While the paper issue of the publication will be available in a future issue of Neurobiology of Aging, an electronic version of the article entitled "Targeting soluble Aβ peptide with Tramiprosate for the treatment of brain amyloidosis" is already accessible online, and can be found at http://www.sciencedirect.com by searching for "tramiprosate".
Findings about tramiprosate (Alzhemed) include:
The presence of amyloid in the brain is one of the major histopathological characteristics of AD. The amyloid cascade hypothesis proposes that certain forms of Aβ peptide are toxic and causally related to the severity of AD. The Aβ-peptide is one of the most promising targets for the development of AD therapies.
"This scientific paper highlights the potential benefits of Alzhemed™," said Dr. Andreas Orfanos, Neurochem's Executive Vice President, Strategic Planning and Scientific Affairs. "These preclinical results indicate that Alzhemed
About tramiprosate (Alzhemed™)
Tramiprosate (Alzhemed™) is a small, orally-administered molecule known as an amyloid β antagonist, designed to cross the blood-brain-barrier, bind to soluble Aβ peptide and interfere with the amyloid cascade, thereby leading to the prevention or inhibition of amyloid deposition and the toxic effects of Aβ peptide in the brain.
About the Phase III Clinical Trials for tramiprosate (Alzhemed™)
Neurochem is currently conducting a multi-center, randomized, double-blind, placebo-controlled and parallel-designed, 18-month Phase III clinical trial in 1,052 mild-to-moderate AD patients which is being carried out at close to 70 clinical sites across the United States and Canada. To date, 600 patients have already completed 12 months on study medication and the trial is scheduled to be completed by January 2007. All patients who complete the North American Phase III clinical trial will be offered the opportunity to receive tramiprosate (Alzhemed™) in an open-label extension study.
Neurochem is also actively advancing an 18-month Phase III clinical trial for tramiprosate (Alzhemed™) in Europe, which was initiated in September 2005. The ongoing European Phase III clinical trial, an international, multi-center, randomized, double-blind, placebo-controlled and parallel-designed study, is progressing on schedule and will investigate the safety, efficacy and disease-modifying potential of tramiprosate (Alzhemed™). Some 930 mild-to-moderate AD patients are expected to take part and enrollment is expected to be completed in the fall of 2006.
About Alzheimer's disease
Alzheimer's disease (AD) is a progressive form of dementia associated with specific brain pathologies. It impairs a person's cognitive and motor functions, their activities of daily living, alters the behaviour and gradually destroys the brain.
AD is the most common cause of dementia in our aging population. Almost 5 million individuals in the United States alone currently suffer from the condition. The U.S. Alzheimer's Association estimates that by 2025, over 22 million people worldwide will be afflicted.
According to a report commissioned by the U.S. Alzheimer's Association, AD costs American businesses approximately US$61 billion a year. That price tag includes US$24.6 billion for direct health care of Alzheimer's patients and US$36.5 billion to cover costs related to caregivers of AD patients, including lost productivity, absenteeism and worker replacement.
Neurochem is focused on the development and commercialization of innovative therapeutics to address critical unmet medical needs. Eprodisate (Fibrillex™) is designated as an orphan drug, is a Fast Track product candidate and is also part of the U.S. Food and Drug Administration (FDA) Continuous Marketing Application Pilot 1 and Pilot 2 programs. In April 2006, the FDA filed and granted the eprodisate (Fibrillex™) new drug application for priority review. Tramiprosate (Alzhemed™), for the treatment of Alzheimer's disease, is currently in Phase III clinical trials in both North America and Europe and tramiprosate (Cerebril™), for the prevention of Hemorrhagic Stroke caused by Cerebral Amyloid Angiopathy, has completed a Phase IIa clinical trial.

This news release contains forward-looking statements regarding tramiprosate (Alzhemed™) as well as regarding continuing and further development efforts. These statements are based on the current analysis and expectations of management. Drug development necessarily involves numerous risks and uncertainties, which could cause actual results to differ materially from this current analysis and these expectations. Analysis regarding the results of clinical trials may not provide definitive results regarding safety, tolerability or therapeutic benefits. Even if all the endpoints sought in the clinical trials were met (which is not certain), there is no certainty that regulators would ultimately approve tramiprosate (Alzhemed™) for sale to the public. Risks and uncertainties may include: failure to demonstrate the safety, tolerability and efficacy of our product, the expense and uncertainty of obtaining regulatory approval, including from the FDA, and the possibility of having to conduct additional clinical trials. Further, even if regulatory approval is obtained, therapeutic products are generally subject to: stringent on-going governmental regulation, challenges in gaining market acceptance, and competition. Neurochem does not undertake any obligation to publicly update its forward-looking statements, whether as a result of new information, future events, or otherwise. Please see the Annual Information Form for further risk factors that might affect the Company and its business.
