%description
Bayesian optimal design with futility and efficacy stopping boundaries
(BOP2-FE) is a novel statistical framework for single-arm Phase II
clinical trials. It enables early termination for efficacy when interim
data are promising, while explicitly controlling Type I and Type II error
rates. The design supports a variety of endpoint structures, including
single binary endpoints, nested endpoints, co-primary endpoints, and joint
monitoring of efficacy and toxicity. The package provides tools for
enumerating stopping boundaries prior to trial initiation and for
conducting simulation studies to evaluate the design’s operating
characteristics. Users can flexibly specify design parameters to suit
their specific applications. For methodological details, refer to Xu et
al. (2025) <doi:10.1080/10543406.2025.2558142>.
