OBJECTIVE： To summarize the problems and countermeasures which the construction of drug clinical trial institutions face after China Food and Drug Administration （CFDA） join in ICH， and its effects on clinical study management in China. METHODS： Combined with the experience on Good Clinical Practice （GCP） in our hospital during recent years， reviewing related content of ICH-GCP， the differences between China’s GCP （CFDA-GCP） and ICH-GCP， the problems faced by drug clinical trial institutions after joining in ICH， and the thinking of China’s clinical research were discussed. RESULTS & CONCLUSIONS： There were differences between CFDA-GCP and ICH-GCP in the management concept of clinical drug trials， the structure and function of ethical committees， the protection of the rights and interests of subjects， the choice of researchers and research institutions， management requirements of experimental drugs and the management of documents and data. After joining in ICH， the current organization and management structure， system and standard operating procedures， ethics committee， GCP training and continuing education， professional quality control system， experimental drug management， data management and information system construction and upgrading， clinical research coordinator management and other aspects of the drug clinical trial institutions were far from the requirements of ICH. The standardization of drug clinical trial institutions in China can be further promoted by revising regulations and guidelines， formulating standard operating procedures in line with ICH-GCP， building standardized ethics committees， implementing GCP training and continuing education， improving quality control system and drug management in clinical trials， strengthening hardware and software construction and clinical coordinator management， etc. At the same time， problems such as fewer full-time personnel and weak implementation of the system can be improved by strengthening project management， improving the quality of employees and building normal cross-regional cooperation.
