About this study

The interest of the CAPRI study is to confirm the safety and the efficacy of the ENO/TEO/OTO pacing system when used under 1.5 or 3 Tesla MRI environment and in accordance with the MRI solutions guideline.

Read the detailed description

The purpose of CAPRI study is to confirm the safety and the efficacy of the CE marked MR conditional pacing system composed of the ENO, TEO or OTO pacemaker with VEGA pacing lead(s). Conditions to undergo an MRI scan are provided in the MRI solutions guideline.

The primary objective is to confirm the clinical safety of the ENO/TEO/OTO pacing system when used under 1.5 and 3 Tesla specific MRI conditions without scan exclusion zone.

The study secondary main objectives are aiming to assess the performance of the MR conditional pacing system in the right atrium and ventricle at 1 month following the MRI scan:

  • Stability of the Pacing Capture Threshold
  • Stability of the lead sensed amplitude

What is being measured

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

  1. Freedom from MRI-related complications following the MRI scan of the ENO/TEO/OTO pacing system

    An MRI-related complication is defined as a Serious Adverse Event (SAE) that led to death or to an invasive intervention or a Device Deficiency that causes the termination of any significant device function per Clinical Event Committee (CEC) adjudication.

    The primary endpoint will be assessed independently for each arm of the study (1.5 and 3 Tesla MRI scan).

    Measured: 1 month post MRI

Secondary outcomes (4)
  1. Ventricular Pacing Capture Threshold (PCT) stability in the right atrium and ventricle following the MRI scan

    Subject's ventricular pacing capture threshold will be measured in Volt (V) at 0.5ms at baseline (at the MRI visit - just before the MRI scan) and at 1 month Post-MRI visit. A success is defined as a PCT increase less than or equal to 0.5V at 0.5ms between the two visits. The secondary endpoints will be assessed independently for each arm of the study (1.5 and 3 Tesla MRI scan).

    Measured: 1 month post MRI

  2. Atrial Pacing Capture Threshold stability in the right atrium and ventricle following the MRI scan

    Subject's atrial pacing capture threshold will be measured in Volt (V) at 0.5ms at Baseline (at the MRI visit - just before the MRI scan) and at 1 month Post-MRI visit. A success is defined as a PCT increase less than or equal to 0.5V at 0.5ms between the two visits. The secondary endpoints will be assessed independently for each arm of the study (1.5 and 3 Tesla MRI scan).

    Measured: 1 month post MRI

  3. Ventricular sensed amplitude stability in the right atrium and ventricle following the MRI scan

    Subject's ventricular minimum sensed amplitude will be measured in mV at Baseline (at the MRI visit - just before the MRI scan) and at 1 month Post-MRI visit. A success is defined as 50% or less decrease between the two visits. If subject's ventricular minimum sensed amplitude is less or equal to 4mV at time of baseline, then this subject will not count for this endpoint. The secondary endpoints will be assessed independently for each arm of the study (1.5 and 3 Tesla MRI scan).

    Measured: 1 month post MRI

  4. Atrial sensed amplitude stability in the right atrium and ventricle following the MRI scan

    Subject's atrial minimum sensed amplitude will be measured in mV at baseline. A success is defined as 50% or less decrease between the two visits. If subject's atrial minimum sensed amplitude is less or equal to 1mV at time of Baseline (at the MRI visit - just before the MRI scan) and at 1 month Post-MRI visit, then this subject will not count for this endpoint.The secondary endpoints will be assessed independently for each arm of the study (1.5 and 3 Tesla MRI scan).

    Measured: 1 month post MRI

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing MRI exam in people with Bradycardia, run by MicroPort CRM at 1 site in France.

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 23 inclusion and 0 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: status not confirmed, as of the sponsor's last update on 9 Jun 2021. 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 France. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Anne RousseauPlasse (01 46 01 30 82 ext. +33, Anne.RousseauPlasse@crm.microport.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Freedom from MRI-related complications following the MRI scan of the ENO/TEO/OTO pacing system (time frame: 1 month post MRI). 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 9 Jun 2021.
