ZVSA ZyVersa Therapeutics Inc

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 newly published data demonstrating that stroke-related cardiovascular injury and dysfunction is induced by AIM2 inflammasome activation and pyroptosis in the heart, which can be blocked by Inflammasome ASC Inhibitor IC 100.

“These data demonstrate the potential for IC 100 to attenuate stroke-related cardiovascular disease which is common in patients living with obesity. According to the American Heart Association, obesity-related cardiovascular disease deaths tripled between 1999 and 2020, and this is expected to continue to increase without effective therapeutic options,” said Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO and President. “We are excited about the potential of IC 100 to effectively control the inflammation that drives stroke-related cardiovascular injury and dysfunction. Unlike the NLRP3 inhibitors in development, IC 100 targets ASC to inhibit activation of multiple inflammasomes, including AIM2, which triggered the systemic inflammatory response affecting the heart after stroke in this study. More importantly, IC 100 uniquely disrupts the function of ASC specks to attenuate chronic, systemic inflammation leading to comorbidities. We look forward to progressing IC 100’s development program into phase 1 around mid-2025.

This study was published in the peer-reviewed journal, Translational Stroke Research, by acclaimed inflammasome researchers from the University of Miami Miller School of Medicine and inventors of IC 100. In the publication titled, Catecholamine‑Induced Inflammasome Activation in the Heart Following Photothrombotic Stroke, the researchers report data from studies conducted in a mouse model of photothrombotic stroke (PTS) and in excised zebrafish hearts.

Key Findings

• PTS in mice results in activation of the AIM2 inflammasome in the heart resulting in significant increases in IL-1β and ASC oligomerization into ASC specks contributing to a systemic inflammatory response affecting the heart after stroke.
• Treatment with IC 100 (30 mg/kg) at 30 minutes post-PTS significantly reduced the levels of inflammasome proteins and IL-1β in the heart thus reducing cardiac inflammation.
• Epinephrine-treated zebrafish hearts demonstrated a shortened action potential duration (SAPD) which was attenuated by IC 100. SAPD can cause irregular heart rhythm and reduced cardiac efficiency commonly seen in strokes and heart failure.

“These findings indicate that stroke initiates a catecholamine surge that induces inflammasome activation and pyroptosis in the heart that is blocked by IC 100, thus providing a framework for the development of therapeutics for stroke-related cardiovascular injury,” stated author Dr. Robert W. Keane, Professor, Physiology and Biophysics, Neurological Surgery and Microbiology, and Immunology, University of Miami Miller School of Medicine.

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.
