Primary Outcome Measures:
  • To evaluate the bio-distribution and radiation dosimetry of [F-18]T807 in participants with low probability of Alzheimer's disease (AD) using PET/CT whole body imaging [ Time Frame: up to 15 days per patient ] [ Designated as safety issue: No ]
  • To evaluate the metabolism of [F-18]T807 in participants with low probability of AD using serial blood samples collected pre- and post-IP administration [ Time Frame: up to 15 days per patient ] [ Designated as safety issue: No ]
  • To evaluate [F-18]T807 uptake and signal/background information in brain PET/CT imaging of participants with a high probability of currently being positive for AD and age-matched participants with a low probability of currently being positive for AD [ Time Frame: upto 15 days per patient ] [ Designated as safety issue: No ]
  • To assess the safety of IV administration of [F-18]T807 [ Time Frame: up to 24 hours post [F18]T807 administration ] [ Designated as safety issue: Yes ]

    Safety will be monitored for all subjects by the:

    • Number of subjects experiencing adverse events from baseline to 24 hours post-administration.
    • Number and type of adverse events.
    • Changes in clinical laboratory assessments (CBC and clinical chemistry)from baseline to 24 hours post administration.
    • Changes in physical examination from baseline to 24 hours post administration.
    • Changes in vital sign measurements (systolic blood pressure [mmHg]; diastolic blood pressure [mmHg], pulse rate [bpm] and body temperature) from baseline prior to [F-18]T807 administration, at 60 +/- 15 minutes post administration, at the end of the final imaging session (approximately 100 minutes post administration)and at 24 hours post administration.
    • Changes in ECG measurements, from baseline prior to [F-18]T807 administration, at 60 +/- 15 minutes post administration, at the end of the final imaging session (approximately 100 minutes post administration) and at 24 hours post administration.


Secondary Outcome Measures:
  • To begin collection of baseline [F-18]T807 PET/CT imaging data [ Time Frame: up to 15 days per patient ] [ Designated as safety issue: No ]
    The secondary endpoint of this investigational study is the collection of baseline whole body PET/CT images and PET/CT images of the brain, following administration of [F-18]T807

  • To gain information to improve the study design for the conduct of future trials [ Time Frame: up to 15 days per patient ] [ Designated as safety issue: No ]
    The secondary endpoint of this investigational study is the collection of baseline whole body PET/CT images and PET/CT images of the brain, following administration of [F-18]T807


Enrollment: 11
Study Start Date: July 2012
Study Completion Date: March 2013
Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Tau diagnostic
[F18] T807
Radiation: [F18] T807
Dose for normal volunteer undergoing dosimetry evaluation will not exceed 20 mCi, dose for high probability of Alzheimer's and low probability Alzheimer's undergoing brain imaging only will not exceed 10 mCi
Other Name: Tau [F-18]T807

Detailed Description:

Siemens Molecular Imaging (SMI) is seeking to determine if [F-18]T807 might be useful as a non-invasive assessment tool in the clinical evaluation of subjects with conditions associated with tau protein aggregates, such as Alzheimer's disease. The information collected under this exploratory study will not be used for diagnostic purposes, assessments of the participant's response to therapy or for clinical management of the participants. However, this exploratory study will provide baseline information on the safety, biodistribution, and dosimetry of [F-18]T807. These data will aid in the design of future studies of [F-18]T807 in patients with Alzheimer's disease. Overall, this study will provide initial data that inform the development of [F-18]T807 as the first PET imaging agent for human tau protein related pathology.
