On June 20, 2012, the House of Representatives passed, by voice vote and under suspension of the rules, S. 3187 (EAH), the Food and Drug Administration Safety and Innovation Act, as amended. This bill would reauthorize the FDA prescription drug and medical device user fee programs (which would otherwise expire on September 30, 2012), create new user fee programs for generic and biosimilar drug approvals, and make other revisions to other FDA drug and device approval processes. It reflects bicameral compromise on earlier versions of the bill (S. 3187 ES], which passed the Senate on May 24, 2012, and H.R. 5651 EH], which passed the House on May 30, 2012). The following CRS reports provide overview information on FDA's processes for approval and regulation of drugs: CRS Report R41983, How FDA Approves Drugs and Regulates Their Safety and Effectiveness, by Susan Thaul; CRS Report RL33986, FDA's Authority to Ensure That Drugs Prescribed to Children Are Safe and Effective, by Susan Thaul; CRS Report R42130, FDA Regulation of Medical Devices, by Judith A. Johnson; CRS Report R42508, The FDA Medical Device User Fee Program, by Judith A. Johnson. (Note: The rest of this report has not been updated since November 10, 2011.) With the Best Pharmaceuticals for Children Act (BPCA) and the Pediatric Research Equity Act (PREA), Congress authorized the Food and Drug Administration (FDA) to offer drug manufacturers financial and regulatory incentives to test their products for use in children. Congress extended both programs with the FDA Amendments of 2007 (FDAAA) and, because of the programs' sunset date, must act before October 1, 2012, to continue them. This report presents the historical development of BPCA and PREA, their rationale and effect, and FDAAA's impact. The report also discusses pediatric drug issues that remain of concern to some in Congress. Most prescription drugs have never been the subject of studies specifically designed to test their effects on children. In these circumstances, clinicians, therefore, may prescribe drugs for children that FDA has approved only for adult use; this practice is known as off-label prescribing. Although some clinicians may believe that the safety and effectiveness demonstrated with adults would hold for younger patients, studies show that the bioavailability of drugs-that is, how much gets into a patient's system and is available for use-varies in children for reasons that include a child's maturation and organ development and other factors. The result of such off-label prescribing may be that some children receive ineffective drugs or too much or too little of potentially useful drugs; or that there may be side effects unique to children, including effects on growth and development. Drug manufacturers are reluctant to test drugs in children because of economic, ethical, legal, and other obstacles. Market forces alone have not provided manufacturers with sufficient incentives to overcome these obstacles. BPCA and PREA represent attempts by Congress to address the need for pediatric testing. FDA had tried unsuccessfully to spur pediatric drug research through administrative action before 1997. With the FDA Modernization Act of 1997 (FDAMA, P.L. 105-115), Congress provided an incentive: if a manufacturer completed pediatric studies that FDA requested, the agency would extend the company's market exclusivity for that product for six months, not approving the sale of another manufacturer's product during that period. In 2002, BPCA (P.L. 107-109) reauthorized this program for five years. In 1998, to obtain pediatric use information on the drugs that manufacturers were not studying, FDA published the Pediatric Rule, which required manufacturers to submit pediatric testing data at the time of all new drug applications.

The Food and Drug Administration (FDA) is a regulatory agency within the Department of Health and Human Services. A key responsibility is to regulate the safety and effectiveness of drugs sold in the United States. FDA divides that responsibility into two phases: preapproval (premarket) and postapproval (postmarket). FDA reviews manufacturers' applications to market drugs in the United States; a drug may not be sold unless it has FDA approval. The agency continues its oversight of drug safety and effectiveness as long as the drug is on the market. Beginning with the Food and Drugs Act of 1906, Congress has incrementally refined and expanded FDA's responsibilities regarding drug approval and regulation. The progression to drug approval begins before FDA involvement. First, basic scientists work in the laboratory and with animals; second, a drug or biotechnology company develops a prototype drug. That company must seek and receive FDA approval, by way of an investigational new drug (IND) application, to test the product with human subjects. Those tests, called clinical trials, are carried out sequentially in Phase I, II, and III studies, which involve increasing numbers of subjects. The manufacturer then compiles the resulting data and analysis in a new drug application (NDA). FDA reviews the NDA with three major concerns: (1) safety and effectiveness in the drug's proposed use; (2) appropriateness of the proposed labeling; and (3) adequacy of manufacturing methods to assure the drug's identify, strength, quality, and identity. The Federal Food, Drug, and Cosmetic Act (FFDCA) and associated regulations detail the requirements at each step. FDA uses a few special mechanisms to expedite drug development and the review process when a drug might address an unmet need or a serious disease or condition. Those mechanisms include accelerated approval, animal efficacy approval, fast track applications, and priority review. Once a drug is on the U.S. market (following FDA approval of the NDA), FDA continues to address drug production, distribution, and use. Its activities, based on ensuring drug safety and effectiveness, address product integrity, labeling, reporting of research and adverse events, surveillance, drug studies, risk management, information dissemination, off-label use, and directto- consumer advertising, all topics in which Congress has traditionally been interested. FDA seeks to ensure product integrity through product and facility registration; inspections; chain-of-custody documentation; and technologies to protect against counterfeit, diverted, subpotent, adulterated, misbranded, and expired drugs.

UPDATE: S. 3187, the Food and Drug Administration Safety and Innovation Act, scheduled for floor consideration, is an amended version of S. 2516, reported by the Senate Committee on Health, Education, Labor, and Pensions. The House Committee on Energy and Commerce voted favorably to report H.R. 5651, the Food and Drug Administration Reform Act of 2012. Both the Senate and House bills include titles to reauthorize FDA prescription drug and medical device user fee programs, authorize new user fee programs for generic drugs and biosimilar biological products, and amend the Federal Food, Drug, and Cosmetic Act regarding the regulation of drugs and medical devices.

More than 200,000 U.S. military personnel participated in atmospheric nuclear weapons tests between 1945 and the 1963 Limited Nuclear Test Ban Treaty. Questions persist, such as whether that test participation is associated with the timing and causes of death among those individuals. This is the report of a mortality study of the approximately 70,000 soldiers, sailors, and airmen who participated in at least one of five selected U.S. nuclear weapons test series1 in the 1950s and nearly 65,000 comparable nonparticipants, the referents. The investigation described in this report, based on more than 5 million person-years of mortality follow-up, represents one of the largest cohort studies of military veterans ever conducted.
