What Revelation Biosciences does

Revelation Biosciences, Inc. is a clinical-stage life science company focused on rebalancing inflammation with Gemini, its proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD), an established Toll-like receptor 4 agonist. Its lead programs focus on kidney disorders. GEM-AKI is being evaluated as a treatment for acute kidney injury, where the text says the only current treatment is supportive care and renal replacement therapy. The company met with the FDA at the end of 2025 and agreed on a single Phase 2/3 adaptive design study with a primary composite endpoint of death and/or dialysis, to support a new drug application. GEM-CKD is being evaluated as a long-term treatment for chronic kidney disease, and the company plans preclinical toxicology studies in 2026 to support a repeat-dose Phase 2 study. The company may also pursue out-licensing and academic collaborations for Gemini in other conditions. Revelation is based in San Diego, California, and its stock is listed on Nasdaq under the ticker REVB.
