About this trial

This is a multicenter, non-interventional study to observe the natural progression of the disease and to study the prevalence of pre-existing antibodies to AAV9 used for gene therapy in a population of patients with PKP2 gene-associated ARVC. Participation from all patients is encouraged regardless of interest in or eligibility for gene therapy.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Ages 14-65 years, inclusive, at the time of consent

Pathogenic or likely pathogenic PKP2 gene mutation

Diagnosed with ARVC and meet 2010 Modified Task Force Criteria for ARVC as affected.

Functioning ICD

Disqualifiers

Currently receiving systemic immunosuppressive therapy, cytotoxic chemotherapy, immunoglobulin therapy or monoclonal antibody therapy

History of clinically significant liver disease, hepatitis B virus, hepatitis C virus, human immunodeficiency virus, or tuberculosis infection

Previously dosed with any investigational or approved gene therapy product at any time

Concurrent participation in another interventional clinical trial unless approved by the Sponsor. Participation in a noninterventional study may be allowed at the investigator's discretion.

Trial population

Patients who are 14-65 years of age at the time of consent, and with confirmed mutations in PKP2 gene with a diagnosis of ARVC.
