Abstract

Two decades of research on RNA interference (RNAi) have transformed a breakthrough discovery in biology into a robust platform for a new class of medicines that modulate mRNA expression. Here we provide an overview of the trajectory of small-interfering RNA (siRNA) drug development, including the first approval in 2018 of a liver-targeted siRNA interference (RNAi) therapeutic in lipid nanoparticles and subsequent approvals of five more RNAi drugs, which used metabolically stable siRNAs combined with N-acetylgalactosamine ligands for conjugate-based liver delivery. We also consider the remaining challenges in the field, such as delivery to muscle, brain and other extrahepatic organs. Today's RNAi therapeutics exhibit high specificity, potency and durability, and are transitioning from applications in rare diseases to widespread, chronic conditions.

摘要

二十年来对RNA干扰(RNAi)的研究已将一项生物学上的突破性发现转化为一个强大的平台,用于开发一类调节mRNA表达的新型药物。在此,我们概述了小干扰RNA(siRNA)药物的研发历程,包括2018年脂质纳米颗粒包裹的肝脏靶向性siRNA干扰(RNAi)疗法首次获批,以及随后另外五种RNAi药物的获批,这些药物使用了代谢稳定的siRNAs并结合N - 乙酰半乳糖胺配体用于基于偶联物的肝脏递送。我们还探讨了该领域尚存的挑战,比如向肌肉、大脑和其他肝外器官的递送。如今的RNAi疗法具有高特异性、高效力和持久性,正从罕见病应用向广泛的慢性病应用转变。
