Evaluation of [123I] MNI-330 and SPECT as a Marker of Beta-amyloid Protein Deposition

Alzheimer Disease Clinical Trial

Official title: Evaluation of [123I] MNI-330 and Single Photon Emission Computed Tomography (SPECT) as a Marker of Beta-amyloid Protein Deposition in Subjects With Alzheimer Disease in Comparison to Healthy Subjects

Status Terminated

Clinical Trial Summary

The main objectives of this proposal are as follows:

To assess the dynamic uptake and washout of 123-I MNI-330, a potential imaging biomarker for β-amyloid burden in brain, using single photon emission computed tomography (SPECT) in similarly aged Alzheimer's (AD) subjects and healthy controls

To perform blood metabolite characterization of 123-I MNI-330 in healthy and AD subjects to determine the metabolic fate and nature of metabolites in assessment of 123-I MNI-330 as a single photon computed tomography (SPECT) brain imaging agent

Evaluate the test/retest reproducibility of 123-I MNI-330 and SPECT in AD subjects and healthy controls

Clinical Trial Description

The underlying goal of this study is to assess 123-I MNI-330 SPECT imaging as a tool to detect ß-amyloid deposition in the brain of AD research participants and age- and gender-matched healthy subjects. All study procedures will be conducted at the Institute for Neurodegenerative Disorders (IND) and Molecular NeuroImaging (MNI) in New Haven, CT. Approximately 10 patients with Alzheimers disease (AD) and 6 healthy controls (within +/- 2 years) will be recruited to participate in this study. Healthy controls will be examined to ensure that there is no evidence of neurodegenerative changes including cognitive decline. ;
