In confirmatory clinical trials, as often is the case, a single clinical outcome is selected as a primary endpoint. This endpoint serves as the basis for the trial design including sample size determination, interim data monitoring, final analyses and the reporting of the trial results. The primary endpoint is an outcome providing the most clinically relevant measure for the primary objective of a trial. However, a single primary endpoint often cannot provide comprehensive characterization about the important effects of the intervention as the diseases are caused by interdependent multiple factors such as genetic, environmental, lifestyle and other factors. For this reason, clinical trials may still be designed with either a single primary endpoint plus key secondary endpoints or more than one primary endpoint. Assessing multiple endpoints may offer an attractive design feature as they could capture multiple characteristics of the effects of an intervention and provide more informative intervention comparisons. However multiple endpoints also create challenges in design, interim monitoring, analysis and reporting of clinical trials. This short course will be devoted to discussion of some challenging statistical issues with multiple endpoints and statistical methods to meet the challenges. The outline of the short course includes:
- provide an overview of the concepts, principle and procedures for testing multiple endpoints
- discuss challenging problems with analysis of a single primary endpoint plus key secondary endpoints and more than one primary endpoint.
- review relevant regulatory guidelines and related documents
- integrate recent methodological developments for design, monitoring and analysis of clinical trials with multiple endpoints
- include case studies from actual clinical trials to help attendees quickly understand common methods and apply them to problems in real world.
- demonstrate how to implement the methods using statistical software, e.g., SAS and R

Dr. H.M. James Hung is Director of Division of Biometrics I (DBI), Office of Biostatistics, Office of Translational Sciences, Center for Drug Evaluation and Research (CDER), U.S. Food and Drug Administration (FDA). The Division provides statistical services for Division of Neurology Products, Division of Psychiatry Products, Division of Anesthesia, Analgesia, Addiction Products, and Division of Medical Imaging Products, CDER.
During his tenure with FDA, he had reviewed many large mortality/morbidity clinical trials in cardiovascular and renal disease areas and provided guidance to DBI review teams in reviewing the application of adaptive designs and innovative designs to registration clinical trials. He published many peer reviewed articles in Biometrics, Statistics in Medicine, Controlled Clinical Trials, Biometrical Journal, Journal of Biopharmaceutical Statistics, and Pharmaceutical Statistics. His research areas include multi-regional clinical trials, adaptive design/analysis, non-inferiority trials, factorial design clinical trials, utility of p-value distribution, and some of the advanced methodologies in central nervous system trials. He delivered more than 200 invited talks, lectures or short courses in many countries and published more than 80 articles.
Dr. Hung received two FDA/CDER Scientific Achievement Awards and many other awards for the recognition of his scientific contributions to the US FDA. He is the recipient of 2011 FDA Scientific Achievement Award – Excellence of Analytic Science. He also received awards for recognizing his contributions to the FDA guidance documents on adaptive designs and non-inferiority trial designs.
Dr. Hung is a Fellow of the American Statistical Association and an elected member of the International Statistical Institute. He served as an Editor-in-Chief for Journal of Pharmaceutical Statistics in 2009-2011. Currently, he serves as an Associate Editor for Statistics in Medicine.
