Toxicologic Pathology

The new edition provides practical and timely information for toxicologic pathologists working in drug discovery and development. The introductory concept chapters are consolidated into two more concise and better-organized introductory chapters. The two concept chapters introduce the reader to pharmaceutical R&D, the role of the pathologist in the process, and critical partner scientific disciplines with whom the pathologist will collaborate. In this revision, the organ system chapters incorporate more consistent commentary and guidance on the molecular mechanism of action, human translational relevance, and regulatory impact of pathological findings as they are described in these chapters.

Key Features:

• Aids scientists in understanding spontaneously occurring and compound-related pathological findings
• Features three new well-respected scientists on the editorial team
• Includes more consistent commentary and guidance in the organ system chapters

Page R. Bouchard is a R&D strategy consultant to the biopharmaceutical industry with a focus on advanced therapies and emerging technologies. He retired from Novartis Pharmaceuticals in 2021 where he was the Senior Vice President and Chief Scientific Officer of the Novartis Gene Therapy Unit, and prior to that the Vice President and Global Head of Preclinical Safety. Dr. Bouchard received his DVM from Tufts Veterinary School, residency training in anatomic pathology at Cornell School of Veterinary Medicine, and ACVP board certification in 1993. Dr. Bouchard has worked as a toxicologic pathologist and project team toxicologist at Searle Pharmaceuticals, Head of Preclinical Safety at Genetics Institute, Head of Pathology and Investigative Safety at Wyeth Pharmaceuticals, Head of Preclinical Safety at Millennium Pharmaceuticals, Head of Preclinical R&D at Archemix Pharmaceuticals, and finally in his leadership roles at Novartis Pharmaceuticals. Dr. Bouchard has worked across all phases of drug discovery and development, and virtually all therapeutic modalities and disease areas. He has had the privilege of working with many companies and regulatory authorities across all regions of the world. Though the focus of his career has been managing R&D strategy and project portfolio, toxicologic pathology is the scientific lens through which he has viewed the process. Dr. Bouchard has been an active member of the ACVP and STP and has served in a variety of volunteer roles for both organizations. He is passionate about continually advancing and modernizing the science and practice of anatomic and clinical pathology and challenging pathologists to adopt new tools and fully appreciate the use, context and impact of their work.
