Data demonstrate that extracellular ASC specks, independent of IL-1β, govern the pathogenesis and extent of amyloid A (AA) amyloidosis, which is characterized by deposition of insoluble amyloid fibrils in tissues and organs disrupting their structure and function.Extracellular ASC interacts with serum amyloid A (SAA) released by the liver during inflammation, forming a scaffold that accelerates SAA aggregation into amyloid fibrils, which are deposited in tissues and organs.Amyloid A amyloidosis occurs in a heterogeneous spectrum of chronic inflammatory conditions such as rheumatoid arthritis, Crohn’s disease, and inflammatory bowel disease.ZyVersa is developing Inflammasome ASC Inhibitor IC 100, which inhibits intra- and extracellular ASC and specks associated with multiple types of inflammasomes to attenuate damaging inflammation and its perpetuation and spread to surrounding tissues. WESTON, Fla., Aug. 07, 2024 (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, announces data published in the peer-reviewed journal, EMBO Molecular Medicine, demonstrating that extracellular ASC has a crucial role in aggregation and deposition of amyloid A fibrils leading to associated chronic inflammatory conditions. “This research highlighting the role of extracellular ASC specks, independent of IL-1β, in the pathogenesis of chronic conditions associated with amyloid A amyloidosis reinforces our selection of ASC as a target for our inflammasome inhibitor IC 100,” stated Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO, and President. “This paper provides one more piece of evidence that inhibiting extracellular ASC specks associated with multiple types of inflammasomes has potential to control damaging inflammation associated with a broad range of inflammatory diseases.” The paper titled, The ASC inflammasome adapter governs SAA-derived protein aggregation in inflammatory amyloidosis, summarizes data from in vitro and in vivo research investigating the role of ASC in inflammation-associated amyloidosis. Following is a summary of key findings: ASC colocalized tightly with SAA in human AA amyloidosis.ASC specks accelerated SAA fibril formation.Splenic amyloid load was decreased in a Pycard knock-out mouse model of AA Amyloidosis which lacks ASC.Treatment with anti-ASCPYD antibodies decreased amyloid loads in wild-type mice suffering from AA amyloidosis. “Our findings might have therapeutic implications that advance the fields of protein misfolding disorders (PMDs) and chronic inflammatory diseases in general as ASC could be a target of disease-modifying therapies that aim to reduce amyloid deposition and pathology in various proteinopathies,” concluded the authors. 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 and its associated metabolic complications. To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here.

This data supports the potential of plasma ASC levels as a biomarker for early stages of cognitive decline, based on elevated ASC levels in older adults (>60 years) who were cognitively normal at baseline but demonstrated cognitive decline one year later (NI) compared to ASC levels in those who: Were cognitively normal at both baseline and 1 year later (NN), andWere cognitively impaired at both baseline and one year later (II) Inflammasome-induced neuroinflammation has been associated with early stages of cognitive decline in dementia associated with Alzheimer’s and Parkinson’s diseases.Excessive inflammasome activation leads to cell death (pyroptosis) and systemic release of cell contents, including ASC that can be measured in the plasma. WESTON, Fla., July 29, 2024 (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, announces that leading inflammasome researchers from the University of Miami Miller School of Medicine and inventors of Inflammasome ASC Inhibitor IC 100 have published a scientific paper in the peer-reviewed International Journal of Molecular Sciences demonstrating that plasma levels of inflammasome ASC show promise as a biomarker of early cognitive decline in older adults. “Elevations in plasma ASC in early cognitive decline reinforce the role of inflammasome-induced inflammation in the development of neurodegenerative conditions such as Alzheimer’s and Parkinson’s diseases,” stated Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO, and President. “ZyVersa is developing Inflammasome ASC Inhibitor IC 100 to inhibit multiple types of inflammasomes and their associated ASC specks that trigger damaging inflammation pathogenic in neurological and other inflammatory diseases, such as obesity and its metabolic complications, our lead indication.” The paper titled, The Inflammasome Adaptor Protein ASC in Plasma as a Biomarker of Early Cognitive Changes, summarizes biomarker assessments in older adults at baseline and at one-year follow-up. Following is a summary of key findings: Plasma ASC levels were elevated in older adults (>60 years) who were cognitively normal at baseline but demonstrated cognitive decline one year later (NI) compared to ASC levels in those who remained cognitively normal one-year post-baseline assessment (NN). The increase in ASC levels was even higher in people who were 70 years or older.Likewise, plasma ASC levels in the NI group were elevated compared to ASC levels in older adults who demonstrated cognitive impairment at both baseline and one year later (II), indicating that plasma ASC levels are increased in the early stages of cognitive decline. Again, the increase in ASC levels was even higher in people who were 70 years or older. In the group over 70 years old, area under the curve (AUC) for plasma levels of ASC in group NI versus group NN was 0.81, indicating excellent ability to differentiate between people with cognitive decline at one year versus those who were cognitively normal both at baseline and at one year. AUC is used to determine the diagnostic power of a biomarker. “Dementia affects 57 million people worldwide, and the incidence is expected to double by 2040. There is an unmet need to develop minimally invasive, reliable biomarkers to diagnose early brain impairments so that emerging interventions can be applied before brain degeneration,” said Dr. Juan Pablo de Rivero Vaccari, Associate Professor of Neurological Surgery and The Miami Project to Cure Paralysis and Distinguished Faculty of the Center for Cognitive Neuroscience and Aging at the University of Miami Miller School of Medicine. “Our data indicate that plasma levels of ASC are a strong early indicator of the eventual development of cognitive impairment, especially in persons older than 70 years.” About Inflammasome ASC Inhibitor IC 100 IC 100 is a novel humanized IgG4 monoclonal antibody that inhibits the inflammasome adaptor protein ASC.

