GentiBio is a clinical-stage biotechnology company in Cambridge, Massachusetts building engineered regulatory T cell (EngTreg) therapies designed to restore immune tolerance and durably treat autoimmune, autoinflammatory, alloimmune, and allergic diseases. Spun out of research from Seattle Children's, Benaroya Research Institute, and MIGAL Galilee Research Institute, the company combines gene editing of FOXP3 with a modular Treg engineering and manufacturing platform. Its lead program, GNTI-122, is an autologous antigen-specific Treg therapy for recently diagnosed type 1 diabetes now in a Phase 1 trial (POLARIS). GentiBio has raised roughly $177M and signed a partnership with Bristol Myers Squibb worth up to $1.9B in potential milestones.
Kira Biotech is a Brisbane-based clinical-stage immunology company developing first-in-class antibody therapeutics that retrain the immune system instead of broadly suppressing it. Its lead candidate, KB312, selectively depletes activated immune cells to restore immune tolerance, aiming to treat difficult autoimmune and inflammatory conditions such as rheumatoid arthritis, lupus, type 1 diabetes, and graft-versus-host disease. Built on decades of dendritic-cell research from Australian institutes and led by US rheumatologist Dr Dan Baker, the company launched with a A$20 million Series A in 2019 led by OneVentures and IP Group.
