Buckley LA, Bebenek I, Cornwell PD, Hodowanec A, Jensen EC, Murphy C, Ghantous HN

Drug development is a term used to define the entire process of bringing a new drug or device to market. It is an integrated, multidisciplinary endeavor that includes drug discovery, chemistry and pharmacology, nonclinical safety testing, manufacturing, clinical trials, and regulatory submissions. This report summarizes presentations of a workshop entitled "Drug Development 101," held at the 39th Annual Meeting of the American College of Toxicology in West Palm Beach, Florida. The workshop was designed to provide an introductory overview of drug development. Experienced scientists from industry and government provided overviews of each area, with a focus on safety assessment, and described some of the challenges that can arise. The role of chemistry and manufacturing was discussed in the context of early- and late-stage product development and approaches to assess, control, and limit impurities. The toxicologic assessment was emphasized in early-phase development, from the selection of a candidate drug through the determination of a first-in-human starting dose. Clinical trial development was discussed in the context of regulatory requirements and expectations. The final topic of issues and considerations in the review processes of different types of submissions to Food and Drug Administration included advice for best practices in authoring good Investigational New Drug and New Drug Application/Biologic License Application submissions and interacting effectively with regulatory reviewers.
