Evidence produced by clinical trial is the main basis for health care decision-making at all levels. In recent years, some problems been revealed in the national data audit of new drug clinical trials have sounded the alarm for the quality of clinical research in China. In addition to strengthening the implementation of clinical trial process management and supervision, we call attention to the coherence and consistency of trial design and implementation, including the promotion of clinical trial design in the agenda of improving the quality of the trials and putting forward reasonable suggestions. We hope that our work could make research ideas clear from the source of a clinical trial, with a view to avoid violating protocol behavior and provide standardized recommendations for improving the quality of clinical trials in China.
Clinical trials are the most reliable means for scientifically rigorous evaluation of the efficacy and safety of drugs, and are the most crucial part receiving the most investment in development and innovation in the pharmaceutical industry. In recent years, the nation has formulated a set of policies and guiding principles to encourage pharmaceutical innovation, promote the independent innovation of China’s pharmaceutical industry and enhance clinical trial capacity. To further improve Chinese researchers’ ability to perform clinical trials, the National Clinical Research Center for Cardiovascular Diseases, Fuwai Hospital, Chinese Academy of Medical Sciences and the National Center for Cardiovascular Diseases invited a multi-disciplinary team of experts from various areas including clinical trial methodology and supervision to work on this consensus. In view of the common concern and puzzles regarding the issues in clinical trials, such as recruitment and retention of participants, outcome selection, quality control, information technology application, and ethics in data security, the expert consensus is based on domestic and international guidelines, the latest advancement of clinical research, and the advice and opinions from national experts. It aims to provide reference information and guidance for clinical trial researchers, and serves as a reference for relevant authorities to formulate clinical trial management policies.
The modern clinical research evaluation system has been increasingly emphasizing the evaluation of individual patients' clinical characteristics, diagnosis and treatment plans, and complex intervention measures. Traditional randomized controlled trial evaluated fixed interventions and non-adaptive treatment plans, which cannot meet the needs of evaluating adaptive interventions. This made researchers more inclined to explore an individualized and adaptive clinical trial design, then sequential multiple assignment randomized trial (SMART) emerged as the time needed. This article introduces the principles, key elements, and implementation points of SMART design, further explores the limitations of the mismatch between traditional Chinese medicine clinical trial design and syndrome differentiation treatment, and proposes that SMART design can meet the needs of traditional Chinese medicine clinical trials to inspire researchers in designing their plans.
