This volume is the outcome of the International School of Phar macology course sponsored as a NATO Advanced Study Institute and held in Erice (Sicily) at the Ettore Majorana Centre for Scientific Culture from October 3 through 12, 1980. The course, which consisted of lectures and teaching seminars, examined issues of international importance in all phases of drug development, assessment, and regu lation. In order to recreate both the atmosphere and substance of the meeting, a variety of materials are included here: the papers pre sented by the lecturers, a selection of key items from the supple mentary materials provided by the lecturers to the participants, notes on issues raised during the discussions, and accounts of certain special sessions arranged in response to interests expressed by those attending. The course covered two broad areas represented here by parts of the book. Part I, "Drug Assessment and Regulation," is based on the nine sessions of the course that ranged in focus from recent developments in the science of clinical pharmacology and drug development to discussions of whether and how the regulation of drug development can (or should) be harmonized internationally. In Part 11, "Postmarketing Surveillance," many aspects of this important subject are presented. Arguments outlining the potential benefits of national and international postmarketing surveillance systems are qualified by consideration of the problems inherent in devising and using these systems.

The very rapid pace of advances in biomedical research promises us a wide range of new drugs, medical devices, and clinical procedures. The extent to which these discoveries will benefit the public, however, depends in large part on the methods we choose for developing and testing them. Modern Methods of Clinical Investigation focuses on strategies for clinical evaluation and their role in uncovering the actual benefits and risks of medical innovation. Essays explore differences in our current systems for evaluating drugs, medical devices, and clinical procedures; health insurance databases as a tool for assessing treatment outcomes; the role of the medical profession, the Food and Drug Administration, and industry in stimulating the use of evaluative methods; and more. This book will be of special interest to policymakers, regulators, executives in the medical industry, clinical researchers, and physicians.

As the principal agency regulating food, drugs, medical devices, and biological products used by Americans, the U.S. Food and Drug Administration (FDA) serves one of the most critical consumer protection functions of the federal government. The FDA's reach is enormous, regulating products that represent roughly 25 percent of all consumer spending in the United States. Since 1992, however, federal funding for the agency has diminished, and the FDA's Center for Drug Evaluation and Research (CDER) currently relies on the fees it receives from the industry it regulates to fund the majority of its drug regulation functions. Prescription drug safety is receiving heightened press coverage and congressional scrutiny as a result of recent, highly publicized events, such as the recall of Vioxx because of its link to heart attacks, and the link between certain antidepressants (selective serotonin reuptake inhibitors, or SSRIs) and an increased risk of suicidal ideation in children. To address these concerns, the FDA in 2005 commissioned the Institute of Medicine (IOM) to conduct an independent assessment of the current U.S. drug safety system. In September 2006, the IOM committee released its report-The Future of Drug Safety: Promoting and Protecting the Health of the Public-which included 25 recommendations for improving the system for drug safety review. The committee identified four major vulnerabilities in the U.S. drug safety system: (1) chronic underfunding; (2) organization problems, particularly inadequate integration of pre-and postmarket data review; (3) a range of technical problems related to the insufficient quantity and quality of postmarket data and inadequate capability to systematically monitor the risks and benefits of drugs after marketing; and (4) unclear regulatory authority and insufficiently flexible regulatory tools. Since the IOM report was issued, the FDA has taken a number of steps toward implementing the recommended improvements. Like many government agencies, however, the FDA is financially strained by its existing responsibilities, and fully implementing the recommended improvements to the drug safety system would require significant financial commitments.The IOM report addressed some of the costs associated with its recommendations, but left many unanswered questions about the resources required to fully achieve the envisioned improvements. To better understand the types and magnitude of resources required to achieve the goals of the IOM report, the IOM's Forum on Drug Discovery, Development, and Translation convened a 1-day symposium in March 2007. Challenges for the FDA: The Future of Drug Safety, Workshop Summary explains the presentations and discussions in seven key areas: addressing the FDA's resource challenges; strengthening the scientific base of the agency; integrating pre- and postmarket review; enhancing postmarket safety monitoring; conducting confirmatory drug safety and efficacy studies; enhancing the value of clinical trial registration; and enhancing the FDA's postmarket regulation and enforcement.

