This study evaluates TN-401, a gene therapy, for its safety and preliminary efficacy in adults with arrhythmogenic right ventricular cardiomyopathy associated with a PKP2 gene mutation. It enrolls adults aged 18 and older who carry a pathogenic PKP2 mutation, have preserved left ventricular function, and have a functioning implantable cardiac defibrillator. The study is in Phase 1 and is currently recruiting participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
