  Purpose

To determine the level of association between quantitative regional estimates of brain uptake of [18F]flutemetamol and quantitative immunohistochemical regional estimates of brain levels of amyloid estimated from post-mortem analysis of corresponding brain tissue samples.


Condition Intervention Phase
Brain Fibrillarab Levels
 Drug: [18F] Flutemetamol
 Phase 3

Study Type: Interventional
Study Design: Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: A Principal Open-Label Study to Compare the Brain Uptake of [18F]Flutemetamol With Brain Amyloid Levels Determined Post-Mortem

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Comparison of brain amyloid deposits taken from brain samples analyzed post-mortem to prior brain images made with [18F]flutemetamol. [ Time Frame: Time zero equals the date of PET imaging. After imaging, each subject will undergo follow-up until either death or study termination, whichever occurs first within a 1 year timeframe. ] [ Designated as safety issue: No ]
    To test if brain images made with [18F]flutemetamol product can safely predict which subjects have brain amyloid deposits when brain samples are analyzed post-mortem.


Secondary Outcome Measures:
  • Level of association between quantitative regional estimates of brain uptake of F18 flutemetamol from analysis of PET and quantitative histochemical regional estimates of brain levels of amyloid from post-mortem analysis of corresponding brain tissue [ Time Frame: Time zero equals the date of PET imaging. After imaging, each subject will undergo follow-up until either death or study termination, whichever occurs first within a 1 year timeframe. ] [ Designated as safety issue: No ]
    To determine the level of association between quantitative regional estimates of brain uptake of [18F]flutemetamol (from analysis of PET images) and quantitative histochemical regional estimates of brain levels of amyloid from post-mortem analysis of corresponding brain tissue samples. The quantitative estimates of brain uptake of [18F]flutemetamol SUVR will be compared to prior brain images made with [18F]flutemetamol.
