"With a strong product pipeline including product candidates that are being designed to address large, unmet medical needs, additional capital and a new company name, we believe the Company is well positioned to continue its work towards offering targeted therapy approaches in the treatment of diabetes," said Berkowitz, M.D., Ph.D., President and Chief Executive Officer. About Alteon Alteon is a biopharmaceutical company developing small molecule drugs to treat and prevent cardiovascular disease and to treat nephropathy in people with diabetes. The Company has identified several product candidates that it believes represent novel approaches to some of the largest pharmaceutical markets. The Company's portfolio includes orally bioavailable, organoselenium mimics of glutathione peroxidase. These compounds metabolize lipid peroxides and have the potential to limit myocardial damage subsequent to a myocardial infarction. Alteon's lead compound for that program, ALT-2074, is in Phase 2 clinical trials. The Company also has rights to uses of haptoglobin characterization. The Company is developing a clinical diagnostic test that can be used to identify patients at high risk for cardiovascular complications of diabetes and other diseases based on haptoglobin typing. Alteon also is developing alagebrium, a proposed breaker of Advanced Glycation End-Products (A.G.E.s), for the treatment of diastolic heart failure. This disease represents a rapidly growing market of unmet medical need, particularly common among diabetic patients. Alagebrium has demonstrated relevant clinical activity in two Phase 2 clinical trials in heart failure, as well as in animal models of heart failure and nephropathy, among others. Alagebrium has been tested in approximately 1,000 patients in multiple Phase 1 and Phase 2 clinical trials, allowing Alteon to assemble a sizeable human safety database.
