Bridging Study of C11 PiB and F18 Flutemetamol Brain PET
In Brief
A Phase 2 clinical trial evaluating C11 PiB and F18 Flutametamol for Alzheimer's Disease. Completed, enrolled 89 participants across 1 site.
Detailed Summary
The intent of this research protocol is to test the equivalency of two amyloid imaging drugs (C11 Pittsburgh Compound B and F18 Flutemetamol). The investigators hypothesize that there will be no significant difference in the distribution of the agents to areas of amyloid deposition in the brain or to other normal brain structures. Recent data have shown similarity in the distribution of the drugs in subjects with Alzheimer's disease (AD) or mild cognitive impairment (MCI). No comparison data of the two PET drugs in normal subjects has been published. It is important to understand differences in the images and biodistribution from the two drugs in normal subjects as nonspecific accumulation of the drugs in brain structures such as white matter appear to differ slightly and could affect image performance.
