Trial summary

Stereotactic Arrhythmia Radioablation (STAR) ablation is a safe and feasible option for cardiomyopathy patients for management of refractory ventricular tachycardia. STAR can be performed with available cardiac imaging, prior mapping/electrogram information, and standard ECGs without a multi-electrode ECG vest. Read more about this study

About this study

Stereotactic Arrhythmia Radioablation (STAR) ablation is a safe and feasible option for cardiomyopathy patients for management of refractory ventricular tachycardia.

STAR can be performed with available cardiac imaging, prior mapping/electrogram information, and standard ECGs without a multi-electrode ECG vest.

Read the detailed description

Study Hypotheses:

  1. Stereotactic Arrhythmia Radioablation (STAR) ablation is a safe and feasible option for cardiomyopathy patients for management of refractory ventricular tachycardia.
  2. STAR can be performed with available cardiac imaging, prior mapping/electrogram information, and standard ECGs without a multi-electrode ECG vest.

Study Objectives:

  1. Evaluate the safety of STAR in a local cohort
  2. Estimate effectiveness of STAR in reducing VT burden

Study Design: Prospective single center, single arm, non-randomized trial.

Number of patients: 20 patients

Study Duration: Enrollment will occur over three years and at least minimum follow up of six months

Study Population: Adult patients with a cardiomyopathy and ventricular tachycardia who have failed conventional anti-arrhythmic management.

Primary safety endpoint: Any treatment-related serious adverse events in the first 90 days.

Primary efficacy endpoint: Reduction in VT episodes tracked by ICD with a six week blanking period.

Statistical methodology: Wilcoxon matched-pairs signed-ranks test to compare the number of treated episodes before and after.

Assessment of events: Adjudicated by study investigators

Economic Analysis: Costs and resources required for STAR .Compare costs between the patients undergoing STAR with conventional catheter-based VT ablation.

Receives: Radiation: Stereotactic Radioablation

What is being measured

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

  1. Efficacy of radiation treatment for VT reduction

    Reduction in VT burden tracked by ICD and defined as the difference between the number of ICD-treated VT/VF episodes comparing the 6 months prior to treatment to the 6 months after treatment.

    Measured: 6 month period before treatment to the 6 month period after ablation with a 6 week blanking period post-treatment.

  2. Safety composite endpoint of radiation treatment-related pericarditis, pneumonitis, changes in cardiac structures, function, and/or ICD function.

    Any treatment-related serious adverse events including pericarditis, radiation pneumonitis, deterioration in cardiac function, new or worsening cardiac valve dysfunction, and implantable cardioverter defibrillator malfunction.

    Measured: 90 days after treatment

Secondary outcomes (1)
  1. Overall mortality

    Six month survival after treatment

    Measured: Six months

Questions about this trial

What is this clinical trial studying?

A study testing Stereotactic Radioablation in people with Stereotactic Radioablation for Ventricular Tachycardia, run by University of Calgary at 1 site in Canada.

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 6 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: status not confirmed, as of the sponsor's last update on 15 Nov 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 Canada. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Vikas Kuriachan, MD (4039443282, vpkuriac@ucalgary.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Efficacy of radiation treatment for VT reduction (time frame: 6 month period before treatment to the 6 month period after ablation with a 6 week blanking period post-treatment.). The study lists 2 primary outcomes in all. 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 NCT04065802, 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 15 Nov 2022.
