[Current status of registered drug and vaccine pediatric clinical trials in China].

Abstract

Objective: To evaluate the current status of the registered pediatric drug or vaccine clinical trials in China for the purpose of providing a reference for the development of pediatric clinical trials in China. Methods: We collected the data about registered pediatric clinical trials that were conducted from September 6, 2013(Mandatory registration start date) to September 6, 2019 (Cut-off date) at Chinadrugtrials.org.cn platform. The survey items included trial name and number, drug classification, sponsor's information, current trial status, completion status, etc. The clinical trials were categorized by drug group (includes chemical medicine, traditional Chinese medicine and natural medicine, biological products) and by vaccine group. Results: During the six years 349 pediatric clinical trials were registered on the platform, including 162 pediatric drug trials and 187 vaccine trials. The numbers of chemical drugs and biological products registered in 2018 were 23 and 11, respectively, the highest in the history. The number of pediatric clinical trials of traditional Chinese medicine and natural medicine was 11 in 2014, but from 2015 to 2018 only 2 to 4 trials were registered each year. The overall completion rates of the registered drug and vaccine clinical trials were 22.8% (37/162) and 41.7%(78/187), respectively. Only 42 international multicenter pediatric clinical trial projects were registered on the platform. The numbers of drug and vaccine phase Ⅰ clinical trials were 4 and 46, respectively. Thirty-six pediatric endocrine system agent clinical trials were carried out, with the largest number of all the drug categories registered on the platform. Conclusions: In recent years the number of registered pediatric drug and vaccine clinical trials increased in China. However, the number is still very limited. It is urgent to further promote the development of pediatric clinical trials.
