In 2010 the Institute of Medicine (IOM) recommended a framework for the evaluation of biomarkers in the chronic disease setting. Published in the book Evaluation of Biomarkers and Surrogate Endpoints in Chronic Disease, the framework is intended to bring consistency and transparency to the previously disparate process of biomarker evaluation. Following the book's release, the IOM convened a 2-day discussion forum in Washington, DC, in order to provide an opportunity for stakeholders to learn about, react to, and discuss the book. Presentations reviewed the authoring committee's work process, recommendations, and provided perspectives on the book from the point of view of participants. Thomas Fleming, professor of biostatistics and statistics at the University of Washington, gave a keynote presentation on the critical issues in the validation of surrogate endpoints, a specific use of a biomarker. The present volume recounts the discussion forum proceedings, focusing in turn on each represented sector. A summary of Dr. Fleming's presentation then sets the committee's recommendations within the context of biomarker utilization. Lastly, this summary examines the main themes raised by stakeholders, and the challenges and opportunities presented to stakeholders by the book's recommendations.

The volume aim to be a comprehensive overview of the drug and biologic development process that is often called “the valley of death” (pre-IND through approval) where high costs of studies and high rates of product failure are part of the drug development landscape. Imaging tools can serve in this period by adding high value data, the images and the kinetic information they can provide, and cost-effective development alternative tools which potentially improve pivotal study designs. Imaging may identify safety issues early such as unwanted organ or tissue distributions, and then can serve advanced development with added certainty of a drug or biologic’s success to senior corporate management and investors. There are numerous textbooks, reference texts and treatises on medical imaging technologies, teaching tools on medical cases and physics books on the science of detector and computer interface systems. Rarely, in each of these are examples of medical imaging protocols and animal models of disease i.e. a text on methodology in drug development is currently unavailable.

The perioperative care of individuals with neurologic compromise is critically important, yet it is only one dimension of the rich relationship between anaesthesiology and the neurosciences. The mechanism of everyday therapeutic interventions such as anaesthesia and analgesia is exciting neuroscience in its own right. At the new frontier of outcomes studies lies the question of how the perioperative period might impact the brain. For example, questions related to anaesthetic neurotoxicity, delirium, and cognitive dysfunction pose critical challenges for the field. The Oxford Textbook in Neuroscience and Anaesthesiology addresses the exciting field of neuroanaesthesiology in a new and stimulating way. In twenty eight chapters, the neuroscientific basis of anaesthesiology, the full spectrum of clinical neuroanaesthesia, and the care of neurologic patients undergoing non-neurologic surgery are explored in one comprehensive textbook for the first time. The first section considers the neural mechanisms of general anaesthetics, cerebral physiology, the neurobiology of pain, and more. The second section explores the care of patients with neurologic disease in the operating room or intensive care unit. These clinical chapters systematically treat the perioperative considerations of both brain and spine surgery, and provide introductions to neurocritical care and pediatric neuroanaesthesia. The final section outlines the care of neurologic patients undergoing non-neurologic surgery. It examines key connections of neurology and anaesthesiology, examining how conditions such as dementia, stroke, or epilepsy interface with the perioperative period. Each chapter has been carefully crafted to be concise yet highly informative, reflecting the cutting edge of neuroscience and neuroanaesthesiology. This international textbook gathers the best available expertise of authors and leaders worldwide. Includes access to online-only content, including more than 20 cases and more than 90 questions that can be used in presentations and teaching sessions.

Presents elements of clinical trial methods that are essential in planning, designing, conducting, analyzing, and interpreting clinical trials with the goal of improving the evidence derived from these important studies This Third Edition builds on the text’s reputation as a straightforward, detailed, and authoritative presentation of quantitative methods for clinical trials. Readers will encounter the principles of design for various types of clinical trials, and are then skillfully guided through the complete process of planning the experiment, assembling a study cohort, assessing data, and reporting results. Throughout the process, the author alerts readers to problems that may arise during the course of the trial and provides common sense solutions. All stages of therapeutic development are discussed in detail, and the methods are not restricted to a single clinical application area. The authors bases current revisions and updates on his own experience, classroom instruction, and feedback from teachers and medical and statistical professionals involved in clinical trials. The Third Edition greatly expands its coverage, ranging from statistical principles to new and provocative topics, including alternative medicine and ethics, middle development, comparative studies, and adaptive designs. At the same time, it offers more pragmatic advice for issues such as selecting outcomes, sample size, analysis, reporting, and handling allegations of misconduct. Readers familiar with the First and Second Editions will discover revamped exercise sets; an updated and extensive reference section; new material on endpoints and the developmental pipeline, among others; and revisions of numerous sections. In addition, this book: • Features accessible and broad coverage of statistical design methods—the crucial building blocks of clinical trials and medical research -- now complete with new chapters on overall development, middle development, comparative studies, and adaptive designs • Teaches readers to design clinical trials that produce valid qualitative results backed by rigorous statistical methods • Contains an introduction and summary in each chapter to reinforce key points • Includes discussion questions to stimulate critical thinking and help readers understand how they can apply their newfound knowledge • Provides extensive references to direct readers to the most recent literature, and there are numerous new or revised exercises throughout the book Clinical Trials: A Methodologic Perspective, Third Edition is a textbook accessible to advanced undergraduate students in the quantitative sciences, graduate students in public health and the life sciences, physicians training in clinical research methods, and biostatisticians and epidemiologists. This book is accompanied by downloadable files available below under the DOWNLOADS tab. These files include: MATHEMATICA program – A set of downloadable files that tracks the chapters, containing code pertaining to each. SAS PROGRAMS and DATA FILES used in the book. The following software programs, included in the downloadables, were developed by the author, Steven Piantadosi, M.D., Ph.D: RANDOMIZATION – This program generates treatment assignments for a clinical trial using blocked stratified randomization. CRM – Implements the continual reassessment methods for dose finding clinical trials. OPTIMAL – Calculates two-stage optimal phase II designs using the Simon method. POWER – This is a power and sample size program for clinical trials. Executables for installing these programs can also be found at https://risccweb.csmc.edu/biostats/. Steven Piantadosi, MD, PhD, is the Phase One Foundation Distinguished Chair and Director of the Samuel Oschin Cancer Institute, and Professor of Medicine at Cedars-Sinai Medical Center in Los Angeles, California. Dr. Piantadosi is one of the world’s leading experts in the design and analysis of clinical trials for cancer research. He has taught clinical trials methods extensively in formal courses and short venues.
