Recruiting PHASE1 Catecholaminergic Polymorphic Ventricular Tachycardia

New treatment option for Catecholaminergic Polymorphic Ventricular Tachycardia

Official title A Study of SGT-501 Gene Therapy in Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)

ClinicalTrials.gov ID: NCT07148089

What this study is testing

What is SGT-501?

SGT-501 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for catecholaminergic polymorphic ventricular tachycardia.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This is a Phase 1b, Multicenter, Open-Label, Dose Finding Study to Investigate the Safety and Tolerability of a Single Intravenous Dose of SGT-501 in participants with catecholaminergic polymorphic ventricular tachycardia (CPVT). The first-in-human (FIH) safety study will focus on obtaining safety data in adult participants.
  • Phase 1: an early, usually small safety study

Who can join
  • Type of Participant and Disease Characteristics:
  • Clinical diagnosis of CPVT, based on documented history of polymorphic or bidirectional non-sustained ventricular tachycardia with exercise or ventricular ectopy in a pattern consistent with CPVT on EST.
  • Central Screening laboratory determination of a RYR2 variant that is pathogenic or likely pathogenic for CPVT.
