Gene therapy research in Asia

Gene therapy has shown great potential for the treatment of diseases that previously were either untreatable or treatable but not curable with conventional schemes. Recent progress in clinical gene therapy trials has emerged in various severe diseases, including primary immunodeficiencies, leukodystrophies, Leber's congenital amaurosis, haemophilia, as well as retinal dystrophy. The clinical transformation and industrialization of gene therapy in Asia have been remarkable and continue making steady progress. A total of six gene therapy-based products have been approved worldwide, including two drugs from Asia. This review aims to highlight recent progress in gene therapy clinical trials and discuss the prospects for the future in China and wider Asia.
