About Istaroxime Istaroxime is a first-in-class dual-mechanism therapy designed to improve both systolic and diastolic cardiac function. Istaroxime is 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 cardi ...

Core Insights - Windtree Therapeutics, Inc. announced data on istaroxime and a selective SERCA2a activator demonstrating a reduction in arrhythmias in an animal study presented at the European Society of Cardiology Heart Failure Conference [1][2] - The study focused on the activation of SERCA2a to reduce calcium-dependent arrhythmias in a rat model induced by ischemia-reperfusion, identifying a potential mechanism for decreased arrhythmias [2] Company Overview - Windtree Therapeutics is a biotechnology company aiming to generate revenue and advance innovative therapies for critical conditions, with a focus on istaroxime, a Phase 2 candidate for acute heart failure and cardiogenic shock [6] - The company is also developing preclinical SERCA2a activators and precision aPKCi inhibitors for oncology applications, alongside a licensing business model with existing partnership out-licenses [6] Product Details - Istaroxime is a first-in-class dual-mechanism therapy that enhances both systolic and diastolic cardiac function, improving myocardial contractility and facilitating myocardial relaxation through SERCA2a activation [4] - Previous Phase 2 studies indicated that intravenous istaroxime significantly improves cardiac function and blood pressure without increasing heart rate or cardiac rhythm disturbances [4] Research and Development - The current research includes evaluating preclinical product candidates for heart failure, focusing on both oral and intravenous SERCA2a activators [5]
