Trial summary
This project will collect quantitative pilot data that will allow the characterization of uptake and binding of 18F-AV-1451 (also known as F 18 T807), a novel tau imaging compound, in individuals with Progressive Posterior Cortical Dysfunction (PPCD) and logopenic variant primary progressive aphasia (lvPPA).

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 45 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: Collaborating physicians and the Knight ADRC Clinical Core will refer participants to the Knight ADRC Research Imaging (KARI) Program for MR and PET imaging to evaluate tau distribution in the brains of cognitively normal and cognitively impaired individuals, with the primary goal of developing this highly promising tau imaging technique as an antecedent biomarker of cognitive decline. We propose to recruit groups of patients with PPCD and lvPPA from the same clinical environment.
Who may be able to join
- Male or female participants, at least 45 years of age.
- Clinical diagnosis of PPCD.
- 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 have a negative urine pregnancy test within 24 hours of T807 drug administration.
Who cannot join
- 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: on anticoagulant of any form prior to lumbar puncture.

About this study
Official title: F 18 T807 Tau PET Imaging of Progressive Posterior Cortical Dysfunction Due to Alzheimer Disease
This project will collect quantitative pilot data that will allow the characterization of uptake and binding of 18F-AV-1451 (also known as F 18 T807), a novel tau imaging compound, in individuals with Progressive Posterior Cortical Dysfunction (PPCD) and logopenic variant primary progressive aphasia (lvPPA). The primary goal is to develop tau imaging technique as an antecedent biomarker of cognitive decline. The investigators propose to obtain preliminary data that will support the possibility of detecting cognitive decline in its earliest stages, before the occurrence of dementia.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
F 18 T807Drug
Also called 18F-AV-1451
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
F 18 T807 Standard Uptake Value Ratios (SUVR) will be correlated with other imaging modalities (MRI, PET amyloid imaging) and cognitive performance.
Measured: 5 years

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02414282, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2021.
