About this study

Official title: A Phase 0, Open Label, Non-Randomized, Multi-Center, Exploratory and Safety Study of [F-18]T808

[F-18]T808 is being developed as a diagnostic radiopharmaceutical for PET imaging of the human brain.

Read the detailed description

Siemens Molecular Imaging (SMI) is seeking to determine if [F-18]T808 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]T808. These data will aid in the design of future studies of [F-18]T808 in patients with Alzheimer's disease. Overall, this study will provide initial data that inform the development of [F-18]T808 as the first PET imaging agent for human tau protein related pathology.

What participants receive

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

  • [F18] T808Radiation

    Also called Tau [F-18]T808

    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

What is being measured

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

  1. To monitor and assess the safety of IV administration of [F-18]T808

    To monitor and assess the safety of IV administration of [F-18]T808 To evaluate the bio-distribution and radiation dosimetry of [F-18]T808 in participants with low probability of Alzheimer"s disease (AD) using PET/CT whole body imaging To evaluate the metabolism of [F-18]T808 in participants with low probability of AD using serial blood samples collected pre- and post-IP administration To evaluate [F-18]T808 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

    Measured: up to15 days per patient.

Secondary outcomes (1)
  1. To begin collection of baseline [F-18]T808 PET/CT imaging data

    To begin collection of baseline [F-18]T808 PET/CT imaging data To gain information to improve the study design for the conduct of future trials

    Measured: up to14 days per patient

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing [F18] T808 in people with Alzheimers Disease, run by Avid Radiopharmaceuticals at 2 sites 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?

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: stopped early, as of the sponsor's last update on 19 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

Are results available for this study?

The study was stopped early (reason given: Study was terminated in anticipation of transfer of ownership to Avid Radiopharmaceuticals.). Results are not available in the source record.

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?

To monitor and assess the safety of IV administration of [F-18]T808 (time frame: up to15 days per patient.). 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 19 Jul 2013.