WESTON, Fla., July 25, 2024 (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, announces that obesity and its related metabolic complications has been selected as the lead indication for Inflammasome ASC Inhibitor IC 100. “Obesity, a well-established risk factor for an array of different metabolic disorders, including insulin resistance, type 2 Diabetes, hypertension, cardiovascular disease, and cancer, has reached pandemic proportions, affecting up to two-thirds of the adult population in developed countries,” stated Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO and President. “Published research demonstrating that inflammasome activation in fat tissue triggers cell death and systemic release of proinflammatory IL-1β, and ASC specks, which can perpetuate and spread inflammation leading to metabolic disturbances associated with obesity provides support for Inflammasome ASC Inhibitor IC 100 as a potential therapeutic option. We are excited about progressing our development program in this area of high unmet needs.” Following is the rationale behind selection of obesity and related metabolic complications, and an overview of the development program. Why Obesity and Related Metabolic Complications as an Indication? Large Growing Market: The global obesity drug market reached nearly $24 billion in 2023, more than a sevenfold growth in just three years, and it is forecasted by IQVIA t to reach up to $131 Billion by 2028 (24 – 27% CAGR).Significant Health and Economic Impact: Obesity, which now affects over 40% of Americans (CDC), is associated with multiple chronic medical conditions, including type 2 diabetes, heart disease, and some forms of cancer, at an annual cost and economic impact exceeding 1.4 trillion in the United States including healthcare expenditures, loss of productivity (Milken Institute).Need for Alternative Mechanisms of Action to Complement GLP-1 agonists: While GLIP-1 drugs deliver meaningful weight loss, improve glucose control, and help to mitigate cardiovascular disease, they do not address the chronic tissue inflammation observed in adipose tissue, liver, muscle, and pancreatic islet cells that has emerged as a key feature of obesity. This chronic tissue inflammation, termed, “immunometabolism,” leads to insulin resistance, beta cell dysfunction, and development of type 2 diabetes and long-term inflammatory complications including microvascular disease (retinopathy, nephropathy, and neuropathy), macrovascular disease (stroke, myocardial infarction, and peripheral arterial disease), heart failure, and nonalcoholic fatty liver disease. As such, anti-inflammatory drugs have potential to provide additional benefits in obesity management (Immunity. 2022 Jan 11;55(1):31-55). Rationale for Inflammasome Inhibitors as a Treatment for Obesity and Related Metabolic Complications Inflammasomes, which are activated by nutrients, such as glucose and free fatty acids, trigger activation and stimulation of downstream inflammatory pathways, leading to chronic inflammation in obesity (Front Endocrinol (Lausanne). 2023 Aug 31;14:1232171). Nutrient overload triggers inflammasome-induced inflammation in the brain’s hypothalamus, causing increased appetite and food intake, increasing the number and size of fat cells associated with weight gain and obesity.The fat cells become hypoxic, resulting in cell death and macrophage recruitment. This leads to inflammasome activation, death of inflamed cells, and systemic release of proinflammatory cytokines, such as IL-1β, and ASC specks, spreading inflammation throughout the body. If unresolved, sustained inflammation leads to the metabolic complications of obesity. Why Inflammasome ASC Inhibitor IC 100? Multiple types of inflammasomes, not just NLRP3, are activated in obesity and related metabolic complications (NLRP1, NLRP3, NLRC4, and AIM2). Because IC 100 targets the inflammasome ASC component, it inhibits each of these inflammasomes, including NLRP3, with potential to better attenuate the damaging inflammation associated with obesity and its complications (Immunology. 2021 Aug;163(4):348-362).Inflammation is spread and perpetuated by systemic release of proinflammatory IL-1β and ASC specks during death of inflamed cells, leading to obesity-related complications. IC 100 disrupts the structure and function of ASC specks, thereby attenuating spread and perpetuation of inflammation (Transl Res. 2022 Jul 3:S1931-5244(22)00150-5). ZyVersa believes that inflammasome ASC Inhibitor IC 100 administered concurrently with GLIP-1 agonists will lead to incremental weight loss, and more importantly, attenuate the chronic tissue inflammation not addressed by GLIP-1 agonists to reduce the long-term micro- and macrovascular inflammatory complications. Inflammasome ASC Inhibitor IC 100 Development Plans for Obesity and Related Complications IC 100’s preclinical program is nearing completion, with a planned Investigational New Drug (IND) submission Q4-2024, and Phase 1 clinical trial initiation shortly thereafter.Preclinical scientific collaboration to assess IC 100 as a potential treatment for atherosclerosis, a common obesity-related metabolic complication, is expected to conclude H2-2024.Preclinical scientific collaboration with University of Miami Miller School of Medicine to assess IC 100 as a potential treatment for obesity and metabolic syndrome is expected to begin H2-2024, with a second study looking at concomitant treatment with IC 100 and a GLIP-1 agonist to begin shortly thereafter.ZyVersa has recruited six top-tiered experts in obesity and related metabolic complications for a scientific advisory board to guide clinical development plans for IC 100, which will be announced in the next few weeks.
