Imaging Characteristics of Florbetapir 18F in Patients With Frontotemporal Dementia, Alzheimer's Disease and Normal Controls.

Phase 2

Completed

Brief Summary: Study 18F-AV-45-010 is designed to evaluate the cerebral uptake of florbetapir 18F as measured by PET imaging in frontotemporal disorder (FTD) in comparison to cognitively normal volunteers and subjects with Alzheimer's disease (AD).

Arm && Interventions

Group	Intervention	Description
Frontotemporal Disorder	florbetapir 18F	Subjects with frontotemporal disorder (FTD) received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F and a one-time IV bolus injection of 185 MBq of 18F-FDG.
Cognitively Normal	florbetapir 18F	Cognitively normal (CN) subjects received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F.
Alzheimer's Disease	florbetapir 18F	Subjects with Alzheimer's disease (AD) received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F.
Frontotemporal Disorder	18F-FDG	Subjects with frontotemporal disorder (FTD) received a one-time intravenous (IV) bolus injection of 300 megabecquerels (MBq) florbetapir 18F and a one-time IV bolus injection of 185 MBq of 18F-FDG.

Primary Outcome Measures

Name	Time	Method
Qualitative Amyloid Image Assessment	50-60 min after injection	Four readers blinded to all clinical information classified florbetapir Positron Emission Tomography (PET) images as either positive for amyloid or negative for amyloid. The majority read classification is presented as either positive, negative or tied.
Quantitative Amyloid Image Assessment	50-60 minutes after injection	The effect of diagnostic group on mean total cortical grey matter florbetapir binding relative to cerebellar cortex is presented as standard uptake value ratios (SUVr).
