This year, the 110th Congress of the United States will consider a drug safety legislation that could have a direct effect on the entire biomedical community. The legislation could affect the ease with which drugs can be developed, proven safe and effective, and reach the public in a timely manner. The Food and Drug Administration (FDA) plays a pivotal role in analyzing the benefits and risks of new therapies and also must ensure continued monitoring of products once they reach the market. Without an optimally functioning FDA, new therapies discovered by some of the world's most talented researchers and developed by our pharmaceutical industry will have little chance to reach patients in a timely manner. A new legislation must be carefully considered to prevent negative unintentional consequences. Instead, the legislation must effectively improve drug safety, ensure access to new drugs, and foster the development of innovative new treatments.Efforts to increase the effectiveness and efficiency of FDA are important and well justified. The agency is currently facing the challenge of strengthening the review of product safety at both pre-approval and post-marketing stages. Several months ago, a committee of academic scientists and clinicians, research advocates, and representatives of the patient community was convened to recommend ways in which policy makers in the Congress and FDA could further strengthen product evaluation. The resulting report, Drug Safety and Drug Efficacy: Two Sides of the Same Coin, released March 9th,55http://www.focr.org/drugsafetyreport.htm is a proposal for improving drug safety, ensuring new drug access and strengthening the FDA.In the view of this committee, drug efficacy and safety should continue to be evaluated simultaneously by the existing FDA division that is most familiar with the product under review, rather than by a separate center or agency. Furthermore, an expanded and systematic approach to safety surveillance should be implemented. Post-marketing surveillance should utilize a variety of sources to routinely identify and obtain accurate data, have the computational and statistical ability to analyze large-scale information sets, and incorporate emerging scientific tools to improve the methods of distinguishing and describing safety and efficacy signals. FDA currently lacks the resources and personnel to fully integrate the science and technology necessary to develop a systematic approach to safety surveillance. To ensure that FDA has adequate resources, there must be an appropriate commitment of public funds by congress and not exclusively through increases in funds required from the pharmaceutical industry. In addition to resources, FDA will require employee training programs and a commitment to the advancement of science through the Critical Path Initiative66http://www.fda.gov/oc/initiatives/criticalpath/ to strengthen safety monitoring. Although the current passive surveillance method does provide useful information, it is not as efficient as it could be in detecting emerging safety and efficacy data; it should be strengthened. In addition, an automated post-marketing system of drug monitoring should be created using existing public and private databases. Such a system will improve the agency's ability to identify risks of new marketed products in a timelier manner and to evaluate risks along with the health benefits provided by the product.A benefit-risk approach across a product life cycle is the cornerstone of drug development and should be the foundation of drug regulation as well. This is particularly true with regard to drugs for serious and life-threatening diseases like cancer, refractory cardiovascular disease, and neurodegenerative diseases. To focus solely on drug safety without consideration of drug benefit, the severity of the underlying disease, the effectiveness of the product, and the availability of alternative therapies, risks creating a chilling effect on the development of new treatments for patients most in need of innovation.As Congress considers drug safety legislation, it is an opportunity to strengthen and increase the capabilities and efficiency of FDA in all phases of its work. Simply stated, Congress must invest more in the FDA if it expects it to properly carry out its mandate. Whereas recent policy recommendations contain elements that would provide assistance to an overburdened agency, proposals focused on increasing FDA authority and regulatory oversight do not fully address ways to insure innovation and improvements in overall public health.The goal of the report commissioned by the committee is to provide lawmakers with a balanced perspective from a broad group of physician investigators and advocates who have extensive experience in the field of drug development for patients with serious diseases. The new legislation must achieve the goals of enhancing the drug approval and monitoring process and optimizing the productivity of FDA. Unintentional consequences, such as restricting or slowing patient access to life-saving treatments, or discouraging innovative product development, would be detrimental for the American public. Over-regulation and subsequent slowing of the drug approval process increases the cost of medical care, thereby decreasing access to medications because of their expense. To best position FDA for continued success, the committee encourages members of Congress and FDA officials to implement policies to address the following recommendations:It is the view of the report's authoring committee that with proper advancement, support, and leadership, FDA can move into the 21st century and firmly remain the gold standard of science-based drug review and safety monitoring.
