Considerations on Clinical Development and Regulatory of the Oversea License-in Anti-tumor Drugs / 中国肺癌杂志

With the boom of China's innovative pharmaceutical industry, licensing-in model has gradually become an important research and development model for innovative pharmaceutical companies. The in-licensed drugs at different stages need different research and development (R&D) strategy in China. The pharmaceutical companies take the responsibility to comprehensively collate the oversea clinical data and conduct a detailed analysis of clinical pharmacology, safety, efficacy and ethnic sensitivity. Clinical R&D strategy should be made based on the results of the above data and analysis. We encourage high-quality drugs which fill unmet clinical needs licensed in, and as early as possible, so as to conduct multi-regional clinical trials (MRCTs). The clinical R&D strategy in China is particularly important for the drug's approval. Guidelines published by the National Medical Products Administration (NMPA) and clinical associations should be followed. Communications about clinical R&D strategy with Center of Drug Evaluation (CDE) are encouraged.

Bridging studies in clinical trials for new drug application / 中国临床药理学与治疗学

AIM:To introduce the concept of bridging study and its strategies in clinical trials for new drug application.METHODS:The concept of bridging study proposed in the ICH E5 guideline was introduced,with a case using bridging strategies in the new drug applications(NDAs)approved by the regulatory authority in Japan.The concrete mode and the development of bridging studies in Asia were summarized.RESULTS:With the application of the ICH E5,some countries and regions have successfully used the bridging strategy in the new drug applications.The bridging strategy is becoming a common and practical basis for the decision making of marketing approvals of new drugs in the Asia-pacific country.CONCLUSION:The currently bridging studies in Asia will play an important role in the extrapolation of foreign clinical data in new drug application.Using bridging study is very helpful in judging ethnic differences of drugs,reducing duplication of clinical trails,as well as shortening clinical development periods.
