What is being measured

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

  1. Number of Participants With Clinically Significant Cardiac Arrhythmias Using Continuous Cardiac Monitoring Over a 6-month Period With an Implanted Medtronic Reveal ICM Device

    Events defined as clinically significant for the objective include: episodes of ventricular tachycardia (VT) greater than or equal to 130 beats per minute (BPM), episodes of bradycardia indicated by a recorded heart rate less than or equal to 40 BPM, instances of asystole lasting at least three seconds, or any symptomatic event, indicated by patient use of the Reveal ICM Patient Assistant, where review of the stored ECG shows an arrhythmia considered clinically significant in the judgement of the study site cardiologist.

    Measured: 6 months of dialysis data following Reveal ICM implant

Secondary outcomes (5)
  1. Collect the Number of Device and Procedure Related Adverse Events (AEs).

    All procedure and device-related AEs will be recorded as they occur, and will be categorized according to seriousness, intensity, and relatedness to the device, device components, or implant procedure.

    Measured: 6 months of dialysis data following Reveal ICM implant

  2. Nature and Time of Health-related Events and Treatment Associated With ESRD and Other Conditions Occurring in the Implanted Patients

    Health-related events were recorded as they occurred. All health-related events were tabulated and summarized by type, time of occurrence (first 6 months and All Available Time (up to 2 years) and number of subjects affected.

    Measured: up to 6 months and through study completion

  3. Rate of Arrhythmias by Intradialytic Potassium Change and Volume Removed

    The atrial arrhythmic events, ventricular arrhythmic events, and AF burden were tabulated and reported. Atrial arrhythmic episodes were distributed temporally over the inter- and intradialytic periods using the negative binomial mixed effect regression model as described above in the primary objective analysis.

    Measured: 6 Month Follow-up

  4. Collect and Quantify the Episodes of Arrhythmias

    The atrial arrhythmic events, ventricular arrhythmic events, and AF burden will be tabulated and reported.

    Measured: 6 months of dialysis data following Reveal ICM implant

  5. Assess Whether the Morphology of ECG Recordings Captured by the Reveal ICM Device Correlate With Serum Electrolyte Levels Measured Just Before and Just After Dialysis Sessions.

    The Reveal patient Assistant will be used to trigger memory storage of 7.5 minute ECG recordings in conjunction with serum electrolyte measurements taken before and after selected dialysis sessions. Measures of ECG morphology (e.g., QT interval, QT dispersion, QRS width, T-wave amplitude) will then be extracted from the recorded ECG data. The serum electrolyte data will also be included.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing REVEAL Insertable Cardiac Monitor (ICM) in people with End Stage Renal Disease, run by Medtronic Corporate Technologies and New Ventures at 10 sites in 2 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 3 inclusion and 9 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 15 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States, India. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Feb 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Clinically Significant Cardiac Arrhythmias Using Continuous Cardiac Monitoring Over a 6-month Period With an Implanted Medtronic Reveal ICM Device (time frame: 6 months of dialysis data following Reveal ICM implant). 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 NCT01779856, which also lists 2 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 15 Feb 2021.
