The phase 3 development program for ixoberogene soroparvovec (ixo-vec; Adverum Biotechnologies) in neovascular age-related macular degeneration (nAMD) is moving forward, according to Deepak Sambhara, MD, FASRS, who presented an overview of the program at the 2026 Retina World Congress. Ixo-vec is designed as a clinic-based intravitreal gene therapy using an AAV7m8 vector engineered to cross the internal limiting membrane and transduce retinal cells.
