The Direct Assignment Option as a Modular Design Component: An Example for the Setting of Two Predefined Subgroups
Background. A phase II design with an option for direct assignment (stop randomization and assign all patients to experimental treatment based on interim analysis, IA) for a predefined subgroup was previously proposed. Here, we illustrate the modularity of the direct assignment option by applying it...
