What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PB127 for injectable suspensionDrug

    Also called CARDIOsphere®

    0.175 mg/kg diluted in 150 mL Dextrose in Water 5% in glass bottles to be infused at 250 mL/hour until stead state achieve, 150 mL/hour during rest image acquisition, and 100-150 mL/hr during stress image acquistion. Single IV infusion, not to exceed 60 minutes.

What is being measured

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

  1. To demonstrate the non-inferiority of the diagnostic performance of PB127 MCE versus stress SPECT in the detection and/or exclusion of significant obstructive CAD as defined by QCA or qualifying clinical outcome.

    Measured: 90 days

Secondary outcomes (2)
  1. To assess the concordance of PB127 MCE with stress SPECT in differentiating between reversible vs. fixed defects in patients with significant obstructive CAD

    Measured: 28 days

  2. To compare the diagnostic performance of PB127 MCE with stress SPECT in identifying the location of stenosis as identified by coronary angiography.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing PB127 for injectable suspension in people with Coronary Artery Disease, run by Point Biomedical at 15 sites 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 21 inclusion and 31 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 3 Jul 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites 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?

To demonstrate the non-inferiority of the diagnostic performance of PB127 MCE versus stress SPECT in the detection and/or exclusion of significant obstructive CAD as defined by QCA or qualifying clinical outcome. (time frame: 90 days). 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 3 Jul 2008.
