About Tengion

Tengion, a clinical-stage regenerative medicine company, is focused on
developing its Organ Regeneration Platform™ to harness the intrinsic
regenerative pathways of the body to regenerate a range of native-like organs
and tissues with the goal of delaying or eliminating 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 most advanced product candidate, the Neo-Urinary Conduit™, an
autologous implant that is intended to catalyze regeneration of native-like
urinary 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 kidney
transplantation by increasing renal function in patients with advanced chronic
kidney disease. Tengion has worldwide rights to its product candidates.
