Conditions

Dominantly Inherited Alzheimer Disease (DIAD)

Brief summary

The primary and secondary endpoints measures will be collected through the DIAN Obs protocol. The primary endpoint for the interim analysis is the change from ART baseline to year 1 or year 2 in amyloid Pittsburgh compound B (PiB) PET standardized uptake value ratio (SUVR). The primary endpoint for the final analysis is the time to recurrent progression of Clinical Dementia Rating – Sum of Boxes (CDR-SB).

Detailed description

The secondary endpoint analysis will be the change from ART baseline to year 5 in the following assessments: imaging (amyloid PET, tau PET), clinical (Functional Assessment Scale), plasma and CSF biomarkers of disease progression including Aβ42/40, tau species (%phosphorylated tau217, 205, 231), total tau, and microtubule-binding region (MTBR) species, e.g. MTBR-243. These assessments are collected at the initial DIAN Obs Visit (which coincides with DIAN‐TU‐003 V2) and...Truncated due to limit
