RESUMEN
Progress in the understanding of human diseases has coincided with the advent of precision medicine, whereby the underlying genetic and molecular contributors can be used as diagnostic and therapeutic biomarkers. To address these, drug developers have designed a range of different treatment strategies, including gene therapy, which the American Society of Gene and Cell Therapy defines as the use of genetic material to treat or prevent disease. A number of approaches exist, including the delivery of genetic material in vivo or ex vivo, as well as the use of RNA species to alter gene expression in particular disease states. Through the end of the first quarter of 2023, there were more than 100 different approved gene, cell, and RNA therapies throughout the world, with over 3,700 more in clinical and preclinical development. This review comprehensively captures the landscape for such advanced therapies, including the different genetic technologies used and diseases targeted in clinical trials.
