AbstractThe methodological principles for the planning of interim analyses in a phase III clinical trial are presented in this article. The case for superiority, non-inferiority and futility, and the roles of Data Monitoring Committees are summarized. Several examples are presented to illustrate the methodology and to help investigators by better understanding and planning interim analyses in a phase III clinical trial.
