Brief Summary:
This study will evaluate the imaging characteristics of flortaucipir in subjects with a previous flortaucipir scan in order to assess the rate of change of tau deposition over time.

Condition or disease Intervention/treatment Phase
Alzheimer's Disease Drug: Flortaucipir F18 Drug: Florbetapir F 18 Procedure: Brain PET Scan Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 44 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: An Open Label, Multicenter Study, Evaluating the Imaging Characteristics of a Follow-up 18F-AV-1451 Scan in Subjects Who Have Had a Prior 18F-AV-1451 Scan
Actual Study Start Date : May 2014
Actual Primary Completion Date : December 2016
Actual Study Completion Date : December 2016

Arm Intervention/treatment
Experimental: Follow-up Flortaucipir PET Scan Drug: Flortaucipir F18
370 megabecquerel (MBq) IV single-dose
Other Names:
  • 18F-AV-1451
  • LY3191748
  • [F-18]T807

Drug: Florbetapir F 18
370 megabecquerel (MBq) IV single-dose
Other Names:
  • Amyvid
  • 18F-AV-45

Procedure: Brain PET Scan
positron emission tomography (PET) scan of the brain

Primary Outcome Measures :
  1. Change in Tau Deposition [ Time Frame: baseline scan and at least 6 months after baseline scan ]
    Rate of tau deposition change as measured by flortaucipir standardized uptake value ratio (SUVr). For SUVr, a value of 1 signifies no flortaucipir activity above background, values greater than 1 signify increasing flortaucipir activity in the brain.
