NCT00657813 | Terminated Phase 1

• 1 other identifier: MNI-330-01
• Study Type: interventional
• Target: 3
• Locations: 1 country

Brief 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

EXPERIMENTAL

Drug: MNI-330 as a brain SPECT tracer of Beta-Amyloid

Interventions

MNI-330 as a brain SPECT tracer of Beta-Amyloid DRUG

Each subject will receive a bolus injection targeted to be 5 miCi and not to exceed 5.5 mCi of MNI-330. Following injection serial dynamic imaging will be obtained over 8 hrs.

• 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.
• Pregnancy
