ALT Ishares Diversified Alternatives Trust

MONTVALE, N.J., May 11 /PRNewswire-FirstCall/ -- Alteon Inc. (AMEX:ALT) announced today that Noah Berkwitz, MD, PhD, President and Chief Executive Officer, will deliver a corporate presentation at the Acumen BioFin Rodman & Renshaw 4th Annual Global Healthcare Conference in Monaco at 2:15 p.m. (8:15 a.m. Eastern) on Monday, May 14, 2007. About Alteon Alteon is a product-based biopharmaceutical company engaged in the development of small molecule drugs to treat and prevent the inflammatory aspects of cardiovascular disease and diabetes. The Company has identified several promising product candidates that it believes represent novel approaches to some of the largest pharmaceutical markets. Alagebrium, a product of Alteon's drug discovery and development program, is being developed 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, which represents a sizeable human safety database. The Company's portfolio also includes orally bioavailable, organoselenium mimics of glutathione peroxidase that 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 a diagnostic assay that identifies a large subset of diabetic patients at highest risk for cardiovascular complications, because of a defect in oxidized lipid metabolism that results in increased cardiovascular inflammation.
