Clinical trials of children's drugs are of great significance to rational drug use in children. However, paediatric drugs trials in China are facing complex challenges. At present, the investigation data on registration status of paediatric drug trials in China are still relatively lacking, and relevant research is urgently needed.
The advanced retrieval function is used to retrieve clinical trials data in the Clinical Trial.gov and Chinese Clinical Trial Registry databases in 22 April 2019. Fifteen key items were analysed to describe trial characteristics, including: registration number, study start date (year), mode of funding, type of disease, medicine type, research stage, research design, sample size, number of experimental groups, placebo group, blind method, implementation centre, child specific, newborn specific and participant age.
A total of 1388 clinical trials of paediatric drugs conducted in China were registered. The number of paediatric drug trials grew steadily over time, from less than 20 per year before 2005 to more than 100 per year after 2012. Most clinical trials were postmarketing (n=800, 57.6%), single-centre (n=1045, 75.3%), intervention studies (n=1161, 83.6%) without blinded methods (1169, 84.2%) and funded by non-profit organisations (n=838, 60.4%). The number of clinical trials for antineoplastic agents (n=254, 18.3%), anti-infectives (n=156, 11.2%) and vaccines (n=154, 11.1%) is the largest.
Paediatric drug trials in China made a significant progress in recent years. Innovative method and trial design optimisation should be encouraged to accelerate paediatric clinical research. Pharmaceutical companies need to be further stimulated to carry out more high-quality paediatric clinical trials with support of paediatric drug legislation.
儿童药物临床试验对儿童合理用药具有重要意义。然而,我国儿科药物试验面临着复杂的挑战。目前,我国儿科药物试验注册状态的调查数据仍相对匮乏,急需相关研究。
利用高级检索功能检索2019年4月22日Clinical Trial.gov和中国临床试验注册中心数据库中的临床试验数据。分析15个关键项目以描述试验特征,包括:注册号、研究开始日期(年份)、资助方式、疾病类型、药物类型、研究阶段、研究设计、样本量、实验组数量、安慰剂组、盲法、实施中心、儿童特定、新生儿特定和参与者年龄。
我国共注册了1388项儿科药物临床试验。儿科药物试验数量随时间稳步增长,从2005年前每年少于20项增至2012年后每年超过100项。大多数临床试验为上市后试验(n = 800,57.6%)、单中心试验(n = 1045,75.3%)、干预性研究(n = 1161,83.6%),无盲法(1169,84.2%),由非营利组织资助(n = 838,60.4%)。抗肿瘤药物(n = 254,18.3%)、抗感染药物(n = 156,11.2%)和疫苗(n = 154,11.1%)的临床试验数量最多。
近年来我国儿科药物试验取得了显著进展。应鼓励创新方法和优化试验设计以加速儿科临床研究。在儿科药物立法的支持下,需要进一步激励制药公司开展更多高质量的儿科临床试验。
