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. Cohort 1 and Cohort 2 (optional for dose exploration) will include participants ≥ 18 years of age. Cohort 3 will include participants ≥ 7 to \< 18 years of age and will be initiated following data and safety monitoring board (DSMB) recommendations. Participants will be monitored for 5 years post-administration of SGT-501 including the active treatment period (1 year) and long-term follow-up (LTFU) (4 years) period.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Solid Biosciences (SLDB) is the sponsoring company for this trial. BiotechSign currently grades this company D (41/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
