Windtree Therapeutics Announces Issuance of New Dual Mechanism SERCA2a Activator Patent
Windtree Therapeutics (NasdaqCM: WINT) announced that the European Patent Office has granted Patent No. 3599243, protecting a class of SERCA2a Activators for heart failure treatment until July 2038. This patent covers dual mechanism drug candidates that both activate SERCA2a and inhibit the Na+/K+ pump. Unlike existing treatments, these candidates may offer both intravenous and oral therapies for acute heart failure and chronic heart failure management.
CEO Craig Fraser highlighted the significance of SERCA2a activation in advancing heart failure treatment. Windtree's platform also includes istaroxime, a first-in-class therapy that improves cardiac function.
- European Patent Office granted Patent No. 3599243 for SERCA2a Activators.
- Patent coverage extends until July 2038, securing intellectual property.
- Development of novel therapies may improve treatment options for heart failure patients.
- None.
Compounds that activate SERCA2a may lead to novel therapies for heart failure
WARRINGTON, Pa., April 17, 2023 (GLOBE NEWSWIRE) -- Windtree Therapeutics, Inc. (“Windtree” or the “Company”) (NasdaqCM: WINT), a biotechnology company focused on advancing late-stage interventions for cardiovascular disorders, today announced that the European Patent Office has granted Patent No. 3599243, providing patent coverage for the dual mechanism SERCA2a Activator class of drug candidates. Windtree has preclinical drug candidates with dual mechanisms of action (inhibition of the Na+/K+ pump and activation of SERCA2a) as well as pure SERCA2a activators (devoid of action on the Na+/K+ pump). The new patent, titled: “17BETA-HETEROCYCLYL-DIGITALIS LIKE COMPOUNDS FOR THE TREATMENT OF HEART FAILURE,” provides patent protection until July 2038 for the family of compounds with a dual mechanism of action.
Like istaroxime, the intravenous late-stage development candidate for treatment of acute decompensated heart failure and cardiogenic shock, the dual mechanism compounds activate SERCA2a and inhibit the Na+/K+ pump. However, these product candidates are intended to be both oral and IV therapies and may represent a hospital inpatient therapy for acute decompensated heart failure as well as outpatient, oral therapy for hospital discharge and chronic heart failure treatment.
“SERCA2a activity is decreased in heart failure. Windtree believes therapies that activate SERCA2a represent a potential important advancement in heart failure treatment for patients,” said Craig Fraser, CEO and President of Windtree Therapeutics. “The development strategy with these dual mechanism compounds is for potential ‘fast follow-on’ drug candidates that can leverage the experience with istaroxime and provide the potential added feature of oral bioavailability for use as a treatment for chronic heart failure. Compounds that activate SERCA2a have been aggressively pursued as much sought-after targets in the treatment of heart failure, and Windtree has found a unique mechanism that activates SERCA2a.”
About Dual Mechanism SERCA2a Activators
These compounds activate SERCA2a and inhibit the Na+/K+ pump. Windtree Therapeutic’s research program is evaluating these preclinical product candidates, including oral and intravenous SERCA2a activator heart failure compounds.
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 acute heart failure (AHF) demonstrate that istaroxime infused intravenously significantly improves cardiac function and blood pressure without increasing heart rate or the incidence of cardiac rhythm disturbances.
About Windtree Therapeutics, Inc.
Windtree Therapeutics, Inc. is advancing multiple late-stage interventions for cardiovascular disorders to treat patients in moments of crisis. Using new scientific and clinical approaches, Windtree is developing a multi-asset franchise anchored around compounds with an ability to activate SERCA2a, with lead candidate, istaroxime, being developed as a first-in-class treatment for acute heart failure and for early cardiogenic shock. Windtree’s heart failure platform includes follow-on oral pre-clinical SERCA2a activator assets as well. In pulmonary care, Windtree has focused on facilitating the transfer of the KL4 surfactant platform, to its licensee, Lee’s Pharmaceutical (HK) Ltd. Included in Windtree’s portfolio is rostafuroxin, a novel precision drug product targeting hypertensive patients with certain genetic profiles.
