About this study

Official title: Catheter Ablation Versus Amiodarone for Shock Prophylaxis in Defibrillator Patients With Ventricular Tachycardia: A Multi-center Randomized Trial

Implantable Cardioverter Defibrillators (ICDs) provide a shock or pacing therapy to bring back a normal heart beat when a patient experiences a dangerous abnormal heart rhythm such as ventricular tachycardia (VT). ICDs are very successful in bringing back a normal heart beat when VT occurs, but they do not prevent further dangerous heart rhythms from occurring. This study is designed to determine the best way to manage patients who have an ICD and who continue to have episodes of VT. There are two methods for treatment the VT: 1) Ablation, and 2) Medication.

An ablation procedure involves placing a flexible catheter (insulated wire) in the groin area and threading it into the heart. After the doctor has located the affected area responsible for the VT, radiofrequency energy is delivered by the power generator through the catheter to the inside of the heart. The radiofrequency energy ablates (burns) a small area of the heart tissue thought to cause the VT.

A medication called Amiodarone is an "anti-arrhythmic" prescribed to prevent abnormal heart rhythms from recurring.

The purpose of this study is to compare these two different methods for treating VT. Treatment with ablation and amiodarone are both considered the standard of care for patients with VT but they have not been compared directly in a study like this before.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AblationProcedure or surgery

    Also called VT ablation, ischemic VT ablation, catheter ablation, radiofrequency ablation

    Catheter based radiofrequency ablation for ischemic ventricular tachycardia scheduled to occur within 4 weeks after randomization

  • AmiodaroneDrug

    Also called Cordarone

    Amiodarone titrated to therapeutic levels as per standard of care and maintained on a dose of at least 200 mg (300 mg recommended) once a day for the duration of the study

What is being measured

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

  1. Number of Participants With Appropriate ICD Therapy, Slow VT or Sudden Cardiac Death

    Number of participants with a composite outcome of any of:

    1. Appropriate Implantable Cardioverter Defibrillator (ICD) therapy [Including antitachycardia pacing (ATP) and shocks]
    2. Slow ventricular tachycardia (VT) below ICD detection threshold leading to hospitalization or necessitates antiarrhythmic medications and/or catheter ablation
    3. Sudden Cardiac Death

    Measured: From 30 days following randomization until final follow-up visit

Secondary outcomes (2)
  1. Number of Participants With (a) Ablation or Amiodarone Complications, (b) Inappropriate Shocks From ICD, or (c) Need for Concomitant Use of Sotalol, Dofetilide, Azimilide or Class 1 Antiarrhythmic Agents in Either Arm of the Trial.

    Number of Participants with (a) Ablation or Amiodarone Complications, (b) Inappropriate Shocks from ICD, or (c) Need for Concomitant use of Sotalol, Dofetilide, Azimilide or Class 1 Antiarrhythmic agents in either arm of the trial.

    Measured: from randomization until final follow-up

  2. Quality of Life Score

    Quality of life score in each treatment arm using the EQ-5D Visual Analogue Scale (VAS) (euroqol.org). The EQ-5D VAS is a patient reported scale from 0 to 100 on which the patient rates how good or bad their health is today with 100 being the best health they can imagine and 0 being the worst health they can imagine.

    Measured: At 6 months follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ablation and Amiodarone in people with Defibrillators, Implantable and Tachycardia, Ventricular, run by Population Health Research Institute at 11 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 29 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States, Canada, China. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Jan 2020). 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 Appropriate ICD Therapy, Slow VT or Sudden Cardiac Death (time frame: From 30 days following randomization until final follow-up visit). 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 29 Jan 2020.
