Simon optimal two stage design
WebbA robust two-stage design identifying the optimal biological dose for phase I/II clinical trials. Stat Med 36(1):27-42, 1/2024. e-Pub 8/2016. PMCID: PMC5138134. WebbThe Simon’s two-stage design to determine sample size is one that is widely used and accepted in Phase II cancer trials. A number of alternative methods that implement adaptive aspects to the design have also been published and used in trials.

Webbtwo-stage design that is optimal in the sense that the expected sample size is minimized if the regimen has low activity subject to constraints upon the size of the type 1 and type 2 errors. Two-stage designs which minimize the maximum sample size are also determined. simon2stage(p0, pa, alpha, beta, eps =0, N_min, N_max, int =0, WebbClassic two-stage hypothesis testing based designs such as a Simon two-stage optimal design can satisfy these requirements, when used in parallel for the multiple treatment arms. However, these can be inefficient and impractical in terms of the maximum planned sample size required for such a study.
