Clinical Trial Summary

A regional, single-center, prospective, observational academic cohort will follow subjects who previously participated in the INSIGHT study and who agree an extension of their follow-up in the INSIGHT-2 research for additional 5-6 years. An annual multimodal evaluation (cognitive, oculomotor, biological and neuroimaging) will be proposed in order to describe the natural history of preclinical Alzheimer's disease (AD). The primary endpoint is the conversion to the symptomatic stage in subjects at risk, identified by positive amyloid staining (A+) on florbetapir positron emission tomography (PET) imaging. The size of the cohort is estimated to around 240 participants (61 A+ subjects) among the 318 participants included in the main cohort (88 A+ subjects). The follow-up in the INSIGHT-2 cohort will be lightened compared to that of the main cohort with an annual frequency of visits rather than a six-monthly one.
