DIAN-TU Amyloid Removal Trial (ART) in Dominantly Inherited Alzheimer's Disease

Summary

This is an open label study to treat dominantly inherited Alzheimer's disease (DIAD) mutation carrier participants from the DIAN-TU-001 gantenerumab Open Label Extension (OLE) period with lecanemab to determine the effects of amyloid removal on age of onset and clinical progression compared to external controls, if amyloid plaque as measured by amyloid PET can be fully removed in DIAD, and the effects of amyloid removal on biomarkers of disease progression.
