Windtree reports positive Phase 2b study on heart failure therapy

WARRINGTON, Pa. - Windtree Therapeutics, Inc. (NASDAQ:WINT), a biotechnology firm specializing in the development of therapies for critical diseases and currently valued at $1.44 million market capitalization, has announced positive results from its Phase 2b SEISMiC study of istaroxime. According to InvestingPro data, the company has seen a significant 28% return over the past week, though investors should note its overall Financial Health Score stands at 1.81, rated as ’FAIR’. The study findings were presented on Monday at the Technology and Heart Failure Therapeutics Conference in Boston, MA by Dr. Matteo Pagnesi, a cardiologist from Italy.

The SEISMiC study focused on the effects of istaroxime in patients experiencing early (SCAI Stage B) cardiogenic shock, a condition marked by dangerously low blood pressure and the risk of insufficient blood flow to vital organs. Istaroxime is a novel investigational therapy designed to improve cardiac function and elevate blood pressure, with the aim of reversing this critical condition. Notably, the therapy has been shown to exert these benefits without harmful impacts on renal function and exhibits a generally favorable safety profile.

Istaroxime, which is in the midst of four positive Phase 2 trials, is a first-in-class dual-mechanism therapy that enhances myocardial contraction and promotes cardiac relaxation. The intravenous administration of istaroxime has been found to significantly improve cardiac function and blood pressure without increasing heart rate or causing cardiac rhythm disturbances in subjects with early cardiogenic shock due to acute heart failure.

Dr. Steve Simonson, CMO and SVP of Windtree, expressed optimism about the potential of istaroxime, citing the substantial unmet need for effective treatments in the cardiogenic shock patient population. He highlighted the unique profile of istaroxime effects and the positive results from early cardiogenic shock studies as reasons to prioritize this indication for further development.

Windtree Therapeutics is committed to advancing istaroxime towards Phase 3 trials for cardiogenic shock. The company’s broader portfolio includes other product candidates in various stages of development, targeting heart failure and oncology applications. InvestingPro analysis reveals that while the company holds more cash than debt on its balance sheet, it is quickly burning through its cash reserves, with an EBITDA of -$24.68 million in the last twelve months.

In other recent news, Windtree Therapeutics has been involved in a series of significant developments. The company recently enacted a reverse stock split and expanded its equity plan, a strategic move to adjust its capital structure. The shareholders approved an amendment to effect a reverse stock split of its common stock with a ratio ranging from 1-for-5 to 1-for-50, the exact details to be determined by the company’s Board of Directors. The shareholders also voted to increase the number of shares authorized for issuance under the Amended and Restated 2020 Equity Incentive Plan.

In addition, Windtree Therapeutics has adjusted the terms of its Series C Convertible Preferred Stock, reducing the conversion price per share. This change is part of the company’s strategy to modify the terms under which the preferred stock can be converted into common stock. The company also announced the appointment of Leanne Kelly to its board of directors. Kelly, with her extensive experience in finance within the life science, technology, and e-commerce sectors, is expected to contribute to the company’s financial and strategic planning.

Furthermore, Windtree Therapeutics unveiled a new corporate strategy aimed at becoming a revenue-generating entity, planning to acquire smaller firms with FDA-approved products while continuing to develop its cardiovascular and oncology pipelines. However, the company is currently facing compliance challenges with Nasdaq’s listing standards, with issues related to the majority independent board standard and the audit committee composition standard. The company is exploring options to regain compliance within the grace periods provided by Nasdaq.
