Adverum Biotechnologies, Inc. is a clinical-stage gene therapy company. It discovers and develops gene therapy product candidates that provide durable efficacy by inducing sustained expression of a therapeutic protein. Its lead product candidate, ixoberogene soroparvovec (Ixo-vec), is a single, in-office intravitreal (IVT) injection gene therapy product designed to deliver long-term durable therapeutic levels of aflibercept associated with a sustained treatment response, reducing the treatment burden and fluctuations in macular fluid associated with bolus anti-vascular endothelial growth factor (VEGF) IVT injections. Ixo-vec is being developed for the treatment of patients with wet age-related macular degeneration (wet AMD). Its other partnered programs include BGTF-027 (AAV.7m8-L-opsin), a gene therapy product candidate designed to deliver a functional copy of the OPN1LW gene to the foveal cones of patients suffering from blue cone monochromacy (BCM) via a single IVT injection.
