Tau Positron Emission Tomography (PET) Longitudinal Substudy Associated With: Study of Crenezumab Versus Placebo in Preclinical Presenilin1 (PSEN1) E280A Mutation Carriers in the Treatment of Autosomal-Dominant Alzheimer's Disease
Neurodegenerative Disorder Alzheimer's Disease (AD)
Basic Details
Study Summary
This substudy will evaluate the effect of crenezumab on the longitudinal tau burden in a subgroup of preclinical Presenilin1 (PSEN1) E280A mutation carriers and non-carriers, who were enrolled in study NCT01998841 (GN28352). Participants will receive up to three intravenous (IV) injections of [^18F] Genentech Tau Probe 1 (GTP1) and will undergo a tau positron emission tomography (PET) scan after each IV injection of [18^F]GTP1. The purpose of this substudy is to increase the understanding of disease progression in the preclinical stage of familial Alzheimer's Disease (AD).
