Clinical endpoint committee (CEC) plays an important role in the process of the endpoint events adjudication in clinical trials. It greatly influences quality control of clinical trials, the importance of which increases especially after the emergency of the definition of clinical endpoint events by Academic Research Consortium (ARC). In this paper, we briefly introduce the role of CEC in the process of the quality control of clinical trials, application of CEC in China and abroad, and its influence to the primary endpoints. We also investigate the application and development of CEC in the field of cardiovascular diseases, and discuss how to reasonably apply CEC and maximize its role in the process of the endpoint events adjudication of clinical trials.
