IC 100 has broad tissue distribution, including CNS and peripheral tissues, is rapidly internalized by a variety of cell types, binds to intracellular ASC blocking inflammasome activation, and binds to ASC specks altering ASC speck architecture and function
WESTON, Fla. and BRIDGEWATER, N.J., Aug. 3, 2022 /PRNewswire/ -- ZyVersa Therapeutics, Inc., (ZyVersa) a clinical stage specialty biopharmaceutical company developing first-in-class drugs for treatment of inflammatory and renal diseases, and Larkspur Health Acquisition Corp. (NASDAQ: LSPR or "Larkspur"), a blank-check special purpose acquisition company are pleased to announce that Translational Research has published data highlighting the differentiated mechanism of action of ZyVersa's Inflammasome ASC Inhibitor, IC 100. This research was conducted by renowned scientists from the University of Miami Miller School of Medicine, Drs. Robert W. Keane and Juan Pablo de Rivero Vaccari.
"Inflammasome dysregulation underlies the pathophysiology of many inflammatory conditions and diseases," stated Dr. Robert W. Keane, Professor, Physiology and Biophysics, Neurological Surgery and Microbiology, and Immunology, University of Miami Miller School of Medicine. "We developed a mAb, IC 100, to specifically inhibit inflammasome ASC, which is central to formation and activation of different inflammasome complexes. Upon inflammasome formation, ASC oligomerizes to form a signaling platform, the ASC speck, which activates IL-1β to initiate an inflammatory cascade. ASC specks are released from cells by pyroptosis, where they accumulate in inflamed tissues or are internalized by neighboring cells thereby perpetuating the inflammatory response."
Dr. Keane continued, "Our data published in Translational Research demonstrate that IC 100 gains access into cells and binds to ASC, and also alters the structure of ASC specks, inhibiting activation and release of IL-1 β to attenuate this process. We believe that based on this unique mechanism of action, IC 100 has potential to broadly downregulate inflammation independent of the ligands and sensors involved and effectively treat the heightened inflammatory response contributing to a multitude of diseases and conditions."
"We are especially excited about the diverse range of inflammatory diseases that IC 100 has potential to treat", indicated Dr, Juan Pablo de Rivero Vaccari, Associate Professor, Department of Neurological Surgery and The Miami Project to Cure Paralysis, and Distinguished Faculty Member of the Center for Cognitive Neuroscience and Aging at the University of Miami Miller School of Medicine. "Our newly published data reveal that IC 100 penetrates both the CNS (brain and spinal cord) and peripheral tissues (heart, lungs, kidneys, and liver). Likewise, our previous work has demonstrated the therapeutic potential of inhibiting ASC in animal models representing a variety of diseases, including multiple sclerosis, acute respiratory distress syndrome, traumatic brain injury, spinal cord injury, and age-related inflammation associated with conditions such as Alzheimer's disease."

IC 100 is a novel humanized IgG4 monoclonal antibody that inhibits the inflammasome adaptor protein ASC. IC 100 attenuates 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.
