REGENXBIO's retinal disease program focuses on developing gene therapies for prevalent conditions like wet age-related macular degeneration (wet AMD). The lead product candidate, RGX-314, is currently in Phase III clinical trials, utilizing the NAV Technology Platform to deliver a gene encoding an anti-VEGF antibody directly to the eye. This approach aims to provide long-term therapeutic protein production, reducing the need for frequent intravitreal injections. The company is also exploring suprachoroidal delivery methods to enhance treatment efficacy and patient convenience. Future opportunities include expanding the pipeline to address other retinal disorders and improving delivery technologies for enhanced gene expression and safety.

This segment is dedicated to developing gene therapies for lysosomal storage disorders (LSDs), a group of rare genetic diseases. Key programs include RGX-121 for mucopolysaccharidosis type II (MPS II) and RGX-111 for mucopolysaccharidosis type I (MPS I), both in Phase I/II clinical trials. These therapies utilize the NAV Technology Platform to deliver genes encoding deficient enzymes to cells, aiming to correct the underlying metabolic defects. The focus is on improving neurological outcomes and overall quality of life for patients with these debilitating conditions. Future opportunities involve expanding the pipeline to address other LSDs and optimizing gene delivery to the central nervous system for enhanced therapeutic effects.

REGENXBIO's neuromuscular disease program is focused on developing gene therapies for conditions like Duchenne muscular dystrophy (DMD). RGX-202, currently in Phase I/II clinical trials, utilizes the NAV Technology Platform to deliver a gene encoding a novel microdystrophin protein to muscle cells. This approach aims to improve muscle function and slow disease progression in DMD patients. The company is also developing RGX-181 for late-infantile neuronal ceroid lipofuscinosis type II disease (CLN2 disease), a preclinical program. Future opportunities include optimizing gene delivery to muscle tissue, expanding the pipeline to address other neuromuscular disorders, and exploring combination therapies for enhanced therapeutic outcomes.
