Windtree Announces Notice of Allowance from the US Patent and Trademark Office for a New Istaroxime Patent
Oct 25, 2021
The istaroxime patent application is entitled, “Istaroxime-Containing Intravenous Formulation for the Treatment of Acute Heart Failure (AHF),” and was the result of an expedited US
“We continue to strengthen the istaroxime patent estate and look forward to the anticipated issuance of this patent from the USPTO,” said
Windtree plans to start the next acute heart failure study by mid-2022. This study will target AHF patients with normal to low blood pressure and look to optimize istaroxime dosing by employing a longer infusion duration. The primary endpoint will be echocardiographic assessment of cardiac function (similar to the 2b study). It will also include as secondary endpoints, assessments that could potentially become primary pivotal endpoints in the Phase 3 program and thus put the program in what the company believes will be a good Phase 3 ready and partnership position. In the meantime, the company is also conducting a Phase 2 study in early cardiogenic shock patients with results expected in the first quarter of 2022.
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 complementary 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 acute heart failure (AHF) demonstrate that istaroxime infused intravenously significantly improves cardiac function and blood pressure without causing heart rate increases or rhythm disturbances.
