摘要:

文题释义:

ClinicalTrials.gov注册平台:ClinicalTrials.gov注册平台现由美国国立卫生研究院(National Institutes of Health,NIH)国家医学图书馆(National Library of Medicine,NLM)维护,是国际上使用最普遍的临床试验注册平台,涵盖了美国50个州和另外208个国家/地区开展的多个领域的近30万项临床试验;此外,在该平台进行临床试验注册符合国际医学期刊编辑委员会(International Committee of Medical Journal Editors,ICMJE)对相关论文发表的要求。

对组织工程临床转化研究的意义:基于ClinicalTrials.gov注册平台中的临床试验注册数据,通过对组织工程领域临床试验的注册数量、适应证、申办者、分期等角度进行统计分析,全面把握该领域的临床试验注册现状,以期为组织工程临床转化研究提供参考和证据支持。

背景:组织器官市场供求不平衡,积极开展组织工程基础研究并加快临床转化至关重要。

目的:对组织工程临床试验注册现状进行整体分析,为组织工程临床转化研究提供参考和证据支持。

方法:通过ClinicalTrials.gov注册平台采集数据,利用文献计量法和数理统计法,从注册数量、适应证、申办者、分期等角度对组织工程临床试验注册现状进行分析。

结果与结论:①全球组织工程领域临床试验434项,中国65项;全球和中国均是超过一半为随机对照试验,全球18项国际多中心临床试验中未见中国机构参与;全球和中国分别涵盖适应证57种、37种,主要集中于骨和软骨、牙、皮肤等领域;全球申办者275个,中国33个;②全球和中国均是Ⅰ期/Ⅱ期临床试验注册数量最多;③通过对组织工程临床试验注册现状的分析发现,组织工程领域的临床应用转化较少,中国虽然注册数量在全球占据第二位,但与美国仍存在一定差距;已经积累了一定数量的高证据级别的临床试验,但缺乏高潜在国际市场价值的产品;研究机构和医疗机构对临床转化研究更为重视,临床应用主要集中于骨和软骨、牙及皮肤的缺损或功能缺陷的治疗,主要处于安全性或有效性评价阶段。

Abstract:

BACKGROUND: There is an imbalance between supply and demand for tissues and organs. Therefore, it is crucial to actively carry out basic research regarding tissue engineering and accelerate relevant clinical transformation.

OBJECTIVE: To analyze the status of clinical trials registrations in tissue engineering and to provide reference and evidence support for clinical transformation research in tissue engineering.

METHODS: Clinical trial data from the ClinicalTrials.gov were collected. Bibliometrics and mathematical statistics methods were adopted to analyze the status of clinical trial registration in tissue engineering from various aspects, including registration quantities, indications, sponsors, and stages.

RESULTS AND CONCLUSION: There were 434 records of clinical trial registrations regarding tissue engineering worldwide, 65 of which were in China. Over half of the records were randomized controlled trials in China or in the world, and no Chinese institutions have participated in the 18 international multi-center clinical trials worldwide. These clinical trials covered a total of 57 indications all over the world and 37 indications in China, mainly concentrated in the fields of bone and cartilage, teeth, and skin. There were 275 sponsors all over the world, 33 of which were in China. Most of the clinical trials were in phase 1/phase 2. Through analyzing the status of clinical trial registrations regarding tissue engineering, there were less clinical transformation applications in tissue engineering. Although China had the second largest number of registrations in the world, there was still a certain gap with the United States. There were a certain number of clinical trials with high evidence levels, but no products with high potential value in the international market. More concerns were paid onto clinical transformation research in research institutions and medical institutions. Clinical applications mainly focused on the treatment of defects or functional defects in bone and cartilage, teeth and skin, which were mainly in the stage of safety or efficacy evaluation.
