Design outcomes

Primary

MeasureTime frame
Main Objective: The main study objective is to expand the investigation of diagnostic and monitoring basic markers (structural MRI, tau/abeta42 levels in the CSF, FDG PET) to advanced marker, such as molecular imaging. We will use the [11C]PK11195 (pk) that represents a validated and specific PET radioligand marker of activated microglia. Other advanced techniques will allow to collect advanced markers: Diffusion Tensor Imaging Sequences; resting functional magnetic resonance and protein p53;Secondary Objective: •To set up a large dataset of MCI patients providing clinical, imaging, and biological data (basic markers) collected at baseline in a standardized and centralized fashion, including clinical data relative to disease progression after a 12-month follow-up. •To identify the combination of basic markers with the highest accuracy for diagnosing of AD at the MCI stage. •To identify which combination of basic markers is more sensitive to disease progression. •To evaluate the incidence of Adverse events reported during all the study and until 7 days after PK administration as reported by phone. •To evaluate the vital signs at baseline (before and after radiotracer administration) and at 12-month follow-up visit;Primary end point(s): The main study objective is to expand the investigation of diagnostic and monitoring basic markers (structural MRI, tau/abeta42 levels in the CSF, FDG PET) to advanced marker, such as molecular imaging.
