The design and analysis of cancer clinical trials with biomarker depend on various factors, such as the phase of trials, the type of biomarker, whether the used biomarker is validated or not, and the study objectives. In this article, we demonstrate the design and analysis of two Phase II cancer clinical trials, one with a predictive biomarker and the other with an imaging prognostic biomarker. Statistical testing methods and their sample size calculation methods are presented for each trial. We assume that the primary endpoint of these trials is a time to event variable, but this concept can be used for any type of endpoint.
使用生物标志物的癌症临床试验的设计与分析取决于多种因素,如试验阶段、生物标志物类型、所使用的生物标志物是否经过验证以及研究目标。在本文中,我们展示了两项II期癌症临床试验的设计与分析,一项使用预测性生物标志物,另一项使用成像预后生物标志物。针对每项试验给出了统计检验方法及其样本量计算方法。我们假定这些试验的主要终点是一个事件发生时间变量,但这一概念可用于任何类型的终点。
