In the May 3 issue of the Journal of the American Medical Association, Brian L. Strom, MD, MPH, Professor of Public Health and Preventive Medicine and Chair of the Department of Biostatistics and Epidemiology at the University of Pennsylvania School of Medicine, analyzes the limitations of the current system of drug-safety monitoring and proposes a solution that addresses overly aggressive early marketing practices; an absence of incentives to complete post-marketing safety studies; direct-to-consumer (DTC) advertising that can promote non-critical use of "blockbuster" drugs; the current trend toward delaying drug approval; and public misunderstanding about the safety of drugs.
Strom proposes an alternative approach with three elements: conditional approval, an empowered US Food and Drug Administration (FDA), and a complementary nongovernmental organization.
When a drug is initially approved, it should ideally enter a period of conditional approval, he says. In this period, marketing, especially DTC, would be restricted. Drug labels would need to be clearly marked that the drug's approval is conditional and has only been studied in a limited number of patients. Removal of label caveats would depend on the outcome of subsequent studies and their findings, depending on the numbers of individuals in the studies, and the risk and novelty of the drug, as well as addressing all premarketing safety questions.
"The current system is moving toward a delay in drug approval, still followed by optional postmarketing studies," notes Strom. "Instead, the proposed approach would be conditional approval followed by postmarketing studies required before the condition is removed."
