What is Aducanumab?
Aducanumab is a monoclonal antibody that targets amyloid beta plaques in the brain, thought to be a hallmark of Alzheimer's. It was granted accelerated approval by the FDA based on its ability to reduce these plaques. However, its effectiveness in improving clinical outcomes remains uncertain, sparking debate among experts.
Who Might Benefit?
The drug is currently considered for patients with early-stage Alzheimer's who have confirmed amyloid pathology. Its use is limited to those without contraindications like non-Alzheimer's dementia or high hemorrhagic risk. Patient selection should be thorough, involving cognitive and laboratory testing.
Risks and Monitoring
Aducanumab treatment comes with risks, including amyloid-related imaging abnormalities (ARIA), which occur in about 40% of patients. Monitoring involves regular brain MRIs to detect these abnormalities. The decision to use Aducanumab involves weighing potential benefits against these known risks.
