ZyVersa Therapeutics Highlights Data Demonstrating NLRP3 Inflammasome Inhibition Reduces Inflammation, Improves Heart Function, and Restores Glucose Homeostasis and Insulin Sensitivity in Obese Animal Model of Heart Failure (HFpEF) and Type 2 Diabetes

• Heart failure with preserved ejection fraction (HFpEF), a chronic inflammatory condition, is a leading cause of morbidity and mortality globally. Obesity, diabetes, and hypertension are highly prevalent in this population and usually precede HFpEF development.
• Authors of the published data report that the cardioprotective effects and improvements in metabolic parameters with inflammasome inhibition were correlated with reduced inflammation and macrophage activation in both cardiac and visceral adipose tissue.
• These data support the potential of ZyVersa's Inflammasome ASC Inhibitor IC 100 as an effective treatment option for patients with obesity and its associated cardiovascular and metabolic comorbidities.
• By targeting ASC, IC 100 inhibits activation of multiple inflammasome pathways activated in obesity (NLRP3, AIM2), heart failure (AIM2, NLRP3, NLRC4), and insulin resistance (AIM2, NLRP1, NLRP3, NLRC4, NLRP6). Likewise, IC 100 disrupts the function of extracellular ASC specks that perpetuate and spread inflammation to surrounding tissues leading to comorbidities.

WESTON, Fla. , March 05, 2025 (GLOBE NEWSWIRE) -- ZyVersa Therapeutics, Inc. (NASDAQ:ZVSA, or "ZyVersa")), a clinical stage specialty biopharmaceutical company developing first-in-class drugs for treatment of inflammatory and renal diseases, highlights newly published data demonstrating cardioprotective effects and improvements in metabolic parameters with inhibition of NLRP3 inflammasome pathways in an obese animal model of heart failure (HFpEF) and type 2 diabetes.

"We are excited about this data which provides further support for our selection of obesity with certain metabolic complications as the lead indication for our Inflammasome ASC Inhibitor IC 100," said Stephen C. Glover, ZyVersa's Co-founder, Chairman, CEO and President. "This comprehensive study is among the first to correlate comorbidity-driven systemic inflammation to heart disease pathogenesis. Consistent with the reported data, IC 100 protected against cardiovascular injury and dysfunction resulting from stroke-induced systemic inflammation that led to cardiac inflammation and dysfunction in a mouse model. Additionally, IC 100 has demonstrated improved insulin sensitivity and reduced fasting blood glucose in an obese mouse model of type 2 diabetic kidney disease. The premise behind development of IC 100 was to uniquely disrupt the function of extracellular ASC specks released from inflamed, injured cells that spread inflammation to surrounding tissues, perpetuating the inflammation leading to comorbidities. Likewise, by targeting ASC, IC 100 inhibits activation of multiple types of inflammasomes that are associated with pathogenesis and progression of most diseases, which we believe will lead to better control of inflammation than targeting just one inflammasome (e.g., NLRP3). We look forward to initiating two IC 100 preclinical studies in diet-induced obesity mouse models in the first half of this year. The first study will compare the effects of IC 100 to semaglutide, and the second will assess the effects of IC 100 administered concurrently with semaglutide."

The new study data were published in the peer-reviewed journal, Biomedicine & Pharmacotherapy. In the publication titled The NLRP3-inflammasome inhibitor MCC950 improves cardiac function in a HFpEF mouse model, the researchers report data from studies conducted in a mouse model that develops HFpEF and comorbidities including obesity, type 2 diabetes, and hypertension.

Key Findings

Inhibition of Inflammasome NLRP3 pathways:

• Attenuated circulating levels of pro-inflammatory cytokine, IL-18, and lowered macrophage infiltration into the heart leading to a substantial reduction in cardiac inflammation.
• Reduced cardiac hypertrophy and fibrosis, and improved cardiac diastolic function.
• Reduced fat mass, adipocyte size, and macrophage infiltration into visceral adipose tissue associated with obesity and metabolic disease.
• Improved glucose homeostasis and insulin sensitivity.

The authors concluded, "Overall, this suggests that NLRP3 inhibition could be a promising treatment for HFpEF patients with a pro-inflammatory profile, potentially improving heart function, systemic inflammation, and metabolic parameters."

About Inflammasome ASC Inhibitor IC 100

IC 100 is a novel humanized IgG4 monoclonal antibody that inhibits the inflammasome adaptor protein ASC. IC 100 was designed to attenuate both initiation and perpetuation of the inflammatory response. It does so by binding to a specific region of the ASC component of multiple types of inflammasomes, including NLRP1, NLRP2, NLRP3, NLRC4, AIM2, and Pyrin. Intracellularly, IC 100 binds to ASC monomers, inhibiting inflammasome formation, thereby blocking activation of IL-1β early in the inflammatory cascade. IC 100 also binds to ASC in ASC Specks, both intracellularly and extracellularly, further blocking activation of IL-1β and the perpetuation of the inflammatory response that is pathogenic in inflammatory diseases. Because active cytokines amplify adaptive immunity through various mechanisms, IC 100, by attenuating cytokine activation, also attenuates the adaptive immune response. The lead indication for IC 100 is obesity with certain metabolic complications. To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here.
