Abstract:

随机对照试验（RCT）被视为药械临床疗效评价的“金标准”。但针对罕见、重大且无有效治疗方式等疾病，考虑伦理、成本等因素，RCT并不适宜。此时，采用真实世界数据（RWD）作为试验的外部对照支持药械临床评价，可降低患者招募难度、缩减研发时间及成本。本文基于国内外最新发布的RWD有关的指导原则，并结合团队前期研究经验，介绍了采用RWD作为外部对照用于支持药械临床评价的常见应用场景、数据来源、研究设计、外部对照选择基本原则和统计分析方法，以期为相关学者、申办方开展RWD研究提供参考与借鉴。

English Abstract:

Randomized controlled trials (RCT) have long been considered the gold standard for assessing clinical efficacy. However, RCT are inappropriate for some diseases due to related ethical issues and costs, such as rare diseases that are seriously life-threatening but without adequate treatment. Using real world data (RWD) as external control for RCT could make recruitment less complicated and reduce time and cost. This paper introduces common application scenarios, data sources, study design, basic principles, and statistical methods of RWD as an external control based on the latest guidelines related to RWD and combined with our team's previous research experience. This study could provide references for scholars and sponsors who want to conduct RWD research.
