Stata command for calculating adverse event and efficacy stopping boundaries for phase II single-arm trials

Many programs and functions in statistical packages focus on the final stage of clinical trials, that is, the data analysis. In this article, I aim to assist in the early stages of clinical trials, specifically, the design of phase II single-arm trials. I present the new command stopbound, which calculates stopping boundaries and operating characteristics based on monitoring an adverse event, efficacy, or an adverse event and efficacy.
