About this study

The purpose of this study is to assess the image quality of Ablavar-enhanced MR angiography of the central veins of the chest, and to determine whether dose reduction can be performed while maintaining image quality. This will be a prospective randomized study, in which healthy volunteers will be recruited to undergo a central veins magnetic resonance angiogram (MRA). They will receive either the FDA-approved dose or a lower dose of Ablavar. Quantitative and qualitative analysis will be performed on the images.

What is being measured

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

  1. Imaging Quality Score

    Two radiologists assessed imaging quality of each central venous segment for each patient, in order to compare imaging quality between each of the three doses administered. The visualization score for each venous segments was as follows:

    1. poor / nondiagnostic
    2. adequate
    3. good
    4. excellent

    Measured: 14 weeks

Secondary outcomes (1)
  1. Quantitative Analysis Noise Ratios

    Signal-to-noise and contrast-to-noise ratios were calculated for each central venous segment, to determine the magnitude of difference in each of the three administered doses. The ratio's were calculated as follows:

    Signal-to-noise ratio: signal intensity of vessel segment / standard deviation of signal intensity of the background.

    Contrast-to-noise ratio = (signal intensity of vessel segment minus signal intensity of adjacent muscle) / standard deviation of signal intensity of the background.

    Measured: 14 weeks

Questions about this trial

What is this clinical trial studying?

A study testing gadofosveset in people with Healthy, run by Duke 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 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 10 Dec 2013. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Dec 2013). 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?

Imaging Quality Score (time frame: 14 weeks). 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 NCT01431300, 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 10 Dec 2013.
