Solid Biosciences Receives FDA Fast Track Designation for SGT-501 First-in-Class Gene Therapy for Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)

Solid Biosciences Inc., which acquired UF startup AavantiBio, announced that it received Fast Track designation from the U.S. Food and Drug Administration (FDA) for SGT-501, the Company’s novel, AAV-based investigational gene therapy for the treatment of catecholaminergic polymorphic ventricular tachycardia (CPVT). SGT-501 will deliver a functional, full-length, codon-optimized copy of the human cardiac calsequestrin (CASQ2) gene to cardiac muscle cells, an approach intended to address the underlying ryanodine receptor (RYR2) instability and calcium dysregulation seen in CPVT, thereby normalizing cardiac rhythm in diastole.

Fast Track designation is granted to products that are developed to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs. This designation is intended to facilitate development and expedite review of qualifying drugs. SGT-501 will benefit from this designation through more frequent interactions with the FDA along with the potential to be eligible for priority review.
