About Alteon

Alteon is developing several new classes of drugs that reverse or slow down
diseases of aging and complications of diabetes.  These compounds have an
impact on a fundamental pathological process caused by protein-glucose
complexes called Advanced Glycation End-products (A.G.E.s).  The formation and
crosslinking of A.G.E.s lead to a loss of flexibility and function in body
tissues, organs and vessels and have been shown to be a causative factor in
many age-related diseases and diabetic complications.  Alteon has created a
library of novel classes of compounds targeting the A.G.E. Pathway.  Alteon's
lead compound alagebrium chloride (formerly ALT-711), the only A.G.E. Crosslink
Breaker in advanced human testing, has demonstrated safety and efficacy in
several Phase 2 trials and is actively being developed for systolic
hypertension and heart failure.  Ongoing clinical trials include SPECTRA
(Systolic Pressure Efficacy and Safety Trial of Alagebrium) and PEDESTAL
(Patients with Impaired Ejection Fraction and Diastolic Dysfunction: Efficacy
and Safety Trial of ALagebrium), as well as a third trial exploring mechanism
of action in endothelial dysfunction.  For more information on Alteon, visit
