SAN DIEGO--(BUSINESS WIRE)-- Revelation Biosciences, Inc. (NASDAQ: REVB) (the 'Company' or 'Revelation'), a clinical-stage life sciences company focused on rebalancing inflammation to optimize health, today announced dosing has been completed for the PRIME (PReconditioning IMmunostimulatory Evaluation) Phase 1b clinical study of escalating doses of intravenously administered Gemini in patients with Stage 3 and 4 Chronic Kidney Disease (CKD).
As planned, a total of 5 cohorts were enrolled at 3 clinics in the United States. Several study data sets are expected during Q3 2025: these will include safety parameters, changes in hematologic parameters, in vitro evaluation of the inflammatory response in peripheral blood mononuclear cells isolated from study participants, and multiple biomarkers of activity.
'We thank our Investigators and participants for the rapid completion of dosing,' said James Rolke, Chief Executive Officer of Revelation. 'We are looking forward to sharing the study data shortly, and engaging the FDA to discuss future clinical development and approval pathways later this year.'
About Gemini
Gemini is an intravenously administered, proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD ®) that reduces the damage associated with inflammation by reprograming the innate immune system to respond to stress (trauma, infection, etc.) in an attenuated manner.
Gemini 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), or infection post severe burn (GEMINI-PBI). Gemini may also be a treatment to stop or slow the progression of chronic kidney disease (GEMINI-CKD program).
Revelation has conducted multiple preclinical studies demonstrating the therapeutic potential of Gemini in the target indications. Revelation previously announced 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.
About CKD
Chronic kidney disease is a pervasive problem in the United States and world-wide. CKD is caused by 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 – it creates 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 that results in CKD. Other risk factors include heart disease, obesity, family history of CKD, or advanced 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 disease is a leading cause of death in the United States.
About AKI
AKI, also known as acute renal failure, is a rapid loss of kidney function. AKI causes a build-up of waste products in the blood, making 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, the heart, and the lungs.
