A Phase 1, Dose Escalation Trial of RP-A601 in Subjects With PKP2 Variant-Mediated Arrhythmogenic Cardiomyopathy (PKP2-ACM)
A Phase 1 Dose Escalation Trial Evaluating an Intravenously Administered Recombinant Adeno-Associated Virus Serotype rh.74 (AAVrh.74) Vector Containing the Human Plakophilin-2a (PKP2a) Coding Sequence (RP-A601; AAVrh.74-PKP2a) in Subjects With Arrhythmogenic Cardiomyopathy Arising From Pathogenic PKP2 Variants (PKP2-ACM)
