What is being measured

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

  1. The Maximum Diagnostic Mass by assessing the visual read out of amyloid status according to and quantification of an [18F]AZD4694 PET image in a high mass experiment compared to the image in a low mass experiment in the same subject.

    Measuring the maximum chemical mass not causing any significant alteration of the amyloid status (unit = micrograms)

    Measured: Visit 3

  2. The Maximum Diagnostic Mass by assessing the visual read out of amyloid status according to and quantification of an [18F]AZD4694 PET image in a high mass experiment compared to the image in a low mass experiment in the same subject.

    Measuring the maximum chemical mass not causing any significant alteration of the amyloid status (unit = micrograms)

    Measured: Visit 4

Secondary outcomes (3)
  1. Number of Adverse Events as a measure of Safety and tolerability of [18F]AZD4694

    Measured: Range of Visits 3-5

  2. Correlation between early uptake of [18F]AZD4694 images and cerebral blood flow images as measured by Arterial Spin Labeling Magnetic resonance imaging

    Measured: Range of Screening Visit to Visit 4

  3. Correlation between estimates of β-amyloid load in brain obtained using [18F]AZD4694 Position Emission Tomography imaging and concentrations of β-amyloid in Cerebrospinal fluid

    Measured: Range of Screening Visit to Visit 4

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [18Fluor]AZD4694 in people with Maximum Diagnostic Mass of [18Fluor]AZD4694, run by AstraZeneca at 2 sites in Sweden.

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 5 inclusion and 15 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 10 Dec 2012. 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 Sweden. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 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?

The Maximum Diagnostic Mass by assessing the visual read out of amyloid status according to and quantification of an [18F]AZD4694 PET image in a high mass experiment compared to the image in a low mass experiment in the same subject. (time frame: Visit 3). The study lists 2 primary outcomes in all. 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 10 Dec 2012.
