The standard categorical system for assessing attribution of toxicity to study drug(s) in phase I trials is cumbersome and uninformative. Although a binary system ("related" vs. "unrelated") would be sufficient to define maximum tolerated dose (MTD), a probability estimation would better support dose selection for randomized dose-ranging phase II trials.
用于评估I期试验中研究药物毒性归因的标准分类系统既繁琐又缺乏信息量。虽然二元系统(“相关”与“不相关”)足以定义最大耐受剂量(MTD),但概率估计将更有助于支持随机剂量范围II期试验的剂量选择。
