Regulations and safety assessment of genome editing technologies for human gene therapy

2020 Translational and Regulatory Sciences  
Genome editing technologies, including clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein 9 (Cas9) system, are expected to become a state-of-the-art strategy for human gene therapy. However, there are several new safety issues to be addressed before clinical use. This review article summarizes the current regulatory status of the safety assessment of genome editing for human gene therapy. In addition, with a focus on unintended genome editing by
