Cell Free DNA Testing for Myocarditis
(cfDNA in CS Trial)
Trial Summary
What is the purpose of this trial?
Sarcoidosis is a multisystem granulomatous disease of unknown cause that can affect any organ in the body, including the heart. Granulomatous myocarditis can lead to ventricular dysfunction and ventricular arrhythmias causing significant morbidity and mortality. Immunosuppressive therapy (IST) has been shown to reverse active myocarditis and preserve left ventricular (LV) function and in some cases improve LV function. In addition, IST can suppress arrhythmias that develop due to active myocarditis and prevent the formation of scar. The potential role of cardiac biomarkers, including brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), and cardiac troponins, in detecting active myocarditis is limited and studies have been disappointing. At present, there are no biomarkers to detect active myocarditis and the use of advanced imaging modalities (FDG-PET) for assessing and monitoring active myocarditis is not feasible or practical and is associate with high radiation exposure. As such, a biomarker that is reflective of active myocarditis and that is cardiac specific will assist physicians in assessing the presence of active myocarditis to guide therapeutic decisions and to assess response to therapy which can limit further cardiac damage. Cell free DNA (cfDNA) are fragments of genomic DNA that are released into the circulation from dying or damaged cells. It is a powerful diagnostic tool in cancer, transplant rejection and fetal medicine especially when the genomic source differs from the host. A novel technique that relies on tissue unique CpG methylation patterns can identify the tissue source of cell free DNA in an individual reflecting potential tissue injury. We will be conducting a pilot study to explore the utility of this diagnostic tool to identify granulomatous myocarditis in patients with sarcoidosis.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot be on immunosuppressive therapy to participate.
What data supports the effectiveness of the drug Cell free DNA, Prednisone, Corticosteroids for myocarditis?
Corticosteroids, a part of the treatment, have been studied for viral myocarditis, showing some improvement in heart function but not in survival rates. A scoring system suggests that steroids may help certain patients with active myocarditis, but overall evidence does not strongly support their routine use.12345
Is Cell Free DNA Testing for Myocarditis safe for humans?
Research on corticosteroids, like prednisone, used in treating myocarditis shows they are generally safe, with no significant side effects reported in children and adults. However, the effectiveness of these treatments for myocarditis varies, and they are not routinely recommended for viral myocarditis.45678
How does cell-free DNA testing differ from other treatments for myocarditis?
Cell-free DNA testing for myocarditis is unique because it focuses on detecting DNA fragments in the blood to diagnose and monitor the condition, rather than directly treating it. This approach is different from traditional treatments like immunosuppressive therapy, which aim to reduce inflammation in the heart.457910

Eligibility Criteria
This trial is for non-smokers with sarcoidosis diagnosed by ATS/ERS criteria, experiencing active myocarditis confirmed by cMRI or cFDG-PET. It includes those undergoing cardiac intervention for acute coronary syndrome (STEMI) and healthy controls without cardiovascular risks or known cardiac disease. Excluded are smokers, those on immunosuppressive therapy, hemodynamically unstable patients, and anyone with other known cardiac diseases.Inclusion Criteria
