Outline

The online training course provides a detailed survey of advanced multiplicity problems with two or more sources of multiplicity in clinical trials (traditional problems with a single source of multiplicity are presented in Part I). Examples of advanced multiplicity problems include problems related to complex clinical objectives such as the evaluation of multiple endpoints at several dose levels or in several patient populations. Multiple testing procedures, known as gatekeeping procedures, used in confirmatory trials with complex objectives are presented. The course introduces popular methods for defining gatekeeping procedures, including a novel method based on the mixture approach, and describes their applications using case studies based on Phase III trials in multiple therapeutic areas. The course also discusses methods for handling multiplicity in group-sequential and general adaptive trials with multiple endpoints. Key regulatory considerations arising in the analysis and interpretation of complex clinical objectives, e.g., evaluation of secondary endpoints, in Phase III trials are presented with numerous references to the FDA and EMA multiplicity guidance documents released in 2017. A thorough discussion of software implementation issues using SAS and R software is provided in the course.
