StrideBio's AAV vector development platform uses structure-guided evolution to discover novel capsids with a reduced antibody binding profile in multiple tissues, including: liver, muscle, eye and central nervous system, with improved properties for in vivo gene delivery applications. The underlying technology is based on the work of co-founders, Dr. Aravind Asokan at the University of North Carolina at Chapel Hill and Dr. Mavis Agbandje-McKenna at the University of Florida.

"Stride is built on our deep understanding of AAV biology and structure to develop novel and differentiated AAV capsids to overcome performance challenges faced by this vector system," said Dr. Agbandje-McKenna. "We believe our innovative platform will create vectors that substantially impact the way devastating rare diseases are treated and we look forward to working with our new investors to achieve this important goal."
