Trial summary

Myocarditis or inflammatory cardiomyopathy refers to inflammation of the heart muscle (the myocardium). Sarcoidosis is a multisystem granulomatous disorder that may involve the heart, causing inflammation, and potentially resulting in complications including arrhythmia and sudden death.

About this study

Official title: Diagnostic and Prognostic Significance of Combined PET/MRI in Inflammatory Cardiomyopathies and Sarcoidosis

Myocarditis or inflammatory cardiomyopathy refers to inflammation of the heart muscle (the myocardium). Sarcoidosis is a multisystem granulomatous disorder that may involve the heart, causing inflammation, and potentially resulting in complications including arrhythmia and sudden death. The objective of this study is to evaluate the diagnostic and prognostic significance of simultaneous combined 18F-FDG PET and cardiac MRI imaging in the evaluation of inflammatory cardiomyopathies including cardiac sarcoidosis. Combined PET/MRI imaging may allow for detection and quantification of active myocardial inflammation as well as chronic fibrosis and scarring. Results of this study may allow for earlier detection of cardiac inflammation when compared with methods in current clinical use, and may lead to better understanding of the disease processes contributing to adverse outcomes. Elucidation of imaging findings associated with future adverse event risk may impact patient management such as providing an indication for pacemaker or defibrillator implantation, or escalation of medical therapy.

Read the detailed description

Myocarditis or inflammatory cardiomyopathy refers to inflammation of the myocardium. Sarcoidosis is a multisystem granulomatous disorder of unknown etiology, which can result in myocardial inflammation. Approximately 5% of patients with sarcoidosis have clinically apparent cardiac involvement, yet autopsy series indicate that cardiac involvement is present in up to 25% of cases. This discrepancy suggests that cardiac sarcoidosis may be under-diagnosed in clinical practice. Recent studies have demonstrated high diagnostic accuracy of both cardiac MRI and 18F-labelled fluoro-2-deoxyglucose (FDG) PET for detection of cardiac involvement. However, cardiac MRI may fail to identify areas of active inflammation even with fluid sensitive T2-weighted sequences.

Fasting 18F-FDG positron emission tomography (PET) has been shown to identify early cardiac sarcoidosis with relatively high sensitivity. To date, simultaneous PET/MRI evaluation of cardiac inflammation and sarcoidosis has only been described in limited case reports. The objective of the proposed research is to evaluate the utility of simultaneous PET/MRI imaging in patients with cardiac sarcoidosis and other inflammatory cardiomyopathies.

What is being measured

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

  1. The incremental value of combined 18F-FDG PET and cardiac MRI imaging in the evaluation of patients with suspected cardiac sarcoidosis or cardiac inflammation

    Patients will undergo standard clinical evaluation using modified consensus guidelines for the diagnosis of sarcoidosis. Following enrolment, patients will also undergo parallel assessment for cardiac involvement by PET/MRI. Comparison of cardiac involvement identified by modified consensus criteria and PET/MRI will be performed.

    Measured: Completion of enrollment, an average of two years

Secondary outcomes (2)
  1. The differences in circulating plasma biomarkers between cardiac with suspected cardiac sarcoidosis and healthy people

    A cohort of 25 healthy volunteers will be recruited for comparison of patients with suspected cardiac sarcoidosis. Biomarkers such as microRNA will be analyzed in both groups.

    Measured: Completion of enrollment, an average of two years

  2. The prognostic significance of PET-MRI imaging findings in patients with cardiac inflammation

    Clinical follow-up to track adverse events to validate imaging findings and determine their prognostic significance.

    Measured: Through study completion, an average of three years

Questions about this trial

What is this clinical trial studying?

An observational study of Inflammatory Cardiomyopathy and Sarcoidosis, run by University Health Network, Toronto 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 1 inclusion and 1 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 28 May 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 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?

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?

The incremental value of combined 18F-FDG PET and cardiac MRI imaging in the evaluation of patients with suspected cardiac sarcoidosis or cardiac inflammation (time frame: Completion of enrollment, an average of two 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 NCT03356756, 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 28 May 2024.
