The Future of Drug Safety: Promoting and Protecting the Health of the Public THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

The Future of Drug Safety: Promoting and Protecting the Health of the Public Preface The year 2006 marks the 100th anniversary of the signing of the Pure Food and Drug Act. During that century, drug regulation at the Food and Drug Administration (FDA) has evolved enormously, both in terms of statutory reforms (with major legislation in 1938, 1962, 1992, 1997, and 2002) and due to internal restructuring and growth in staff. Past changes have frequently been responses to problems in the functioning of the drug regulatory process. Although the agency has gained great respect and importance as one of the world’s premier regulatory bodies, recent drug safety events have called into question FDA’s regulatory decision-making and oversight processes, and caused the public to question its ability to accomplish a balanced evaluation of the safety and efficacy of the drugs it reviews and after their approval, of their performance under real-life conditions. In light of these developments, the Institute of Medicine (IOM) was asked by FDA to examine in detail the system of drug safety in this country. Our committee has, in the course of the last 15 months, undertaken this assessment. The result of our review is a series of recommendations that we believe will improve the drug safety system by strengthening clinical and epidemiological research, and the scientific basis of regulatory action. Although mindful of recent actions by FDA to improve its postmarketing decision-making process, the committee believes a more comprehensive response is required that acknowledges the need for vigilance throughout the lifecycle of a drug. Underlying our 25 recommendations is the fundamental view that the interests of the public are best served when safety and efficacy are considered together. However, factors including, but not limited to, the current organizational culture of the Center for Drug Evaluation and

OCR for page R1
The Future of Drug Safety: Promoting and Protecting the Health of the Public Research (CDER), combined with severe resource constraints and a problematic funding mechanism have impeded the development of a system that optimally integrates the safety and efficacy assessments along a drug’s lifecycle, particularly with regard to safety issues arising postmarketing. Further complicating this problem is the lack of a clearly established and consistently applied systematic process of making risk-benefit assessments, and an adequate base of human and technological resources required to meet the center’s critical responsibilities. The committee believes that CDER staff are a dedicated and talented group of public servants who currently lack the organization and resources to address all of the challenges before them and perform the crucial role of advancing and protecting public health in an increasingly complex environment. We believe that Congress needs to ensure that CDER is given the authority and assets (human, financial, technological) it requires. The center’s leaders have to be prepared to address the underlying cultural problems that divide and impair the optimal functioning of center staff, and to effectively use existing and new authorities and resources to achieve the center’s public health and regulatory mission. The committee’s recommendations pertaining to these issues must be viewed as a coherent package of solutions or strategies rather than a menu of choices. I would like to thank my colleagues on the committee for their extraordinary efforts. They have committed countless hours over the last 15 months in meetings, weekly conference calls, and a continuous stream of emails. They have passionately argued their positions, but also accommodated their colleagues and sought responsible consensus. I thank them for all they have done. I would also like to acknowledge the contributions of the IOM staff team—Kathleen Stratton, Alina Baciu, Amy Grossman, Ruth Kanthula, Andrea Pernack Anason, and consultant Renie Schapiro. Their dedication, guidance, and experience were of inestimable value to us in examining the highly complex process of drug evaluation and regulation. We could not have produced this report without them. The committee is grateful to everyone who spoke at our public meetings and who sent material for consideration. I also wish to thank the current and former staff at FDA and particularly CDER who spoke frankly with the committee and provided much needed insight into the workings of this agency. Sheila P. Burke, Chair
