The aim of single-arm clinical trials of a new drug is to determine whether it has sufficient promising activity to warrant its further development. For the last several years Bayesian statistical methods have been proposed and used. Bayesian approaches are ideal for earlier phase exploratory trials or proof-of-concept studies as they take into account information that accrues during a trial. Posterior and predictive probabilities are then updated and so become more accurate as the trial progresses. If the relevant external information is available, the decision will be made with a smaller sample size. The goal of this paper is to provide a review for statisticians who use Bayesian methods for the first time or investigators who have some statistical background. In addition, a clinical trial is presented as a real example to illustrate how to conduct a Bayesian approach for single-arm clinical trials with binary endpoints.

希少疾患が対象の試験ではコントロールを設定することが困難なことがあります。そこで,実薬群のみの試験という状況が結構想定されます。そんなときに私がよく参考にするのが手良向先生の論文です
【臨床試験:ベイズ流階層モデル】 私はベイズ統計の専門家では無く、あまり解説できません。多分統計たん( @stattan)の方がご専門。日本語の総説ではこれが一番だと思うわ。 https://t.co/HcLtxdZsFP
