July 13, 2009 - Potential to visualize beta-Amyloid plaques in Patients with Alzheimer’s disease demonstrated / Florbetaben may innovate the diagnostic capabilities – Bayer Schering Pharma AG, Germany, has presented positive data on a global Phase II study with the novel positron emission tomography (PET) tracer florbetaben (BAY 94-9172) at the International Conference on Alzheimer's Disease (ICAD) in Vienna, Austria. This study showed that patients with a clinical diagnosis of Alzheimer´s disease could be differentiated from age-matched healthy volunteers (HVs) on the basis of florbetaben uptake pattern in the brain.Until now, the clinical diagnosis of Alzheimer´s disease (AD) with current methods such as cognitive tests is still limited. Currently, a definite diagnosis of Alzheimer´s disease is only possible post mortem. The results of this study showed PET images with a high specificity of over 90 percent: More than 90 percent of the HVs had a negative florbetaben scan (i.e. no tracer uptake) in the relevant brain regions. The results also show a sensitivity of approximately 80 percent indicated by the clinical diagnosis, meaning that about 80 percent of the clinically suspected Alzheimer patients had positive florbetaben scans indicating the presence of beta-Amyloid plaques. This is in line with the results of studies comparing the clinical diagnosis with the definite post mortem histopathological diagnosis...
