NAV® Technology Platform

REGENXBIO’s gene therapy product candidates deliver genes to cells using adeno-associated virus (AAV) vectors, which are nonreplicating viral delivery vehicles that are not known to cause disease. Our product candidates all utilize viral vectors from our proprietary gene delivery platform, which we call our NAV Technology Platform.


Our NAV Technology Platform consists of exclusive rights to AAV7, AAV8, AAV9, AAVrh10 and over 100 other novel AAV vectors (NAV Vectors). We currently have exclusive rights to over 100 patents and patent applications worldwide covering our NAV Vectors, including composition of matter claims for AAV7, AAV8, AAV9 and AAVrh10, as well as methods for their manufacture and therapeutic uses. We believe this patent portfolio forms a strong foundation for our current programs and with our ongoing research and development, we expect to continue to expand this robust patent portfolio.


The foundation of our NAV Technology Platform was discovered in an effort to identify next generation AAV vectors that could overcome the limitations of earlier generation AAV vectors (AAV1 through AAV6). We believe the key benefits of NAV Vectors over earlier generation AAV vectors potentially include:


• Higher gene expression
• Longer-term gene expression
• Broad and novel tissue selectivity
• Lower immune response
• Improved manufacturability

We believe our NAV Technology Platform is proving to be a significant advancement over earlier AAV vectors in delivering these therapies. Based on data derived from third-party clinical studies and animal models using our NAV Vectors, we believe our NAV Technology Platform possesses unique, beneficial properties that are not seen in earlier generation AAVs. We believe that our NAV Technology Platform, which underpins our internal development programs and the programs of our NAV Technology Licensees, will enable us and our partners to develop best-in-class gene therapy candidates for a wide range of disease targets due to these unique properties.
