea, vomiting, and headache.
The company's CEO, Craig Fraser, expressed satisfaction with the study results and the drug's unique profile. He indicated that the company is looking forward to advancing to the next development stages.

In other recent news, Windtree Therapeutics reported positive results from its Phase 2b SEISMiC Extension Study of istaroxime, a heart failure drug. The study achieved its primary endpoint, showing significant improvement in systolic blood pressure in patients with early cardiogenic shock due to heart failure. Furthermore, Windtree Therapeutics has undergone significant changes in its board and financial structure. The company appointed new independent directors, Saundra Pelletier and Jed Latkin, following the resignations of Daniel Geffken and Leslie Williams.

The company also issued a convertible promissory note for $350,000, maturing in 2025. These financial agreements led to a significant change in the company's share structure, with a 1-for-18 reverse stock split reducing the number of outstanding common shares from approximately 9.2 million to about 0.5 million.
In light of these developments, H.C. Wainwright maintained a Neutral rating on Windtree Therapeutics. All these recent developments are part of Windtree Therapeutics' ongoing efforts to secure additional capital and advance its clinical development programs.
InvestingPro Insights
While Windtree Therapeutics (NASDAQ:WINT) has reported positive topline results for its istaroxime study, the company's financial health presents a complex picture. According to InvestingPro data, WINT's market capitalization stands at a modest $1.52 million, reflecting its current position as a small-cap biotech firm.
InvestingPro Tips highlight some challenges facing the company. One tip indicates that WINT is "quickly burning through cash," which is not uncommon for biotech companies in the research and development phase but could be a concern for investors. Another tip suggests that the company "may have trouble making interest payments on debt," potentially impacting its ability to fund future clinical trials.
The stock's recent performance has been notably weak, with InvestingPro data showing a 1-week price total return of -25.07% and a 1-year price total return of -84.95%. This aligns with the InvestingPro Tip that the stock is "trading near 52-week low."
Despite these challenges, analysts have set a fair value target of $7 USD for WINT, significantly higher than its previous closing price of $2.57 USD. This suggests potential upside if the company can successfully commercialize its promising istaroxime treatment.
