Anti-TREK-1 Autoantibodies in SCVF: A Multicenter Look

Official title: Circulating Anti-TREK-1 Autoantibodies as Diagnostic and Prognostic Biomarkers in Short-Coupled Ventricular Fibrillation

Run by Institut universitaire de cardiologie et de pneumologie de Québec, University Laval · NCT06943365 · Data updated 2026-11-12

Researchers are testing whether anti-TREK-1 autoantibodies are linked to short-coupled ventricular fibrillation and if they can help diagnose or predict outcomes in adults with SCVF.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with a diagnosis of SCVF who are willing to provide informed consent.

Probably not a fit

SCVF patients without anti-TREK-1 antibodies or without a clear link to arrhythmia risk may not see a diagnostic or prognostic benefit.

What this trial studies

This translational, multicenter observational study investigates whether circulating anti-TREK-1 autoantibodies serve as biomarkers for SCVF. It includes repeat plasma screenings and genetic haplotype analysis, alongside functional studies in patient-derived cardiac cells and single-cell transcriptomics to understand TREK-1’s role in arrhythmogenesis. The study design combines observational biomarker work with laboratory experiments to connect antibody presence with cellular mechanisms. Participants are adults diagnosed with SCVF, enrolled across multiple Canadian centers, with data collection focused on diagnostic and prognostic implications. No interventional treatment is being tested; the emphasis is on biomarker validation and mechanistic insight.

Why it matters

Potential benefit: If successful, the findings could lead to a blood test that helps diagnose SCVF and predict risk, guiding management and monitoring.

How similar studies have gone: Preliminary data suggest a link between TREK-1 antibodies and SCVF, but the translational, multicenter validation is still needed.
