Efficacy endpoint selection and multiplicity adjustment methods in clinical trials with inherent multiple endpoint issues

Abstract
The ideal approach for the design and analysis of clinical trials is to select a single primary endpoint that provides a complete characterization of the disease under study and permits an efficient evaluation of the effect of a test drug. However, this is often not possible for a number of diseases or clinical trials. This paper examines some practical clinical decision‐making scenarios for the selection and analysis of efficacy outcome measures in clinical trials with inherent multiplicity components.
