Insights
As a Financial Analyst, I find this update from Windtree Therapeutics (NASDAQ: WINT) to be moderately impactful. The company is nearing completion of enrollment for its SEISMiC Extension Phase 2b study, with topline data expected by the end of the current quarter. This is a important milestone that could potentially influence the stock's performance.
The company's progress in clinical development, particularly with istaroxime, is noteworthy. The extension of dosing duration in the current study could provide additional benefits and help determine the optimal dosing regimen for late-stage trials. This is critical for the drug's future prospects and could significantly impact the company's valuation if successful.
Furthermore, the licensing agreement with Lee's Pharmaceutical for the Greater China market, announced in January 2024, provides Windtree with potential future milestones of up to
However, investors should note that the company's ability to execute the SCAI Stage C study depends on obtaining adequate resources. This suggests potential financial constraints that could impact the company's research progress and, consequently, its stock performance.
Overall, while the clinical progress is promising, Windtree's financial position and its ability to fund ongoing research will be important factors for investors to monitor in the coming months.
From a Medical Research Analyst's perspective, Windtree Therapeutics' update on istaroxime's clinical development is significant. The SEISMiC Extension Study in SCAI Stage B early cardiogenic shock patients is particularly noteworthy, as it aims to optimize dosing and further characterize SERCA2a effects for Phase 3 planning.
The extension of dosing duration from 24 hours in the previous study to up to 60 hours in the current study is a important development. This could potentially provide additional benefits and is vital for determining the optimal dosing regimen for late-stage trials. The study's focus on detailed information related to heart function, especially associated with the SERCA2a mechanism of action, could yield valuable insights into istaroxime's efficacy.
It's important to highlight that istaroxime has not been associated with an increase in cardiac arrhythmias, which could be a significant differentiator from currently used inotropes and vasopressors. This safety profile, if maintained in larger trials, could give istaroxime a competitive edge in the market.
The planned study in more severe SCAI Stage C cardiogenic shock patients is another important development. This expansion into a more severely ill population could broaden istaroxime's potential application and market reach if successful.
However, it's important to note that these are still early-stage trials and the results, while promising, will need to be replicated in larger, Phase 3 studies before any definitive conclusions can be drawn about istaroxime's efficacy and safety profile.
Nearing completion of enrollment, the SEISMiC Extension Phase 2b study in early cardiogenic shock patients is set to deliver new data
WARRINGTON, Pa., July 25, 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 an update of istaroxime in both clinical and business development. Istaroxime is a novel first-in-class therapy that is designed to improve systolic contraction and diastolic relaxation of the heart while also increasing blood pressure and maintaining or improving renal function. It has been studied in three positive Phase 2 trials enrolling patients with acute heart failure (AHF) and early cardiogenic shock.
In line with previous guidance, the Company expects its Phase 2 SEISMiC Extension Study in SCAI Stage B early cardiogenic shock patients to complete enrollment in the next several weeks and report topline data by the end of this quarter. Building upon the positive SEISMiC study results, the Extension Study is focused on dose optimization and additional characterization of SERCA2a effects for Phase 3 planning and is expected to enroll up to 30 patients. The study of hospitalized patients with early cardiogenic shock (SCAI Stage B) due to AHF evaluates two-dose regimens of istaroxime compared to placebo. Patients will receive infusions of istaroxime for up to 60 hours, with one group receiving a decreasing istaroxime dose over time and the second group receiving a consistent istaroxime dose. This study will extend the dosing duration compared to the previous positive SEISMiC study, in which study treatment was limited to 24 hours. The Company believes extending the dosing duration of istaroxime has the potential to provide additional benefit and, along with dose titration, is an important factor in determining the optimal dosing regimen to study in late-stage trials. The study is also collecting detailed information related to heart function, particularly associated with the SERCA2a mechanism of action. Istaroxime has not been associated with an increase in cardiac arrhythmias, which the Company believes is a potentially important differentiating characteristic compared to currently used inotropes and vasopressors.
Further, the Extension Study is measuring the effects of istaroxime on blood pressure and cardiac function with the two dosing regimens similar to the improvements seen in the previous SEISMiC study.
The Company is also progressing the start-up of a parallel study in more severe, SCAI Stage C cardiogenic shock patients. SCAI stage C is a more severely ill population than was previously studied in the SEISMiC study. SEISMiC C data will be reviewed after enrollment of up to 20 patients with SCAI Stage C cardiogenic shock due to acute decompensated heart failure. It will be a placebo controlled, double-blinded study with istaroxime being added to current standard of care using inotropes or vasopressors. The effect of istaroxime in addition to these therapies will be assessed for 6 hours followed by withdrawal of the standard of care therapies. The primary endpoint is assessment of systolic blood pressure (SBP) area under the curve over the first 6 hours of treatment. Other key study measurements include: SBP changes at specified timepoints, the vasopressor-inotrope score, progression to SCAI Stage D or E cardiogenic shock, time to treatment failure, arrhythmia assessments, days alive and out of the hospital through day 30, physiologic measures (e.g., cardiac index) and length of stay in the ICU and hospital. The execution of this study will depend on the Company’s ability to obtain adequate resources for its completion.
Finally, the Company announced in January 2024 it entered into a license agreement with Lee’s Pharmaceutical (HK) Limited (“Lee’s”) for the development and commercialization of istaroxime in Greater China, including for AHF and cardiogenic shock. In addition to istaroxime, the agreement also licenses Windtree’s preclinical next-generation dual mechanism SERCA2a activators, and rostafuroxin, a Phase 2 product candidate for hypertension associated with specific genotypes. The agreement provides Windtree potential future milestones up to
“We are pleased with our progress in clinical development because of the importance of the high unmet needs in the patient populations we are studying,” said Craig Fraser, CEO and Chairman of Windtree Therapeutics. “Additionally, we are pleased that we have a licensing partner in Lee’s who can help us progress our program in acute heart failure with their resources. We look forward to reporting the topline Extension Study results later this quarter and, with additional resources, continuing our progress with SCAI Stage C study and preparations for Phase 3 readiness.”
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.
