Windtree Therapeutics (NASDAQ: WINT) hat die Einschreibung abgeschlossen für seine SEISMiC Extension Phase 2b Studie zu istaroxime bei frühem kardio-genem Schock aufgrund von Herzinsuffizienz. Die Studie zielt darauf ab, positive Ergebnisse einer vorherigen Phase 2-Studie zu erweitern, indem die Fähigkeit von istaroxime zur Verbesserung der Herzfunktion und des Blutdrucks bewertet wird. Die Studie umfasst eine längere Dosierungsdauer und eine Dosisanpassung, wobei die wichtigsten Daten für Ende September 2024 erwartet werden.
Istaroxime ist eine neuartige Therapie der ersten Klasse, die in drei Phase 2-Studien bei akuter Herzinsuffizienz vielversprechend war. Der globale Markt für kardio-genen Schock wird auf 1,25 Milliarden Dollar jährlich geschätzt. Die in den USA, Europa und Lateinamerika durchgeführte Studie konzentriert sich auf die Dosisoptimierung und die weitere Charakterisierung des SERCA2a-Mechanismus von istaroxime bei Patienten mit frühem kardio-genem Schock.
- Completed enrollment in Phase 2b study for istaroxime in early cardiogenic shock
- Positive results from previous Phase 2 trials in improving heart function and blood pressure
- Potential to address a $1.25 billion annual global market for cardiogenic shock
- Istaroxime has not been associated with increased cardiac arrhythmias, a potential differentiator from current therapies
- Topline data not available until late September 2024
- Still in Phase 2b, indicating more studies may be needed before potential market approval
The completion of enrollment in Windtree's Phase 2b SEISMiC Extension study for istaroxime in early cardiogenic shock is a significant milestone. This study builds upon previous positive results and aims to optimize dosing strategies. Key points:
- Extended dosing duration (up to 60 hours) and dose tapering could potentially enhance efficacy
- Focus on cardiac function and safety, particularly arrhythmia risk
- Istaroxime's unique SERCA2a mechanism may offer advantages over current therapies
The study's design, targeting SCAI Stage B patients, is strategically important for positioning istaroxime in the treatment paradigm. If successful, this could address a critical unmet need in early cardiogenic shock management, potentially reducing progression to more severe stages.
Windtree's progress with istaroxime has positive implications for the company's market position:
- Cardiogenic shock market estimated at
$1.25 billion annually - Potential first-in-class therapy addressing limitations of current treatments
- Positive Phase 2 results in three trials suggest a strong foundation
The upcoming topline data in September 2024 will be a critical catalyst for Windtree's stock. Positive results could significantly enhance the company's value proposition, especially given the lack of satisfactory pharmacological interventions in this space. However, investors should be aware that Phase 2b success doesn't guarantee Phase 3 outcomes or eventual FDA approval.
Topline data anticipated in late September 2024
WARRINGTON, Pa., Sept. 04, 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 it has successfully completed enrollment in its SEISMiC Extension Phase 2b study of istaroxime in early cardiogenic shock caused by heart failure. The study is evaluating the ability of istaroxime to improve heart function and low blood pressure in the setting of early cardiogenic shock due to heart failure. The Company is looking to extend the positive results on these parameters as observed in the Company’s first SEISMiC Phase 2 clinical study that was previously reported. In addition, the Company hopes that the study results will substantiate the encouraging observations from the Company’s Phase 2 clinical study, indicating istaroxime has a favorable renal profile and does not increase cardiac arrhythmias. The SEISMiC Extension Study is utilizing longer dosing duration and tapering the dosing to assess the potential benefits.
Istaroxime is a novel first-in-class therapy that has demonstrated the ability to improve systolic contraction and diastolic relaxation of the heart while also increasing blood pressure and maintaining or improving renal function in patients with compromised cardiac function in three positive Phase 2 trials enrolling patients with acute heart failure (AHF). Cardiogenic shock is a serious condition that can occur when AHF patients continue to deteriorate and the heart cannot pump enough blood and oxygen to the brain, kidneys, and other vital organs. Mortality rates are significant and, depending on severity, range from
The SEISMiC Extension Study in cardiogenic shock was conducted in the U.S., Europe and Latin America and is expected to build upon the positive results from the Company’s first SEISMiC Phase 2 clinical study. The SEISMiC Extension Study is focused on dose optimization and additional characterization of istaroxime’s novel SERCA2a mechanism and its potential benefits in cardiogenic shock patients. The study includes hospitalized patients with early cardiogenic shock (SCAI Stage B) due to AHF and evaluates two different dose regimens of istaroxime compared to placebo. Patients received infusions of istaroxime for up to 60 hours, with one group receiving a decreasing istaroxime dose over time and the second group receiving a constant istaroxime dose. This study has extended the istaroxime dosing duration compared to previous studies where treatment was limited to 24 hours and has the potential to provide additional benefit and, along with dose titration, is an important factor in determining the optimal dosing regimen to utilize in a late-stage trial. The study is also collecting detailed information related to cardiac function and additional safety information on cardiac arrhythmias. Istaroxime has not been associated with an increase in cardiac arrhythmias, which the Company believes is a potentially important differentiating characteristic compared to commonly used current drug therapies.
“Completing enrollment in the SEISMiC Extension Study is an important step in advancing the istaroxime program to Phase 3, along with the ongoing SEISMiC C study in more severe cardiogenic shock patients” said Steve Simonson, MD, Chief Medical Officer and Senior Vice President of Windtree. “We look forward to announcing topline results from the SEISMiC Extension Study by the end of the month and plan to present this data at a major medical meeting in the very near future.”
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 cardiogenic shock or acute decompensated heart failure demonstrate that istaroxime infused intravenously significantly improves cardiac function and blood pressure without increasing heart rate or the incidence of cardiac rhythm disturbances.
