Trial summary

Our hypothesis is that episodic amiodarone treatment (i.e. amiodarone treatment 1 month prior until 1 month after cardioversion) is associated with a lower morbidity and a higher quality of life compared to continuous prophylactic amiodarone treatment while atrial fibrillation is still effectively suppressed.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Symptomatic persistent atrial fibrillation for at least 48 hours- 1 year (present episode).
  • Older than 18 years of age.
  • Ventricular rate during AF > 75 beats per minute, documented on rest-ECG without rate control.

Who cannot join

  • Contra indications for amiodarone (severe chronic obstructive pulmonary disease or QTc > 440ms).
  • History of relapse of AF during adequate amiodarone treatment (i.e. adequate amiodarone and desethylamiodarone plasma levels).
  • Concomitant treatment with class I or III antiarrhythmic drugs. Amiodarone should not have been used during the last 3 months.

About this study

Official title: Continuous Versus Episodic Prophylactic Treatment With Oral Amiodarone for the Prevention of Permanent Atrial Fibrillation: a Randomized Study on Morbidity and Quality of Life

Our hypothesis is that episodic amiodarone treatment (i.e. amiodarone treatment 1 month prior until 1 month after cardioversion) is associated with a lower morbidity and a higher quality of life compared to continuous prophylactic amiodarone treatment while atrial fibrillation is still effectively suppressed. The latter means that at the end of the study permanent atrial fibrillation is prevented in comparable percentage of patients (70%) in both treatment strategies. However, this will be accomplished at the cost of a higher number of electrical cardioversions (2-3) in the episodic treatment group compared to the continuous treatment group.

Read the detailed description

Primary objective

To determine differences in adverse event rates between patients with persistent atrial fibrillation who are randomized to episodic amiodarone treatment (EAT) strategy and patients who are randomized to continuous amiodarone treatment (CAT) strategy, while atrial fibrillation is still effectively suppressed.

Adverse events can be related to:

  1. amiodarone use
  2. atrial fibrillation itself or underlying heart disease.

Secondary objective

To determine differences in quality of life between patients with persistent atrial fibrillation who are randomized to the EAT strategy and patients who are randomized to the CAT strategy.

Being tested
amiodarone

What participants receive

  • amiodaroneDrug

What is being measured

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

  1. Adverse events related to amiodarone use and/or atrial fibrillation itself or underlying heart disease

Secondary outcomes (2)
  1. Quality of life

  2. Number of patients with permanent AF at the end of the study

Questions about this trial

What is this clinical trial studying?

A study testing amiodarone in people with Persistant Atrial Fibrillation, run by University Medical Center Groningen at 1 site 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 5 inclusion and 21 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 22 Mar 2007. 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 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. 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?

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?

Adverse events related to amiodarone use and/or atrial fibrillation itself or underlying heart disease. 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 NCT00392431, 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 22 Mar 2007.
