The drug discovery and development process is getting longer, more expensive, and no better. The industry suffers from the same clinical attrition and safety-related market withdrawal rates today as it did 20 years ago. Industrialization of Drug Discovery: From Target Selection Through Lead Optimization scrutinizes these problems in detail, contrasting the promise of technology and industrialization with the challenges of using the tools available to their best advantage. The book explores early successes, examines the current state of the art, and provides a strategic analysis of the issues currently facing drug discovery. Introducing the historical background and current status of the industry, the book delineates the basic tenets underlying modern drug discovery, how they have evolved, and their use in various approaches and strategies. It examines, in detail, the regulations, requirements, guidelines, and draft documents that guide so many FDA actions. The editor devotes the remainder of the discussion to industrialization, compound and knowledge management functions, the drug screening process, collaboration, and finally, ethical issues. Drawing on real-life, from-the-trenches examples, the book elucidates a new approach to drug discovery and development. This modern-day, back-to-basics approach includes three steps: understand the science, unravel the story, and then intelligently apply the technology, bringing to bear the entire armamentarium of industrialization techniques, not just automation, to the discovery process. Using these steps, you can meet the goals of more specific targets, more selective compounds, and decreased cycle times. In effect, you can look for a bigger needle in a smaller haystack. Daniel E. Levy, editor of the Drug Discovery Series, is the founder of DEL BioPharma, a consulting service for drug discovery programs. He also maintains a blog that explores organic chemistry.

This volume will consider one of ICH's major categories, Safety i.e. topics relating to in vitro and in vivo pre-clinical studies (Carcinogenicity Testing, Genotoxicity Testing, etc.). Since the start of the ICH process, many guidelines have been written, but even after ICH6 no explanations have been given during a formal Congress about the background of the ICH Guidance documents. Even more important than what has been written, might have been those thoughts of the experts that are not included in the Guidance documents. Why has the guideline been written as it is written, and why have some aspects been deleted. These and other related questions are the contents of this book, written by experts who were involved in the ICH process. Furthermore, the chapters will contain discussions on the "lessons learnt" and "future developments".
