Outcome Measures

Primary Outcomes (1)

  • F 18 T807 Standard Uptake Value Ratios (SUVR) will be correlated with other imaging modalities (MRI, PET amyloid imaging) and cognitive performance.

    Employing statistical parametric mapping (SPM), a voxel-based analytic measure in order to quantify and co-localize the imaging patterns from the multiple imaging datasets in this study.

    5 years

Study Arms (1)

Experimental F 18 T807

Participants will undergo a PET scan using the flortaucipir imaging tracer

Drug: F 18 T807

Interventions

Participants will receive a single intravenous bolus injection of approximately 6.5-10mCi (240-370MBq) of F 18 T807. For those who cannot tolerate the full exam, participants will receive single intravenous bolus injection of approximately 6.5-10mCi (240-370MBq) of F 18 T807.

Also known as: 18F-AV-1451
Experimental F 18 T807

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

One hundred (100) participants over a period of approximately 5 years will be enrolled. Participants will undergo an F 18 T807 scan at the Center for Clinical Imaging Research (CCIR) at Washington University using an adaption of the protocol developed by Kolb and colleagues \[7\]. An MRI may be conducted if one has not been completed within the past 12 months under a related research study.

You may qualify if:

  • Male or female participants, at least 18 years of age.
  • Cognitively normal, or with mild dementia, as assessed clinically
  • Participant is able and willing to undergo testing (MRI or CT, PET, radioactive tracer injection, LP; for those unable to undergo an MRI, CT will be used to generate regions-of-interest).
  • Pre-menopausal women will undergo a urine pregnancy test within 24 hours of drug administration.

You may not qualify if:

  • Has any condition that, in the Investigator's opinion, could increase risk to the participant, limit the participant's ability to tolerate the experimental procedures, or interfere with the collection/analysis of the data (for example, participants with severe chronic back pain might not be able to lie still during the scanning procedures).
  • Is deemed likely unable to perform the imaging procedures for any reason.
  • Has a high risk for Torsades de Pointes or is taking medications known to prolong QT interval.
  • Has hypersensitivity to F 18 T807 or any of its excipients.
  • Contraindications to PET, PET-CT or MR (e.g. electronic medical devices, inability to lie still for long periods) that make it unsafe for the individual to participate.
  • Severe claustrophobia.
  • Currently pregnant or breast-feeding.
  • For those electing to undergo the optional lumbar puncture: currently on anticoagulant of any form -

These researchers may be at Washington University, at other research centers and institutions, or industry sponsors of research. We may also share the research data with large data repositories (a repository is a database of information) for broad sharing with the research community. The participant"s individual research data is placed in one of these repositories only qualified researchers, who have received prior approval from individuals that monitor the use of the data, will be able to look at this information.
