Prognostic Assessment of Contrast Echocardiography (PACE Study) (PACE)

April 29, 2008 updated by: Acusphere

Prognostic Assessment of Contrast Echocardiography (PACE Study): An Observational Follow-up Study of Patients With Chest Pain Evaluated With AI-700 Contrast Echocardiography

This study will demonstrate whether patients with prognostically-significant myocardial abnormalities detected with AI-700 contrast ECHO have a rate of cardiac death or MI that is higher than that of patients with normal AI-700 contrast ECHO.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This observational study will investigate the ability of AI-700 contrast ECHO to predict risk of future cardiovascular events occurring in patients who had a recent history of chest pain at the time of ECHO evaluation. Eligible patients were enrolled in either AI-700-32 or AI-700-33, which are completed Phase 3 international, multicenter, open-label, dual-injection studies of the myocardial imaging capabilities and safety of AI-700 administered intravenously in patients with chest pain. In the course of these Phase 3 studies, patients were evaluated with AI-700 contrast ECHO. In addition, eligible patients were to have had an evaluable pharmacologic stress-induced AI-700 ECHO assessment as part of AI-700-32 or AI-700-33.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

This observational study will enroll up to 773 patients who participated in either AI-700-32 or AI-700-33 and who were evaluated with AI-700 contrast ECHO at rest and at pharmacologic-induced stress. Approximately 28 international study centers will participate. At the time of AI-700 contrast ECHO (defined as the index date), the patients were to have had a recent history of chest pain and were to meet all eligibility criteria. Chest pain (angina) was defined as either:

  • typical chest pain: 1) substernal chest discomfort with a characteristic quality and duration that is 2) provoked by exertion or emotional stress and 3) relieved by rest or nitroglycerin, or
  • atypical chest pain (angina) that meets 2 of the 3 typical chest pain characteristics.

Description

Eligible patients were enrolled in either AI-700-32 or AI-700-33.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
The primary outcome variable is the time to first occurrence of the composite outcome (death or confirmed non fatal MI).
Time Frame: The time between AI 700 ECHO and outcomes data collection will be ≥12 months with an expected average follow-up period of 24 months
The time between AI 700 ECHO and outcomes data collection will be ≥12 months with an expected average follow-up period of 24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Certain secondary analyses will include revascularizations and CHF.
Time Frame: The time between AI 700 ECHO and outcomes data collection will be ≥12 months with an expected average follow-up period of 24 months
The time between AI 700 ECHO and outcomes data collection will be ≥12 months with an expected average follow-up period of 24 months

First Submitted That Met QC Criteria

First Submitted That Met QC Criteria

The date on which the study sponsor or investigator first submits a study record that is consistent with National Library of Medicine (NLM) quality control (QC) review criteria. The sponsor or investigator may need to revise and submit a study record one or more times before NLM's QC review criteria are met. It is the responsibility of the sponsor or investigator to ensure that the study record is consistent with the NLM QC review criteria.

Last Verified

Last Verified

The most recent date on which the study sponsor or investigator confirmed the information about a clinical study on ClinicalTrials.gov as accurate and current. If a study with a recruitment status of recruiting; not yet recruiting; or active, not recruiting has not been confirmed within the past 2 years, the study's recruitment status is shown as unknown.
