A PET Brain Imaging Study of mGluR5 in Subjects With Neuropsychiatric Conditions (FPEB)
Measurement of metabotropic glutamate receptor type 5 (mGluR5) binding capacity in the brain, may be a valuable tool in the early detection, understanding, or evaluation of Parkinson disease (PD), Huntington disease (HD), Fragile X syndrome (FXS), Autism Spectrum Disorder(ASD), Alzheimer's Disease(AD), and subjects with mild cognitive impairment (MCI).
The goal of this study is to assess [18F]F-PEB positron emission tomography (PET) imaging as a tool to detect mGluR5 density in the brain of PD, HD, FXS ASD, AD, and MCI research participants and similarly aged healthy subjects.
Autistic Spectrum Disorders
Fragile X Syndrome
Mild Cognitive Impairment
|Study Design:||Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
|Official Title:||Evaluation of [18F]PEB and Positron Emission Tomography (PET) as a Marker of mGluR5 in Subjects w/ Neuropsychiatric Conditions|
- Does FPEB reliably represent the known distribution of MGLUR5 in the brain? [ Time Frame: at completion of scans ] [ Designated as safety issue: Yes ]
|Study Start Date:||March 2009|
|Estimated Study Completion Date:||December 2014|
|Estimated Primary Completion Date:||December 2014 (Final data collection date for primary outcome measure)|
Experimental: Assess [18F]FPEB and PET imaging
To assess [18F] FPEB and PET imaging in subjects with neuropsychiatric conditions.
Each subject will receive a bolus injection targeted to be 5 mCi and not to exceed 5.5 mCi (not >10% of 5 mCi limit) of [18F]F-PEB
Other Name: Fluorine-18
Informed consent will be obtained for all subjects. All subjects will undergo a screening evaluation including baseline clinical laboratory testing, a baseline physical and neurological evaluation and baseline cognitive evaluations. All subjects will undergo [18F]F-PEB PET imaging. Subjects may also be asked to undergo standard brain MRI to assist in the analysis of the PET images obtained.
