Active clinical trials for "Myocarditis"

Evaluating the long-term therapeutic effects of hydroxychloroquine(compared to glucocorticoid therapy alone) in patients with inflammatory cardiomyopathy--a multicenter randomized controlled study

The primary aim is to test whether abatacept, as compared to placebo, is associated with a reduction in major adverse cardiac events (MACE) among participants hospitalized with myocarditis secondary to an immune checkpoint inhibitor (ICI). The primary outcome, MACE, is a composite of first occurrence of cardiovascular death, non-fatal sudden cardiac arrest, cardiogenic shock, significant ventricular arrythmias, significant bradyarrythmias, or incident heart failure.

Multi-center, double-blind, placebo-controlled, parallel group design. Patients with myocarditis will be screened and, if eligible, randomized within 10 days of the diagnostic CMR to CardiolRx or placebo. CardiolRx is pharmaceutically produced Cannabidiol and is free of tetrahydrocannabinol (THC<5 ppm). The treatment period is 12 weeks; a last follow-up visit is scheduled one week after the last treatment, 13 weeks after randomization. Study assessments include Cardiac Magnetic Resonance imaging (CMR), ECG monitoring, the Kansas City Cardiomyopathy Questionnaire (KCCQ), the Columbia-Suicide Severity Rating Scale (C-SSRS) as well as physical exams and laboratory tests. The primary and secondary outcome parameters are measured by CMR. Additional outcomes include clinical endpoints and changes in inflammatory and biomarkers.

The study is aimed at studying the direct efficacy of mycophenolate mofetil (mycophenolate mofetil, CellCept, Genentech, N015393/02, 12.08.2009) (in combination with corticosteroids (methylprednisolone, Metypred, Orion, 003467, 26.02.2016)) in the treatment of lymphocytic myocarditis: the effect on symptoms, structural and functional parameters of the heart, on the outcomes of lymphocytic myocarditis: mortality, the need for transplantation, other surgical interventions, the incidence of unwanted side effects, and forced cancellation (replacement) of the drug. To compare the data on the efficacy and safety of therapy with mycophenolate mofetil (in combination with corticosteroids) with the standard regimen of therapy for lymphocytic myocarditis (corticosteroids in combination with azathioprine), including in cases of forced replacement of drugs with each other.

Immune-checkpoint-inhibitors (ICI) have revolutionized treatment for 20 cancer types. They unleash anti-tumor immune responses. Unfortunately, in 0.36-1.23% of patients, this activation can also lead to lethal immune-related adverse events (irAEs) that can affect any organ. Among those irAEs, ICI-induced myocarditis are the most frequently fatal with death rate reaching 50% in a large case-series of over 100 patients. This study is a dose-finding Phase II trial where 3 abatacept IV regimen (A-10 mg/kg; B-20 mg/kg and C-25 mg/kg every week) will be tested aiming at reaching promptly (after the first dose) and sustainably a CD86RO≥80% during the first 3 weeks of ICI-myocarditis management. The main objective is to find the lowest dose required to achieve a circulating monocytes CD86RO≥80% within the first week of treatment and sustainably over three weeks. The target population is all adult patients with cancer (all cancer types) treated by immune checkpoint inhibitors (anti-PD1, anti-PDL1, anti-CTLA4 monotherapies or combination) and presenting drug-induced myocarditis.

This is a phase III, multi-center international, single blind randomized controlled trial to test the efficacy of pulsed intravenous (IV) methylprednisolone versus standard therapy on top of maximal support in patients with Acute myocarditis (AM).

Introduction: Coronavirus disease 2019 (COVID-19) remains a major health issue resulting in >800,000 deaths as of 30th August 2020. A concerning discovery of COVID-19 is the involvement of the myocardium. Several case studies including one from our group (recent study publication in JACC Cardiovascular Imaging led by the principal investigator of this grant application) have demonstrated subclinical myocardial inflammation in patients using cardiac magnetic resonance imaging (CMR) who have recovered from COVID-19. Furthermore at a cellular level, a recent autopsy study indicated that the severe acute respiratory syndrome coronavirus-2 is present in the myocardial tissue. The study further described invasion and viral progeny occurring in the myocardial interstitial cells and as such is a concerning development with the longer-term implications being unknown. These concerns have been noticed by the cardiology and non-cardiology medical community, with some expressing concerns of a new cause for cardiomyopathy and heart failure secondary to COVID-195. Therefore, it is critical that further studies are conducted to determine the longer-term outcome for patients.

The goal of this prospective, multicentre study is to investigate short- and long-term cardiovascular effects in cancer patients treated with immune checkpoint inhibitors (ICIs). The main question[s] it aims to answer are: To investigate troponin and NT-proBNP values in patients receiving ICIs and their association with ICI-induced CV abnormalities and MACEs. Study the calcium score, systolic, and diastolic (dys)function. Evaluate associations between patient/disease characteristics / transthoracic echocardiography parameters / electrocardiography parameters and troponin / NT-proBNP levels. Participants will be closely monitored by performing the following additional visits and testing: Chest CT scan prior to treatment start, after 12 and 24 months. Consultation with a cardiologist at baseline, 3, 6, 12 and 24 months, who will perform an electrocardiogram and echocardiogram. One additional blood sample prior to treatment start, after 3, 6, 12 and 24 months. An extra blood sample could be taken in case of sudden heart problems. Non-invasive endothelial function tests prior to treatment start, after 12 and 24 months.

In this study, patients with endocardial myocardial biopsy were selected to observe the safety of the operation, and pathological examination was performed. If necessary, special tests such as viral examination, mass spectrometry and molecular biology were performed to confirm the diagnosis, and follow-up was performed.

The study will focus on cardiac blood and imaging biomarkers to facilitate early recognition of patients at risk for myocardial injury after COVID-19 vaccination. Ultimately, the intention is to identify patients at risk, reduce adverse events, and determine the need for longer-term follow-up in patients with myocardial injury after vaccination.
