Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: 18F-AV-1451 PET Imaging in Subjects With Frontotemporal Dementia
Actual Study Start Date : April 11, 2017
Actual Primary Completion Date : October 24, 2018
Actual Study Completion Date : October 24, 2018

Arm Intervention/treatment
Experimental: FTD Subjects
Subjects diagnosed by dementia specialist with a clinical Frontotemporal Dementia (FTD) syndrome and expected tau or tar DNA binding protein (TDP)-43 pathology receiving a flortaucipir PET scan
Drug: Flortaucipir F18
370 megabecquerel (MBq)(10 millicurie [mCi]) injection, single dose
Other Names:
  • 18F-AV-1451
  • [F-18]T807
  • LY3191748
  • Tauvid

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

Primary Outcome Measures :
  1. Qualitative Evaluation of Flortaucipir PET Scans [ Time Frame: baseline scan ]
    Subject scans were visually evaluated by an expert reader into three groups. Advanced Alzheimer's Disease (AD) scan pattern = In either hemisphere, increased neocortical activity in the parietal/precuneus region(s), or frontal region(s) with increased uptake in the posterolateral temporal (PLT), parietal, or occipital region(s). Moderate AD scan pattern = In either hemisphere, increased neocortical activity limited to the PLT or occipital region(s). Not AD scan pattern = No increased neocortical activity, or increased neocortical activity isolated to the mesial temporal, anterolateral temporal, and/or frontal regions.

  2. Quantitative Evaluation of Flortaucipir PET Scans [ Time Frame: baseline scan ]
    Standard Uptake Value Ratio (SUVr) using a weighted cortical average (MUBADA), and individual regions. For SUVr, a value of 1 or lower signifies no flortaucipir activity above background, values greater than 1 signify increasing flortaucipir activity in the brain.

  • Can tolerate PET scan procedures

Exclusion Criteria:

  • Have clinically significant cardiac, hepatic, renal, pulmonary, metabolic, or endocrine disturbances that pose potential safety risk
  • Have history of risk factors for Torsades de Pointes (TdP) or taking medication known to cause QT prolongation
  • Have history of drug or alcohol dependence within the last year
  • Are females of childbearing potential who are not surgically sterile, not refraining from sexual activity, or not using reliable contraception
  • Have history of relevant severe drug allergy or hypersensitivity
  • Have received an investigational medication under FDA IND protocol within 30 days of planned imaging session
  • Have received a radiopharmaceutical for imaging/therapy within 24 hours of imaging session
  • Possess PET scan evidence of amyloid deposition
  • Determined by the investigator to be unsuitable for this type of study
