Trial summary

This study is performed to assess if PET-MR imaging can improve treatment of patients with irregular heart rate and heart failure. Heart failure occurs when the heart muscle is too weak to do his work correctly. Irregular heart rate can be related to numerous diseases. Read more about this study

About this study

This study is performed to assess if PET-MR imaging can improve treatment of patients with irregular heart rate and heart failure. Heart failure occurs when the heart muscle is too weak to do his work correctly. Irregular heart rate can be related to numerous diseases. One category of irregular heart rate is called ventricular arrhythmia. It is often seen in patients who have had a heart attack. This type of arrhythmia can be dangerous and can cause sudden death. To prevent these arrhythmias, doctors can perform procedures that burn the source of arrhythmia in the heart muscle. This is called ablation. Unfortunately, ablation does not fix the problem in 100% of patients and some will still have the arrhythmia requiring repeated procedure. The purpose of this study is to find new ways of guiding the doctors performing ablation, hoping to improve the success rate of the procedure.

What participants receive

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

  • 18F-TPPDrug

    Also called 18F-BFPET

    Imaging with 18-F-TPP (18F-BFPET)

Study groups in NCT03265431
Study groupRoleWhat they receive
ControlActive comparatorNormal subjects without history of cardiac disease or arrhythmia
Receives: Drug: 18F-TPP
ArrhythmiaExperimentalThis cohort consist of patients with history of recurrent VT and scheduled for EAM-guided catheter ablation as part of their clinical treatment
Receives: Drug: 18F-TPP
Treatment FailureExperimentalA subset of the Arrhythmia cohort, this group will undergo a second imaging session. This subset corresponds to patients from the Arrhythmia cohort presenting with recurrent ventricular arrhythmia following initial EAM-guided catheter ablation and requiring repeated ablation. It is estimated that 30% of the Arrhythmia cohort patients will require repeat ablation based on rate of repeat ablation procedures at MGH. T
Receives: Drug: 18F-TPP

What is being measured

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

  1. TPP imaging in Ventricular Arrhythmia

    Establish imaging patterns allowing prediction of VT ablation failure

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 18F-TPP in people with Arrhythmias, Cardiac, run by Massachusetts General Hospital at 1 site in United States.

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 32 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 30 Jan 2024. 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

TPP imaging in Ventricular Arrhythmia (time frame: 5 years). 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 NCT03265431, which also lists 1 linked publication.

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 30 Jan 2024.
