Generation Bio is an innovative genetic medicines company focused on creating a new class of gene therapy to provide durable, redosable treatments for patients suffering from both rare and prevalent diseases. The company’s non-viral platform incorporates a proprietary high-capacity DNA construct called closed-ended DNA, or ceDNA; a novel cell-targeted lipid nanoparticle delivery system, or ctLNP; and an established, scalable capsid-free manufacturing process. The company is designing therapies to provide targeted delivery of genetic payloads that include large and multiple genes across a broad array of tissues, and to be redosable for individualized and extended treatment throughout a patient’s life. The platform is designed to expand access to treatments for rare diseases and to address prevalent diseases through efficient, scalable manufacturing.
