Establishment of RWS guidance reflecting contributions of China to regulatory science

Abstract

ABSTRACT China’s accession to the ICH has accelerated the advancement of its regulatory science. To foster innovation and improve the efficiency of pharmaceutical research and development, the China National Medical Products Administration (NMPA) encourages the use of real-world evidence (RWE) to support drug regulatory decision-making and has constructed a series of real-world study (RWS) related guidance, reflecting the contribution of the NMPA to the field of RWS in drug clinical development. Based on the four guidelines on RWE, real-world data (RWD), RWS design and protocol development, and communication with regulatory authorities, the guidance has been extended to more specific clinical applications, such as oncology, rare diseases, pediatric drugs, and traditional Chinese medicine. This paper reviews the core content and features of the series of RWS guidelines, presents their role in promoting drug development, and discusses challenges of using RWE in support of drug regulatory decision-making in China.
