Regenxbio’s research focuses on one-time treatment modalities designed to deliver curative outcomes through precise genetic correction.
Core Technologies and NAV® Platform
At the heart of Regenxbio’s approach is its NAV® technology platform. This platform harnesses the unique properties of AAV vectors to facilitate targeted gene delivery. By providing a robust and versatile system for precision medicine, the NAV® platform underpins the company’s ability to develop therapies that address genetic disorders across a range of indications. The integration of exclusive AAV serotypes, including AAV7, AAV8, AAV9, and AAVrh10, ensures a high degree of specificity and efficiency in gene transduction, setting a strong technical foundation for its therapeutic candidates.
Clinical Programs and Pipeline
Regenxbio is advancing an array of gene therapy candidates through its diversified pipeline. The company’s programs span several high-need therapeutic areas:
- Neuromuscular Diseases: The RGX-202 program is designed to offer a one-time treatment for Duchenne muscular dystrophy, aiming to deliver a novel microdystrophin gene construct that closely mirrors the natural protein and supports muscle function.
- Neurodegenerative Diseases: The RGX-121 candidate targets mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome. This program focuses on addressing both the neurocognitive and systemic manifestations of the disease, employing a gene therapy approach that delivers a structurally normal enzyme to facilitate long-term cellular correction.
- Retinal Diseases: In collaboration with AbbVie, the ABBV-RGX-314 candidate is being developed for the treatment of wet age-related macular degeneration (AMD), diabetic retinopathy, and other chronic retinal conditions. This therapy is designed to provide a one-time intervention that mitigates the burden of frequent traditional treatments.
Each candidate within the pipeline is optimized for one-time administration, a distinctive feature that underscores Regenxbio’s innovative approach to gene therapy by potentially reducing treatment burdens while achieving sustained biological effects.
