Study summary

The goal of this study is to describe the natural history and clinical events for patients who have Arrhythmogenic Cardiomyopathy with Pathogenic Plakophilin-2 Variants (PKP2-ACM) managed with standard of care.

Read the detailed description

This is an observational study with both retrospective and prospective data collection. The study is designed to describe the natural history of PKP2-ACM including the signs and symptoms, key clinical events, and impact of the disease on quality of life. A hybrid (retrospective and prospective data collection) approach is being taken with the aim of achieving robust and longitudinal data generation.

Study population

Patients 12 years of age and over with confirmed PKP2-ACM.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

Patients must meet all the following criteria (and none of the exclusion criteria) to be eligible for study participation:

  1. Male or female age 12 years or older at the time of providing (i.e., ICF provision).
  2. Capable and willing to provide signed informed consent and/or assent, which includes compliance with the requirements and restrictions listed in the ICF and protocol.
  3. Clinical diagnosis of arrhythmogenic cardio myopathy (ACM)
  4. Documentation of a pathogenic or likely pathogenic variant in PKP2 by a CLIA-certified genetic testing laboratory
  5. History of ICD implantation ≥6 months prior to ICF provision
  6. by echocardiogram or cardiac magnetic resonance (CMR) ≥50% at ≤12 months prior to ICF provision

Exclusion criteria

Exclusion Criteria

Patients meeting any of the following criteria are excluded from study participation:

  1. Gene testing indicates that the subject's arrhythmia or cardiomyopathy may be related to a genetic etiology other than PKP2 truncating variant.
  2. Concurrent participation in any other clinical investigation involving use of an agent that could confound results of this study.
  3. Previous participation in a study of gene transfer or gene editing.
  4. Class IV heart failure.
  5. Presence or requirement for mechanical circulatory support (MCS) or predicted need for MCS or heart transplantation within 6 months of enrollment.
  6. Prior cardiac or other organ (lung, liver, other) transplantation.
  7. Pacemaker dependent rhythm documented, as assessed by the principal investigator ≤12 months prior to enrollment.
  8. Positive (HIV) antibody test.
  9. Unwillingness to comply with study procedures, including follow-up as specified by this protocol, or unwillingness to fully cooperate with the investigator.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
