Aducanumab is a therapeutic antibody which is directed against the lesion which characterized Alzheimer disease. During the main trial which name is EMERGE aducanumab showed a clear efficacy on the lesions as imaged by PET scans.
Unfortunately, cognitive function didn’t show a significant improvement in treated patients.
Then came a re-analysis of data.
Patients who received a higher dose of aducunumab during a longer duration of treatment did show a significant improvement of their cognitive function.
This is a very important result in the field of Alzheimer disease
