Randomised Response-Adaptive Designs in Clinical Trials presents methods for the randomised allocation of treatments to patients in sequential clinical trials. Emphasizing the practical application of clinical trial designs, the book is designed for medical and applied statisticians, clinicians, and statisticians in training. After introducing clinical trials in drug development, the authors assess a simple adaptive design for binary responses without covariates. They discuss randomisation and covariate balance in normally distributed responses and cover many important response-adaptive designs for binary responses. The book then develops response-adaptive designs for continuous and longitudinal responses, optimum designs with covariates, and response-adaptive designs with covariates. It also covers response-adaptive designs that are derived by optimising an objective function subject to constraints on the variance of estimated parametric functions. The concluding chapter explores future directions in the development of adaptive designs.show more

Review quote

"... an excellent textbook on this important topic. In general, the book is well written, easy to navigate, and definitely consistent with the high quality of other books in Monographs on Statistics and Applied Probability series by CRC Press. ... a well-structured and clearly presented textbook on randomized response-adaptive designs. ... Because the book offers a well-balanced mix of practical applications and theoretical results, a wide range of readers, from graduate students to applied statisticians with solid mathematical background, will find the book useful. Readers may find the authors' emphasis on the use of simulation methods to compare methods particularly useful."-The American Statistician, August 2015 "Atkinson and Biswas address [the] questions throughout in a thorough and interesting manner via a logical structure that makes navigating the text a simple and intuitive exercise. ... ideal for anyone looking to learn more about the growing field of response adaptive designs. An easy read, it is well written from the off set, logically advancing the mathematical complexity as the chapters proceed, making it useful for those new to the field of clinical trial design and seasoned trial statisticians alike. Through its use of numerous examples, it clearly achieves its stated aim; to elucidate the practical usefulness of this class of designs. Given their increasing popularity, it may well be one book you should consider adding to your collection sooner rather than later."-ISCB News, 59, June 2015 "This book is clearly written and well-structured for a graduate course as well as consulting statisticians. ... this book is particularly useful for the development of orphan drugs."-Biometrics, March 2015 "... the book covers a very broad range of response-adaptive designs and related issues. ... the book is comprehensively written and gives many exemplary applications from clinical practice. At the same time, the book is mathematically sound and also provides the underlying mathematical formulas and derivations. For these reasons, the book offers important content for applied statisticians but also for more theoretically interested mathematicians."-Biometrical Journal, 2014show more
