Amyloid is an abnormal chemical found in the brain of patients with Alzheimer's Disease (AD). The study drug helps produce pictures of amyloid in the brain. The purpose of this study is to determine how well the study drug performs in young healthy subjects.

Condition Intervention Phase
Drug: [18F] Flutemetamol
Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: A Single-arm, Open-label, Multi-center Study to Determine the Specificity of Flutemetamol (18F) Injection for Excluding the Presence of Brain Amyloid in Healthy Young Adult Subjects Aged 18 to 40

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Number of Brain Scans in Healthy Young Adults Subjects Which do Not Show Amyloid [ Time Frame: PET scans performed on patients 90 minutes post Flutemetmol Administration ]

    The visual assessment of Flutemetamol PET image was performed by independent readers trained in the evaluation of PET brain amyloid imaging.

    The measure would consisted of the number of brain scans with amyloid (abnormal reading) or without amyloid (normal reading).

Secondary Outcome Measures:
  • Measurement of Amyloid Content in Different Parts of the Brain [ Time Frame: PET scans performed on patients 90 minutes post Flutemetmol Administration ]

    Is the computerized measurement of amyloid content in different parts of the brain.

    The Standard Uptake Value Ratio (SUVR) is defined as an average of frontal, anterior cingulate, pariteal, lateral-temporal and posterior cingulate / precuneous uptake following administration of Flutemetamol F18 Injection.

    The Standard Uptake Value Ratio is calculated for two regions of the brain, the Cerebullum and the Pons regions.

    The Standard Uptake Value Ratio is calculated for two regions of the brain, the Cerebullum and the Pons regions. Both regions of the brain will provide the SUVR measurements.
