POCOCK Medical Computing and Statistics Group, Medical School, University of Edinburgh SUMMARY In clinical trials with sequential patient entry, fixed sample size designs are unjustified on ethical grounds and sequential designs are often impracticable. RESULTS: Thirty-seven trials with an adaptive design and health economic analysis were identified. It was not clear whether the health economic analysis accounted for the adaptive design in 17/37 trials where this was thought necessary, nor whether health economic outcomes were used at the interim analysis for 18/19 of trials with results.

Previous Lectures • Definition of a clinical trial • The drug development process • How different aspects of the effects of a drug are However, a barrier to realising the promise of precision medicine is the inappropriate use of traditional clinical trial design and analysis, which rely on estimates of population-averaged effects. In this course we introduce the concept of precision medicine and cover innovative approaches. Objective To investigate the distribution, design characteristics, and dissemination of clinical trials by funding organisation and medical specialty. Design Cross sectional descriptive analysis. Data sources Trial protocol information from clinicaltrials.gov, metadata of journal articles in which trial results were published (PubMed), and quality metrics of associated journals from SCImago ... Praise for the First Edition of Design and Analysis of Clinical Trials "An excellent book, providing a discussion of the clinical trial process from designing the study through analyzing the data, and to regulatory requirement . . . could easily be used as a classroom text to understand the process in the new drug development area."

Introduction. Typically in clinical trials, a single 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 result. Section 'A strategy for design and analysis of clinical trials discusses our proposed strategy for trial design and analysis. We describe how to do a sample size calculation for a trial using the RMST difference. We also consider the choice of suitable values of t ∗ at the design and analysis stages. The sequence of courses, Design and Conduct of Clinical Trials I and II, is designed to introduce the complex issues surrounding the analysis and interpretation of clinical trials. In Design and Conduct of Clinical Trials II, students will learn how to select the appropriate analytic method depending on the Mouse clinical...
