Revelation Biosciences Has Completed Dosing of its First in Human Phase 1 Clinical Study of Gemini

In This Article:

-Top-line data forthcoming-

SAN DIEGO, June 13, 2024--(BUSINESS WIRE)--Revelation Biosciences, Inc. (NASDAQ: REVB) (the "Company" or "Revelation"), a clinical-stage life sciences company that is focused on harnessing the power of trained immunity for the prevention and treatment of disease, announced today that it has completed enrollment and dosing of its first in human Phase 1 clinical study (RVL-HV02). The study, which was conducted in Australia, evaluated escalating doses of intravenously administered Gemini and enrolled 40 healthy individuals 18 to 55 years of age. The forthcoming top-line data will include primary end points of safety and tolerability along with exploratory endpoints including multiple biomarkers of activity to demonstrate stimulation of the innate immune response. If positive, the data from this Phase 1 clinical study will support future program development of Gemini across multiple indications.

Gemini is the Company’s proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD?), a toll-like receptor 4 (TLR4) agonist. TLR4 stimulation with PHAD potentially preconditions the innate immune system to respond to a subsequent stress, such as ischemia (loss of blood flow) or bacterial infection. Gemini is initially being developed for two target indications: as a pretreatment to prevent or reduce the severity of acute kidney injury (AKI) due to cardiac surgery and as a pretreatment to reduce the incidence, duration, and severity of post-surgical infection. Preclinical studies using models of AKI have demonstrated pretreatment with Gemini can reduce the severity and duration of AKI. Additionally, preclinical studies using models of bacterial infection have demonstrated pretreatment with PHAD can reduce the overall rate and severity of infection.

"We are grateful to our investigator and the participants who enrolled in this study," said James Rolke, Chief Executive Officer of Revelation. "Completion of our Phase 1 enrollment is a significant milestone for the advancement of Gemini to address multiple critical unmet needs, and we are looking forward to announcing the forthcoming topline safety and activity data soon."

About Gemini

Gemini is a proprietary formulation of phosphorylated hexaacyl disaccharide (PHAD?) for systemic administration. It is being developed for multiple indications including as a pretreatment to prevent or reduce the severity and duration of post-surgical infection (GEMINI-PSI program), as pretreatment to prevent or reduce the severity and duration of acute kidney injury (GEMINI-AKI program). In addition, Gemini may be a treatment to stop or slow the progression of chronic kidney disease (GEMINI-CKD program). Revelation believes Gemini works through trained immunity, which redirects and attenuates the innate immune response to external stress (infection, trauma, etc.). Revelation has conducted multiple preclinical studies demonstrating the therapeutic potential of Gemini in the target indications.
