Over 180 companies are actively developing more than 250 AAV-based gene therapies, representing a robust pipeline for treating genetic disorders including hemophilia, spinal muscular atrophy, and inherited retinal diseases.
Recent FDA approvals include Roctavian for severe hemophilia A and Elevidys for Duchenne muscular dystrophy, demonstrating the therapeutic potential of AAV vectors in addressing rare genetic conditions.
The field has experienced notable setbacks, including Pfizer's termination of its hemophilia A partnership and a patient death linked to Elevidys treatment, highlighting ongoing safety challenges.
Leading pipeline candidates include DTX401 for glycogen storage disease, SRP-9003 for limb-girdle muscular dystrophy, and several innovative therapies targeting retinal diseases and cardiovascular conditions.
