Elan Corporation, plc (NYSE: ELN) today announced multiple presentations at the 2009 Alzheimer’s Association International Conference on Alzheimer’s Disease (ICAD 2009) in Vienna, Austria.

Elan and investigators will be present from the Alzheimer's Immunotherapy Program (AIP), a joint research, development and commercialization program between Wyeth and Elan that includes investigational clinical programs for bapineuzumab, the companies’ Phase 3 drug candidate. In addition, representatives from AIP and investigators will present eight posters analyzing various pharmacoeconomic and sociological aspects of Alzheimer’s disease (AD), including a podium presentation on the use of a claims database to estimate AD severity and costs by severity level. One additional poster will also be presented on the pharmacokinetics and pharmacodynamics of bapineuzumab.

Elan and Transition Therapeutics will be presenting three posters which discuss the nonclinical and clinical bioavailability of ELND005 (scyllo-inositol, formerly known as AZD-103) and an assay developed to measure its binding to beta amyloid. ELND005 is an orally-administered drug candidate in Phase 2 trials for the treatment of mild to moderate Alzheimer’s disease being jointly developed by Elan and Transition Therapeutics. Elan will also present a separate epidemiology poster on defining mild cognitive impairment. In addition, investigators at University of Toronto will also present five posters highlighting results of preclinical studies with ELND005.

About Alzheimer’s Disease

Alzheimer’s disease, a leading cause of dementia, is a progressive brain disorder that gradually destroys a person's memory and ability to learn, reason, make judgments, communicate and carry out daily activities. Alzheimer’s disease may result from the build-up of toxic beta-amyloid peptides in the brain. As Alzheimer’s disease progresses, individuals may also experience changes in personality and behavior, such as anxiety, suspiciousness or agitation, as well as delusions or hallucinations. It is currently estimated that more than 5 million Americans have Alzheimer’s disease and more than 24 million people worldwide over the age of 60 have some form of dementia (Source: Alzheimer’s Association and Alzheimer’s Disease International).
