Antibody, Aducanumab, reduces harmful brain Amyloid Plaques in Alzheimer’s patients

Biogen Alzheimer's paper Figure 1 | Amyloid plaque reduction with aducanumab: example amyloid PET images at baseline and week 54. Individuals were chosen based on visual impression and SUVR change relative to average one-year response for each treatment group (n = 40, 32, 30 and 32, respectively). Axial slice shows anatomical regions in posterior brain putatively relatedto AD pathology. SUVR, standard uptake value ratio.

The researchers furthermore demonstrated in an early stage clinical study that, after 1 year of treatment with Aducanumab, cognitive decline could be significantly slowed in antibody-treated patients as opposed to the placebo group. Although the causes of Alzheimer’s disease are still unknown, it is clear that the disease commences with progressive amyloid deposition in the brains of affected persons between 10 to 15 years before the emergence of initial clinical symptoms such as memory loss...
