About this study

Official title: Ablation Versus Medical Therapy in Patients With Coronary Artery Disease and Sustained Ventricular Tachycardia Randomized Trial (VeTAMed)

This study aims to compare antiarrhythmic drug therapy with catheter ablation using the SmartTOUCH catheter (Biosense Webster Inc.) as treatment for patients with ventricular tachycardia and coronary artery disease

Read the detailed description

This is a multicenter, randomized prospective cohort study to compare the impact of catheter ablation with antiarrhythmic drug therapy for treating patients with sustained ventricular tachycardia (VT) and coronary artery disease. Patients that meet all inclusion criteria and no exclusion criteria will be recruited to the study cohort. After baseline measurements are taken, patients will be randomized in a 2:1 fashion to either undergo radiofrequency catheter ablation or receive antiarrhythmic drug therapy (amiodarone or sotalol). The in-clinic appointments include: enrollment, baseline, intervention, and follow-up every three months for one year post-ablation. At each follow-up visit, electrogram (ECG) and Holter monitoring tests will be performed to measure any episodes of ventricular tachyarrhythmia. Furthermore, interrogation of the patient's implantable cardioverter defibrillator (ICD) will be performed at all follow-up visits to detect any episodes of ventricular tachyarrhythmia that required antitachycardia pacing (ATP) or shocks.

Being tested
Catheter Ablation, Medical therapy (sotalol or amiodarone)

What participants receive

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

  • Catheter AblationProcedure or surgery

    Also called Ablation of:, - Ischemic ventricular tachycardia, - Sustained monomorphic ventricular tachycardia, - Clinical ventricular tachycardia

    Catheter ablation of ventricular tachycardia will employ three-dimensional mapping Fast Anatomical Mapping or CARTOSOUND technology (Biosense Webster Inc.), and the Thermocool Navistar catheter (Biosense Webster Inc.).

  • Medical therapy (sotalol or amiodarone)Drug

    Also called Sotalol - Betapace, Betapace AF, Sotalex, Sotacor

    Patients will be tiered to one of two possible antiarrhythmic drugs (sotalol or amiodarone).

What is being measured

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

  1. Recurrence of Ventricular Tachycardia

    Number of any appropriate ATPs/shocks and/or presentations of sustained (>30sec) VT on Holter or ECG recording at 3, 6, 9 and 12 months after intervention

    Measured: 1 year

Secondary outcomes (6)
  1. Time to First Shock/ATP for VT or to First Presentation of Sustained VT

    Change in time to first ATP/shock or presentation of sustained (>30sec) VT on Holter or ECG recording at 3, 6, 9 and 12 months after intervention

    Measured: 1 year

  2. Total mortality

    Change in mortality status at 3, 6, 9 and 12 months after intervention

    Measured: 1 year

  3. Sudden cardiac death

    Change in sudden cardiac death status at 3, 6, 9 and 12 months after intervention

    Measured: 1 year

  4. Syncope

    Change in syncope status at 3, 6, 9 and 12 months after intervention

    Measured: 1 year

  5. Number of hospitalizations

    Change in number of hospitalizations at 3, 6, 9 and 12 months after intervention

    Measured: 1 year

  6. QOL measures

    Change in QOL measures at 6 and 12 months after intervention

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Catheter Ablation and Medical therapy (sotalol or amiodarone) in people with Ventricular Tachycardia and Coronary Artery Disease, run by Newmarket Electrophysiology Research Group Inc.

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 22 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: withdrawn, as of the sponsor's last update on 27 Jan 2015. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Recurrence of Ventricular Tachycardia (time frame: 1 year). 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 27 Jan 2015.
