F 18 T807 Tau PET Imaging of Alzheimer's Disease
(T807IND)
What this study is about
A single-center, where both patients and doctors know the treatment given baseline controlled imaging study designed to assess whether brain tau fibril uptake of flortaucipir as measured by PET correlates with cognitive status of individuals with and without brain tau fibrils.
View original scientific description
A single-center, open-label baseline controlled imaging study designed to assess whether brain tau fibril uptake of flortaucipir as measured by PET correlates with cognitive status of individuals with and without brain tau fibrils.
Interventions
DRUG
F 18 T807
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.
Primary outcome measures
F 18 T807 Standard Uptake Value Ratios (SUVR) will be correlated with other imaging modalities (MRI, PET amyloid imaging) and cognitive performance.
Time frame: 5 years
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- 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.
Exclusion criteria
- 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 -
Where
- St Louis, Missouri

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
