The Company recently announced the positive topline results from the Phase 2b study with istaroxime in acute heart failure patients with early cardiogenic shock

WARRINGTON, Pa., Oct. 09, 2024 (GLOBE NEWSWIRE) -- Windtree Therapeutics, Inc. (“Windtree” or the “Company”) (NasdaqCM: WINT), a biotechnology company focused on advancing early and late-stage innovative therapies for critical conditions and diseases, today announced the trial design of its SEISMiC Phase 2b has been published by the European Society of Cardiology Heart Failure. The article is entitled, “Safety and efficacy of up to 60 hours of intravenous istaroxime in pre-cardiogenic shock patients: Design of the SEISMiC trial.” It can be found online in Wiley Online Library DIO: 10.1002/ehf2.15102. Results can be viewed at https://ir.windtreetx.com/corporate-presentation. The Heart Failure Society of America also shared the results.

Cardiogenic shock causes high mortality and morbidity, posing challenges to the physicians treating the condition. Current drug therapies are associated with poorer outcomes and side effects. Istaroxime is a novel first-in-class investigational therapy that is intended to improve systolic contraction and diastolic relaxation of the heart while also increasing blood pressure and maintaining renal function with a generally favorable safety profile. Istaroxime has been studied in four positive Phase 2 trials enrolling patients with acute heart failure and early cardiogenic shock due to heart failure.

“This article reviews and explains key aspects of the Phase 2b trial including design, assessments and procedures, outcome measures and its endpoints,” said Dr. Steve Simonson, Chief Medical Officer and Senior Vice President at Windtree. “This clinical study approach has been the foundation for the istaroxime studies in early cardiogenic shock as well as the ongoing SEISMiC C study that is testing istaroxime in more severe SCAI Stage C cardiogenic shock patients. We are pleased with how the program is progressing toward Phase 3 readiness in cardiogenic shock.”

About Istaroxime
Istaroxime is a first-in-class dual-mechanism therapy designed to improve both systolic and diastolic cardiac function. Istaroxime is designed as a positive inotropic agent that increases myocardial contractility through inhibition of Na+/K+- ATPase with a complimentary mechanism that facilitates myocardial relaxation through activation of the SERCA2a calcium pump on the sarcoplasmic reticulum enhancing calcium reuptake from the cytoplasm. Data from multiple Phase 2 studies in patients with early cardiogenic shock or acute decompensated heart failure have demonstrated that istaroxime infused intravenously significantly improves cardiac function and blood pressure without increasing heart rate or the incidence of cardiac rhythm disturbances.
