About This Trial

Arrhythmogenic right ventricular dysplasia (ARVD) is a rare cardiomyopathy characterized by the progressive replacement of cardiomyocytes by fatty and fibrous tissue in the right ventricle (RV). These infiltrations lead to cardiac electrical instability and ventricular arrhythmia. Current treatment for ARVD is empirical and essentially based on treatment of arrhythmia. Thus, there is no validated treatment that will prevent the deterioration of the RV function in patients with ARVD. The investigator's hypothesis is that the use of anti-fibrotic medications will prevent or at least reduce the deterioration of the RV function. The aim of this project is to evaluate the effect of spironolactone, a Potassium-sparing diuretic on ventricular myocardial remodeling and on arrhythmia burden in patients with ARVD. The trial is a double-blind parallel multicenter prospective randomized phase II drug study. Patients will be randomized in the two groups: spironolactone or placebo. 13 centers in France will enroll the 120 patients (60 per group). Patients will be followed for 3 years (6 months, 1 year and 3 years) with all examinations (ECG, HA ECG, 24-hour Holter, trans-thoraciqc echocardiography (TTE), biological analyses) according to standard of care. A decrease in right and/or left ventricular deterioration and in arrhythmia burden are expected in ARVD patients treated with spironolactone. This reduction will improve the quality of life of patients and will reduce the number of hospitalizations and the risk of terminal heart failure.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Arrhythmogenic Right Ventricular Dysplasia and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 120 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Arrhythmogenic Right Ventricular Dysplasia subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT03593317), the sponsor (Hospices Civils de Lyon), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?
