About
Generation Bio is a biotechnology company that developed a T cell-selective cell-targeted lipid nanoparticle (ctLNP) platform to deliver siRNA in vivo, enabling modulation of T cell activity that causes inflammation and auto-reactive tissue destruction. Founded in 2016 and headquartered in Cambridge, Massachusetts, the company went public and subsequently underwent a phased restructuring before being acquired by XOMA Royalty in February 2026. Its ctLNP delivery system achieved the first-ever selective delivery of siRNA to T cells in non-human primates.
