This forum will review best practices for quantifying a meaningful change in a patient-reported outcome (PRO) endpoint and establishing a responder definition in the presence of missing score data. Missing data strategies that do not assume absence of a PRO score means “non-responder.”

Learning Objectives

Recognize problems in responder analyses if subjects discontinue study treatment or withdraw from a trial; Compare approaches published by EMA, NAS, and in the ICH E9(R1): Addendum to Statistical Principles for Clinical Trials on Choosing Appropriate Estimands and Defining Sensitivity Analyses in Clinical Trials; Recognize how to combine multiple missing data approaches to tell the data story.
