A neuroimaging technique known as ¹¹C-PiB PET* shows that a new investigational drug, bapineuzumab,** reduces amyloid-β deposits in the brain by about 25% compared with placebo in patients who have mild-to-moderate Alzheimer's disease. As such, ¹¹C-PiB PET imaging might be useful for assessing which drugs work to prevent the build up of amyloid-β deposits in the brains of people living with Alzheimer's disease. These are the conclusions of an Article published Online First and in the April issue of The Lancet Neurology.
