This study evaluates RP-A601, a gene therapy, in adults with arrhythmogenic cardiomyopathy caused by variants in the PKP2 gene. Adults aged 18 and older who carry a disease-causing PKP2 variant and have a previously implanted cardiac device (ICD) may take part. The study is in Phase 1 and is currently enrolling participants.
