Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • -Men and non-pregnant/non-lactating women with a recent history of typical or atypical chest pain (angina) who were 18 to 80 years of age and who had been clinically indicated for SPECT evaluation for the presence of inducible ischemia were to be enrolled.

Who cannot join

  • Study candidates who have had any of the following conditions were to be excluded from the study: any clinically unstable condition or major surgery within 7 days prior to AI-700 dosing; an acute MI, cerebrovascular accident or transient ischemic attack within 30 days prior to dosing; congestive heart failure graded as New York Heart Association Grade 4 within 3 months prior to dosing; significant left main CAD; moderate to severe chronic obstructive pulmonary disease; oxygen saturation < 90% at rest; or prior CABG (unless >= 6 months prior to AI-700 dosing and patient had typical angina)
  • Candidates with significant cardiovascular or pulmonary structural and/or functional abnormality, or in whom visualization of the left ventricle was not adequate for evaluation of cardiac function during the Exclusion ECHO, were not eligible to participate in the study.
  • Patients who had a history of MI of non-CAD etiology or who exhibited new or changing ECG abnormalities at any time between Screening and AI-700 dosing were to be similarly excluded.
  • Other exclusion criteria included: participation in an investigational drug/device study within 30 days prior to dosing (90 days for UK sites), non-seasonal asthma within the past 3 years or recent seasonal asthma requiring prescription medication, organ transplant or end-stage organ failure, and active seizure disorder.
  • Candidates were to be excluded for uncontrolled atrial fibrillation, frequent premature ventricular or atrial contractions, history of prolonged QT/QTc, use of automatic implantable cardioverter/defibrillator or pacemaker, and any rhythm abnormality that had not been evaluated and treated by a specialist or for which current treatment did not ensure patient safety.
  • Candidates who had used methylated xanthines within 24 hours of dosing were also to be excluded. Patients were also to be excluded if aminophylline, theophylline, or dipyridamole were contraindicated according to each agent's product labeling.

About this study

Official title: A Phase 3, International, Multicenter, Open Label, Dual-Injection, Echocardiographic Imaging and Safety Study of AI-700 in Patients With Suspected Ischemic Heart Disease Undergoing Single-Photon Emission Computed Tomography (Real-Time Assessment of Myocardial Perfusion With Echocardiography: RAMP 1)

This study was designed to evaluate the ability of AI-700-enhanced rest-stress echocardiography to detect coronary artery disease (CAD) in patients with suspected ischemic heart disease who are indicated for single-photon emission computed tomography (SPECT) imaging.

Read the detailed description

Assessment of myocardial perfusion has been demonstrated to provide both diagnostic and prognostic value to patients with ischemic heart disease by allowing the clinician to assess the hemodynamic significance of coronary artery disease (CAD). The primary objective of the clinical development program for AI-700 is to demonstrate the safety and efficacy of AI-700 as an intravenous ultrasound contrast agent in patients with suspected myocardial perfusion defects.

The patient population is comprised of patients who are being evaluated for inducible ischemia. The primary study objective was to determine the accuracy, sensitivity, and specificity of AI-700-enhanced echocardiographic imaging for detecting CAD using coronary angiography/left ventriculography (ANGIO/LVG) or single-photon emission computed tomography (SPECT) with clinical outcome as the reference standards.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing AI-700 contrast-enhanced echocardiography in people with Coronary Artery Disease, run by Acusphere 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 6 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 14 Jul 2006. 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 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?

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?

Accuracy, sensitivity, and specificity of AI-700 ECHO in assessing CAD. 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 NCT00156793, 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 14 Jul 2006.
