TITLE: Overview Of Non-Inferiority Trial Design, Analysis and Reporting

SPEAKER: Susan Wang, Boehringer Ingelheim, China.
Gang Cheng, Boehringer Ingelheim, China.



The standard method for evaluating the efficacy of a new treatment is via conducting a placebo controlled superiority trial. However, a non-inferiority (NI) trial is considered when the use of a placebo arm is not ethnical or not feasible. The design, conduct, analysis and interpretation of a NI trial are more challenging than that of a superiority trial. With its increased applications in more and more disease areas in the drug development, a clear understanding of all aspects of a NI trial is crucial to the success of the trial. This short course is designed to give the audience a comprehensive understanding of the NI concept, the methods and considerations of its design, and its applications in various disease areas. The fixed margin approach, the synthesis method and the Bayesian method will be discussed for designing a NI trial. Real world examples are used to demonstrate the selection and calculation of the M1 and M2 margins when the fixed margin approach is used. Case studies involving Bayesian approaches are also included.

Many factors may impact the design, the analysis, and the interpretations of the results, such as assay sensitivity, constancy assumptions, and quality of current and historical trials. These will be discussed thoroughly in the presentation.
