About this study

Official title: Evaluation of [123I] AV39 and SPECT as a Marker of Beta-Amyloid Protein Deposition in Subjects With Alzheimer Disease in Comparison to Healthy Subjects

The underlying goal of this study is to assess 123-I AV39 SPECT imaging as a tool to detect ß-amyloid deposition in the brain of AD research participants and age- and gender-matched healthy subjects.

Read the detailed description

Approximately 20 patients with Alzheimer's disease (AD) and 10 healthy controls will be recruited to participate in this study. Healthy controls will be examined to ensure that there is no evidence of neurodegenerative changes including cognitive decline.

All subjects will undergo written informed consent and a screening evaluation including baseline clinical laboratory testing, a baseline physical and neurological evaluation and baseline cognitive evaluations.

Subjects will be asked to undergo a bolus injection of 123-I AV39. Subjects will undergo serial SPECT imaging scans and serial venous plasma sampling for measurement of 123-I AV39 in plasma (both protein bound and free) over a period of up to 6 hours.

Subjects may be asked to undergo a second imaging visit between 2 and 6 weeks following the initial imaging visit following similar procedures to the initial imaging visit to evaluate the reproducibility of the imaging measure using this procedure. The imaging analyses will be performed by an image-processing specialist who will remain masked to the procedures employed with each imaging acquisition.

The primary imaging outcome measure will be the brain regional distribution volumes expressed as a brain tissue to plasma ratio of the radioligand, 123-I AV39. Time to the peak uptake and amplitude of the peak uptake will be evaluated for all brain regions and the results for the AD patients and controls will be compared.

For those subjects undergoing repeat imaging visits, the data from the initial scan will be compared to the second scan to determine which offers the reproducibility of the imaging outcome measure.

What is being measured

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

  1. Assess the dynamic uptake and washout of 123-I AV39

Secondary outcomes (2)
  1. Blood metabolite characterization of 123-I AV39 in healthy and AD subjects to determine the metabolic fate and nature of metabolites

  2. Evaluate the test/retest reproducibility of 123-I AV39 and SPECT in AD subjects and healthy controls

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing [123I] AV 39 in people with Alzheimers Disease, run by Molecular NeuroImaging 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 7 inclusion and 5 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 24 Apr 2008. 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 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?

Assess the dynamic uptake and washout of 123-I AV39. 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 24 Apr 2008.
