Webb1 jan. 2002 · The optimal two-stage design was proposed by Simon. This method determines the adequate sample size by calculating the response probability of two groups with α and β errors [1, 2].... Webb20 maj 2024 · Optimal, minimax and admissible two-stage design for phase II oncology clinical trials Whenever (p0, p1) is pre-specified, it is better to explore in the range of probability q, based on relative importance between maximum sample size and expected sample size, and determine which design to choose.
WebbThe Simon two-stage optimal design is often used for phase II cancer clinical trials. A study proceeds to the second stage unless the null hypothesis, that the true tumour response rate is below some specified value, is already accepted at the end of stage one. Webbpaper presents two-stage designs that are optimal in the sense that the expected sample size is minimized if the regimen has low activity subject to constraints upon the size of …
