A Statistical Framework for Decision Making in Confirmatory Multipopulation Tailoring Clinical Trials

Abstract

This article focuses on statistical analysis of clinical trials pursuing tailored therapy objectives, wherein evaluation of treatment effect occurs in the overall population as well as in a predefined subpopulation(s). The design and analysis principles presented provide a framework for decision making based on these novel multipopulation tailoring trial designs, considering the particular case of confirmatory trials. These principles include traditional multiple testing considerations, as well as 2 new analysis principles.
