About SGT-003
SGT-003 is an investigational gene therapy containing a novel microdystrophin construct and a proprietary, next-generation capsid, POLARIS-101™ (formerly known as AAV-SLB101), which was rationally designed to target integrin receptors, and has shown enhanced cardiac and skeletal muscle transduction with decreased liver targeting in data from the Phase 1/2 INSPIRE DUCHENNE clinical trial and in nonclinical studies. SGT-003’s microdystrophin construct uniquely includes the R16/17 domains, which localize nNOS to the muscle. Nonclinical studies have shown that nNOS can improve blood flow to the muscle thereby reducing muscle breakdown from ischemia and muscle fatigue. Together, these design features suggest that SGT-003 could be a potential best-in-class investigational gene therapy for the treatment of Duchenne.
About POLARIS-101™
POLARIS-101™ is Solid’s proprietary, rationally engineered capsid developed for enhanced skeletal muscle and cardiac tropism and reduced liver biodistribution. Preclinical studies have demonstrated increased transduction speed, enhanced skeletal and cardiac muscle delivery, decreased liver biodistribution and improved efficiency compared with first-generation capsid benchmarks. POLARIS-101 is being clinically evaluated as the delivery capsid for SGT-003, Solid’s investigational gene therapy for Duchenne muscular dystrophy, in the Phase 1/2 INSPIRE DUCHENNE clinical trial (NCT06138639) and the Phase 3 IMPACT DUCHENNE clinical trial (NCT07160634).
Solid is developing POLARIS-101 as part of a broader gene therapy technology platform that includes proprietary manufacturing and other enabling technologies intended to support the development of genetic medicines for neuromuscular and cardiac diseases.
About Solid's Advanced Manufacturing Platform
Solid’s proprietary, advanced manufacturing technologies were developed to optimize productivity and product quality for POLARIS-101™, Solid’s proprietary, rationally engineered myotropic capsid. The manufacturing platform enables efficient, regulatory-compliant manufacturing while maintaining high-quality product attributes. Solid has optimized more than 200 operating parameters for upstream and downstream unit operations supported by best-in-class plasmid design, raw material selection and manufacturing processes designed for scalability, transferability and implementation across diverse production environments.
About Solid Biosciences
Solid Biosciences is a precision genetic medicine company focused on advancing a portfolio of gene therapy candidates targeting rare neuromuscular and cardiac diseases, including SGT-003 for Duchenne muscular dystrophy (Duchenne), SGT-212 for Friedreich’s ataxia (FA), SGT-501 for catecholaminergic polymorphic ventricular tachycardia (CPVT), SGT-601 for TNNT2-mediated dilated cardiomyopathy and additional fatal, genetic cardiac diseases. The Company is also focused on developing innovative libraries of genetic regulators and other enabling technologies with promising potential to significantly impact gene therapy delivery cross-industry. Solid is advancing its diverse pipeline and delivery platform in the pursuit of uniting experts in science, technology, disease management and care. Patient-focused and founded by those directly impacted by Duchenne, Solid’s mission is to improve the daily lives of patients living with devastating rare diseases.
