Arm Intervention/treatment
Experimental: Follow-up Flortaucipir PET Scan Drug: Flortaucipir F18
370 megabecquerel (MBq) IV single-dose
Other Names:
  • T807
  • 18F-AV-1451

Procedure: PET Scan
positron emission tomography (PET) scan

Primary Outcome Measures :
  1. Change in Tau Deposition Over Time by Diagnostic Group and Amyloid Status [ Time Frame: 18 months ]
    Change in flortaucipir standardized uptake value ratio (SUVr) over 18 months. For SUVr, a value of 1 signifies no flortaucipir activity above background, values greater than 1 signify increasing flortaucipir activity in the brain. A positive change in SUVr represents an increase in tau deposition in the brain. Change = 18 month SUVr - baseline SUVr obtained in Study A05.
