Trial summary

The study will investigate the ability of a new PET tracer, 18F-AV-1451, to detect depositions of a protein, called tau, in the brains of people with a mutation in the tau gene that causes deposition of the protein, and in people without the mutation. Read more about this study

About this study

The study will investigate the ability of a new PET tracer, 18F-AV-1451, to detect depositions of a protein, called tau, in the brains of people with a mutation in the tau gene that causes deposition of the protein, and in people without the mutation. Up to three 18F-AV-1451 scans will be performed (one per year) on control subjects without MAPT mutations, presymptomatic mutation carriers, and symptomatic mutation carriers.

Read the detailed description

Approximately 40% of cases of Frontotemporal lobar Degeneration (FTLD) are also associated with abnormal deposition of tau protein. The purpose of this study is to image MAPT mutation carriers and their non-carrier relatives in order to study the use of this tracer as a biomarker in Frontotemporal Lobar Degeneration with tau deposition (FTLD-tau).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 18F-AV-1451Drug

    Also called [18F]AV-1451

    A single injection of up to 10 millicuries of 18F-AV-1451 will be administered to subjects, followed by a 20-minute PET scan.

Study groups in NCT02676843
Study groupRoleWhat they receive
18F-AV-1451ExperimentalSubjects who are microtubule associated protein tau (MAPT) family carriers and non-carriers will receive 18F-AV-1451 by injection, and undergo a Positron Emission Tomography (PET) scan, which will then be qualitatively analyzed to examine tau deposition in the brain.
Receives: Drug: 18F-AV-1451

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. SUVR of 18F-AV-1451

    Regional tau deposition will be measured as standardized uptake value ratio (SUVR) of 18F-AV-1451. SUVR (80-100 min post-injection) for 18F-AV-1451 will be calculated two ways: 1) using cerebellar crus as a reference region, and 2) using the Parametric Estimation of Reference Signal Intensity (PERSI) method to create individual white matter reference regions. Binding in the inferior temporal lobe/cortex was used as the primary outcome.

    Measured: Baseline, 12-month follow up

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 18F-AV-1451 in people with Frontotemporal Lobar Degeneration (FTLD) and Frontotemporal Dementia (FTD), run by Columbia University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Dec 2019. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Dec 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

SUVR of 18F-AV-1451 (time frame: Baseline, 12-month follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Dec 2019.
