About this study

Official title: DUTCH Weight Control in Atrial Fibrillation Study, a Multi-center, Double-blind, Randomized, Parallel Group, Placebo-controlled Trial

Quantify the effect of an innovative weight loss management on rhythm control.

Read the detailed description

Rationale: Weight reduction promotes reversed atrial remodeling in obese AF patients.

Objective: Quantify the effect of an innovative weight loss management on rhythm control.

Study design: Multi-center, double-blind, randomized, parallel group, placebo-controlled trial of semaglutide 2.4 mg versus placebo.

Study population: Adults with obesity and new onset persistent AF scheduled for electrical cardioversion.

Intervention: semaglutide 2.4 mg subcutaneous (s.c.) once weekly (index) compared to placebo (control), at the background of standard obesity treatment (combined lifestyle intervention) and cardiology follow-up management in both arms.

Main study parameters/endpoints: The primary efficacy clinical endpoint of the trial is assessed at 12 months by a 7 point scale. Only the worst clinical outcome will be retained as the primary efficacy outcome. The 7 mutually exclusive outcomes hierarchically ranked from worst to best are:

  • Arrhythmic death while using anti-arrhythmic drugs (Vaughn-Williams class I or III)*
  • AF despite pulmonary vein isolation
  • AF despite current use of anti-arrhythmic drugs (Vaughn-Williams class I or III)
  • AF without a pulmonary vein isolation and without the current use of anti-arrhythmic drugs (Vaughn-Williams class I or III)
  • Sinus rhythm on the 12-lead ECG with the use of a pulmonary vein isolation
  • Sinus rhythm on the 12-lead ECG with current use of anti-arrhythmic drugs (Vaughn-Williams class I or III)
  • Sinus rhythm on the 12-lead ECG without the current use of anti-arrhythmic drugs (Vaughn-Williams class I or III) and without a pulmonary vein isolation
  • When LTFU or death other than anti-arrhythmic death, last known rhythm will be used.

What is being measured

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

  1. The primary efficacy clinical endpoint of the trial is assessed at 12 months by a 7 point scale. Only the worst clinical outcome will be retained as the primary efficacy outcome

    The 7 mutually exclusive outcomes hierarchically ranked from worst to best are:

    • Arrhythmic death while using anti-arrhythmic drugs (Vaughn-Williams class I or III)*
    • AF despite pulmonary vein isolation
    • AF despite current use of anti-arrhythmic drugs (Vaughn-Williams class I or III)
    • AF without a pulmonary vein isolation and without the current use of anti-arrhythmic drugs (Vaughn-Williams class I or III)
    • Sinus rhythm on the 12-lead ECG with the use of a pulmonary vein isolation
    • Sinus rhythm on the 12-lead ECG with current use of anti-arrhythmic drugs (Vaughn-Williams class I or III)
    • Sinus rhythm on the 12-lead ECG without the current use of anti-arrhythmic drugs (Vaughn-Williams class I or III) and without a pulmonary vein isolation
    • When LTFU or death other than anti-arrhythmic death, last known rhythm will be used.

    Measured: At 1 year follow-up

Secondary outcomes (11)
  1. Change in AF related symptoms measured by the modified EHRA classification between the index visit and at 12 months after the index visit.

    EHRA: European Heart Rythm Association

    1= no symptoms 2a= mild symptoms; Normal dialy activity not affected, symptoms not troublesome to patient 2b= moderate symptoms; Normal daily activity not affected but patient troubled by symptoms 3= severe symptoms; Normal daily activity affected 4= disabling symptoms; Normal daily activity discontinued

    Measured: week 0 and 52

  2. Change in quality of life measured by the EQ-5D-5L between the index visit and at 12 months after the index visit.

    Descriptive system for health-related quality of life states in adults, consisting of five dimensions (Mobility, Self-care, Usual activities, Pain \& discomfort, Anxiety \& depression), each of which has five severity levels that are described by statements appropriate to that dimension.

    LEVEL 1: indicating no problem LEVEL 2: indicating slight problems LEVEL 3: indicating moderate problems LEVEL 4: indicating severe problems LEVEL 5: indicating unable to/extreme problems

    Measured: week 0 and 52

  3. Number of hospitalizations because of an AF recurrence.

    Measured: week 0-52

  4. Number of unscheduled hospital visits because of adverse events of AAD.

    Measured: week 0-52

  5. Number of scheduled electrical cardioversions.

    Measured: week 0-52

  6. Number of unscheduled electrical cardioversions.

    Measured: week 0-52

  7. Number of intravenous chemical cardioversions (using Vaughan-Williams class I drugs).

    Measured: week 0-52

  8. Total number of unscheduled cardioverions.

    Measured: week 0-52

  9. Change in waist circumference, measured in cm

    Measured: week 0 and 52

  10. Change in weight, measured in % and kg

    Measured: week 0 and 52

  11. Change in BMI, measured in kg/m2

    Measured: week 0 and 52

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Semaglutide 3.2 MG/ML in people with Atrial Fibrillation and Obesity, run by Rijnstate Hospital at 20 sites in Netherlands.

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 7 inclusion and 16 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: under way, not looking for participants, as of the sponsor's last update on 1 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in Netherlands. 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 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?

This study is still under way. Results are not available in the source record yet.

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?

The primary efficacy clinical endpoint of the trial is assessed at 12 months by a 7 point scale. Only the worst clinical outcome will be retained as the primary efficacy outcome (time frame: At 1 year follow-up). 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 1 Oct 2026.
