Estimand Strategies in Early Phase Clinical Research

This case study presents estimand strategies in early phase clinical research, specifically focusing on Type 2 Diabetes. The document outlines how estimands provide a structured framework to define treatment effects by aligning study objectives with trial design, conduct, and analysis. It explains the introduction of estimands in the ICH E9(R1) addendum and their role in addressing complexities like intercurrent events, which occur after randomization or dosing. The case study details five estimand strategies, including Treatment Policy and Hypothetical, and discusses their applications in clinical trials. It emphasizes the importance of pre-defining trial objectives and desired outcomes, as well as the advantages and limitations of estimands in Phase I and II research. The document concludes by highlighting how estimand strategies enhance clarity and relevance in study outcomes, supporting informed decision-making in drug development.
