Windtree Announces Publication on its SERCA2a Activator Drug Candidate for Chronic and Acute Heart Failure
Windtree Therapeutics (NasdaqCM: WINT) announced that its SERCA2a activators were featured in a publication in The Journal of Pharmacology and Experimental Therapeutics. This highlights the potential of these drugs in treating heart failure by selectively targeting SERCA2a, which plays a crucial role in calcium management in heart muscles. The company emphasized the promising results from human clinical trials for its lead compound, istaroxime, which has shown positive outcomes in phase 2 studies for acute heart failure. Additionally, the USPTO published a new patent application related to SERCA2a activators, enhancing Windtree's intellectual property portfolio.

WARRINGTON, Pa., Feb. 28, 2023 (GLOBE NEWSWIRE) -- Windtree Therapeutics, Inc. (“Windtree” or the “Company”) (NasdaqCM: WINT), a biotechnology company focused on advancing multiple late-stage interventions for cardiovascular disorders, announced that its preclinical stage drug candidates called SERCA2a Activators were featured in a publication in The Journal of Pharmacology and Experimental Therapeutics entitled “Istaroxime Metabolite PST3093 Selectively Stimulates SERCA2a and Reverses Disease-Induced Changes in Cardiac Function.”
Heart failure is a complex and heterogeneous condition and involves impaired ability of the heart to contract (systolic) and/or relax (diastolic function). The publication emphasizes the interest in SERCA2a as a target in treating heart failure because it is instrumental in calcium management, critically important in heart muscle contraction and relaxation. Abnormalities in the handling of calcium can facilitate arrhythmias and may contribute to poor myocardial remodeling as the disease progresses. Our SERCA2a activators uniquely interfere with phospholamban, a protein that inhibits SERCA2a function and does so excessively in heart failure. The preclinical data discussed in the paper provides rationale for selective targeting of SERCA2A in the treatment of heart failure.
“Windtree’s SERCA2a activator drug candidates could represent a promising IV or oral approach to treat heart failure,” said Steve Simonson, CMO of Windtree Therapeutics. “SERCA2a activation has been an attractive but elusive approach for the treatment of heart failure for many years. It has been difficult to achieve, however, our approach to relieve the inhibition of SERCA2a by phospholamban has provided a potentially successful mechanism to achieve this goal. Human clinical data emerging from the istaroxime program is substantiating this approach and providing unique insight into the potential benefits of this mechanism in humans. Istaroxime has completed three positive phase 2 clinical studies in acute decompensated heart failure and early cardiogenic shock. This experience may provide a better probability for clinical success in the development of SERCA2a activators as they advance.”
Additionally, the USPTO published the Company’s SERCA2a Activator patent application entitled “Androstane Derivatives with Activity as Pure or Predominantly Pure Stimulators of SERCA2a for the Treatment of Heart Failure.” The Publication No is US-2023-0009312-AI.
About Pure SERCA2a Activators
Sarco endoplasmic reticulum Ca2+ -ATPase 2a, or SERCA2a, activators increase SERCA2a activity. The Windtree research program is evaluating these preclinical product candidates as oral and intravenous SERCA2a activator heart failure compounds. As potential oral agents, these candidates could be used for chronic treatment of heart failure.
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 causing heart rate increases or 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.
