- Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract affecting 1 in 100 Americans (around 2.4 million people) that can lead to disabling bowel symptoms and progressive bowel damage.
- Study provides direct evidence that NLRP3 signaling is over-activated in IBD, and that its inhibition attenuates intestinal inflammation and tissue damage, leading to significant improvements in IBD symptoms, and restoration of normal intestinal microbial flora.
- ZyVersa is developing Inflammasome ASC Inhibitor IC 100 which can inhibit up to 12 different inflammasomes (including NLRP3 inflammasomes) and their associated ASC specks which perpetuate damaging inflammation.
WESTON, Fla., Nov. 09, 2023 (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 publication of an article in the peer-reviewed Biomedical Journal demonstrating that inhibiting NLRP3 inflammasomes in an IBD animal model attenuates intestinal inflammation and tissue damage, leading to significant improvements in IBD symptoms, and restoration of normal intestinal microbial flora.
In the paper titled, “Inhibition of NLRP3 attenuates sodium dextran sulfate-induced inflammatory bowel disease through gut microbiota regulation,” the authors evaluated human colon biopsy samples from patients with IBD and healthy controls, and conducted a study in an IBD mouse model. Following are key findings reported in the paper:
- NLRP3 and IL-1β expression is increased in the colon of IBD patients.
- NLRP3 inhibition in the IBD animal model:
- Inhibited NLRP3 inflammasome signaling in the colon, resulting in significantly reduced levels of the pro-inflammatory cytokines IL-1b, IL-6, and TNF-α.
- Alleviated severe diarrhea and significantly improved IBD symptoms, based on the disease activity index score.
- Attenuated histopathological changes indicative of tissue damage (goblet cell reduction, crypt destruction, and epithelial barrier disruption).
- Restored gut microbiota to normal.
The authors stated, “In conclusion, this study provides direct evidence that NLRP3 signaling is over-activated in IBD patients. The inhibition of NLRP3 reverses the IBD-like symptoms in DSS-induced mice, which the regulatory effects on gut microbiota might mediate. Overall, this present study provides a basis for the clinical application of NLRP3 as a target for IBD treatment.” To read the article, Click Here.
“Restoration of quality of life is the ultimate long-term goal in IBD management. Although disease remission can often be achieved with current therapies, bothersome symptoms can still prevail,” stated Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO and President. “The research published in the Biomedical Journal provides support for inflammasome inhibition as a promising treatment option for IBD. ZyVersa is developing Inflammasome ASC inhibitor IC 100. Unlike NLRP3 inhibitors, designed to inhibit formation of one inflammasome to block initiation of the inflammatory cascade, IC 100 was designed to inhibit multiple types of inflammasomes and their associated ASC specks to uniquely block both initiation and perpetuation of damaging inflammation, which we believe is necessary to control chronic 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.
