Phase III trials showed that bapineuzumab failed to improve cognitive and functional performances in AD patients, and was associated with a high incidence of amyloid-related imaging abnormalities (ARIA). Solanezumab's two Phase III trials in AD patients failed to meet endpoints when analyzed independently. However, analysis of pooled data from both trials showed a significant reduction in cognitive decline in mild AD patients. The improvement was associated with an increase in plasma amyloid-β (Aβ) levels and a low incidence of ARIA in solanezumab-treated patients. The marginal benefits of solanezumab are encouraging to support continued evaluation in future studies, and offer small support in favor of the ongoing viability of the 'amyloid cascade hypothesis' of AD.
