Produktbeschreibung

This book provides a comprehensive, up-to-date, and practical introduction to the estimand framework and its application in clinical trials. Since its introduction by the International Council for Harmonisation (ICH) through the E9(R1) guideline in 2019, the estimand framework has led to a significant shift in the design, conduct, analysis, and interpretation of clinical trials. By explicitly aligning trial objectives with the clinical question of interest and by carefully accounting for intercurrent events the framework facilitates greater transparency and interpretability of trial results. In recent years, its adoption has supported improved scientific and regulatory dialogue, more targeted trial designs and analysis methods, and a better understanding of treatment effects across drug development programs.

This book reflects both the conceptual underpinnings of the estimand framework and the growing body of experience gained by the scientific and regulatory communitysince the release of the ICH E9(R1) guideline. Emphasis is placed on practical implementation across a wide range of clinical and therapeutic settings.

· Part I introduces the core concepts of the framework and offers detailed guidance on how to describe estimands in clinical trial protocols and related documents.

· Part II presents a wide range of case studies from various therapeutic areas to support practical implementation.

· Part III summarizes estimand-related content from regulatory guidelines across dif
