About this study

Official title: A Prospective Multicenter Phase III Clinical Evaluation of the Safety and Efficacy of Lumason™/SonoVue® in Subjects Undergoing Pharmacologic Stress Echocardiography With Dobutamine for the Diagnosis of Coronary Artery Disease

Read the detailed description

The study was designed to assess the safety and efficacy of Lumason at improving the visualization of the LV EBD during pharmacologic stress echocardiography examinations and for detection or exclusion of the coronary artery disease (CAD). The study population consisted of adult subjects referred for pharmacological stress echocardiography and with suboptimal image quality during unenhanced ultrasound imaging at rest who had known or suspected CAD. Subjects enrolled in the study represented subjects who could benefit most from CEUS stress echocardiography.

Conditions: Coronary Artery Disease
Being tested: Lumason
Keywords: Lumason, Dobutamine stress echo, stress echo, coronary artery disease
Medical subject headings: Coronary Artery Disease

What participants receive

What is being measured

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

Sensitivity and Specificity of Lumason Enhanced Dobutamine Stress Echo (DSE) for Detection or Exclusion of Coronary Artery Disease (CAD)
The diagnostic performance of the echocardiographic images was compared to the truth standard to determine sensitivity and specificity. A diagnosis of CAD was determined for both the echo images and truth standard (positive diagnosis for CAD is defined as >/= 50% stenosis of any vessel on coronary angiography or if no coronary angiography was performed the occurence of a cardiac event based on clinical information for up to 6 months post dose; otherwise the diagnosis was negative).
Results for sensitivity and specificity are reflected based on difference between contrast enhanced stress echo and unenhanced stress echo. Results for analysis of data based on majority assessment from the three off-site blinded readers are presented.
Sensitivity and specificity are the percentages of correctly diagnosed subjects by stress echo over the total positive and negative subjects according to the truth standard respectively.
Measured: Participants were followed until they had coronary angiography or up to 6 months post dose to collect clinical information on cardiac events if no coronary angiography were performed
Reader-Specific Percentages of Participants Identified as Having a Critical Shift From Suboptimal to Optimal Echocardiographic Images
The percentage of subjects with suboptimal images (defined as >= 2 adjacent segments with inadequate LV EBD in any of the 3 apical views) at unenhanced stress echo converted to adequate (reduction of suboptimal segments in any of the 3 apical views) at contrast-enhanced stress echo
Measured: Participants were followed until they had coronary angiography or up to 6 months post dose to collect clinical information on cardiac events if no coronary angiography was performed

Secondary outcomes (2)

Change in Total LV EBD
Measured as the change in the total LV EBD score based on the 17 segments, from peak stress unenhanced vs. peak stress contrast-enhanced. Total LV EBD score ranges from 0 to 34 and higher score is better outcome.
Measured: Participants were followed until they had coronary angiography or up to 6 months post dose to collect clinical information on cardiac events if no coronary angiography was performed
Number of Participants With Adverse Events
To obtain safety data in subjects administered Lumason during echocardiography
Measured: 72 hours post dose

Who may be eligible to take part?

The sponsor lists 4 inclusion and 30 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 7 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, Belgium, United Kingdom, Canada. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 5 Aug 2020). 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?

What does the primary outcome measure?

Sensitivity and Specificity of Lumason Enhanced Dobutamine Stress Echo (DSE) for Detection or Exclusion of Coronary Artery Disease (CAD) (time frame: Participants were followed until they had coronary angiography or up to 6 months post dose to collect clinical information on cardiac events if no coronary angiography were performed). 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?

On the ClinicalTrials.gov record for NCT02552238.

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 7 Jul 2021.
