About the Organization

REGENXBIO is a leading clinical-stage biotechnology company seeking to improve lives through the curative potential of gene therapy. REGENXBIO's NAV® Technology Platform, a proprietary adeno-associated virus (AAV) gene delivery platform, consists of exclusive rights to more than 100 novel AAV vectors, including AAV7, AAV8, AAV9 and AAVrh10. REGENXBIO and its third-party NAV Technology Platform Licensees are applying the NAV Technology Platform in the development of a broad pipeline of candidates in multiple therapeutic areas.

Our gene therapy product candidates are designed to deliver genes to cells to address genetic defects or to enable cells in the body to produce therapeutic proteins that are intended to impact disease. Through a single administration, our gene therapy product candidates are designed to provide long-lasting effects, potentially significantly altering the course of disease and delivering improved patient outcomes. Our lead product candidates are RGX-314 for the treatment of wet age-related macular degeneration (wet AMD), RGX-501 for the treatment of homozygous familial hypercholesterolemia (HoFH), RGX-111 for the treatment of Mucopolysaccharidosis Type I (MPS I) and RGX-121 for the treatment of Mucopolysaccharidosis Type II (MPS II).
