drugdevelopR | R Documentation |
The drugdevelopR package enables utility based planning of phase II/III drug development programs with optimal sample size allocation and go/no-go decision rules. The assumed true treatment effects can be assumed fixed (planning is then also possible via user friendly R Shiny App: drugdevelopR) or modelled by a prior distribution. The R Shiny application prior visualizes the prior distributions used in this package. Fast computing is enabled by parallel programming.
drugdevelopR()
The drugdevelopR package provides the functions to plan optimal phase II/III drug development programs with
time-to-event endpoint (optimal_tte
),
binary endpoint (optimal_binary
) and
normally distributed endpoint (optimal_normal
),
where the treatment effect is assumed fixed or modelled by a prior. In these settings, optimal phase II/III drug development planning with fixed assumed treatment effects can also be done with the help of the R Shiny application basic. Extensions to the basic setting are
optimal planning of programs including methods for discounting of phase II results (function: optimal_bias
, App: bias),
optimal planning of programs with several phase III trials (function: optimal_multitrial
, App: multitrial) and
optimal planning of programs with multiple arms (function: optimal_multiarm
, App: multiarm).
The R Shiny App drugdevelopR serves as homepage, navigating the different parts of drugdevelopR via links.
