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 Glycosylation 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 is initially developing therapies for cardiovascular and kidney diseases in older or diabetic individuals. Alteon has created a library of novel classes of compounds targeting the A.G.E. Pathway. These include A.G.E. Crosslink Breakers, A.G.E. Formation Inhibitors and Glucose Lowering Agents. The Company's lead A.G.E. Crosslink Breaker, ALT-711, is being evaluated in the Phase IIb SAPPHIRE clinical trial focused on patients with systolic hypertension, the Phase IIb SILVER trial in patients with systolic hypertension and left ventricular hypertrophy, and the Phase IIa DIAMOND trial in patients with diastolic heart failure. Other A.G.E. compounds are being evaluated for skin aging and additional indications. For more information on Alteon, visit the Company's web site at alteon.com .
