Business: Tengion, a clinical-stage regenerative medicine company, is focused on discovering, developing, manufacturing and commercializing a range of neo-organs, or products composed of living cells, with or without synthetic or natural materials, implanted or injected into the body to engraft into, regenerate, or replace a damaged tissue or organ. Using its Organ Regeneration Platform™, the Company creates neo-organs using a patient's own cells, or autologous cells. Tengion's proprietary product candidates harness the intrinsic regenerative pathways of the body to regenerate a range of native-like organs and tissues. The Company's product candidates are intended to delay or eliminate the need for chronic disease therapies, organ transplantation, and the administration of anti-rejection medications. An initial clinical trial is ongoing for the Company's lead product candidate, the Neo-Urinary Conduit™, an autologous implant that is intended to catalyze regeneration of native-like bladder tissue for bladder cancer patients requiring a urinary diversion following bladder removal. The Company's lead preclinical candidate is the Neo-Kidney Augment™, which is designed to prevent or delay dialysis by increasing renal function in patients with advanced chronic kidney disease. Tengion has worldwide rights to its product candidates.
