Bioequivalence and Statistics in Clinical Pharmacology: Chapman & Hall/CRC Biostatistics Series

Autor Scott D. Patterson, Byron Jones
en Limba Engleză Paperback – 31 mar 2021
Maintaining a practical perspective, Bioequivalence and Statistics in Clinical Pharmacology, Second Edition explores statistics used in day-to-day clinical pharmacology work. The book is a starting point for those involved in such research and covers the methods needed to design, analyze, and interpret bioequivalence trials; explores when, how, and why these studies are performed as part of drug development; and demonstrates the methods using real world examples.




Drawing on knowledge gained directly from working in the pharmaceutical industry, the authors set the stage by describing the general role of statistics. Once the foundation of clinical pharmacology drug development, regulatory applications, and the design and analysis of bioequivalence trials are established, including recent regulatory changes in design and analysis and in particular sample-size adaptation, they move on to related topics in clinical pharmacology involving the use of cross-over designs. These include, but are not limited to, safety studies in Phase I, dose-response trials, drug interaction trials, food-effect and combination trials, QTc and other pharmacodynamic equivalence trials, proof-of-concept trials, dose-proportionality trials, and vaccines trials.




This second edition addresses several recent developments in the field, including new chapters on adaptive bioequivalence studies, scaled average bioequivalence testing, and vaccine trials.




Purposefully designed to be instantly applicable, Bioequivalence and Statistics in Clinical Pharmacology, Second Edition provides examples of SAS and R code so that the analyses described can be immediately implemented. The authors have made extensive use of the proc mixed procedures available in SAS.

Recenzii

"The two authors are well-respected statisticians with numerous publications in BE and broad pharmaceutical industry experience. … The book is written in plain language and statistics is presented with minimum mathematical proof, which makes it a great introduction and reference for statisticians and clinical pharmacologists. With case studies and associated SAS and R codes included in the book and website, both statisticians and clinical pharmacologists will find this book helpful in understanding the context to use a method and implementing the ready-to-use codes. Particularly, each chapter begins with an interesting real-life story of the authors working as statisticians in the pharmaceutical industry, which makes the reading delightful. …In summary, Bioequivalence and Statistics in Clinical Pharmacology, Second Edition, provides an update on regulatory recommendations, statistical methods, and applications in clinical pharmacology and BE studies to support drug product development. With its inclusion of SAS and R codes, this book will be a valuable reference for pharmaceutical scientists, statisticians, and regulators working in these areas."
—Wangjie Sun and Wenlei Jiang, US Food and Drug Administration, in Journal of the American Statistical Association, January 2018
"This book is a second edition of the authors’ take on the concepts and methods in the analysis and design of bioequivalence studies, supported by references to regulation authorities’ guidelines ... The authors are working in the pharmaceutical industry and therefore bring a view from the inside compared to the other reference work in the field by academics … Throughout the book, different examples with data and codes are provided both showing and not showing bioequivalence to facilitate the learning process. … To conclude, this book covers efficiently the statistical methods of bioequivalence testing and their many applications in clinical pharmacology. Furthermore, the dense reference list provides a helpful guide for the reader to go in deeper details on topics of interest."
—Julie Bertrand, Faculté de Médecine Bichat, IAME, in Journal of Biopharmaceutical Statistics, May 2017
"The first edition of Bioequivalence and Statistics in Clinical Pharmacology was a classic text book for researchers and statisticians in the field of clinical pharmacology and pharmaceutical industry. This new second edition is a timely update with the inclusion of new areas such as adaptive bioequivalence trials, scaled average bioequivalence testing, and vaccine trials. This is one of few books in the literature with the focus on statistical issues in clinical pharmacology and bioequivalence. The topics it covers are critical for understanding the pharmacology of an investigational drug, and are becoming increasingly important in the era of precision medicine. The book is just as well structured as the first edition, in an accessible, thorough, and clear manner. Case studies and associated SAS code included in the book are extremely helpful. In summary, the book is a most welcome addition to the collection of pharmaceutic statisticians and researchers in clinical pharmacology."
Liang Fang, Director of Biostatistics, Gilead Sciences Inc.
"Bioequivalence and Statistics in Clinical Pharmacology, Second Edition, provides readers with a statistical background of bioequivalence and presents several special topics in clinical pharmacology. This second edition contains updated and extended discussions of these topics and includes new chapters on adaptive bioequivalence studies, scaled average bioequivalence, and vaccine trials. The book’s presentation is comprehensive and clear, and is complimented by numerous illustrations, examples, and computer programs with data analyses. Scientists and practitioners working in industry, regulatory authorities, and academia will find this book useful, interesting, and enjoyable due to the delightful and instructive stories featured in the introductions of each chapter, the various important and relevant topics covered by these chapters, and the informative and practical technical appendices."
Laszlo Endrenyi, Professor Emeritus, University of Toronto
Praise for the First Edition:
"… the book provides a good introduction to common uses of statistics in early phases of the drug development process by using a good mix of technical detail, intuitive understanding and factual knowledge. … personal accounts together with the numerous real data examples which are accompanied by SAS code for analysis and the opportunity to download the data to gain first-hand experience are the best features of the book. … the authors did a fine job in providing an introduction to statistics in the early stages of the drug development process. The availability of real example data allows the reader to engage himself easily in the topic and the long experience of the authors ensures that many different aspects of pharmacological studies are discussed."
—Thomas Jaki, Lancaster University, Journal of the Royal Statistical Society, Series A, 2010
"I really enjoyed reading this book. Each chapter includes an excellent introduction based on Scott Patterson's experience working as a biometrician. This will especially be of interest to young statisticians starting their career in the pharmaceutical industry. Therefore, I strongly recommend this book to all pharmaceutical statisticians to learn more of the challenging statistical problems being generated in drug development. In addition, the presented material provides a springboard for all scientists from academia who are looking to do research in this area of medical applications."
—Dieter Haushcke, Biometrics, September, 2006
"The authors formulate bioequivalence exhaustively and clearly. … Given the background of the authors, they constitute a key piece of social information in understanding the context in which clinical pharmacology research develops within the pharmaceutical industry."
