American Marconi Wireless News - Revelation Biosciences Inc. Presents Additional Positive Data from Prime Clinical Study

SAN DIEGO, CA / ACCESS Newswire / March 30, 2026 / Revelation Biosciences, Inc. (NASDAQ:REVB) (the "Company" or "Revelation"), a clinical-stage life sciences company focused on innovative solutions for acute and chronic disease, presented additional positive data analysis from the PRIME Study at the International Conference on Advances in Critical Care Nephrology (AKI & CRRT 2026) in San Diego (March 29 - April 1, 2026). Presented datademonstrated the capability of Gemini to normalize the hyperinflammatory state and restore immunocompetence up to 7 days after a single dose, in stage 3 and 4 chronic kidney disease (CKD) patients peripheral blood mononuclear cells. Gemini is the Company's proprietary formulation of phosphorylated hexaacyl disaccharide, a toll-like receptor 4 agonist, in development for the treatment of acute and chronic inflammation-driven diseases such as acute kidney injury (AKI) and CKD.

In the PRIME study, a majority of patients (>85%) had at least one elevated cytokine predose and (>60%) of these patients had elevated inflammatory cytokines IL-1b and IL-6. Treatment with Gemini significantly reduced the number of elevated cytokines at all measured timepoints post-dose out to 7 days (p60%) of patients were also found to be non-responsive to stimulation (immunoparalysis) predose. Gemini significantly restored normal responsiveness to LPS stimulation (p

Acute and chronic inflammatory disease is driven by increased cytokine production, as a result of activation of innate immune cells. This dysregulation in cellular activity contributes to perpetuation and progression of disease. Data from the PRIME clinical study demonstrate that treatment with a single dose of Gemini can durably normalize inflammation at the cellular level, and restored immunocompetence.

"We are pleased to have had the opportunity to share our compelling clinical data for the treatment of inflammatory disease in this forum," said James Rolke, Chief Executive Officer of Revelation. "This engagement with key opinion leaders and health care providers treating AKI is another step in our effort to initiate our planned pivotal clinical study in AKI later this year."

About Gemini

Gemini is the Company's proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD^®), a toll-like receptor 4 (TLR4) agonist. TLR4 stimulation with Gemini rebalances the innate immune response and has been demonstrated to have the potential to treat acute and chronic diseases associated with dysregulated inflammation. Gemini is currently being evaluated as a potential treatment for acute kidney injury (GEM-AKI program) and Revelation intends to initiate a pivotal Phase 2/3 clinical study in AKI later this year. In addition to AKI, Gemini is also being developed as a treatment for chronic kidney disease (GEM-CKD program). Due to its unique biology, Gemini has the potential to be a treatment for any disease associated with dysregulated inflammation. The potential of Gemini has been demonstrated in multiple preclinical models of AKI, CKD, and infection, as well as in two phase 1 clinical studies. See additional detail here.

About AKI

Acute Kidney Injury or AKI, 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 significantly impact other organs such as the brain, heart, and lungs. Severe AKI requiring dialysis significantly increases the likelihood of worse outcomes including longer time in an ICU, potential to develop chronic kidney disease, and death.

AKI is a major cause of morbidity and mortality, affecting more than 20% of all hospitalized patients and more than 50% of patients admitted to intensive care units. Renal replacement therapy (dialysis) is still the only therapeutic option in the treatment of the consequences of severe AKI and is required in approximately 20% of all critically ill patients. Despite the fact that these patients show high mortality rates, up to 40% of patients who survive such an episode develop chronic kidney disease or end-stage renal disease. As such, new therapies to treat AKI are urgently needed.
