HMGB-1 is an endogenous damage associated molecular pattern (DAMP) that is generated during tissue injury (e.g. during surgery) which drives the inflammatory response. LPS is an exogenous pathogen associated molecular pattern (PAMP) that is generated from a bacterial infection and drives the inflammatory response associated with infection (e.g. fever).\n<\/p>\n \nAfter exposure of Gemini-primed PMBCs to either HMGB-1 or LPS, levels of multiple proinflammatory and anti-inflammatory cytokines including IL-1 beta, TNF-alpha, IL-6, IL-1 Receptor Antagonist, and IL-10 were measured. Priming with Gemini significantly decreased proinflammatory cytokines and significantly increased anti-inflammatory cytokines, relative to placebo. Figure 1 shows two relevant measures following HMGB-1 and LPS challenge. This fundamental change in responsiveness at the cellular level demonstrates how Gemini will protect against inflammation-mediated damage. Revelation intends to share the full results from this study in a future publication.\n<\/p>\n \nAs a part of the PRIME<\/a> (PR<\/span>econditioning IM<\/span>munostimulatory E<\/span>valuation) Phase 1b clinical study in patients with Stage 3 and 4 Chronic Kidney Disease (CKD), Revelation is collecting PBMCs from dosed patients and anticipates demonstration of the attenuated response to HMGB-1 and LPS ex vivo<\/i> relative to placebo subjects. Top-line data comprising safety, tolerability, and this demonstration of protection from relevant promotors of inflammation at a cellular level are expected by mid 2025. Data from the PRIME clinical study will support future development of the GEM-CKD<\/a>, GEM-AKI<\/a> and GEM-PSI<\/a> programs.\n<\/p>\n \n\u201cThese exciting results further demonstrate the game-changing potential of Gemini to attenuate the inflammatory response to clinically relevant DAMPS and PAMPS,\u201d said James Rolke, Chief Executive Officer of Revelation. \u201cWe look forward to demonstrating the same protective effect in cells collected from CKD patients, which will be an excellent surrogate of future efficacy of Gemini in our target indications.\u201d\n<\/p>\n About AKI<\/b><\/p>\n \nAKI, also known as acute renal failure, is defined as a rapid loss of kidney function. AKI causes a build-up of waste products in blood and makes it more difficult for kidneys to maintain the correct balance of fluid in the body. AKI can also have a significant impact on other organs such as the brain, heart, and lungs.\n<\/p>\n About CKD<\/b><\/p>\n \nChronic kidney disease is a pervasive problem in the United States and world-wide. CKD is due to chronic inflammation and can be initiated and propagated in several ways. One prevalent condition is the high blood sugar levels associated with diabetes (either Type 1 or Type 2). High blood sugar is toxic to kidney cells creating stress which imitates the inflammatory process leading to the demise of these cells with subsequent fibrosis ultimately resulting in continuous loss of kidney function over time. High arterial blood pressure is another source of stress that initiates the inflammatory process leading to CKD. Other risk factors include heart disease, obesity, family history of CKD or older age. Progression of chronic kidney damage often leads to end stage renal disease with the need for renal replacement therapy (dialysis or transplantation), resulting in significant morbidity and mortality for affected patients. Kidney diseases is a leading cause of death in the United States.\n<\/p>\n About Gemini<\/b><\/p>\n Gemini<\/a> is an intravenously administrated, proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD\u00ae<\/sup>) that reduces the damage associated with inflammation by reprogramming the innate immune system to respond to stress (trauma, infection, etc.) in an attenuated manner. Revelation has conducted multiple preclinical studies demonstrating the therapeutic potential of Gemini in the target indications. Revelation previously announced<\/a> positive Phase 1 clinical data for intravenous treatment with Gemini. The primary safety endpoint was met in the Phase 1 study, and results demonstrated statistically significant pharmacodynamic activity as observed through expected changes in multiple biomarkers including upregulation of IL-10.\n<\/p>\n \nGemini is being developed for multiple indications including as a pretreatment to prevent or reduce the severity and duration of acute kidney injury (GEMINI-AKI program), and as pretreatment to prevent or reduce the severity and duration of post-surgical infection (GEMINI-PSI program). In addition, Gemini may be a treatment to stop or slow the progression of chronic kidney disease (GEMINI-CKD program).\n<\/p>\n About Revelation Biosciences, Inc.<\/b><\/p>\n \nRevelation Biosciences, Inc. is a clinical stage life sciences company focused on harnessing the power of trained immunity for the prevention and treatment of disease using its proprietary formulation Gemini<\/a>. Revelation has multiple ongoing programs to evaluate Gemini, including as a prevention for post-surgical infection, as a prevention for acute kidney injury, and for the treatment of chronic kidney disease.\n<\/p>\n \nFor more information on Revelation, please visit www.RevBiosciences.com<\/a>.\n<\/p>\n Forward-Looking Statements<\/b><\/p>\n \nThis press release contains forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995, as amended.
