What is being measured

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

  1. Binary in-stent restenosis rate of the Express™ Renal Stent at nine (9) months, defined by quantitative angiography.

    Measured: 9 months

Secondary outcomes (8)
  1. Procedural Success - <30% residual diameter stenosis as visually assessed by the investigator without the occurrence of in-hospital MAE.

    Measured: Post stent deployment

  2. Target Lesion Revascularization(TLR)*- Clinically driven reintervention of the target lesion through 9-months.

    Measured: 9 months

  3. Target Vessel Revascularization(TVR)* - Clinically driven reintervention of the target vessel through 9-months.

    Measured: 9 Months

  4. Change (improvement) in renal function from pre-procedure to post-procedure, 1-month and 9-month followups

    Measured: 9 months

  5. Change in Renal to Aortic Ratio, Resistive Index, and Peak Systolic Velocity using Ultrasound Core Lab values from pre-procedure to postprocedure and 9-months post-procedure.

    Measured: 9 Months

  6. Change (improvement) in hypertension control from pre-procedure to post-procedure, 30-day and 9-month followups

    Measured: 9 Months

  7. Major Adverse Events (MAEs): device- or index procedure related death ,TLR, Significant Embolic Event through 9 months post-procedure

    Measured: 9 Months

  8. Technical success as visually assessed by the investigator.

    Measured: Immediately after stent deployment

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Express™ Renal Premounted Stent System in people with Atherosclerotic Lesions in the Aortorenal Ostium, run by Boston Scientific Corporation at 14 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 8 inclusion and 23 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 21 Nov 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Binary in-stent restenosis rate of the Express™ Renal Stent at nine (9) months, defined by quantitative angiography. (time frame: 9 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 NCT00597142, 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 21 Nov 2014.
