Objective

With the release of guidance for adaptive design in clinical trials both domestically and internationally, designing interim analyses in clinical trials has great guiding significance for the success of clinical trials. It not only helps to improve research and development efficiency, but also has important preventive significance for clinical trials that have chosen incorrect statistical methods, resulting in serious issues such as type I error inflation and introduction of bias, which may lead to the failure of clinical trials. This article combines three cases that have occurred in current clinical trials to analyze and summarize the statistical issues related to confirmatory clinical trial interim analyses, promoting a deeper understanding of interim analyses and providing references for the high-quality design, implementation, analysis, and interpretation of results of confirmatory clinical trials..

随着国内外临床试验适应性设计指导原则的发布,在临床试验中设计期中分析,对临床试验的成功与否,具有很大的指导意义,它不但有助于提高研发效率,而且,对一些临床试验选择了不正确的统计方法,从而导致I类错误膨胀、引入偏倚等严重问题,可能引起临床试验失败有重要防范意义。本文结合目前临床试验中出现的3个案例,对确证性临床试验期中分析相关统计学问题进行了分析与总结,促进了对期中分析的深入理解,为确证性临床试验进行高质量地设计、实施、分析和结果解释提供参考。

随着国内外临床试验适应性设计指导原则的发布,在临床试验中设计期中分析,对临床试验的成功与否,具有很大的指导意义,它不但有助于提高研发效率,而且,对一些临床试验选择了不正确的统计方法,从而导致I类错误膨胀、引入偏倚等严重问题,可能引起临床试验失败有重要防范意义。本文结合目前临床试验中出现的3个案例,对确证性临床试验期中分析相关统计学问题进行了分析与总结,促进了对期中分析的深入理解,为确证性临床试验进行高质量地设计、实施、分析和结果解释提供参考。

Objective

With the release of guidance for adaptive design in clinical trials both domestically and internationally, designing interim analyses in clinical trials has great guiding significance for the success of clinical trials. It not only helps to improve research and development efficiency, but also has important preventive significance for clinical trials that have chosen incorrect statistical methods, resulting in serious issues such as type I error inflation and introduction of bias, which may lead to the failure of clinical trials. This article combines three cases that have occurred in current clinical trials to analyze and summarize the statistical issues related to confirmatory clinical trial interim analyses, promoting a deeper understanding of interim analyses and providing references for the high-quality design, implementation, analysis, and interpretation of results of confirmatory clinical trials..
