  Platform trials have gained a lot of attention recently as a possible remedy
for time-consuming classical two-arm randomized controlled trials, especially
in early phase drug development. This short article illustrates how to use the
CohortPlat R package to simulate a cohort platform trial, where each cohort
consists of a combination treatment and the respective monotherapies and
standard-of-care. The endpoint is always assumed to be binary. The package
offers extensive flexibility with respect to both platform trial trajectories,
as well as treatment effect scenarios and decision rules. As a special feature,
the package provides a designated function for running multiple such
simulations efficiently in parallel and saving the results in a concise manner.
Many illustrations of code usage are provided.
