What is being measured

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

  1. Canadian Cardiovascular Society Angina Score

    Measured: 6 months

Secondary outcomes (9)
  1. Technical success

    Successful delivery and deployment of the Reducer to the intended site as assessed by the investigator

    Measured: 24 hours

  2. Procedural success

    Technical success and the absence of acute need for clinically-driven intervention to address an Adverse or Serious Adverse Device Effect prior to hospital discharge

    Measured: 24 hours

  3. Periprocedural Serious Adverse Event:

    A composite of death, myocardial infarction, cardiac tamponade, clinically-driven re-dilation of a failed Reducer, life-threatening arrhythmia, and respiratory failure through 30 days post-procedure in the Reducer group.

    Measured: 30 days

  4. Periprocedural Serious Adverse Event

    A composite of death, myocardial infarction, cardiac tamponade, life-threatening arrhythmia, and respiratory failure through 30 days post-procedure in the control group.

    Measured: 30 days

  5. Major Adverse Events

    A composite of cardiac death, major stroke, and myocardial infarction in the Reducer and Control groups through hospital discharge, and at six-month post-procedural evaluations.

    Measured: 6 months

  6. Canadian Cardiovascular Society Angina Score

    A decrease one or more Canadian Cardiovascular Society Angina Score grades from baseline to six-month post-procedural evaluation in Reducer and Control groups

    Measured: 6 months

  7. Dobutamine Echo Wall Motion Score Index

    Wall motion score index in both the Reducer and control groups at baseline and six-month post-procedural evaluation

    Measured: 6 months

  8. Seattle Angina Questionnaire Score

    Seattle Angina Questionnaire in the Reducer and Control groups at baseline and six-month post-procedural evaluation

    Measured: 6 months

  9. Exercise Tolerance Testing

    Exercise Tolerance Testing in the Reducer and Control groups at baseline and six-month post-procedural evaluation

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Neovasc Reducer in people with Refractory Angina, run by Shockwave Medical, Inc. at 11 sites in 6 countries.

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 8 inclusion and 19 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 25 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United Kingdom, Belgium, Canada, Denmark, Netherlands and 1 more country. 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. Some participants in this study may receive a placebo. 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?

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?

Canadian Cardiovascular Society Angina Score (time frame: 6 months). 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 NCT01205893, which also lists 3 linked publications.

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 25 Nov 2013.
