About this study

Official title: MODULA-Study: Modul 7 VRR: Correlation Between Ventricular Rate Regulation (VRR) and the Percentage of Biventricular Pacing as Well as Subjective Quality of Life and Level of Physical Ability in CRT Patients With Atrial Fibrillation

This study will look at the correlation between ventricular rate regulation (VRR) and the percentage of biventricular pacing as well as subjective quality of life and level of physical ability in CRT patients with atrial fibrillation.

Read the detailed description

To investigate whether VRR can increase the amount of biventricular pacing in CRT patients with conducted atrial arrhythmias. Secondarily, an investigation will be carried out to determine whether this increase in biventricular pacing results in an improvement in quality of life, as well as an improvement in the symptoms caused by the atrial arrhythmia and an improvement in the level of physical ability.

What is being measured

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

  1. Percentage of Biventricular Pacing

    Comparison of the average percentage of biventricular pacing in subjects randomised to Ventricular Rate Regulation (VRR) = ON to subjects randomized to VRR = OFF

    Measured: 6 month

Secondary outcomes (3)
  1. Correlation Between VRR and the Subjective Quality of Life

    Correlation between VRR mode and the subjective quality of life (QOL) measured by a QOL questionnaire in both randomized groups

    Measured: 6 Month

  2. Correlation Between VRR and the Symptoms Caused by Conducted Atrial Arrhythmias

    Correlation between VRR mode and conducted atrial arrhythmias (if observed) in both randomized groups

    Measured: 6 months

  3. Correlation Between VRR and Physical Ability (6 Minute Walk Test, Optional Spiroergometry)

    Correlation between VRR and physical ability in both randomized groups measured by a 6 minute walk test or an optional spiroergometry

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing CRT devices with ventricular rate regulation [VRR] (CE labeled) in people with Atrial Fibrillation, run by Boston Scientific Corporation at 1 site in Germany.

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 4 inclusion and 1 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: stopped early, as of the sponsor's last update on 24 Jun 2022. 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 Germany. 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 29 Mar 2022). 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?

Percentage of Biventricular Pacing (time frame: 6 month). 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 24 Jun 2022.
