Evaluation of [123I] MNI-308 and SPECT as a Marker of Beta-amyloid Protein Deposition in AD Subjects Compared to HC
Stopped early · Phase 1
Conditions studied: Alzheimer Disease
In brief
The main objectives of this proposal are as follows: To assess the dynamic uptake and washout of 123-I MNI-308, 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-308 in healthy and AD subjects to determine the metabolic fate and nature of metabolites in assessment of 123-I MNI-308 as a single photon computed tomography (SPECT) brain imaging agent Evaluate the test/retest reproducibility of 123-I MNI-308 and SPECT in AD subjects and healthy control

- Participants have a clinical diagnosis of Alzheimer's disease based on National Institute of Neurological and Communicative Disorders and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS/ADRDA) criteria.
- Mini-Mental Status Exam score < 25.
- Modified Hachinski Ischemia Scale score of ≤ 4.
- Geriatric Depression Scales (GDS) ≤ 10.
- For females, non-child bearing potential or negative urine or blood pregnancy test on day of 123-I MNI-308 injection.
- Healthy Control Subject Selection. Healthy control subjects who have no neurological disease will be recruited for this study. The following criteria will be met for inclusion of healthy control subjects in this study:
- The participant is 50 years or older.
- Written informed consent is obtained.
- Negative history of neurological or psychiatric illness based on evaluation by a research physician.

- For females, non-child bearing potential or negative urine or blood pregnancy test on day of 123-I MNI-308 injection.
You may not qualify if…
- Alzheimer's subjects will be excluded from participation for the following reasons:
- The subject has signs or symptoms of another neurodegenerative disease including Parkinson's disease, diffuse Lewy body dementia, or history of significant cerebrovascular disease.
- The subject has a clinically significant abnormal laboratory value and/or clinically significant unstable medical or psychiatric illness
- The subject has any disorder that may interfere with drug absorption distribution, metabolism, or excretion (including gastrointestinal surgery).
- The subject has evidence of clinically significant gastrointestinal, cardiovascular, hepatic, renal, hematological, neoplastic, endocrine, neurological, immunodeficiency, pulmonary, or other disorder or disease.
- Pregnancy
- Healthy control subjects will be excluded from participation for the following reasons:
- The subject has a clinically significant abnormal laboratory value and/or clinically significant unstable medical or psychiatric illness.
- The subject has any disorder that may interfere with drug absorption distribution, metabolism, or excretion (including gastrointestinal surgery).
- The subject has evidence of clinically significant gastrointestinal, cardiovascular, hepatic, renal, hematological, neoplastic, endocrine, neurological, immunodeficiency, pulmonary, or other disorder or disease.
