%description
Plan optimal sample size allocation and go/no-go decision rules for phase
II/III drug development programs with time-to-event, binary or normally
distributed endpoints when assuming fixed treatment effects or a prior
distribution for the treatment effect, using methods from Kirchner et al.
(2016) <doi:10.1002/sim.6624> and Preussler (2020). Optimal is in the
sense of maximal expected utility, where the utility is a function taking
into account the expected cost and benefit of the program. It is possible
to extend to more complex settings with bias correction (Preussler S et
al. (2020) <doi:10.1186/s12874-020-01093-w>), multiple phase III trials
(Preussler et al. (2019) <doi:10.1002/bimj.201700241>), multi-arm trials
(Preussler et al. (2019) <doi:10.1080/19466315.2019.1702092>), and
multiple endpoints (Kieser et al. (2018) <doi:10.1002/pst.1861>).
