Tengion, Inc., a regenerative medicine company, focuses on discovering, developing, manufacturing, and commercializing a range of replacement organs and tissues, or neo-organs and neo-tissues to address unmet medical needs in urologic, renal, gastrointestinal and vascular diseases. It creates these functional neo-organs and neo-tissues using a patient's own cells, or autologous cells, in conjunction with the company's Organ Regeneration Platform. The company's lead product candidate, the Neo-Urinary Conduit, is an autologous implant that catalyzes regeneration of native-like bladder tissue for bladder cancer patients requiring a urinary diversion following bladder removal, or cystectomy. Its product pipeline also includes various candidates in early stage development, such as Neo-Kidney Augment for patients with advanced chronic kidney disease, or CKD. The company was founded in 2003 and is headquartered in East Norriton, Pennsylvania.
