What is being measured

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

  1. Finding the Optimal Dose of Optison From 3 Different Dose Levels; 0.15mL, 0.5mL, and 1.5mL.

    Assessing the presence of disease of the carotid arteries when comparing pre-contrast to post-contrast ultrasound (U/S) by dose group. Using the optimal dose from 3 different dose levels - 0.15 mL, 0.5 mL and 1.5 mL of Optison.

    Measured: Up to 10 minutes post contrast administration.

Secondary outcomes (1)
  1. Detecting the Presence of Greater Than or Equal to 50% Stenosis and Greater Than or Equal to 75% Stenosis in the Carotid Arteries When Comparing Pre-contrast to Post-contrast Ultrasound by Dose Group.

    Detecting the presence of greater than or equal to 50% stenosis and greater than or equal to 75% stenosis in the carotid arteries when comparing pre contrast to post-contrast U/S by dose group.Using the 3 different dose levels of 0.15 mL, 0.5 mL and 1.5 mL of Optison.

    Measured: Up to 10 minutes post contrast administration.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Optison in people with Carotid Artery Disease, run by GE Healthcare 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 4 inclusion and 4 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: stopped early, as of the sponsor's last update on 2 May 2014. 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 16 Apr 2014). 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?

Finding the Optimal Dose of Optison From 3 Different Dose Levels; 0.15mL, 0.5mL, and 1.5mL. (time frame: Up to 10 minutes post contrast administration.). 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 2 May 2014; AzTrials last refreshed its copy on 1 Nov 2026.
