New Alzheimer vaccine to be tested in Europe

Excerpt: The AD02 vaccine, developed with British drugmaker GlaxoSmithKline, was already tested for safety and tolerability over the past year.

The clinical trials will now test its efficacy, with results expected as early as 2012, the company said.

ADO2 is meant to prevent the building up of beta-amyloid plaques in the brain, which cause the degradation of nerve cells and are believed to play a crucial role in causing Alzheimer's disease.

The vaccine works by causing the body to attack these plaques by producing more antibodies, Till Jelitto, a spokesman for Affiris, told AFP.

More specifically, these antibodies are meant to attack only the part of the beta-amyloid protein that causes the plaques, he added.

This would reduce the risk for patients, as the protein as a whole already exists in healthy individuals.

The current vaccine is therapeutic, meaning it is aimed at treating patients already affected by the disease. But if results are positive, the technology could also be used to manufacture a prophylactic, or preventative, vaccine, Jelitto said.
