Welcome to OneVax, LLC

Bridging biomaterials and immunology to cure autoimmune diseases

About Us

OneVax, LLC is a pre-clinical biotechnology company located in Alachua, Florida developed to harness the intellectual and research advances of University of Florida faculty for applications in the advancement of human health, and specifically, type 1 diabetes. Members of the UF Diabetes Institute and the Department of Biomedical Engineering constitute the core membership and provide the scientific direction of the company. The initial business interests of the company involve the development of novel vaccine formulations that incorporate biomaterials and polymers for applications including multicomponent and time-release drug delivery.  The core goal of OneVax is to harness our knowledge of the immune system and biomaterials to create a tolerogenic vaccine to prevent and/or reverse type 1 diabetes.  


Our lead technology consists of non-phagocytosable MPs designed to ensure the sustained release of select tolerogenic agents to create a tolerogenic microenvironment at the site of a subcutaneous injection.  Phagocytosable MPs containing auto-antigen and tolerogenic factors are co-injected, resulting in uptake and subsequent tolerogenic presentation of auto-antigens by antigen presenting cells.  This technology has shown to prevent diabetic onset in 60% of animals in the NOD mouse model of T1D, and has successfully completed the first stage of the FDA mandated two-species pre-clinical safety studies. 

Our second technology consists of phagocytosable MPs containing auto-antigen embedded in a self-assembling hydrogel matrix loaded with tolerogenic agents, allowing for uptake and subsequent tolerogenic presentation of auto-antigens by antigen presenting cells Subcutaneous administration of this technology prevents diabetic onset in an impressive 80% of animals in the NOD mouse model of T1D.  A recently awarded Phase 1 SBIR grant from the NIH is allowing us to evaluate the pre-clinical safety of this exciting technology.   

Our final technology covalently links nanoparticles loaded with auto-antigen and tolerance inducing factors to regulatory T Cells (Tregs).  Re-introduction of modified Tregs results in the induction of a tolerogenic microenvironment, allowing for antigen presenting cells to present the auto-antigen in a tolerogenic manner. This promising technology is still in the development stage and efficacy is currently being evaluated thanks to a recently awarded Phase 1 SBIR grant and an Exploratory/Developmental Research grant (R21) from the NIH.
