It is well known that the standard single-stage binomial test is uniformly most powerful to detect an increase or decrease in a binomial proportion. The general perception is that, to achieve a ΓΏxed signiΓΏcance level and power, a group sequential test will require a larger maximum total sample size
We developed an interactive and menu-driven computer program to help investigators design and analyze phase II cancer clinical trials with a group sequential method, namely the sequential probability ratio test or the triangular test. Based on the values selected for the parameters of the trial, the