New Drug Development: Second Edition provides an overview of the design concepts and statistical practices involved in therapeutic drug development. This wide spectrum of activities begins with identifying a potentially useful drug candidate that can perhaps be used in the treatment or prevention of a condition of clinical concern, and ends with marketing approval being granted by one or more regulatory agencies. In between, it includes drug molecule optimization, nonclinical and clinical evaluations of the drug’s safety and efficacy profiles, and manufacturing considerations. The more inclusive term lifecycle drug development can be used to encompass the postmarketing surveillance that is conducted all the time that a drug is on the market and being prescribed to patients with the relevant clinical condition. Information gathered during this time can be used to modify the drug (for example, dose prescribed, formulation, and mode of administration) in terms of its safety and its effectiveness. The central focus of the first edition of this book is captured by its subtitle, 'Design, Methodology, and Analysis'. Optimum quality study design and experimental research methodology must be employed if the data collected—numerical representations of biological information—are to be of optimum quality. Optimum quality data facilitate optimum quality statistical analysis and interpretation of the results obtained, which in turn permit optimum quality decisions to be made: Rational decision making is predicated on appropriate research questions and optimum quality numerical information. The book took a non-computational approach to statistics, presenting instead a conceptual framework and providing readers with a sound working knowledge of the importance of design, methodology, and analysis. Not everyone needs to be an expert in statistical analysis, but it is very helpful for work (or aspire to work) in the pharmaceutical and biologics industries to be aware of the fundamental importance of a sound scientific and clinical approach to the planning, conduct, and analysis of clinical trials.

This Brief discusses key statistical concepts that facilitate the inferential analysis of data collected from a group of individuals participating in a pharmaceutical clinical trial, the estimation of their clinical significance in the general population of individuals likely to be prescribed the drug if approved, and the related decision-making that occurs at both the public health level (by regulatory agencies when deciding whether or not to approve a new drug for marketing) and the individual patient level (by physicians and their patients when deciding whether or not the patient should be prescribed a drug that is on the market). These concepts include drug safety and efficacy, statistical significance, clinical significance, and benefit-risk balance.

This User’s Guide is intended to support the design, implementation, analysis, interpretation, and quality evaluation of registries created to increase understanding of patient outcomes. For the purposes of this guide, a patient registry is an organized system that uses observational study methods to collect uniform data (clinical and other) to evaluate specified outcomes for a population defined by a particular disease, condition, or exposure, and that serves one or more predetermined scientific, clinical, or policy purposes. A registry database is a file (or files) derived from the registry. Although registries can serve many purposes, this guide focuses on registries created for one or more of the following purposes: to describe the natural history of disease, to determine clinical effectiveness or cost-effectiveness of health care products and services, to measure or monitor safety and harm, and/or to measure quality of care. Registries are classified according to how their populations are defined. For example, product registries include patients who have been exposed to biopharmaceutical products or medical devices. Health services registries consist of patients who have had a common procedure, clinical encounter, or hospitalization. Disease or condition registries are defined by patients having the same diagnosis, such as cystic fibrosis or heart failure. The User’s Guide was created by researchers affiliated with AHRQ’s Effective Health Care Program, particularly those who participated in AHRQ’s DEcIDE (Developing Evidence to Inform Decisions About Effectiveness) program. Chapters were subject to multiple internal and external independent reviews.

Medical devices that are deemed to have a moderate risk to patients generally cannot go on the market until they are cleared through the FDA 510(k) process. In recent years, individuals and organizations have expressed concern that the 510(k) process is neither making safe and effective devices available to patients nor promoting innovation in the medical-device industry. Several high-profile mass-media reports and consumer-protection groups have profiled recognized or potential problems with medical devices cleared through the 510(k) clearance process. The medical-device industry and some patients have asserted that the process has become too burdensome and is delaying or stalling the entry of important new medical devices to the market. At the request of the FDA, the Institute of Medicine (IOM) examined the 510(k) process. Medical Devices and the Public's Health examines the current 510(k) clearance process and whether it optimally protects patients and promotes innovation in support of public health. It also identifies legislative, regulatory, or administrative changes that will achieve the goals of the 510(k) clearance process. Medical Devices and the Public's Health recommends that the U.S. Food and Drug Administration gather the information needed to develop a new regulatory framework to replace the 35-year-old 510(k) clearance process for medical devices. According to the report, the FDA's finite resources are best invested in developing an integrated premarket and postmarket regulatory framework.

Many people naturally assume that the claims made for foods and nutritional supplements have the same degree of scientific grounding as those for medication, but that is not always the case. The IOM recommends that the FDA adopt a consistent scientific framework for biomarker evaluation in order to achieve a rigorous and transparent process.
