摘要
由于具有在伦理道德、有效性和灵活性等方面的优势,自适应设计在临床试验中受到越来越广泛的关注。本文首先介绍了两类主要的自适应设计,随机化罐子模型和基于序贯估计的方法。随后,本文着重介绍了自适应设计的近期进展:(1)自适应设计中的序贯监测问题;(2)自适应设计在响应变量为生存数据、复发事件数据和有序数据的试验中,以及在非劣效试验中的应用。最后我们探讨了自适应设计中尚需进一步解决的问题以及今后可能的研究方向。
Because of its three advantages:Ethical,efficient and flexible,response-adaptive randomization(RAR)has recently attracted a great deal of attention in clinical research.In this paper,we first introduce two main types of RAR,namely,randomized urn models and the sequential-estimation model.Then we focus on the recent advances of RAR in the literature:(i)sequential monitoring of clinical trials based on RAR;and(ii)the applications of RAR for survival data,recurrent event data,and ordinal data and in non-inferiority trials.Lastly,we discuss a few unsolved issues and suggest some future research directions.
