遗传毒性研究是药物非临床安全性评价的重要内容,与致癌性、生殖毒性研究密切相关.遗传毒性试验目的是检测受试物的致突变性,预测受试物的致癌性,对受试物的遗传毒性潜在性进行全面评价是药物进入临床试验及上市的重要环节.遗传毒性标准试验组合包含体内和体外试验,测试终点多样,本文从人员资质、实验室管理、给药制剂、实验系统、试验实施关键阶段等方面阐述遗传毒性评价研究的关注点,为遗传毒性研究实施提供借鉴.研究机构应严格遵循药物非临床研究质量管理规范(good laboratory practice for nonclinical laboratory studies,GLP)实施评价工作,不断提高遗传毒性试验质量.
Concerns of the genotoxicity evaluation of drugs
Genotoxicity evaluation is an important part of the non-clinical safety evaluation of drugs,which is closely related to carcinogenicity and reproductive toxicity.The purpose of genotoxicity test is to detect the mutagenicity and potential carcinogenic effects of the test articles,and a comprehensive assessment of their genotoxicity potential is an important link for drugs to enter clinical trials and marketing.The standard test battery for genotoxicity includes in vivo and in vitro tests with a variety of endpoints.In this paper,the concerns of genotoxicity evaluation were expounded from the personnel qualification,laboratory management,dose formulation,test system,key stages of experimental implementation,etc.,so as to provide reference for the conducting of genotoxicity study.The safety assessment should be conducted in strict compliance with the good laboratory practice for nonclinical laboratory studies(GLP)by the testing facility,and the quality of genotoxicity tests should be improved constantly.
