Obesity, which affects over 1.9 billion people worldwide, is a state of low-grade chronic inflammation that causes an array of different metabolic disorders, including insulin resistance, type 2 Diabetes, hypertension, cardiovascular disease, dyslipidemia, and even cancer.The article summarizes data demonstrating that inflammasome activation in fat tissue triggers cell death, known as pyroptosis. Pyroptosis results in systemic release of inflammatory cytokines, IL-1β and IL-18, and ASC specks, which perpetuates and spreads inflammation to other tissues leading to the metabolic disturbances associated with obesity.ZyVersa is developing Inflammasome ASC Inhibitor IC 100, designed to inhibit formation of multiple types of inflammasomes and their associated ASC specks to attenuate initiation and perpetuation of damaging inflammation. WESTON, Fla., Feb. 28, 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, highlights data published in Nature reinforcing IC 100’s rationale for inhibiting ASC and ASC Specks to attenuate damaging inflammation associated with various conditions, including obesity and its complications. Studies dating back to 2011 have implicated a pathogenic role for inflammasome activation in initiation of obesity and its metabolic complications. Authors of the review paper published in Nature titled, “Cell death and inflammation during obesity: Know my methods, WAT(son),” reviewed 111 papers, which demonstrated that the state of low-grade chronic inflammation in obesity combined with activated macrophages in adipose tissue result in a vicious cycle of inflammation, cell death, and metabolic dysbalance that together cause metabolic syndromes. This also promotes a pro-tumorigenic microenvironment that induces or supports tumor growth in cancers linked to obesity such as breast, liver, and colon carcinomas. The authors concluded, “There is no question that macrophage-inflammasome activation triggers systemic inflammation during obesity and it is one of the main culprits of metabolic syndromes.” To read the article, Click Here. “Obesity, a well-established risk factor for array of different metabolic disorders, including insulin resistance, type 2 Diabetes, hypertension, cardiovascular disease, and cancer, has reached pandemic proportions, and may affect up to two-thirds of the adult population in developed countries,” stated Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO and President. “The research published in Nature demonstrates that inflammasome activation in fat tissue triggers cell death. Cell death results in systemic release of inflammatory cytokines, IL-1β and IL-18, and ASC specks, which can perpetuate and spread inflammation to other tissues leading to the metabolic disturbances associated with obesity. This provides support for Inflammasome ASC Inhibitor IC 100 as a potential therapeutic option. By inhibiting ASC, IC 100 blocks formation of NLRP3 and other types of inflammasomes to block initiation of the inflammatory cascade. Likewise, IC 100 uniquely inhibits ASC specks to attenuate spread and perpetuation of damaging inflammation.” To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here. 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, 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.

Up to 16 million adults in the US are living with a neurological disease, the leading cause of physical and cognitive disability, and 1.2 million new cases are diagnosed annually. The review article summarizes data demonstrating that inflammation resulting from activation of more than one type of inflammasome contributes to development of neurological diseases and that ASC specks lead to their progression. ZyVersa is developing IC 100, a monoclonal antibody targeting inflammasome ASC and ASC specks from multiple types of inflammasomes to block initiation and perpetuation of damaging inflammation. IC 100 preclinical data demonstrate that it penetrates the brain, and that it has promising therapeutic potential for neurological diseases based on preclinical studies representative of multiple sclerosis, Alzheimer’s disease, traumatic brain injury, and spinal cord injury. WESTON, Fla., Feb. 14, 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, highlights data from a review article published in Nature Reviews Neurology. This article provides increasing evidence that activation of several types of inflammasomes and extracellular ASC specks contribute to the development and progression of multiple neurological diseases including Alzheimer’s disease (AD), Parkinson’s disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), epilepsy, traumatic brain injury (TBI), and stroke. In the paper titled, “Inflammasomes in neurological disorders — mechanisms and therapeutic potential,” the authors reviewed 297 published papers that included data from cell cultures, preclinical disease models, and human tissue analysis to summarize the current evidence for and understanding of inflammasome activation in various neurological diseases. Key learnings include: Many neurological conditions involve an underlying chronic inflammasome-mediated inflammatory process that worsens the trajectory of these conditions. Beyond NLRP3, evidence suggests that other inflammasomes, including but not restricted to NLRP1, NLRC4, and AIM2, and their downstream effectors contribute to neuropathology in AD, PD, ALS, MS, stroke, epilepsy, and TBI. Inflammasome-induced release of ASC specks into the extracellular space seems to be important in the speed of neurodegeneration in conditions such as AD and PD. The authors concluded, “Use of inflammasome-targeted therapeutic approaches could improve existing therapeutic strategies for multiple neurological conditions.” To review the publication, Click Here. “We are thrilled to see the large number of studies summarized in the review article published in Nature Reviews Neurology that reinforce the role of multiple types of inflammasomes and extracellular ASC specks in the development and progression of numerous neurological diseases,” commented Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO, and President. These studies, in combination with our own preclinical program, substantiate the rationale for targeting inflammasome ASC to inhibit multiple inflammasome pathways and to disrupt the function of ASC specks to control inflammation in numerous neurological diseases.” To review a white paper summarizing the mechanism of action and preclinical data for IC 100, Click Here.
