But this does not signal any slowdown in Congressional hearings and investigations. As the 2008 presidential campaign heats up, the pundits and politicians will have much more to say about the hot topics on this year's agenda:
FDAAA Implemention The legislative wrangling is over, and now the lawyers are in charge of deciphering what members of Congress really intended for many complex and contentious portions of the FDA Amendments Act [see "Whither FDA 'Revitalization'?]. There is considerable uncertainty about how and when manufacturers will have to file Risk Evaluation and Mitigation Strategies (REMS), especially for high-risk drugs already on the market. FDA has to clarify a process for tracking and enforcing compliance with Phase IV study commitments. And new requirements for registering a greatly expanded range of clinical trials and trial results present a substantial challenge for FDA and the National Library of Medicine.FDA Deputy Commissioner Janet Woodcock indicated that a REMS may not be required for all drugs, in discussing FDAAA at a Food and Drug Law Institute conference in November. The agency will use its REMS authority "judiciously," she commented, noting that too many restricted drug-distribution programs could increase confusion and decrease access to the therapy.
One serious complication when Pharm Exec went to press last month was that FDA could not yet use the added revenues authorized under the Prescription Drug User Fee Act (PDUFA) section of FDAAA. The agency collected the higher fees, but could not spend the money until Congress approved its 2008 appropriation bill, which was caught in the wrangling between Democrats and the Bush administration over federal government spending. Efforts to modernize FDA's IT system and to expand access to outside safety information, among other new projects, may get off the ground very slowly.
Approval slowdown While wrestling with new programs, FDA is under pressure to demonstrate that it has not become overly gun-shy about approving new drugs for market. New drug approvals were down last year, as well as the number of new molecular entities (NMEs). Manufacturers complain that the agency is issuing more "approvable" letters, which demand additional trials and testing before final approval and often lead to narrow indications. Black-box warnings seem to be proliferating, as well as agency safety alerts and advisory-committee reviews of safety issues for certain drugs and drug classes.
FDA has launched a pilot program to reassess the risks and benefits of typical NMEs 18 months after approval. The agency hopes that it can speed up approvals and reduce postmarket crises by identifying ways to detect safety issues earlier in the review process. FDAAA provides FDA with additional tools for assessing product safety before and after approval, but that may not quell the political rhetoric about manufacturer malfeasance and FDA ineptitude.
Imports scrutiny Drug safety issues, along with the concerns generated by contaminated Chinese pet food and toys, have focused public attention on how well FDA and other government agencies can detect and halt the import of dangerous products. The Bush administration issued an Import Action Safety Plan in November that offered few new ideas or funding specifics but provides a basis for Congressional action. Legislators already are raising questions about the quality of foreign drug products and how well FDA monitors the growing volume of drugs and drug substances from China, India, and other countries. Investigators cite inadequate FDA computer systems for tracking foreign manufacturers and for inspecting overseas plants in a timely and efficient manner. There are proposals to authorize FDA curbs on inadequately documented imports and to collect user fees on imports to expand foreign inspections; those revenues also could support proposed FDA satellite offices in China and India.
