Abstract

Gene therapies are innovative treatments that could revolutionize healthcare. Given their unique mechanisms of action, methods of manufacturing and administration, and the potential for long-lasting impact, gene therapies require long-term follow-up (LTFU) of safety and effectiveness post authorization, often using real-world data (RWD). With over 2000 gene therapies in development, there is a need for knowledge-building regarding LTFU studies. Here, we review regulatory, scientific, and operational requirements and considerations for LTFU studies using RWD from a global perspective. The insights in this review support post-authorization LTFU studies for gene therapies, thereby contributing to their safe and effective use.
