Current Topics in Nonclinical Drug Development

This third volume in the series focuses on such germane issues as the weight of evidence approach, applying the 3Rs (replacement, reduction, and refinement), personalized drug therapies, and oncology therapeutics, among others. Volumes in this series are aimed at toxicologists, toxicologic pathologists, regulators, and study directors dealing with issues in study design, evaluation of findings, and presentation of data. In addition, the series will serve as an aid to academicians and graduate students studying nonclinical drug development. Key Features:Explores the critical issues and current topics important in nonclinical drug developmentDeals with day-to-day issues in study design, evaluation of findings, and presentation of dataAids academicians and graduate students pursuing research related to nonclinical drug developmentDelves into both the art and science of nonclinical drug development and its impact on translational medicine and human safety

Dr. Wojcinski has extensive experience as a Study Director, Study Pathologist, and Review Pathologist for numerous acute and repeated dose toxicity studies, including carcinogenicity studies. Throughout his career, he has managed successful cross-functional drug development teams in CNS, Metabolic Diseases, and Dermatology therapeutic areas. As Therapeutic Area Leader for Dermatology at Pfizer, Dr. Wojcinski was responsible for development and implementation of the safety and risk management strategies for, what was then, a new therapeutic area. He has also been directly involved in the preparation of pre-IND documents, Nonclinical Safety Assessments for IND/IMPD/NDA/MAA, Investigator’s Brochures, and labeling (USPI, SmPC) negotiations in CNS, anti-infective, and dermatology therapeutic areas. Dr. Wojcinski has had numerous interactions with regulatory agencies in the United States, Europe, Canada, and Australia for compounds at various stages of development. He has also provided pathology consultation and histopathology peer review on several projects in various therapeutic areas, including respiratory infections, dermatitis, and ophthalmic disease and served on Pathology Working Groups. Dr. Wojcinski is a full member of numerous professional societies including the American College of Veterinary Pathologists, Society of Toxicologic Pathologists, Society of Toxicology, American College of Toxicology, American Veterinary Medical Association, Canadian Veterinary Medical Association, Canadian Association of Veterinary Pathologists, Regulatory Affairs Professionals Society, and Roundtable of Toxicology Consultants. He has served as President of the Dermal Toxicity Specialty Section of the Society of Toxicology, an Associate Editor for the Society of Toxicologic Pathology, Editor of The Scope for the Society of Toxicologic Pathology, and Chair of the Society of Toxicologic Pathology Recruitment Subcommittee. Dr. Wojcinski has lectured at the Ontario Veterinary College and the University of Maryland and authored/co-authored numerous scientific reports, manuscripts, and book chapters. Most recently, he was Co-Editor for The Illustrated Dictionary of Toxicologic Pathology & Safety Science, First Edition, 2019.

Philip Bentley is Principal Consultant at Toxicodynamix International LLC. He studied biochemistry at the University of Hull, UK, graduating with a BSc in 1970 and a PhD in 1974. He had postdoctoral fellowships at the Universities of Basel. Switzerland and Mainz, Germany. His postdoctoral research centered upon formation and inactivation of reactive metabolites and the enzymes involved in the metabolism of foreign compounds. In 1979 he joined the Investigative Toxicology group (known as Cell Biology) in the Toxicology Department of Ciba-Geigy, Basel, Switzerland and remained with the company, later Novartis, until 2014. In these 35 years he held various management positions in Europe and the USA with responsibility for Investigative Toxicology; Drug Metabolism; Drug Metabolism and Toxicology; Preclinical Safety Europe; Drug Metabolism and Pharmacokinetics; Toxicology/Pathology USA; Preclinical Safety USA and Global Preclinical Safety. In these positions he contributed to the registration of more than 45 marketed drug products and the preparation of several hundred IND’s. He has vast experience in the areas of drug metabolism and disposition, toxicology/pathology, genetic toxicology, pharmacokinetics/toxicokinetics and all aspects of investigative toxicology. He is well grounded in biochemistry, cell biology, molecular biology and pharmacology with the ability to integrate data from the different preclinical disciplines to enable translation to determine the clinical relevance of the findings. He is very familiar with global drug registration requirements and working on global projects. He has authored more than 80 scientific publications, has lectured in toxicology at the University of Basel for more than 30 years, and is a past President of the European Society of Biochemical Pharmacology and the Swiss Society of Toxicology. He was a member of the PhRMA/IQ Preclinical Leadership (DruSafe) Committee for 16 years, a member of the advisory board of the PSTC Biomarker consortium and a member of the expert working group for revision of the ICH S2 guidance on genotoxicity testing and the PhRMA expert group on genotoxic impurities.

Pritam S. Sahota, Global ToxPath LLC, Kennewick, Washington, USA has extensive experience in toxicologic pathology and drug development within the framework of nonclinical safety assessment of pharmaceuticals. Dr. Sahota was previously Executive Director and Head of Pathology, Preclinical Safety, at Novartis Pharmaceuticals, East Hanover, New Jersey. He obtained his veterinary medicine (BVSc) and veterinary pathology degrees (MSc and PhD) from Punjab Agricultural University, India. He is a Diplomate of the American Board of Toxicology. After receiving his PhD in 1976, he started working as a toxicologic pathologist at Dawson Research Corporation (DRC), Orlando, Florida, a contract research organization involved in the preclinical safety evaluation of drugs and chemicals. At DRC, he received increasing responsibility over the next 10 years (Toxicologic Pathologist, Senior Toxicologic Pathologist, and Scientific Director). As a Scientific Director, he was responsible for the scientific aspects of pathology as well as toxicology at DRC. While working briefly for Dynamac Corporation, Research Triangle Park, North Carolina (1986-87), he conducted retrospective scientific audits of 23 NTP carcinogenicity studies and participated in discussions with the representatives of NTP, FDA, and EPA to review the results of scientific audits of over 200 NTP carcinogenicity studies. In 1987, he joined Ciba-Geigy Pharmaceuticals in New Jersey as Head/Manager of pathologists in preclinical safety and was also responsible for establishing pathology peer review, quality control and scheduling systems. He continued to work primarily in this position with increasing responsibilities at Ciba-Geigy and then Novartis Pharmaceuticals (after Ciba-Sandoz merger in 1997) to become director and eventually Executive Director and Head of pathology. During this time, he also served as an international project team representative for a number of successfully marketed CNS, immunosuppression, diabetes, and cardiovascular drugs, including Diovan, which eventually became one of the 15 all-time, best-selling prescription drugs. He also held an adjunct academic appointment of Assistant Professor at the University of Medicine and Dentistry, New Jersey, for 8 years. He successfully led several global preclinical safety initiatives at Novartis, including patient centricity, review of best practices in cardio-toxicity and ocular toxicity as well as evaluation of rodent carcinogenicity potential based on non-carcinogenicity data to minimize future delays in regulatory submissions. Since retirement from Novartis Pharmaceuticals in 2012, Dr. Sahota has been the President of Global ToxPath LLC located in Kennewick, WA, USA (Toxicologic Pathology Consultancy). As Lead Editor, he published following books with CRC Press/Taylor & Francis: (1) Toxicologic Pathology: Nonclinical Safety Assessment, First Edition, 2013; (2) Toxicologic Pathology: Nonclinical Safety Assessment, Second Edition, 2018; and The Illustrated Dictionary of Toxicologic Pathology & Safety Science, First Edition, 2019.
