Outline
The diversity of clinical trial population is the key to ensure the generalizability of drug safety and efficacy assessment results obtained from clinical trials, and plays an important role in advancing research on new drugs and strengthening the regulation of marketed drugs to improve the quality of life for patients. The United States has accumulated rich experience in improving the diversity of clinical trial population. Regulatory authorities have established a policy system for improving research practice, reducing patient participation barriers, and promoting data collection and sharing, and have provided diversified clinical trial information to the public. Clinical trial institutions have promoted the participation of patients from different backgrounds in clinical trials by strengthening inter-agency cooperation, facilitating community involvement, and improving the cultural inclusiveness of employees. China can learn from the relevant experience of the United States, improve the supervision system of clinical trial population diversity, promote the capacity building of clinical trial institutions to serve diverse populations, and strengthen the publicity and education of clinical trials, so as to improve the diversity of clinical trial population.
