In an era of rapid scientific advancement, gene therapy has emerged as a groundbreaking approach with the potential to revolutionize the treatment of a myriad of diseases and medical conditions. The trend of current clinical trials suggests that there is growing interest and investment in exploring gene therapy as a viable treatment option. In 2023, a significant milestone was achieved with the approval of seven gene therapies by the Food and Drug Administration (FDA). Projections indicate that between 10 and 20 gene therapies could receive annual FDA approval by 2025. In this review, we conducted a comprehensive analysis of registered clinical trials on Clinicaltrials.gov to determine the progression status of gene therapies. Upon extraction of the data, we conducted a comprehensive analysis of the 2809 included studies. This involved a systematic approach, commencing with an overview, followed by a detailed examination of gene therapy strategies employed in various malignant and non-malignant disorders. Additionally, the study will cover the types of vectors utilized in current trials. Lastly, a meticulous review of 105 phase III-IV clinical trials was conducted to identify potential therapies demonstrating promise. We trust that the comprehensive overview provided will serve as a solid foundation for forthcoming research and study designs, ultimately contributing to the progression of gene therapy and its practical application within healthcare settings. Also, we anticipate that such inquiries will bolster the formulation of practical policies and guidelines for pharmaceutical companies engaged in gene therapy research and development.
