The study examines the issue of drug lag in China, emphasizing the importance of reducing the clinical trial starting time over shortening development and review times. Efforts to cut regulatory processes should focus on defining clinical value, regulatory procedure harmonization, and fostering discussions between applicants and regulators. Enhancing domestic research and development capabilities remains crucial for reducing drug lag, and regulatory agencies should focus on accumulating experience with innovative drugs and changing the regulatory approach to generics.
China has been criticized for the long drug delay for a long time. There was little understanding of Chinese drug lag formation from the investigational new drug (IND) submission to the new drug application (NDA) approval. Therefore, we analyzed the problem of drug lag in China cumulating from the clinical trial starting lag to the lags formed during the regulatory process and discerned the key underlying factors. After investigating the availability in China of new molecular entities (NMEs) approved by the Food and Drug Administration (FDA) between 1999 and 2019, we find that even though cutting regulatory process could reduce the approval lag, the clinical trial starting time in China is more important in drug lag reduction than shortening development time and review time. The reduction of the regulatory process also needs continuous efforts by defining the clinical value based on the medical needs, regulatory procedure harmonization, and intensive discussions between applicants and regulators during the drug development process. Meanwhile, proactive approaches should be taken to encourage developing the first generics in China. More importantly, enhancing domestic research and development capabilities is still the key to cutting the drug lag. Moreover, the China National Medical Product Administration (NMPA) should attach importance to the accumulation of regulation experience on innovative drugs and transform the style of regulating generics to new drugs.
