本文考虑了使用临床医生和患者报告的结果来设计 I 期临床试验的概念,以适应性地将研究参与者分配到可耐受剂量,并在研究结论时确定最大耐受剂量 (MTD)。我们描述了贝叶斯形式的患者报告结果持续重新评估方法 (PRO-CRMB) 在子宫内膜癌辅助大分割全骨盆放射治疗 (WPRT) 的 I 期研究 (NCT04458402) 中的应用。该研究的主要目标是确定 WPRT 每个部分的 MTD,由可接受的临床医生和患者报告的 DLT 率定义。我们对设计的操作特性进行模拟研究,并将其与基于规则的方法进行比较。我们说明 PRO-CRMB 在研究期间进行适当的剂量分配,以使研究人员和审稿人了解该方法的行为方式。在模拟研究中,PRO-CRMB 在推荐目标治疗课程和将患者分配到这些课程方面表现出优于 5 + 2 逐步设计的性能。该设计配有易于使用的 R闪亮网络应用程序,可在设计阶段模拟操作特征,并在整个试验过程中按顺序更新剂量分配。
This article considers the concept of designing Phase I clinical trials using both clinician- and patient-reported outcomes to adaptively allocate study participants to tolerable doses and determine the maximum tolerated dose (MTD) at the study conclusion. We describe an application of a Bayesian form of the patient-reported outcomes continual reassessment method (PRO-CRMB) in an ongoing Phase I study of adjuvant hypofractionated whole pelvis radiation therapy (WPRT) in endometrial cancer (NCT04458402). The study’s primary objective is to determine the MTD per fraction of WPRT, defined by acceptable clinician- and patient-reported DLT rates. We conduct simulation studies of the operating characteristics of the design and compared them to a rule-based approach. We illustrate that the PRO-CRMB makes appropriate dose assignments during the study to give investigators and reviewers an idea of how the method behaves. In simulation studies, the PRO-CRMB demonstrates superior performance to a 5 + 2 stepwise design in terms of recommending target treatment courses and allocating patients to these courses. The design is accompanied by an easy-to-use R shiny web application to simulate operating characteristics at the design stage and sequentially update dose assignments throughout the trial’s conduct.
